A skid steer with a 2,500 lb rated operating capacity does not necessarily tip at 2,500 lb.
It also does not mean every 2,500 lb pallet can be lifted to full height, carried across rough ground or placed safely on a truck.
The number on the specification sheet describes a rated operating load under a defined set of conditions. Real work adds other variables: attachment weight, load position, lift height, ground conditions and movement.
Understanding those differences is especially important when comparing wheeled skid steers with compact track loaders.
A tracked machine can have a higher tipping load but a lower published rated operating capacity than a wheeled machine. Nothing is necessarily wrong with either specification. The two machines may be rated using different percentages of tipping load.
This guide explains rated operating capacity, tipping load, the 35% and 50% rating conventions, and how to interpret those numbers when handling pallets, bales, bulk material and other loads on Canadian farms and jobsites.
ROC vs Tipping Load: Quick Comparison
| Specification | What it means |
|---|---|
| Rated operating capacity (ROC) | The manufacturer’s rated load for the machine under specified conditions |
| Tipping load | The load associated with the machine reaching its specified forward tipping condition in a controlled test |
| 35% tipping-load rating | Common rating basis for compact track loaders |
| 50% tipping-load rating | Common rating basis for wheeled skid steers; also published as an additional comparison figure for some CTLs |
| Operating weight | Weight of the machine in its specified operating configuration |
| Lift breakout force | Force available to raise or break a load free under specified conditions |
| Bucket breakout force | Force available through the bucket/tilt mechanism |
| Hinge-pin height | Maximum height of the bucket attachment pivot |
| Lift path | The path travelled by the attachment as the loader arms rise |
These numbers answer different questions.
Do not use operating weight, breakout force or tipping load as substitutes for rated operating capacity.
What Does ROC Mean on a Skid Steer?
ROC stands for Rated Operating Capacity.
It is the manufacturer’s rated operating load for a particular machine and configuration.
For a wheeled skid steer, published ROC is commonly 50% of tipping load.
For a compact track loader, published ROC is commonly based on 35% of tipping load, although manufacturers may also show a 50% reference figure.
The distinction reflects the different rating conventions used for these machine types.
However, ROC is not a promise that every load at that weight can be handled safely in every position or on every surface.
The exact manufacturer’s rating and operating instructions still govern the machine.
What Is Tipping Load?
Tipping load describes a defined stability limit measured or calculated under specified test conditions.
In simple terms, it tells you how much load brings the machine to its forward tipping threshold in that test configuration.
Imagine a skid steer standing on firm, level ground.
As more weight is applied at the front attachment, the load creates a forward-turning effect around the machine’s contact with the ground.
Eventually, that forward effect can overcome the stabilizing effect of the machine’s own weight.
That is the tipping condition.
The precise test arrangement matters, including load position and machine configuration.
Tipping load is useful for understanding a loader’s stability characteristics.
It is not a recommended working load.
Why ROC Is Lower Than Tipping Load
A machine working on a farm or construction site is not sitting still on a perfectly level test surface all day.
It may:
- brake suddenly
- cross ruts
- climb a slope
- turn with a load
- travel over soft soil
- lift a pallet to truck height
- use a heavier attachment than the standard bucket
Each of those conditions can change stability.
The gap between the published tipping load and the rated operating capacity provides a margin, but it does not eliminate those risks.
This is why a machine’s tipping-load figure should never be treated as its everyday lifting capacity.
The 50% Rating Explained
For a wheeled skid steer, a common published rating is:
ROC = Tipping load × 0.50
Example:
Tipping load: 6,000 lb
ROC: 3,000 lb
The machine has a published rated operating capacity equal to half its specified tipping load.
This is a rating convention, not an instruction to work near the tipping threshold.
The 35% Rating Explained
Compact track loaders commonly use:
ROC = Tipping load × 0.35
Example:
Tipping load: 6,000 lb
ROC: 2,100 lb
The machine itself has not become less capable simply because the published number is smaller.
The rating uses a different percentage.
This is particularly important because tracked loaders are commonly used on softer, less predictable ground.
The more conservative 35% figure reflects a larger margin between the rating and the specified tipping condition.
Why a CTL May Show Both 35% and 50%
Some manufacturers publish both figures for the same tracked machine.
For example, a CTL with a 7,000 lb tipping load would have:
| Rating basis | Calculated value |
|---|---|
| 35% | 2,450 lb |
| 50% | 3,500 lb |
Those are two calculations from the same tipping load.
The loader did not gain 1,050 lb of hydraulic capability when someone changed the percentage.
The machine did not receive a larger engine, heavier counterweight or different lift arms.
Only the reporting basis changed.
Do not treat the 50% reference number as permission to exceed the manufacturer’s applicable rated operating capacity.
Why Brand-Based ROC Rules Are Misleading
You may encounter advice such as:
“Bobcat uses 50%, Kubota uses 50%, and John Deere uses 35%.”
That is not a reliable way to compare compact loaders.
John Deere publishes 50%-based ROC figures on wheeled skid steers and 35%-based figures on compact track loaders.
Bobcat has the same broad distinction between wheeled and tracked machines.
Kubota publishes both 35% and 50% values on some SVL specifications.
The correct comparison starts with:
Which machine? Which undercarriage? Which published rating? Which configuration?
Not the badge on the side.
Real Example: John Deere 330 P-Tier
The John Deere 330 P-Tier is a wheeled skid steer.
John Deere Canada lists:
| Specification | Value |
|---|---|
| Rated operating capacity | 2,950 lb |
| Tipping load | 5,900 lb |
| Operating weight | 9,930 lb |
| Lift path | Vertical |
| Hinge-pin height | 132 in |
The relationship is straightforward:
5,900 × 50% = 2,950 lb
This is a concrete example of why it is incorrect to claim that all Deere loaders are rated at 35%.
The 330 P-Tier is not.
Real Example: John Deere 333 P-Tier
Now look at Deere’s tracked machine.
John Deere Canada lists the 333 P-Tier with:
| Specification | Value |
|---|---|
| Published ROC | 3,850 lb |
| Tipping load | 11,000 lb |
| Operating weight | 12,183 lb |
The relationship is:
11,000 × 35% = 3,850 lb
The 330 P-Tier and 333 P-Tier are both Deere machines.
One is wheeled and the other is tracked.
Their ROC figures use different percentage bases.
This is precisely why brand-level generalizations fail.
Real Example: Kubota SVL75-3
The Kubota SVL75-3 is an especially useful example because Kubota publishes both ratings.
| Specification | Value |
|---|---|
| Tipping load | 7,112 lb |
| ROC at 35% | 2,490 lb |
| ROC at 50% | 3,557 lb |
| Lift path | Vertical |
| Hinge-pin height | 122.7 in |
The difference between 2,490 and 3,557 lb is not a physical upgrade.
It is a different percentage applied to the same tipping-load figure.
When comparing the SVL75-3 against another compact track loader, use equivalent rating bases rather than choosing whichever number looks larger.
For the wider Kubota family, read our Kubota SVL Lineup Comparison.
Real Example: Bobcat T66
Bobcat’s earlier T66 compact track loader provides another clear example.
Its North American specifications list:
Tipping load: 7,000 lb
ROC: 2,450 lb
Calculation:
7,000 × 35% = 2,450 lb
The T66 has a stronger published tipping-load figure than several smaller wheeled skid steers.
Yet its 35%-based ROC can look lower than their 50%-based ROC.
Comparing those headline figures without understanding their basis can lead to the wrong conclusion about relative machine stability.
Does Higher Tipping Load Mean a Better Loader?
Not automatically.
Higher tipping load can indicate greater stability under the specified test conditions.
But a loader also needs to satisfy the actual job.
Consider:
- available hydraulic lift force
- lift path
- lift height
- forward reach
- attachment weight
- ground pressure
- visibility
- travel conditions
- trailer weight
A machine with more tipping-load capacity may still be poorly matched to an application requiring long forward reach or a particular attachment.
Tipping load is an important part of the picture, not the entire picture.
ROC vs Operating Weight
These specifications are frequently confused.
Operating weight describes the machine itself in the manufacturer’s specified operating configuration.
ROC describes its rated load.
A skid steer weighing 9,000 lb does not automatically have a 4,500 lb ROC.
Operating weight includes the machine, not its payload rating.
The relationship between weight and stability depends on much more than gross weight.
Machine geometry and weight distribution matter.
ROC vs Hydraulic Lift Capacity
A loader may have enough hydraulic force to raise a load that is too heavy to handle within its rated stability limits.
That does not make the load acceptable.
Likewise, a machine may have enough stability for a load but insufficient hydraulic capability to raise it through the required part of the lift path.
Hydraulic lift force and stability are separate limits.
The usable load must remain within all applicable limits.
ROC vs Breakout Force
This is another common specification mistake.
A loader might have:
2,500 lb ROC
and
6,000 lbf bucket breakout force
That does not make it a 6,000 lb pallet machine.
Breakout force describes force available for a particular digging or lifting action under specified conditions.
It is useful when comparing machines for:
- digging into compacted soil
- loading dense material
- breaking material loose
- bucket work
It is not a substitute for rated operating capacity.
Can a 2,500 lb ROC Skid Steer Lift a 3,000 lb Pallet?
The important question is not whether it can physically raise the pallet an inch.
The question is whether the complete load can be handled within the manufacturer’s permitted limits throughout the task.
A 3,000 lb pallet exceeds a 2,500 lb published ROC before considering any additional complications.
The fact that an operator may be able to make the hydraulics move does not make the operation acceptable.
Use the applicable rated capacity and attachment instructions rather than experimenting to find the tipping point.
Attachment Weight Changes the Calculation
Imagine a loader with a published ROC of 3,000 lb.
Now fit:
- a heavy fork frame
- long fork tines
- a grapple
- a bale spear
- a specialized lifting attachment
The attachment has weight of its own.
It may also position the payload farther forward than the attachment used for the original rating.
Both can reduce the load available for the intended job.
The manufacturer’s ROC remains the published ROC, but the usable payload with a particular attachment may be lower.
Do not automatically subtract attachment weight from ROC and assume the result is a complete safety calculation.
The attachment’s weight distribution and the load centre also matter.
Use the manufacturer’s approved attachment and load information.
The Pallet Fork Problem
Pallet forks make this issue especially obvious.
A bucket often carries material relatively close to the machine.
A pallet may extend much farther forward.
The centre of the load may sit near the middle of a long pallet rather than close to the quick-attach plate.
That creates greater forward leverage.
Two loads with exactly the same weight can therefore create different stability demands.
A compact loader may handle a dense load close to the attachment differently from a large pallet whose weight is centred much farther forward.
What Is Load Centre?
Load centre is the distance from a specified reference point to the centre of gravity of the load.
For a uniformly loaded pallet, the centre of gravity is often near its middle.
But loads are not always uniform.
A fertilizer tote, engine, irregular bale or bundle of material may have its weight concentrated in one part of the load.
A longer load centre increases the leverage on the loader.
This is why actual fork and machine ratings must be checked together.
Simple Fork Example
Suppose a pallet contains:
- 2,000 lb of material
- 150 lb of packaging and pallet
The load itself is:
2,150 lb
Now add the weight and geometry of the fork attachment.
The machine must handle the complete arrangement, not only the product weight printed on the pallet label.
If the pallet is long or unusually loaded, the centre of gravity can further change the stability calculation.
Do not reduce the problem to one subtraction from the headline ROC.
Why Lift Height Matters
A loader may feel stable carrying a load close to the ground.
That does not mean it will behave identically when the arms rise.
As the attachment moves upward, the load follows the machine’s lift path.
Its horizontal position can change.
The centre of gravity of the entire machine-and-load combination also changes.
This is particularly important when:
- stacking pallets
- loading trucks
- lifting totes
- placing materials onto platforms
Use the manufacturer’s guidance for the required lift height and attachment.
Radial Lift vs Vertical Lift
Compact loaders generally use one of two lift-path designs.
Radial lift
The attachment follows a curved path.
Radial-lift machines are commonly associated with lower-height digging, grading and material movement.
Vertical lift
The attachment follows a path intended to provide more useful reach at higher lift positions.
Vertical lift can be particularly useful for:
- truck loading
- pallet handling
- stacking
- placing material at height
The lift path does not replace ROC.
It helps determine whether the rated machine geometry fits the work.
Why a Tall Hinge Pin Is Not Enough
Hinge-pin height describes how high the attachment pivot can rise.
It does not independently tell you how much material can be lifted to that height.
You also need to consider:
- reach at height
- attachment height
- load centre
- hydraulic ability
- stability
- actual dump or placement clearance
A high hinge-pin number is useful.
It is not a full-height payload rating.
Counterweights Can Change ROC
Some manufacturers publish alternative ROC figures for machines equipped with approved counterweights.
The counterweights change the weight distribution.
That may increase the machine’s rated capacity under the specified configuration.
However, the increased rating applies only when the required equipment is installed according to the manufacturer.
Do not use the counterweighted ROC from a brochure for a machine that does not have the counterweights.
Counterweights Are Not a DIY Capacity Upgrade
Adding random steel plates or homemade weight to the back of a loader is not equivalent to a manufacturer-approved counterweight package.
It can affect:
- structural loads
- braking
- handling
- operating weight
- transport weight
- component durability
Only use manufacturer-approved configurations and their corresponding ratings.
Does a Heavier Attachment Always Reduce Capacity?
A heavier front attachment generally consumes more of the loader’s available lifting and stability margin.
But placement matters.
A heavy attachment with its mass close to the machine does not have the same effect as an equally heavy attachment extending farther forward.
This is why attachment weight should be considered alongside:
- attachment geometry
- payload centre
- lift height
- machine configuration
A machine-and-attachment combination should be evaluated as a system.
How Slopes Affect Capacity
ROC should not be interpreted as a blanket allowance for operation on slopes.
Sloped ground changes how the combined centre of gravity relates to the wheels or tracks.
The machine may become more vulnerable to forward, backward or sideways tipping depending on its orientation.
Do not assume that a load within ROC on level ground remains acceptable on a slope.
Follow the machine’s operating instructions and keep loads low during approved travel.
Why Sudden Braking Matters
A moving load carries momentum.
Stopping abruptly can increase the forward tipping tendency.
This is especially relevant when transporting:
- pallets
- feed totes
- bales
- dense bucket loads
The machine may remain stable during smooth travel but behave differently during sudden braking.
That is why controlled movement matters even below the rated operating capacity.
Soft Ground Changes the Picture
Compact track loaders are often chosen for:
- muddy yards
- soft fields
- landscaping
- winter conditions
Their tracks spread machine weight over a larger area.
However, soft ground can still compress unevenly.
The machine can pitch, roll or lose support in ways that are not represented by a simple level-ground capacity figure.
Tracks provide flotation and traction advantages.
They do not make the machine immune to tipping.
Skid Steer ROC for Snow Removal
Snow work is a good example of why ROC needs context.
A loader may be used with:
- a snow bucket
- snow pusher
- snowblower
- snow blade
Some attachments primarily carry material.
Others push material along the ground.
A snowblower places different demands on hydraulic flow and attachment power.
A snow pusher can create substantial resistance even when little snow is actually being carried.
For snow removal, ROC is useful but should be considered alongside operating weight, traction, attachment suitability and hydraulic capability.
ROC for Farm Pallets and Totes
For Prairie farms, pallet and tote handling is a practical reason to care about ROC.
Common loads include:
- seed pallets
- bagged fertilizer
- feed
- chemical totes
- bulk bags
- equipment parts
The challenge is that these loads can be heavy, tall or awkwardly distributed.
Before handling them, confirm:
- The actual load weight.
- The complete attachment configuration.
- The load centre.
- The intended lift height.
- The ground and travel conditions.
- The manufacturer’s permitted load for that arrangement.
Do not assume an empty tote and a full tote create comparable demands simply because the attachment is the same.
ROC for Round Bales
Bale handling introduces another complication.
Bales are not always uniform in weight.
Actual weight changes with:
- diameter
- crop
- density
- moisture
- wrapping
- storage conditions
A bale spear also creates a different load geometry from a bucket.
For farms routinely moving heavy bales, evaluate the specific spear or grapple arrangement with the actual bale weight.
A bale that can be moved close to the ground is not automatically suitable for high stacking.
ROC for Construction Materials
Construction loads can be especially demanding because dense materials are often palletized.
Examples include:
- concrete blocks
- pavers
- roofing materials
- bagged cement
- retaining-wall blocks
These materials can exceed a loader’s ROC quickly.
They may also have a load centre farther forward than expected.
The pallet label and the manufacturer’s machine-and-fork guidance are more useful than estimating weight by appearance.
How to Compare Two Loaders Fairly
When comparing skid steers or CTLs, follow this order.
Step 1: Separate wheels from tracks
Identify whether each machine is a wheeled skid steer or compact track loader.
Step 2: Find published ROC
Record the manufacturer’s actual rating.
Step 3: Find tipping load
This helps you understand the relationship behind the rating.
Step 4: Identify the rating basis
Is the published ROC based on 35% or 50%?
Step 5: Confirm configuration
Look for differences involving:
- counterweights
- cab
- tracks
- attachment
- model year
Step 6: Compare lift geometry
Check hinge-pin height, reach and lift path.
Step 7: Evaluate the actual load
Include attachment weight, load centre and job conditions.
This process produces a more meaningful comparison than ranking machines by their largest published ROC number.
Example: Comparing a Wheeled and Tracked Machine
Consider two hypothetical loaders:
| Specification | Wheeled loader | Tracked loader |
|---|---|---|
| Tipping load | 6,000 lb | 7,000 lb |
| Rating basis | 50% | 35% |
| Published ROC | 3,000 lb | 2,450 lb |
The wheeled loader has the higher published ROC.
The tracked machine has the higher specified tipping load.
Does that mean the wheeled loader is physically stronger in every lifting task?
No.
The ratings were calculated using different percentages.
Does it mean the tracked machine can simply operate at 3,500 lb because that is 50% of its tipping load?
Also no.
For real work, follow the manufacturer’s published operating rating and instructions for the actual machine.
Do Not Turn a Comparison Percentage Into a New Rating
It can be useful to calculate both 35% and 50% of tipping load for analytical comparison.
But there is an important distinction:
Calculated comparison figure ≠ manufacturer-approved operating rating
A comparison table should label calculated figures clearly.
Never silently replace a manufacturer’s ROC with a recalculated number.
Common ROC Mistakes
Mistake 1: Treating ROC as tipping load
ROC is lower than the specified tipping-load threshold.
Mistake 2: Assuming every brand uses one percentage
Rating conventions depend on machine type and published specification.
Mistake 3: Comparing 35% ROC with 50% ROC without noticing
The numbers do not use the same basis.
Mistake 4: Using the 50% CTL reference as permission to overload
The additional reference does not override the applicable manufacturer rating.
Mistake 5: Ignoring attachment weight
Forks, grapples and other attachments affect the complete load.
Mistake 6: Ignoring load centre
A load positioned farther forward changes stability.
Mistake 7: Treating breakout force as lifting capacity
Breakout force and ROC measure different things.
Mistake 8: Assuming full-height performance from ground-level behaviour
The load position changes during lifting.
Mistake 9: Ignoring counterweight configuration
A counterweighted rating may not apply to a standard machine.
Mistake 10: Using level-ground ROC as a slope rating
Ground conditions and movement change stability.
What Size ROC Do You Need?
Start with your heaviest normal task rather than the loader model.
For a farm, that might be the heaviest full seed pallet.
For a landscape contractor, it might be a pallet of pavers.
For a livestock operation, it might be the largest bale.
Determine the actual weight and geometry first.
Then compare machines using the applicable manufacturer ratings for the required attachment and operating conditions.
Avoid choosing a loader that is routinely required to work at the edge of its permitted limits.
If the job cannot be performed within those limits, the operation needs a different machine or handling method.
Final Thoughts
Rated operating capacity is one of the most useful specifications on a skid steer or compact track loader.
It is also one of the easiest to misunderstand.
A wheeled skid steer commonly publishes ROC at 50% of tipping load.
A compact track loader commonly uses 35%, and some CTLs also publish a 50% comparison figure.
That difference does not mean one manufacturer is honest and another is exaggerating.
It means the reader needs to understand the basis of the number.
But even a correctly interpreted ROC is not the entire lifting picture.
Attachment weight matters.
Load centre matters.
Lift height matters.
Ground conditions matter.
Hydraulic capability matters.
The machine’s approved configuration matters.
The best way to compare loaders is to start with the exact job, then check the manufacturer’s rated capacity and attachment guidance for that job.
ROC tells you the rated load. Tipping load helps explain the stability margin. Neither replaces the operator’s manual.

Frequently Asked Questions
What does ROC stand for on a skid steer?
ROC stands for Rated Operating Capacity. It is the manufacturer’s rated operating load for a specific machine and configuration.
Is ROC the same as tipping load?
No. ROC is lower than the specified tipping load. Tipping load describes a stability threshold under controlled conditions, not a recommended working load.
Is skid steer ROC 50% of tipping load?
For many wheeled skid steers, yes. Always confirm the manufacturer’s stated rating for the exact model.
Is compact track loader ROC 35% of tipping load?
It is a common published basis for CTLs. Some manufacturers also publish a 50% reference figure.
Does John Deere use 35% ROC?
John Deere uses a 35%-based ROC on certain compact track loaders. Its wheeled 330 P-Tier publishes 2,950 lb ROC and 5,900 lb tipping load, which is a 50% relationship.
Does Kubota use 35% or 50% ROC?
Kubota publishes both figures on some compact track loaders. The SVL75-3 has 2,490 lb ROC at 35% and 3,557 lb at 50%.
Does Bobcat use 35% or 50% ROC?
Bobcat commonly publishes 50%-based ROC for wheeled skid steers and 35%-based ROC for compact track loaders. Check the exact model and configuration.
Can a machine lift more than its ROC?
A loader may physically raise a load above ROC, but that does not make the operation acceptable or safe. Do not exceed the applicable manufacturer’s operating rating.
Is a 3,000 lb ROC machine suitable for every 3,000 lb pallet?
No. Attachment weight, load centre, lift height and ground conditions must be considered alongside the manufacturer’s ratings.
Do pallet forks reduce usable capacity?
They can. Fork weight and the forward position of the load affect the complete lifting arrangement.
Does a heavier attachment reduce ROC?
The published machine ROC does not automatically change, but the available payload for the actual attachment-and-load combination may be lower.
Does lift height affect skid steer capacity?
Load position changes during lifting, and the machine’s ability to handle a load can vary through the lift path. Follow manufacturer guidance for the required height.
Is vertical lift better for pallets?
Vertical-lift geometry is commonly associated with greater usefulness at higher placement positions, but rated capacity, reach and attachment compatibility still need to be checked.
Is operating weight the same as lift capacity?
No. Operating weight describes the machine itself. ROC describes its rated operating load.
Is breakout force the same as ROC?
No. Breakout force measures force available for a specified digging or lifting action, not the recommended load for carrying or placing material.
Can counterweights increase ROC?
Manufacturer-approved counterweight configurations may carry higher published ratings. Those ratings apply only when the required configuration is installed.
Is tipping load safe to use as a working limit?
No. Tipping load is not a recommended operating target.
How should I compare a skid steer and a CTL?
Compare their actual published ROC, tipping load, rating basis, lift geometry, attachments and intended operating conditions.
Where can I compare compact loaders in Canada?
Browse the Aglist Compact Loaders category for specifications, model comparisons and owner reviews across major manufacturers.
Specifications and ratings vary by model year, configuration, attachment and market. Published ROC figures describe manufacturer-defined conditions and must not be used to override the operator’s manual or applicable attachment limits.
