Introduction
The Kubota L4470 and L5070 are both Premium models in the Grand L70 series, both turbocharged, and both able to take the cold weather cab. That makes this a different kind of comparison than choosing between a Deluxe and a Premium tractor. Here the trim is the same, so the decision is about size, power, and one loader capability that only the larger machine offers: a mechanical self-leveling loader. For a prairie operation weighing these two, the question is whether you need the extra muscle and the self-leveling loader, or whether the L4470 already covers your work.
This guide lays out what the two share, where the L5070 pulls ahead, and who each one suits, with Canadian property, loader, and winter work in mind. Both are capable, well-equipped machines, so this is a genuine step-up decision rather than a case of one being clearly better. The short version: the L4470 is the value choice within the Premium range for mixed acreage work, while the L5070 earns its price for heavier loader duty, bigger implements, and anyone who wants the self-leveling loader for pallet and material handling.
The short answer
Choose the L4470 if 44 horsepower and 36.2 PTO horsepower cover your work, and you do not need a self-leveling loader. It has the full Premium package, the turbocharged engine, the multi-function joystick, and the cold weather cab option, and for a great many mixed prairie operations it is enough tractor without stepping up in price.
Choose the L5070 if you want more power for heavier loader and PTO work, run bigger implements, or want the mechanical self-leveling loader that the L4470 cannot have. Its 50 horsepower and 39.8 PTO horsepower give more margin under load, and the optional LM1056 self-leveling loader is a real advantage for frequent pallet and material handling.
The deciding questions are how much power your work needs and whether a self-leveling loader matters to you. If the L4470’s power is enough and you do not need self-leveling, it saves money. If you want more capability or the self-leveling loader, the L5070 is the machine.
What the L4470 and L5070 share
Because both are Premium Grand L70 models, they share more than most cross-shopped pairs.
Both use Kubota-built turbocharged engines and the iHST intelligent hydrostatic transmission with three ranges. Both come with the Premium technology package: the multi-function loader joystick that integrates drive mode, auto throttle, cruise control, third-function hydraulics, and HST response, plus upgraded electronics, optional cameras, and the K-Command display. Both can be ordered in open ROPS or the ProCab, and both are eligible for the factory cold weather cab package with heated glass, a rear wiper, rear work lights, and rear remotes for snow work. Both share the Grand L70’s cast-iron axles, metal hood, and premium build.
So unlike a Deluxe-versus-Premium comparison, the trim, engine type, and technology are the same here. The differences come down to power and the loader options, which is what the rest of this guide covers.
Where they differ: power
The L5070 is the more powerful machine, and the step is meaningful.
The L4470 produces 44 gross horsepower and 36.2 PTO horsepower. The L5070 produces 50 gross horsepower and 39.8 PTO horsepower. That is six more gross and about 3.6 more PTO horsepower, roughly a ten percent increase in the power that turns your implements. Both are turbocharged, so this is a genuine step up in engine size, not a retune of the same block, with the L5070 using Kubota’s V2403 turbo diesel.
Where does the extra power help? Under sustained load: running larger PTO implements, pushing bigger loads with the loader, and working heavier ground. If your implements are at the upper end of what a mid-forties-horsepower tractor handles, or you plan to grow into larger tools, the L5070’s margin means it works comfortably where the L4470 would be closer to its limit. For lighter and mid-range work, both have ample power and the difference is less noticeable. The extra output on the L5070 is most valuable to operators who regularly work near capacity.
Where they differ: the self-leveling loader
This is the capability that most clearly separates the two, and it is exclusive to the L5070 within this pair.
The L5070 can be ordered with Kubota’s LM1056 mechanical self-leveling loader, which keeps the bucket or forks level automatically as the boom raises, with a lift capacity around 2,471 lb. The L4470 is not offered with the self-leveling loader; it uses the LA806 or LA1056 loaders without mechanical self-leveling. Self-leveling matters most for pallet fork work and carrying loads that must stay level, where it saves you constantly correcting the bucket angle by hand as you lift. For anyone moving pallets of seed, fertilizer, or feed regularly, or doing frequent loader cycles where level loads matter, it is a genuine time-saver and a reason on its own to choose the L5070.
If level loader work is central to your operation, this requirement points you to the L5070 regardless of the power difference. If you rarely need a perfectly level load and mostly use a bucket, the L4470’s standard loader is perfectly capable, and self-leveling is not a reason to step up.

Which one fits your work
The L4470 fits buyers whose work sits comfortably within its power, and who do not need a self-leveling loader. With the full Premium package, turbocharged engine, and cold weather cab option, it handles mixed acreage loader and implement work well, and it saves money over the L5070 while keeping every Premium feature except the extra power and the self-leveling loader option. For a typical mixed prairie operation, it is often enough tractor.
The L5070 fits buyers who want more capability. If you run heavier loader duty, larger PTO implements, or work near the limits of a mid-forties-horsepower machine, its extra power gives real margin. And if pallet or level-load handling is part of your routine, the LM1056 self-leveling loader is a capability the L4470 simply does not offer. For larger or loader-intensive prairie operations, and especially those handling pallets regularly, it justifies the step up.
The honest path to a decision: if you want the self-leveling loader, choose the L5070, since the L4470 cannot have it. Otherwise, weigh whether your work needs the extra power. Heavier loader and implement work points to the L5070; mixed work within the L4470’s ample capacity points to saving money with the smaller machine.
Frequently asked questions
What is the difference between the Kubota L4470 and L5070?
Both are Premium, turbocharged Grand L70 models with the same trim and technology, so the differences are power and loaders. The L5070 produces 50 gross and 39.8 PTO horsepower against the L4470’s 44 gross and 36.2 PTO, about ten percent more. The L5070 can also be ordered with the LM1056 mechanical self-leveling loader, which the L4470 does not offer. Both can take the cold weather cab.
Is the L5070 worth the extra money over the L4470?
It depends on your work. If you run heavier loader or PTO tasks, larger implements, or want the self-leveling loader for pallet work, the L5070’s extra power and loader option earn the premium. If the L4470’s 44 horsepower covers your work and you do not need self-leveling, it delivers the same Premium package for less money.
Which Grand L70 models have a self-leveling loader?
Within the Grand L70 series, the mechanical self-leveling loader (the LM1056) is available on the L5070 and L6070, the two largest models. The L4470 and the smaller models do not offer it. Self-leveling keeps the bucket or forks level automatically as the boom raises, which is valuable for pallet and material handling.
How much more powerful is the L5070 than the L4470?
The L5070 produces 50 gross horsepower and 39.8 PTO horsepower, against the L4470’s 44 gross and 36.2 PTO. That is six more gross horsepower and about 3.6 more at the PTO, roughly a ten percent increase. Both are turbocharged, so it is a genuine step up in engine size, most useful for heavier PTO and loader work.
Do both the L4470 and L5070 have the cold weather cab option?
Yes. Both are Premium cab-eligible models, so both can be ordered with Kubota’s factory cold weather cab package, which adds heated rear and side glass, a rear wiper, rear LED work lights, and two rear remotes, with optional Nokian snow tires. For prairie winter work, either can be equipped for the cold.
Which is better for handling pallets and material?
The L5070, if you want self-leveling. Its optional LM1056 mechanical self-leveling loader keeps forks level automatically as you lift, which is a real advantage for pallet work and carrying loads that must stay level. The L4470 does not offer self-leveling, so for frequent level-load handling, the L5070 is the better choice.
