Introduction
The Kubota L5070 and L6070 are the two largest tractors in the Grand L70 series, both Premium models, both turbocharged, and both available with the mechanical self-leveling loader that the smaller machines cannot have. At this end of the range, you are choosing between two well-equipped flagships, and the decision turns on two things: how much power you actually need, and whether you want the cold weather cab, which only one of these two offers. For a larger prairie operation weighing the top of the Grand L70 line, those are the questions that matter.
This guide lays out what the two share, where the L6070 pulls ahead, and who each one suits, with Canadian property, loader, and winter work in mind. Both are capable machines with the full Premium package, so this is a decision about how much tractor you need rather than a case of one being clearly better. The short version: the L5070 is enough flagship for many larger operations at a lower price, while the L6070 earns its place for the heaviest work, the most demanding PTO tasks, and buyers who want the factory cold weather cab.
The short answer
Choose the L5070 if 50 horsepower and 39.8 PTO horsepower cover your heaviest work, and you do not need the cold weather cab. It has the full Premium package, the turbocharged engine, and the option of the self-leveling loader, and for many larger acreages it is enough tractor without paying for the flagship.
Choose the L6070 if you want maximum power for the heaviest loader and PTO work, run the largest implements, or need the factory cold weather cab, which the L5070 is not offered with. Its 60 horsepower and 53 PTO horsepower are a large step up, and the cold weather package makes it the flagship built for serious year-round prairie work.
The deciding questions are how much power your heaviest work demands and whether you want the cold weather cab. If 50 horsepower is enough and you do not need the winter package, the L5070 saves money. If you want the most capability or the cold weather cab, the L6070 is the machine.
What the L5070 and L6070 share
As the two top Premium models, they share nearly everything except power and one cab option.
Both use Kubota-built turbocharged diesels and the iHST intelligent hydrostatic transmission with three ranges. Both come with the full Premium technology package: the multi-function loader joystick, upgraded electronics, optional cameras, and the K-Command color display. Both can be ordered with Kubota’s LM1056 mechanical self-leveling loader, with a lift capacity around 2,471 lb, which keeps forks and buckets level automatically as the boom raises. Both offer the ProCab with its four-post design and rounded glass, and both share the Grand L70’s cast-iron axles, metal hood, and premium build. On the self-leveling loader, which separates these two from the smaller Grand L70 models, they are equal.
So the differences here are narrower and clearer than lower in the range: power, and whether the cold weather cab is available. That is what the rest of this guide covers.
Where they differ: power
The L6070 is significantly more powerful, and this is the largest single step in the Grand L70 lineup.
The L5070 produces 50 gross horsepower and 39.8 PTO horsepower. The L6070 produces 60 gross horsepower and 53 PTO horsepower. That is ten more gross horsepower and, more importantly, over thirteen more at the PTO, roughly a third more PTO power on the L6070. Unlike the incremental steps lower in the range, this is a substantial jump, and it is the reason the L6070 sits clearly above the L5070 as the series flagship.
Where does that power matter? Wherever you work near the limit: running the largest PTO implements, big rotary cutters, large snowblowers, heavy tillers, and pushing the heaviest loads with the loader on demanding ground. The L6070’s extra output gives it real headroom for work that would have the L5070 laboring, and it suits operators running larger implements or working bigger acreage where sustained power counts. If your heaviest tasks sit within what 50 horsepower handles comfortably, the L5070 has ample power and the L6070’s extra output would sit unused much of the time. The flagship’s power earns its keep for those who genuinely work it.
Where they differ: the cold weather cab
For Canadian buyers, this difference may decide the choice on its own.
Kubota offers the factory cold weather cab package on the L6070, but not on the L5070. Within these two flagships, the cold weather package, which adds heated rear and side glass, a rear wiper, rear LED work lights, and two factory-installed rear remotes for snow implements, plus optional Nokian snow tires, is available only on the L6070. This is a genuine and perhaps surprising split at the top of the range.
For a Saskatchewan, Alberta, or Manitoba operation running a tractor through winter, this makes the L6070 the flagship built for the job. Snow work with heated glass front and rear, rear remotes for a blower or blade, and snow tires is a real advantage in prairie conditions, and it is not on the table with the L5070. If winter work is central to your operation and you want the top of the Grand L70 line, the cold weather cab availability points you firmly to the L6070, regardless of whether you would otherwise need its extra power.

Which one fits your work
The L5070 fits larger operations whose heaviest work sits within 50 horsepower, and who do not need the cold weather cab. With the full Premium package and the self-leveling loader option, it handles heavy loader and implement work well and saves money over the flagship. For a large mixed prairie operation that does not run the biggest implements or need the factory winter package, it is often enough flagship without paying for the top model.
The L6070 fits operations that want maximum capability. If you run the largest PTO implements, work the biggest acreage, or push the heaviest loads regularly, its 60 horsepower and 53 PTO horsepower give headroom the L5070 does not. And if you run through winter and want the factory cold weather cab, the L6070 is the only one of these two that offers it. For a serious year-round prairie operation at the top of the Grand L70 range, it is the machine.
The honest path to a decision: if you want the cold weather cab, choose the L6070, since the L5070 is not offered with it. Otherwise, weigh whether your heaviest work needs the flagship’s considerable extra power. The largest implements and heaviest loads point to the L6070; work within 50 horsepower without the winter package points to saving money with the L5070.
Frequently asked questions
What is the difference between the Kubota L5070 and L6070?
Both are top Premium Grand L70 models with the same trim, technology, and self-leveling loader option, so the differences are power and one cab option. The L6070 produces 60 gross and 53 PTO horsepower against the L5070’s 50 gross and 39.8 PTO, roughly a third more PTO power. The L6070 can also be ordered with the factory cold weather cab, which the L5070 cannot.
Is the L6070 worth the extra money over the L5070?
It depends on your work. If you run the largest implements, work the heaviest ground, or want the factory cold weather cab for winter, the L6070’s considerable extra power and the winter package earn the premium. If 50 horsepower covers your heaviest work and you do not need the cold weather cab, the L5070 delivers the same Premium package and self-leveling loader for less.
How much more powerful is the L6070 than the L5070?
The L6070 produces 60 gross horsepower and 53 PTO horsepower, against the L5070’s 50 gross and 39.8 PTO. That is ten more gross horsepower and over thirteen more at the PTO, roughly a third more PTO power. It is the largest single step in the Grand L70 range and the reason the L6070 is the series flagship.
Do both the L5070 and L6070 have a self-leveling loader?
Yes. Both can be ordered with Kubota’s LM1056 mechanical self-leveling loader, with a lift capacity around 2,471 lb, which keeps the bucket or forks level automatically as the boom raises. On self-leveling, the two flagships are equal, and both stand apart from the smaller Grand L70 models that do not offer it.
Which of the two has the cold weather cab option?
Only the L6070. Kubota offers the factory cold weather cab package on the L6070 but not the L5070. It 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 at the top of the Grand L70 range, this makes the L6070 the flagship to choose.
Which is better for a large prairie farm?
It depends on your implements and winter use. For a large operation whose heaviest work sits within 50 horsepower, the L5070 covers it with the full Premium package and self-leveling loader. For the largest implements, heaviest loads, or year-round winter work, the L6070’s extra power and cold weather cab option make it the better fit. Both are capable flagships; the L6070 is the choice when you need the most.
