THE ACREAGE EQUIPMENT FIELD GUIDE
Deluxe, Premium and model numbers: why tractor names do not rank power
A higher trim level or a bigger model number does not guarantee more PTO power or lift. Kubota’s Grand L70 range shows both cases: a Deluxe model with more PTO power than a Premium, and two Premium models with the same engine model and different ratings. Screen attachments on the published figures for the exact model.

Deluxe ahead of Premium
Kubota’s 2026 catalog lists the L4270 Deluxe at 42 gross and 32.5 PTO hp with 2,756 lb of lift at 24 inches. The L3970 Premium lists 39 gross and 30.9 PTO hp with 2,646 lb. The Deluxe uses a naturally aspirated four-cylinder; the Premium a turbocharged three-cylinder. Premium describes equipment and features, not power.
Model numbers out of order
Sorted by model number, the range runs L3770, L3970, L4270, L4470, L5070, L6070. Sorted by PTO power it runs L3770 (28), L3970 (30.9), L4270 (32.5), L4470 (36.2), L5070 (39.8), L6070 (53), which happens to match. Sorted by lift at 24 inches it does not: the L3970 Premium has less lift than the L4270 Deluxe, and the L4270, L4470 and L5070 share one figure. The first two digits roughly track gross engine power, not PTO power or lift.
Same engine model, different ratings
The L4470 and L5070 Premium both list the V2403-CR-TE5 engine, the same displacement and the same frame. Kubota rates the L4470 at 44 gross and 36.2 PTO hp and the L5070 at 50 and 39.8. For an attachment with a 45-engine-hp ceiling or a 50-hp minimum, the two tractors give opposite answers despite sharing an engine name.
What to check instead
Use the PTO horsepower, engine horsepower and standard, lift at 24 inches and hitch category from the specification table for the exact model and configuration. Treat trim names as equipment packages and model numbers as labels. The same applies across brands: the site’s TYM T474 and T494 share an engine and differ by 1.3 PTO hp and about 1,300 lb of lift.
Take these questions with you.
- What PTO horsepower and lift at 24 inches does the specification table list for my exact model?
- Does a higher trim change the engine, or only equipment such as the display, valves and seat?
- Does a sister model share my engine but carry a different rating?
- Does the attachment rate engine or PTO power, and which of my tractor’s figures applies?
Keep these questions with your exact tractor and attachment details.
