List prices are the manufacturer’s published figures, re-checked daily; they exclude tax, freight and dealer setup.
A side-by-side reference of each model's stated specifications. MowerFacts doesn’t give opinions: where a published, spec-derived rule can separate machines we mark a Data Pick and show the rule; here, read the values and decide what fits your needs.
Best suited for
What each model is built for, from its duty class and key specs. This is a neutral reference — MowerFacts does not rank one model above another.
- John Deere X750 Signature Series Lawn Tractor — prosumer: larger home properties and light acreage; 48-inch deck; gas powered
- Kubota GR2020G — commercial: daily paid use and high acreage; 48-inch deck; gas powered
What’s different? The 5 differences that matter most, from the published figures.
- X750 Signature Series Lawn Tractor has a K90 hydrostatic integrated with transaxle transmission; GR2020G has a Kubota HST transmission. The transmission grade tracks duty rating and speed. Grade names are each maker's own and are not comparable across brands.
- X750 Signature Series Lawn Tractor has a 60.6 ci (993 cc) engine; GR2020G has a 38.1 ci (624 cc) engine, a 22.5 ci difference. Displacement is the engine's size, not its output. A larger engine is not necessarily a more powerful one.
- X750 Signature Series Lawn Tractor has a published top speed of 8.5 mph; GR2020G has a published top speed of 6.2 mph, a 2.3 mph difference. Top speed is the maker's maximum in transport. Mowing speed is lower and depends on grass, terrain and the deck.
- X750 Signature Series Lawn Tractor has Shaft or AutoConnect drive; GR2020G has Belt drive.
- X750 Signature Series Lawn Tractor has a 24 hp engine; GR2020G has a 20.5 hp engine, a 3.5 hp difference. Published horsepower is the maker's rating at a stated engine speed. It is a different measure from displacement, and two engines of equal rating can pull differently.
