Sounds like you would be a good match for that 7800--go ahead--get one. I doubt it is even availalbe two wheel drive. Kubota usually put a 4WD decal somewhere on their machines. You might also notice the 4WD lever on the fender. Trust us it is 4WD. Go see one and you will see the advantage of Kubota's bevel gear drive. It is very rugged and maintenence free except for fluid changes. I think since--here it goes--that Kubota kinda started the 4WD compact craze it is expected the tractor is 4WD unless it says to the contrary. Kubota kind of does their own thing, backwards engines in some models, bevel gears, 4WD, boomerang pedals or front rear pedals, single lever joy sticks and other neat things. Good luck. J
