Oh, the endless joys of Kubota products.....I posted this on Plowsite too but thought I might get more hits over here. I have a B3030. The 4x4 doesn't work. When shifting, I can feel the gears shift in to each other. So I'm assuming the problem is after the transmission. Maybe a busted driveshaft, broken gear etc in the front end? I looked at an assembly diagram for the 4x4 system. It's over my head, lot of parts in there. Anyone know these tractors well enough to point me in the right direction? This tractor has been a POS since day one. Bought it used from some Amish guy.....NEVER trust the Amish. To add insult to injury, guy I bought it from filled the rear tires with WATER. That's all well and good in warm climates. Tires are frozen solid, literally. The thing has zero traction. I got it stuck in the grass today. Yes, stuck in the grass, not snow, not mud, but grass. Anyone wanna buy a piece of crap Kubota? Some key features: Underpowered, crappy hydro trans, weak ass loader, crappy 4x4, hard to start, slow, pathetic 3 point lift ability. Comfy seat though.
