I recently borrowed a 80's era, badly neglected Kubota B5100 4WD. When you drive the front end will suddenly lock up. Back up a bit and keep going and you're good for a few more feet. It will do this both forwards and backwards. On closer inspection it is missing several bolts that hold the front frame to the engine. I'm wondering if the flexing of the front end is the cause of the front diff locking up, or if it's a separate repair issue. The bolts are broken off in the engine, so they will have to be drilled out and re-tapped. Since it's not mine I'm hesitant to put a lot of work into it only to find more trouble.
