I bought my B7100DT 30 years ago and have used it non-stop for snowblowing, mowing, rototilling, wood hauling, and a lot more. The power and versatility of this little workhorse still amazes me.I have had very few problems with this tractor and actually my current problem is not with the tractor per se...it's with the snowblower. I use a Kubota B-222 "rotary snow plow" as the manual put it. But the unit is not orange-it is red and white ,with a McKee makers logo on it and the plates ID it as model 220, serial no. 528. but all pics and info in manual are a perfect match. Anyway... to my problem... I stripped the teeth on the shaft from the snowblower to the front PTO, and cant find a replacement for the life of me. (kubota part no. 70060-00249) nobody has it and I looked for days.My actual shaft is OK, but the 2" splined part that is welded to it is stripped. Does anyone have anything that will fit the tractors splined shaft? Would the spline coupler from a dead PO pump work? could I cut it off and weld it to my shaft? I'd consider an electric PTO clutch if I could find one. The only possibility I found so far is a new PTO pulley with bolt -on male splined protrusion that is mated to a new matching female splined shaft that would then accept my current pulley and mounting bracket- but its over $300 and a lot of work to make it happen-does anyone have any suggestions? Ive read the past few years of posts here and I just know one of you guys is clever enough to beat this one. Please help if you can, thanks, Michael Tobey
