I have a 1980's vintage Kubota B6100E diesel, 2wd with a Woods 48 inch belly mower attached via belt to the front PTO kit clutch. I used the mower for several years until the shaft spines became so rusted they had insufficient connection to the crank-shaft flange. I couldn't find a replacement shaft, so I towed a pull-behind mower for a few years, leaving the belly mower in the barn.
Finally I just had a new shaft made with new splines mating to a new crankshaft flange.
Now the new shaft on the B9310 clutch assembly is connected, but the clutch won't stay engaged.
When I throw the switch, it runs for 1 to 2 seconds then disengages. And not always. Mostly turning the switch on does nothing. This is whether or not a belt is attached, so it isn't the resistance to the clutch, or even the RPM that seems to kill the engagement.
I can test the load on the clutch by resting my foot on the clutch and feel whether it engages or not. When it does, it still disengages in a few seconds. Most times it's dead.
Any ideas? I haven't replaced the switch or the wires yet. It seems to be more time/load related than a short in the wiring but I could be missing something.
