Id be pretty disappointed in the tractor PTO clutch. It gets exercised every time its engaged and so be should working nomimally and be sized to protect the tractor gears. That seems a tractor design problem. Really scary what might happen if a little tractor with an improperly designed pto system is running a big implement. One of the 1st times I put the JD bushog on the L2550 Kubota I hit a stump that stopped it dead. The engine bogged but held. I looked back and saw the stationary pto and declutched right away. Everything still works fine - a prompt graceful stop stalls the engine, a hard smack breaks loose the PTO clutch. Slip clutch a bit tight for that tractor. - - My wife smoked the slip clutch on that same BHog the other day using the L3450 we got when we sold the smaller Kub. She was trying to spread out a big pile of leaves to mulch an area. She caught it quick and came to me saying she thot she burned up its transmission cuz it had smoked. Clutch was not terribly hot so I know it didnt slip long. Good catch Baby! In 5 yrs this is the 1st time Ive adjusted it. It must have been slipping incrementally and kept itself in shape. Its multi plate - not like the ones I see these days. Maybe they really knew how to make them in 1960 and somebody retired and they forgot how.john_bud said:Larry,
Seen it. Thankfully, didn't experience it. 2 tractors -1955 Ford 640 and a JD 4300. Both with rotary cutters. The Ford hit a rock or stump, my best friend was running it at the time so I have no reason to doubt it. The JD was one that was getting repaired when I went thru the shop, the service tech told me the owner failed to maintain the slip clutch. He even showed me the clutch and the rust on it. [SNIP]
I don't know at what point tractor damage occurs, I do follow the procedure to varify that the clutch can slip. Maybe it's not needed at all, dunno.
