When engaging or disengaging the PTO clutch at low speed, the engine stalls.
It appears the blade brake isn't releasing completely before the clutch engages, and the clutch isn't disengaging completely before the blade brake is engaged.
The only adjustment I can see is on the outer part of the clutch cable where I attaches to the bracket next to the battery. Adjusting that didn't solve the problem. It only sets the free play in PTO clutch control lever.
How can I get the PTO clutch to operate without stalling the engine?

Roger,
If the clutch can be adjusted to solve the problem this should cover it;

My tractor doesn't have that adjustment. Is there a fix?

Sorry Roger,
I didn't remember there were two style clutches depending on unit serial number. I went back to my service manual and found no mention of this non-adjuster style clutch, It has been many years since I last worked on one of these and my mind is drawing a blank.
Looking at the parts breakdown the only part that may cause this is #16 clutch spring (loss of spring tension), But that is only my guess without seeing yours up close and personal.

Sorry again I'm not more help, Maybe someone that has worked on one recently will chime in and lend you a hand.
Good Luck

This may sound stoopid on my part,,,, But at slow speed, is there enough horsepower to spin up all the blades & belts & stuff??? I know on my tractor it kills the engine if you engage the blades @ 1/2 throttle or less...If it's always been like that,, only engage the blades @ high RPM,, If not it may even be a carb problem.....Roger

Good point Roger,
It's also possible it's only running on one cylinder (fouled/bad plug) ?

I don't have the mower deck installed, and the engine is running fine.
I just bought the tractor. It had been sitting in a barn for five years. The previous owner had just parked it after the starter quit working. He had removed the mower deck to use the tractor for pulling a cart around. I'm in the process of checking it out after fixing the starter and getting it running again.
I'll just wait and see how it works when I put the deck on.
