So I brought this tractor home yesterday and have been biting at the bit to get to using it. I put the deck on it and tried running it but the pto seemed to be out of adjustment and not grabbing or staying engaged. I adjusted the play out of it according to the manual. Now the engine really bogs down under load. Its not real noticable immediately after I engage the pto, maybe a slight drop in rpms but when I start to move forward I see a significant loss in rpms, to the point that I have to disengage the pto to get them to come back up.

Oh yeah, This is my first post on here. Any help will be appreciated

well first off welcome to the forum. Does the tractor run fine w/o the deck on it? If it does then you need to look at the deck itself and see if it is binding. Biggest cause of binding is the spindle(s) being frozen. Pull the inspection cover off the top of it and verify that ALL the blades spin freely on their own. You will need to remove the deck blade belt to do this

Thanks for the welcome.


Yeah, without the deck on, it moves and runs fine and its fine with the deck on and pto engaged or disengaged. Things start to go south when the pto is engaged and I'm using the drive motor also.

I ran it last night with the tiller attached to the rear pto and noticed no problems.

lost power old gas, air filter dirty,point need adjusting,main jet adjust if has rough idle adjust that first.

Lean condition check fuel line see hard cracked Fuel filter replace with new.

Decarbon Combustion chamber adjust valves.

New to you tractor lacking in tune-up and service.

There good hints in service manual on this site about power loss in tech section.

Have you checked the engine speed unloaded? I have encountered tractors which act like what you are saying ... points (and hence ignition timing) were wrong, but the real culprit was the 4400 rpm engine speed.

Once hydraulic pressure and PTO load ramped up, it overwhelmed the available HP at 4400 RPM ...

Strangely enough it was plenty strong and ran fine at 3400-3600 rpm ...

Welcome to the forum. When you're doing your tune-up, check your compression and see if it's up to specs. You may have weak cylinder(s). That will also cause this condition. Use the squirt of oil in the cylinders trick to determine if it's valves or rings.

Did you actually engage and drop the tiller? If so, and the engine handled that load OK, it's probably safe to assume the engine is good. So you could concentrate your efforts on the mule drive and deck.
