I have a 3010 diesel that when mowing with a 7 foot rotary mower in heavy grass the PTO clutch has slipped. In lighter grass there are no problems and the mower clutch will slip if needed.

In searching this forum there is an exploded view of the clutch assembly. After removing the lower inspection cover it would appear that there are three bolts that apply pressure to the PTO clutch through the levers and the "throwout bearing". It would appear that these could be adjusted for more pressure, but I have been told the only fix is to split the tractor. I just can't believe that a the clutch cannot be adjusted for wear in some way. Am I missing something?

Another quick thing I would mention is the bearing has to be greased or it will go out. On our 4010 you have to remove the inspection cover and try real hard to get the grease hose on the fitting. A big improvement on the 4020 it has a rubber hose that goes from the bearing to the outside of the tractor for easier greasing. Dad constantly complains about Deere’s PTO design and how the bearing has pressure on it the whole time the PTO is engaged.

As Kent mentioned, adjusting the rod on the linkage under the dash should achieve more clamping force on the PTO clutch disc...............

The three bolts you refer to that connect/thread into the PTO pressure plate are set/adjusted during assembly of the clutch to achieve a specified height on the PTO clutch fingers............there is a SMALL chance they weren't adjusted properly during assembly and by adjusting them(counter-clockwise) equally you may be able to gain additional clamping force, THAT IS if you can even access the lock nut for the bolt(I've never tried it before!)............

how hard is it to apply the pto clutch should take about 70 lbs of hand pressure to kent said there is some adjustment under the dash.

Springs in the clutch assy. control pressure. As long as your fingers are not touching the throwout bearing full pressure is being applied. If the fingers are touching some adjustment may be possible ? When replacing the clutch put in NEW springs too.

When the PTO is engaged the fingers are touching. When disengaged the fingers are not touching. From what I am looking at the fingers have to touch in order to engage the PTO.

After I hit the final button I wondered if I had it wrong/backwards for that model since they have the hand lever to engage them. There has to be some adjustments for that lever engagement proceedure.

remove the lower dash cover you will find a rod that runs from PTO lever down thur clutch housing to the pto fork and brg unhook rod at the lever loosen lock nuts on the rod shorten rod one turn and try it should do it the pto brake is mounted on front trans case must split at front off trans case and back off clutch housing for clutch work you split at rear off engine and frount off clutch housing Kent

From what I have read here and other places the adjustment for the engagement lever is just for the lever force, it really does not apply more force to the actual clutch. Is this true? I am guessing about 50 lbs or more anyway, but did not put a scale on it.
