It was a nice sunny day to work on the tractor.  We were able to get rid of some problems / potential problems, but it did not fix the PTO operation.

 

Draining the transmission oil.JPG (688136 bytes) After speaking with the nice folks at Bell Rental and Sales about our PTO problem we decided to drain the transmission and replace the filter on the hydraulic pump.  If it was clogged it could cause the symptoms that we were having.  The oil on the dipstick looked slightly dirty, but it was difficult to tell.

Front transmission drain hole.JPG (244169 bytes) It took a few moments to clean the build up of crud from around the drain plugs and break them free.  We made sure that we could get both of them loose as well as the fill plug before draining. We started draining the front one first. 
Goo we drained from the transmission.JPG (394690 bytes) What came out was pure crud! The new oil is almost clear!
Rear transmission drain plug.JPG (721899 bytes) The rear was just over 5 gallons.  We filled the first pail 2/3 full and slid the second one under.  We lost just a few drops.
Clutch adjustment.JPG (572795 bytes) The clutch free play adjustment was way off so we adjusted it closer to the specs while we were draining the oil.
Transmission fill plug.JPG (597220 bytes) After draining the oil and replacing the drain plugs we removed the access cover for the filter.  It had been sealed with a gasket cement and was difficult to remove. 

The filter was totally plugged with the same crud as in the oil and had quite a few metal particles covering it. (Here is what the old one looked like) The replacement went on without any problem.  We removed the sealer from the transmission and cover and cleaned out any metal particles and crud we could reach from the access cover and then reinstalled the cover using the cork gasket that we had purchased.

After filling the transmission with 11 gallons of Permatrans III through the fill hole pictured we hooked up the rotary cutter and gave it a try. It did not work any better, but the brake squeal went away. This tractor has wet disk brakes that run in the transmission fluid. The breaking action seemed to be smoother and more positive after running the tractor for a few minutes.
