Yanmar Not Working

Scott	I've got a Yanmar YM3110. While bush hogging the other day the tractor quit moving and the hydraulics holding the cutting deck lowered the deck. I checked the fluids and all seemed to be okay. After about 30 minutes I cranked the tractor back up, I was able to raise and lower the bush hog and the tractor moved again. After about 15 minutes of bush hogging everything stopped working again. The motor was still running but it would not move nor could I raise and lower the bush hog. Any ideas??????
Danny	I would remove the hydraulic screen from the transmission, clean and replace. Danny
Scott	Where is the screen located? Is this a "Do It Yourself" type job?
Al	That's a nice tractor that deserves to be serviced properly. The fluid and spin-on filter should be changed and the screen cleaned every 500 hours. For the latter, search underneath for three bolts in a triangular pattern around a couple inches apart. With the fluid drained, undo the bolts and pull out the screen, noting how it went in. Clean and replace. Buy a manual for an equivalent export model, or see if Murray Publishing has one for yours.
Scott	There are not three bolts in a triangular pattern. However, there are five bolts in "dice" pattern with the center bolt being a little larger than the other 4????
