I appreciate the helpful trouble shooting. I was out playing in the dirt with it tonight and it was doing okay and I didn't notice it at the time, but the temp at the pump went to 200+ again. Right now I want to get the fittings and the gauges to check the pressure in the system. This machine does not have a valve on the floor board. Right hand controls all the bucket movement, left hand steers and controls forward and backwards. there isn't a return line directly from the right hand valve (bucket controls) Where the fluid exits that valve it goes over and 't's into the supply line for the directional controlling valve. Then the fluid is routed out the one "out" hose on the travel (left) side and that igoes into a 't' fitting with the used fluid from the wheel motors and then into the filter and then to the tank.
