Update: We have had some time to mess around with this tractor again. We pulled the motor and it was a basket case rust everywhere. So we found a 2-155 white motor that was in a lot better shape. We are in the process of rebuilding that engine to stick in the 2150. The 3 speed has been a challenge to find ours had sat full of water for probably 20 years and the input and output shatfs were shot. Still looking for parts or a hole unit, i have my finger crossed.  We also drained the rearend wich was supposed to have already been done but had not happened.  It had about 3 gallon of water in it. One planetarie had a little water in it but the other was good. So the hydraulic unit is comming off for an inspection I have my fingers crossed. We also removed the transmission cover to look at the gears. Despite a little surface rust on the tops of the gears they looked great.  We cleaned the gears and lubed everthing real good, so i hope that that part is ok.  Also rebuilt the telescope and tilt steering wheel. It was frozen solid and would not do anythiing. Radiator is also ready to go back. I think everything is going to have to be rebuilt on this but we like to tinker with them. Oh well !!! Pics to follow.
