Hello, my name is ryan benton we have spoken before on a 1950T block.  I have another question for you about a 2150 2wd oliver.  We went to look at one today it was mainly all there minus the 2 front small side curtains.  The motor is locked up on this tractor and it has been sitting for 15 years or so.  The thing that was odd was it would not shift  ranges only side to side.  Also it would not move, like the rearend was bound up.  Is there something that would go wrong with these rearends or is the cluctch disc stuck to the flywheel? Also does this tractor have a parking break  that could keep the rear end from turning?  My number is 812-568-0664 thank you for some help.  Also if this is a serious problem is there any place that handles these parts.
