I posted 2 pictures of the conrols over in Galleries / Help Identify There is a casting # on the top cover: HF TO-501B There is 2 threaded ports , one on either side of the casting. Its starting to make more sense now what the contols are if they are for a hydraulic control , and I'm starting to think thats what its for . I got a pickup load of old parts with the tractor , one item is a hydraulic cylinder ram that bolts to the front of the tractor and pivots up and down . This part is definately homemade but very heavy duty . There is a roll cage affair with winch and lift arm that swings out on the tractor . I 'll lay out the parts and take a picture later . Its an ugly bugger though , be forwarned . Also there is a pump that either bolts on the front of the crankshaft or on the PTO . It'll be fun figuring out what all this stuff is. The only history I got from previous owner was that he had bought it from an old guy down in Kingman AZ 10 years ago who had built it , but has long since passed away . Could be it was built for use in construction or mining industry around here. It was a dedicated piece of equipment and built for some specific task . I was going to pull the cage off , but first I can use it to put up a metal garage building that will be going up shortly . This old thing has been working hard for over 50 year , why stop now ? Sure wish I knew the history of this rig . Someone put a lot of effort into building it . Everybody who sees it asks me " what the h--l is that thing ? I cant answer that , but its sure handy around the place here. My plan is to work the snot out of it getting my place fixed up this summer and then doing a mechanical refurb and paint job on her , then she can lead an easier life. Bob
