Just picked this up and can't find any serial plate but one on the ROPS. it says HD-4c and 1973 the rest is very hard to make out. The tractor has a 4 cylinder diesel and the radiator is behind the engine. It has a shuttle trans

AC 2200 engine , 3 speed trany , 4 in 1 bucket , pump output about 22 GPM Shuttle trany with torque converter , if everything works OK machine for light work or landscape work , Watch the rear bearings on axles as a weak point , case is known to deform and or cup on timken bearings wear in case . track is next to unobtainable , as sprockets and other under carriage parts ------------- Faith isn't a jump in the dark.

thanks Coke. Thats the info i was looking for. I think something major might have happened cause it looks like it is in great shape but looking at the back someone was pulling something really heavy it is bent up and there are 8 weights stacked on the rear. if she doesnt want to run or move i would probably we wise to part out. hr meter says 278 and the tracks and sprockets would indicate that, they are immaculate. thanks

that 4 in 1 bucket is heavy - the machine without counterweights will walk on front idler without them . machine is light in rear for bucket . Not a bad machine to use - had one for about 10 years - did pins and bushings once as tracks got snaky - i used it mainly for backhoe machine as I have a AC 615 hoe that fits onto tool carrier on rear. Need a decellerator in it or throttle down when changing directions to save wear on unit . Keep reverse speed down to prevent fast track wear . ------------- Faith isn't a jump in the dark.
