rbattelle I believe the H. P. is in the neighborhood of 25 to 28.
Edit: I just found a specification that states 36 H. P. @ 1525 rpm and 125 ft. lbs @ 1050 rpm.
The silver thing on the bumper looks like an upside down baking tin, it also acts as the hydraulic pump cover.
The tracks are driven mechanicaly. There is a clutch lever and brake pedal for each side, so when you want to turn you pull the clutch lever and step on the brake and that is the way you turn.

I got it from my dad. He use to use it on his property since the eighties, but moved up to a John Deere 550. So it sat for about five years until I talked him out of it.
All it has cost me so for is $198 to have it move from his place to my place.
Vaughn it is a diesel 4cyl. 3 3/4" bore x 5" stroke. It does have a two cylinder horizontally opposed gas pony motor used to start the diesel.
