In my manuals they say 27hp. I also have a yanmar YM3000 that they say is 33. The 950 runs a larger engine that seams to have more guts to it. The deer runs a 3T90J yanmar engine and the yanmar runs a 3T84. Think the deer is rated in hp to the drawbar, not engine hp. If I had to guess, I'd bet the deer has in the 36+ range. They have a listing in tractordata.com. @27
