WHAT IS THE HP OF A 190. I READ SOME PLACE THAT IT WAS ONLY 65HP.
WOULD A D21 MAKE A GOOD FARM TRACTOR.BETTER THEN A 190 OR 185.

A 190 gas is rated 63.10 drawbar hp while a one-ninety xt gas is rated 76.65 drawbar hp. a d-21 is rated 93.09 drawbar hp. The d-21 is a much larger tractor than the 185 63.82 drawbar hp diesel.

Guys; forget drawbar horsepower; it can't be MEASURED. Tractors/dozers etc are rated in PTO (shaft) horsepower. Drawbar HP is a CALCULATION; I've done thousands of them as a Design engineer. PTO horsepower is measured using a CALIBRATED (PTO) dynomometer; if your tractor (dealer) doesn't have one (some of these dealers have NEVER HEARD of PTO dynos), keep going down the "block" 'til you find a mechanic who knows what a PTO Dyno is and how to use it. OR call
me @ (801) 920-1214; if you're close to Eugene,OR
I'll run ANY PTO ENGINE (for a fee, of course) on my VERY CALIBRATED DYNO.
