I just got a 1975 1650 Hydro with the 16hp Kohler engine for my son to use. Man those things are built! It’s in really good condition and everything works right. No smoke or knocks from the engine and the drive works perfectly. It came with the mower deck which is darn near new and a snow blade,,but I believe the blade is from the narrow body older series not the wide body so I will keep my eyes open for one.
I have no doubt that thing would make my 3yr old JD X500 look bad in a pulling contest,,,lol!
I will get a better pic of it later. I just cleaned it all up and the wheels are in great shape and it looks good. The second pic is the same model, but with the engine covers on and totally restored. My buddy restored this one and many others over the years. i figured it would be a good hobby for my son to get into and he likes the tractor shows. Heck I’n gonna use it to plow snow this winter,,lol!
