IH 400 or 450 with pto on side

IA Roy · Dec 9, 2015

I got to thinking about the unit that had the pto shaft in the location where the belt pulley would be located. Someone cautioned against trying to put too much of a load on it if using. If I remember right when the tractors were tested on the belt, that is where they got the maximum power out of. Am I wrong assuming that they were designed to put out full power on the belt for extended periods of time just as the pto on the rear of the tractor was?

Roy.you are correct. "Full power"!

With respect, what was said in the post showing the PTO stub is that at 540 rpm of that stub, the tractor is at half throttle or less, thus not generating full power.

Not familiar with your set up, but you can research belt horse power ratings, get an idea what the belt(s) are capable of handling. You will notice the ratings are for electric motor HP, they get derated for reciprocating engines.

I wouldn't go so far as to say 100% power available at the pto (at least for all machines - maybe the IPTO 400 and 450, too). The manual for my 886 covers 986 and 1086 also. Those are all rated at implements needing no more than 85 horsepower. A 1086 is lots more power than that. Of course, we aren't talking about the same driving mechanism. My old M probably could give its best full power out of the pto - it's just a shaft and some gears in there.
