IH 660

mmkid · Jul 13, 2022

Hi. Pull a 660, it weighs 9400. It has 23.1x26
Back tires, and what looks like big weights

Around the back axles. Are those removable, or

No, I see pictures here and there of other

660s pulling lighter classes. Any other weight loss help?

Thanks

if you post a picture of your inner hub , then a person could tell. i think that is the hub your talking about. they used to have after market cement weights for the outside of hub also. if it has the belt pully setup that can come off also, but thats only about 100 lbs. what weight are you trying to get it to would help also, under 8500 ??? and is this antique pulling ?

I dont know for sure but a 660 engine may fit in a 560. So its highly possible that the other guys are running a 560 with a 660 engine and calling it a 660. Its been known to happen. lol

I looked it up and a 560 and a 660 has the same engine. The 660 is turned up more to make more power. I guess 660s also have planetary rear ends so they will be
heavy. The other pullers are probably 560s or even 460s

bull, you can tell or i can tell as soon as i see each tractor. and they both have the same 282 engine. 560 is 1800 rpm, 660 is 2400 rpm.
only difference is the pump . where is this kid to give us some info. ? post and disappear. info is nice for good information. i asked before
what he is doing and no response. just a time waster like kijiji people.

Did the 560s only turn 1800 or was that at pto speed. We have a 560 diesel thats been turning 2700 for years.

yes, 560 is 1800 rated load speed and 660 is 2400 factory load speed.
