Checking PTO shaft length?

GSS · Jul 1, 2003

Just got my Woods BB72 delivered yesterday! About time... I didn't have time to hook it up though, but I did get through the manual. However, nowhere does it say anything about checking the PTO shaft length. I know this is necessary, but how is it done correctly? My RFM was setup from the dealer.

I seems to me that lifting my RFM causes the shaft to shorten slightly. So, I suppose I could hook up the BB and adjust it to the desired cutting height and fore/aft lean with no shaft, raise it as high as it will go, measure from each splined shaft's spring pin catch groove (??) on the tractor and mower, and then compare this measurement to the supplied PTO shaft completely compressed (ie its shortest length). If it doesn't get that short, then I got some cuttin' to do! How's that sound? What did I miss?

I tried searching the forums, but no 'how to' info.

Thanks! /forums/images/graemlins/laugh.gif

I cant immediately help you but...I just got a snow blower that hadnt been setup and it was clear the PTO shaft needed to be trimmed. The dealers tech has to stop by to do a warranty repair and will cut the shaft also. When he does Ill watch and see how he does it. then report back. THe manual that came w/ the blower did have some general guidelines for cutting the shaft but nothing detailed along the lines of this is how you determine the length needed.

Gerald, instead of some of us trying to describe how to do it, just go to Bush Hog's Squealer Manual and go to pages 9 and 10 for instructions with pictures. Even though it's a different brand, it should be done the same way.
