I finally got around to cutting the pto shaft down on my 10' 3pt mower. The shaft would have been ok, but the mower has a slip clutch. So far.. I've just set the limiter on the 3pt lever so i wouldn't raise the mower too high.. but always worried it may slip and then I'd be in fo a big pto repair.
I didn't plan to do it this weekend.. but it's been on the back burner for a while. Came up with some time on staurday and set about pulling the shaft apart and removing the shield. Measured it all up and ended up cutting 4" off each side
( shield and shaft). That worked out perfectly. When it was all back together, I had 3+" of 'extra' compresion available, when the pto shaft was at it's shortest point with the lift up.
I doubt I'll do much running with a 2600# 10' mower dangling inthe air behind the tractor.. but there are a few times when i need to clear a narrow dirt embankment and it would be nice than just dragging thru it.
I will say that that pto shaft material is some tough stuff. I sacrificed 3 good hacksaw blades getting it cut. After cutting, I used my angle grinder to lightly dress the ends, and then a flat file to de-bur. This shaft was kinda ovaled-triangular and keyed as it had 2 points and one flat..
I greased it back up and put it on. Nice heavy shaft.. did i mention that? Must have been 1/4" thick.. and expanded to almost 5' long.. So easy /forums/images/graemlins/grin.gif to hold the twist collar open, and slide it on the tractor stub while holding that monster up.
Now I've got some piece of mind that I can't push my pto stub/seal and bearing in accidentally. My stepfather did this last year on his JD 2240 I had to help him repair it.. split tractor.. replace ind pto clutch.. some locking rings, seals, and bearings. Not a bad job.. but took a couple days and about 500-600$ in parts... I don't feel like going thru that with my tractor..
Did I mention that I thought I would never get those shafts cut? /forums/images/graemlins/wink.gif
