Sounds like those pulleys are a little expensive.
There is a Cub graveyard about 35 miles from me with acres of Cubs.
Should be able to find one there.

On a Woods 42 changing the mounting holes won't change the belt length. That's why they are at an angle, as you move the deck up the holes from bottom to top, the distance from the PTO to the plane (horizontal) that the spindle pulley runs in gets shorter. At the same time, the distance from the spindle pulley to the plane (vertical) that PTO runs in gets longer by the same amount. Otherwise every time you changed mowing height you'd have to have a different belt. There is a difference between "mowing height", done by the location of which holes the arms are in versus raising and lowering the deck with the hydraulics.

The pulley has been pretty well covered but I haven't seen any mention of with the deck raised the tension comes off the belt. So If you are trying to mow tall stuff with the deck raised the belt will slip more than when it's down. Also when tightening a belt with the mule drive pulleys the deck needs to be horizontal. Tightening the belt when the deck is up and then lowering it will really stress the belt, PTO bearing, and mule drive pulleys.

Thanks, Scrivet, for that info

I don't have hydraulics, just a lifting bar.
You're right in that I was trying to mow with the deck lifted high.

I don't have a lot of room for up and down.
My bar is only moved two notches to put the skids on the ground.
When fully raised, the skids are, probably, less than 2" off the ground
For the first time today I noticed in the instructions that the skids should be off the ground.
I'm not very smart.

The tractor was bogging down when mowing and it makes sense now that I know there was excess drag.

The mower deck should also be adjusted so that the front end is tilted a bit lower than the rear. This also helps reduce the "drag" on the blade since the blade when at the rear of the deck will be slightly above the grass already cut. Stan

Thanks, stan.
Would I be using one of the higher or lower holes on the idler bracket?
Right now I'm in the second hole from the top

Not doubting you but I swear I read that the front should be higher

I just checked again on the 42 manual.
It said for shredding stalks (whatever they mean) adjust the attitude so the front is high.

Had a similar problem with one with a hand lift a couple years ago, ended up drilling another hole in one of the linkages. I never did investigate that much but I think it has something to do with the geometry of the manual lift versus the hydraulics because I took the mower off a tractor with hydraulics and it raised and lowered fine. I couldn't get it very far off the ground with the manual lift at first, but I could have used it for a plow with no problems. Both tractors had the same size tires.

I looked today to see if there was a different way to mount the height adjustment and couldn't see any way

I can't comment on the WAY to adjust the attitude but I think "shredding stalks" refers to cutting corn stalks in which case the front edge would be positioned as high as possible to knock down the standing residue to shred it. I believe on the other hand we're talking about mowing grass. In my original comment to "slightly lower" the front edge of the mower was based on my common sense interpretation of the following instructions and the fact that the "drag" of the blade on previously cut area coupled with the limitations of the hp of the C60 engine would further lower the performance, hence, "lower the front" slightly. Take a look at this page from the 154 Numbered Series LoBoy Mowers Manual, adjustment of height, middle of the page, left side. Click on the image to make it larger, ctrl + will also make it larger.

I don't know if these pics will help to diagnose

This is fully raised

My standard Cub with hydraulics will pick the Woods 42 mower deck quite a bit higher than the photograph. The lift linkage on the right side of the tractor appears correct. Just guessing, the top of my deck is around 10" off the ground at full elevation.

Might take a look at the manual lift linkage/set up.
I have an excuse. CRS.

The bottom of my skids when fully raised are, maybe, 2" off the ground.
I can only lower the bar one notch until the deck is fully on the ground.

I got it from a member here and it was on his Cub, but he had hydraulics.
I tried to figure out from the manual and there were a lot of different machines shown on that one page

Photos of the manual lift set up and linkage. Perhaps someone will see/identify the problem.

Never had a manual lift but seems like your rock shaft should be able to rotate further when lifting. Is there any way to adjust the rocks haft position in relation to the lever?
