 Topic: Off color woods mower problem.
Posted: 05 Oct 2017 at 6:19pm |
|
Here is the deal. My Dad has a cub lowboy that has a woods belly mower on it. Everything has worked fine until recently. When he engages the mower the drive pulley on his tractor squeals and won't drive the mower. The tractor will quit. We checked the belt, mower spindles and the tightening pulleys and they are all free and tight. No wobbles or signs of wear. If he engages the drive without the mower belt hooked up it will sometimes squeal alittle but the pulley shows no wobbling or play. He does have a small leak so he is thinking maybe the fluid is low. Or is there something inside that will bind up under stress? Any thoughts please?

Do the mower spindles turn freely with the belt disconnected? Sounds like one could be locked up for some reason.

All spindles are free with belt disconnected. We checked that right away. Thought something was froze up. Can't find anything. Unless something is binding under pressure.

If I remember my cub right that pully on the tractor has two small bolts on both sides of the pto shaft. They tighten a tapered sleeve that keep that all that tight and turning. Id check those bolt to see if they have came out or are just loose allowing that pulley to spin on that sleeve. I don't remember exactly how the bolt go know though. But it place to start

Check for debris in pulley. Around here, Gumballs love to get between the pulley, and belt...

What model low boy is it? 154 , 184, 185 or the offset cub?
There are bearings on the drive shaft for the PTO that comes from the engine, they could be bad.
if its the off set, could be a bearing on the pto shaft out the back of the tranny

It is the offset red model. Will have to do some more checking.

Sounds like the problem is in the tractor, not the mower.
GOOD Morning buddy! We've gotta have breakfast one of these days...

We removed the belt and ran the pto. Sounded smooth and no wobbles on the pto pulley. No idler pulley.

well, you missed something. It is not a complicated system.. Have you ever used a screw driver or pipe as a stethoscope to listen for noises ? Run the belt and set the long thin pipe up against the bearing housings and hold the other end up against your ear... ONE of the bearings is bad if your having a noise.. You SHOULD be able to FEEL it by rotating each spindle separate. May not HEAR the noise at low speed.

IR thermometer can also help diagnose bad bearings...

I have had a couple cubs with belly mower and they had two idler pulleys below the pto pulley, have you checked them when you had the belt off? Leon

This is a head scratcher. Please let us know what you find out. I think it's the tractor--not the mower. Problem only occurs with load on the pto--so that's where I'd focus my effort.

With the tractor turned OFF, and belt pulley engaged, try turning the pulley.
If it doesn't turn, try turning with a greater force to see if it is slipping on the belt pulley shaft.
If it still won't turn, then put the belt pulley out of gear, then see if pulley turns freely.

You've got a bad bearing somewhere in the mower.

We pulled the belt idler pulleys off and checked them. Have been gone for the weekend but we plan on taking off the belt and checking all the spindles one at a time and go from there. There is something binding up I think and should not be that hard, but I tend to live under Murphy's law. I will try all suggestions and if I find the problem will for sure post it. Thanks for all help!

Update. Well my Dad just called and said he was at his cabin and had to move his tractor. As I would have done he tried the mower. Everything worked as it should no noise or squeals. Said he mowed everything he usually does and put it away. I know there is something that was binding and will explore that at a later date but for now I have bought some time. I will be asking some orange questions in the future as I have bought a B that needs some work. Thanks again.

Well, it's nice to see that it's working, but as you state, the problem isn't solved........YET.
When the tractor was parked, was it on top of a tree stump? That would have stopped the blades from turning?! Or on a fence post?
Weird how just moving it a few feet and it works....?
