Well, you say they are cracked, would be better to have new ones on hand when those break instead of having the machine down for days.
I just ordered from Jacks with credit card 05/02. Order wasn't shipped out till 05/09... If waiting isnt a problem... well, you know

Are the belts slipping?

Hi Bill,

No, I don't think the belts are slipping, yet.

The little I know about changing belts is on my 1333 snowblower. If cracks are visible, the belt doesn't have much left. But mower belts probably don't take the kind of pounding that snowblowers do.

johninmd is probably right. Should get new. Maybe get new blades too.

Thanks!

I think I'd mow once and see if the belts have gotten worse during the mow. After sitting over the Winter, they may have gotten "more rotten".
I'm frugal enough, that I'd kind of hate to have belts sitting around for a couple years while waiting for the old ones to die.
You might just want to keep an eye on them and order new belts when these start throwing "chunks".

Those belts are way too loose. Do you have a manual blade engage or electric pto? If the belts are cracked, replace them. You would think that the guy who fixed your spindle would have done this for you. Call Advance Auto parts. They have a line of belts called Drive Rite made by Dayco that work great on tractors. I just replaced the mower deck belt on my Pro 150 (36" deck) with a 4L78 for $17.00.
Their software is excellent at crossing oem numbers. Is that a Command on that Gravely?

Advance lawn tractor belts are fine if they have the size you need, i use them all the time, and pretty good price too

bushleague,

Yes I have manual blade engage / Kohler Command 14.

Yup, I had a local fella change one spindle. Not a really energetic guy. I'll never go back to him again.

Now I have 2 spindles with grease fittings, and one that is perma-sealed. The one that needs no grease sure won't save me much time. Any thoughts?
