60"MMM Belt Tension

60\"MMM Belt Tension

Is the belt tension adjustable? I detected a noise this weekend and found that it was the belt "wobbling". My mower may have 4 hours of mowing time on it and I was wondering about any adjustments. The book says that to winterize your mower by relaxing the belt. I saw nothing about tightening or making adjustments.
Any input is appreciated.

Isn't there a belt tensioner idler pulley on a spring down there? Hence no need to tighten it...it's always under load. Kinda like what you'd see on some Ford Mustangs...gonna go check mine now.

Frank,
Yes there is the spring. I took-off the guards and watched (carefully) as I started the PTO. When I had close to maximum RPM's there was a lot of wobbling in the belt. The belt is rubbing on the bolt on the left side just behind the left pulley. It is probably normal, I just had not noticed it before. But why does the book say to relax the belt tension when we winterize. How is this done? Releasing the spring?
Hmmmmm..................

Re: 60\"MMM Belt Tension

I saw the spring/idler pulley when I was hosing mine off after mowing again for a while today. As far as winterizing, Kubota is either worried about the belt stretching or the spring weakening or something else, I dunno. Since I live in Florida, there isn't a need to winterize anything...the grass always grows down here. Pulling that pulley back a tad and slipping the belt off of it would probably do the trick, although I have never done it personally...just relating from the times I have done it on a Ford (car).

I think the next time I have to hose off down there I'll take one of the covers off and engage the PTO to see if I get any belt wobble. It sounds nice and tight down there, but will check it again when I mow the yard in a few days. A belt rubbing against anything can't be good for it.

Frank-what is a "bota-cam"?
AND how did you put the tractor in as a signature?
Thanks for your reply as to belt tension.

Billy,
Bota-cam is something I am going to add to my Bota when I get a little bit better at controlling her FEL and Boxblade. Basically it'll be a Webcam from the tractor to my wireless network, but think it'll be video clips more than anything of a B2910 in action. Guess it's just something fun to do, but have to wait for my canopy 1st.
As far as adding a signature, there's a thread that describes it titled "Signature" or "signatures"...something like that. Do a search for it and it'll show you how. You do have to 1st draw yourself a tractor or find a picture of something to use, then convert it to .jpg with Frontpage or the like. Takes a little time, but it does work.
