60 inch belly mower concern

60 inch mid mount belt concern

I purchased a new bx23S with a 60 inch belly mower this past summer. A big concern of mine is the sloppiness of the belt. It slaps around so much it hits itself and the bolts that attach the belt shields. I smell the belt while mowing and black residue collects on the deck. Its been checked and adjusted by the dealer and by service reps and all reach the same conclusion; that it measures up to factory specifications and that's just the way they all are. Has anyone else observed this and should I be concerned?

I have a 60" driveover deck on my 2380 and it doesn't do anything like what you are describing. Only time I've ever smelled a burnt belt is right before I had one snap on a Cubcadet I had a decade ago.

Sounds like you have the wrong belt, or the belt with the correct number is mis-marked. Might take the belt off and measure it, then compare it to a new one at the dealer.

No, D2Cat, A dealer wouldn't do that.
He's right, that's what it sounds like.

Have you checked the belt tension spring and pulley, for damage or stretch?

 

[rjcorazza]

There are a lot of things to check when diagnosing belt problems. Some that come to mind are:
Confirm (measure) belt
Confirm all pulleys are free and not damaged (check with belt off)
Check for debris jammed in pulley (rare, but happens)
Check tensioning arm for free movement and good tension

My walk behind belt was slapping around several years ago. Everything looked good with the belt on, and rotated smoothly with good tension from the tensioner. Further inspection with the belt off revealed that the tensioning pulley halves (rivited together) were coming apart.

Something is wrong.

If the belt is correct and undamaged and the idler and spring are as designed, perhaps, the belt has broken chords and/or a pulley is bent or otherwise damaged. A belt with broken chords will vibrate badly even if it appears visually to be OK.

Make sure the belt is running in the correct position. It's possible to have it on the wrong side of a pulley and yet somewhat "fit", but it won't perform correctly.

My neighbor had one vibrating really bad. There was a sweet gum ball stuck in one of the pullies.

Had something very similar happen on my ZT. A half chewed up pine cone got wedged in the pulley. It was very hard to see. I could tell which pulley was making the racket but when I pulled the belt off it was solid and smooth as can be. I had the dang thing almost off the mower housing for further inspection before I finally noticed it.

My 60 mmm does none of that... Itll be three years old in May and Ive only greased the zerks every 10-15 hours.

I admittedly abuse it. Ill raise it all the up and use it as a bush hog in certain parts of my property where its tall heavy grass. The golden rod gets chopped by the rotary cutter, Im not that crazy...

Good advice. Some thing is wrong . I'm on my second BX with 60" deck and no problem your having.

I bought a bx2680 in may & the mower belt slaps quite violently making a fair amount of noise. Is this normal

Does your belt run smootf or slaps back & forth a lot

 

[jav1948]

Dealer says there is no belt tensioning adjustment on my new 2021 bx2680 mower/ tractor. This is not the drive over deck. Does that sound correct. I get of belt slapping & noise from the mower & i think the noise is the belt.

It slaps back & forth a lot
