Slow snapper quantum xrm

michele3918August 25, 2013

Hello everyone,
I have a slow Snapper quantum xrm 6.5 hp, it's frustrating because I can't seem to figure out the cause.

Perhaps some of you can shed some light on the subject and help me figure this out.
I've spent many week ends on this challenging project.

The lawn mower moves too slow even at the highest gear selection. (6 positions)
I use to have to run behind it at that gear selection.
(Yes, I did that on a few occasions)
Basically, it moves as if it was set on the 3nd gear position when it was operating normally.

Troubleshooting steps:
1 Replace driven disc spring-Yes
2 Replace driven disc-Yes
3 Replace all belts-Yes
4 Replace clutch cable upper spring-Yes

Other failed attempts:
I glued some 60 grid sand paper on a stick and ran it on the drive disc with the mower running. I did that to clean the drive disc and to give it some texture for better grip.

I also tried to select a lower gear just to position driven disc on another surface area.

Thats all I can think of right at the moment.
Hope to get some tips soon.

Good week end.


Thank you for reporting this comment. Undo

I have the same exact problem with a 21" Snapper. I was about to go to a dealer and pick up a new driven disc and belts, but maybe that won't help, if you tried it and it didn't work. Did you ever fix the problem? I can't believe that it would be something simple, like worn tires or whatever.
