The brand new mower beck belt continues to come off the tractor within a minute of engaging. Is there any way to tighten the tension. I have checked the owners manual but didn't see anything. Thanks in advance...

Hi,
I would guess that you did not reinstall the covers on the deck. The left one especiaa\lly is also a belt guide.

Thanks,
That's all in place with a new tension spring but no luck. I'm at a complete loss.

Hi,
Give that 13 digit number from the left rear fender. I worked for a Deere dealer in the past.
Peace,
Clarke
