1772 mower belt slips
 

I was wondering if anyone else has issues with mower belt slipping under a medium load? I am getting ready for leaf mulching and have had problems in the past with belt slipping/ squealing.

I just installed a new drive belt and it still slips. (at least this is the belt I'm guessing is the culprit) Here is a pic of the pulley in question.(top pulley)... To me it looks like the belt sets very low in the driven pulley. Notice how the lower belt (blade belt) sets high in the sheaves....

Would a new pulley fix this? What about wider belt?
Thoughts?

.

Yes, that looks wrong. What deck and belt is that?

That pulley looks bad almost split open unless it's just the pic making it look that way

The deck looks like a 44C/50C deck. IF...that is the case, that belt is too small as far as width. You need a 5/8" wide belt.

The deck is a 50", Manual cover shows model #359, but dad had written in by hand model 50A?

I got the replacement belt at NAPA. Gave them the Cub #954-3006 to cross reference.

They gave me a Bladerunner 6714BR. Just googled that belts specs and it shows 1/2" wide by 93.25" length. Guess trade in time at NAPA!

Thanks for the help!

190-359-100 IS a 50C mower deck and requires a 5/8" wide belt.

The correct belt is: 954-3006 BELT-V, 21/32 X 93

New , wider belt is on the way. Thanks for the help!
