Idler pulley worn out

Actually the repair was quite an easy one, once I figured out how to get the nut off the pulley. The way MTD made the tractor was really dumb. They put a nut on the idler pulley where you can\'t get a wrench on. There\'s about maybe 1/4\" gap between the plate the idler bolt goes through and the chassis plus the fact you need a long, and I mean long, open end 9/16 wrench to place on the nut.
I got the nut off and to save me the trouble the next time, I drilled a pilot hole from underneath where the bolt goes through then cut a 1\" hole in the chassis on top to get to the nut. I replaced the pulley and put a hole plug in the 1\" hole I drilled. After that, no problem and the pulley works like a charm.

No Brakes. When the mower was in Fwd or reverse it would move and could not be stopped. The idler pulley had also seized and was binding up the drive belt.

I replaced the drive belt for the mower and found that the brakes were not functioning and the idler pulley for the drive belt had failed as well..The brake pads had to be replaced and once the idler pulley was replaced and adjusted for the new drive belt I was able to adjust the brakes. For easier access I had to remove the deck and jack up the mower and put it on jack stands. I could have leaned the mower on its side to do the job but decided to use the jacks instead. I did it this way so that I could engage the drive and make the wheels turn while the mower was on the jack stands in order to adjust the brakes. I also removed the right side tire in order to access the brake assembly. My mower is a Troy Bilt Bronco made at about 2005.

1. I took off what was left of the old pulley (mostly plastic) and replaced it with the new all-metal pulley from e-Replacement Parts.
2. Then, I mounted the new upper drive belt.
3. From the time I placed my order on-line it only took two days for e-Replacement Parts to ship the new parts from Utah to me in Virginia and th e next morning I quickly made the repair and had my lawn tractor running again.,
