The old belt broke & replaced it with the exact one from JD. When the blades are disengaged & you shut the engine off the blade pulleys still spin & eventually stop. Blades are fairly new & there’s no play or slop with the deck pulleys. Doesn’t seem to be a way to tighten up the belt tension. Anyone else have this happen before.

Make sure the idler arm return spring is in place as help to engage the spindle pulleys brakes when the PTO is disengaged. Also check brake assemblies themselves as they can be binding up due to dirt/rust.

The deck belt is auto tension-ed via the PTO cable spring.

You must of missed something in the belt routing or a pulley has fallen off.

According to pictures I checked, this has a manual lever and cable to engage the deck operation. The spindle pullies have a blade brake for each one. These brakes do wear with age, and they are only there to slow the blades to a stop when the deck is disengaged. The brakes do not firmly hold the pullies at a fixed stop.

Thanks for the reply & suggestion. I’ll go over it again & the belt routing.
