mounting mower deck on craftsman mower

When mounting the mower deck on a craftsman riding mower model #917.256531 the right side of the mower deck hits the right rear wheel. Also have been having a problem with the mower blades slowing down when getting in high grass and not cutting the grass, prior to taking the mower deck off.

Now that spring is approaching its time to get this Mower fix so you can get a better cut for your grass. A suggestion I have is to visit Sears Home Services website to set service with a Sears technician. I have attached the link below. Hope this helps!

Thank you for your question.

I am sorry you are having a problem with the tractor. Usually when the deck hits the rear tire it is because the deck adjustment. If the front of the deck is too low, the back of the deck will hit. I have added an image below that shows how to adjust the deck. If the deck still hits the rear wheels, I suspect the problem is worn deck mounts.

As for the mower stopping when in tall grass I suspect the problem is either a worn belt or the idler arm is binding. First, remove the deck from the tractor. Then move the idler back and forth to make sure it is free. If it seems tight, you can soak the pivot with WD-40. Once you have confirmed the idler is free check the condition of the belt. If it looks worn, go ahead and replace it. Here is a link to order any parts you need.
