Thank you for your question.

I am sorry you are having a problem with the tractor. If the mower deck will not engage when you lift the lever, I recommend checking the idler assembly on the deck. Often times the pivot will rust over the winter. To loosen the pivot you will remove the mower deck from the tractor. The instructions for removing the deck are in the manual towards the back. Once you have the deck removed, remove the pivot bolt on the idler. The image below show the bolt that needs to be removed. Then use a wire brush to remove any rust on the pivot and idler. Once you have the idler cleaned look at the cam area of the idler plate. The cam area is what pushes on the brake arms to release the brakes. The cams should be smooth and the rollers on the brake arms should be round without any flat spots. If either looks worn, you should replace them. If you need to order the parts, click on the following link.

If the parts look ok, spray the parts with wd-40 and reassemble the deck. Then move the idler back and forth by hand. If it is moving free, go ahead and reinstall it on the tractor. This usually cures the problem. If you need further assistance, please reply below with more details.

If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website:
