Hi Paul It sounds like the belt is worn, stretched, or possibly just two long for your machine. Save yourself a lot of aggrivation by checking your operator manual and getting exactly the right belt for your mower.

You don't say how old your machine is but if it has been mowing for many, many hours, the tensioning spring may need to be replaced. If that is the case you can order a new one at Sears.com

I have a self propelled lawn mower and the the belt that propells the wheels is loose, do I need to replace it or is there a way to tighten the tension.


Cathy, there is a way to adjust belt tension on some models whether it is by the cable or a slotted bracket where the idler wheel is mounted, depends on make and model. If you have your manual check in it for belt adjustment. Could be stretched belt, stretched cable, worn/oil on pulley, seized tensioner, stretched/broken spring on tensioner,etc.

Yth2248 loses speed on slightest grade. new drive belt not helpful


Roy if it is the correct belt and fairly new, check your manual for belt adjustment, if it shows that there is no adjustment the pulleys may be worn out, on a lot of mowers the pulleys are ware items and changed more often to correct slipping issues. The other thing to check is the belt tensioner if equipped, it could be seized, weak or missing spring or it may even be adjustable by cable end being threaded or slotted bolt holes on tensioner arm.
Check the attached links,instruction and guides, Good luck

Replace belts on 917-271821


The deck has an idler pulley that keeps tension on the belt. The idler pulley is mounted on a pivoting bracket, that has a spring which provides the tension. You have to move the bracket so as to take the tension off the belt, thereby allowing you to slip the belt off the other drive pulleys

My craftsman 22" self propelled


Your problem is at other end . Engagement problem is probably due to a loose belt. Make adjustment in that area of mower. GOOD LUCK.

The self-propelled mechanism on my EZ Walk Craftsman does not work. Anyone have a solution?


What you can try is to open the case surrounding the self-propelled drive and make sure that the belt has not either slipped off or has broken. Depending on the model, the case has two or four screws securing it to the frame of the mower. If the belt has slipped off, you can unscrew the tension screw and slip the belt back on and then tighten the tension screw so that there is enough tension on the belt to keep it from slipping off.

If the belt has become broken, you can purchase a new one from Lowes or Home Depot for approximately 15.00. The change out procedure is pretty straight forward and shouldn't take longer than 5-10 minutes.

If the belt is fine (not loose or broken) it could be a gear problem in the drive wheel, in that case you are in a little bit more trouble than simply replacing the belt.

Hope this information helps.

Thanks,

HOW TO ADJUST THE CUTTING BLADE TENSION OF THE MOWER BELT.


There is no adjustment on the Craftsman mower belt tension. The tension is maintained by a spring. If the belt is to loose you either have the wrong belt or something is broken like a mandrel housing that holds the fixed pulleys in place.

Craftsman front wheel self-propelled, push mower: belt keeps slipping off tension pin. Also, the wheels don't rotate as rapidly as when I first bought it last year.


Make sure the pulleys are aligned perfectly straight and replace the old belt with a new one. The pulleys have an allan head set screw you need to loosen to adjust the pulley.
