Self Propel Belt, how to replace with the new one

Yes it is the transmission. A Mower shop will charge you about $225 to fix.. I order parts online and fixed mine for $90. Transmission consist of 3 gears which turns the rear wheels to self-propel.

i would guess that the belt is'nt tight enough when engaged. when you press the drive bar on the handle it should make the belt really tight if not it will need replaced. sometimes the gears in the wheels will mess up. there are videos on you tube that describe that and also the belt.

Remove the plastic cover for the drive belt. Replace the belt.

If it's where i think it is you have to disconnect the axel rod off of one side and put the belt around the shaft from there.

put belt dressing on the belt

You probably answered your own question, the belt is the first thing i would check

Unfortunately, you cannot adjust it. If you have an extra space to move it lower than it was on the handle you can do that. You might have to get a new cable. Or the belt may need to be replaced. Do you hear a grinding noise when you try to engage the self propel? If so the transmission may have gone out. The most common problem is that the belt has jumped off from where it needs to be and it is no longer turning. To check to see if the belt is off, you will need to put the mower on its' side, the side with the oil level check is the correct one. You will need to loosen the cover over the drive belt. This is done by loosening one or two bolts that hold it in place.The bolts should have 3/8 hex heads. You may have to maneuver the cover a bit to see if the belt is in place. If the belt has jumped above the pulley for the self propel then you will have to install a new belt.

Check for the belt under the cover that drives the mower. If you remove the belt, you will have things the way you prefer.

Your self-propel is probably belt driven. Belts can make an awfully lot of noise when unhappy. Possible it has rolled over and is running on the wrong side of the belt or is worn and just needs replaced. Hope this helps.,

hello
check the drive cable as not come adrift or broken
you can usually adjust the tension on top of the drive cable
also check drive belt is on the two pulleys
