Yardman snowblower won't self-propel

Make sure the belt is right if so u may have a bad transmission.

Most self propelled snow blowers are driven by a sliding rubber disc. That disc is driven by a belt from the engine. The belt can wear and needs adjustment. The handle that you hold has an adjustment for the tensioner pulley and spring assembly used to engage the belt. The belt can also be worn to the point of needing to be replaced.

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.

Hello,

You didn't specify the make or model of your mower, but generically speaking for self-propelled walk-behind mowers, the drive belt or the front wheel gears can wear out after several years of use. The drive belt could also be loose or off the pulley. The belt and the front wheels can usually be replaced.

You can remove the drive pulley cover and see if the belt is off.

The other components that make up the drive system are the gearbox and the engagement cable. Sometimes the cable can get get out of adjustment or come loose.

The drive pulley can be replaced, however I would only recommend being service by a vac shop professional who has experience with the Hoover Self Propelled models.

If you have the smell of rubber burning the belt isn't gripping. Make sure that there isn't anything stopping the wheels turning like old grass or even a piece of twig. If their clear try adjusting the tension on the drive pully.

Hello,

Which belt? You are referring to the auger drive right? The self propell uses a friction disc drive.

The auger drive has two belts, and in order to replace them you need to seperate the auger from the engine (split) the blower.

Happy days.

remove the front black plastic plate that is stamped self propelled and replace the wheel drive belt that attaches the engine pulley (above blade) to the transmission pulley (found under the cover). When you buy the belts, pick up two or three as I seem to go through a couple per season. Hopes this helps

Typically self-propelled mowers are propelled using the front wheels, which only turn forward. Pulling the mower back while the front wheels are turning will damage the drive gears. It's best to raise the front wheels slightly off the ground before pulling back.

If you take the wheels off and remove the belt from the small pulley on the the front axle underneath the pulley you should see a small transmission. You usually can split this unit in half . You will see two gears and sometimes one plastic and one metal. The plastic one is usually the culprit. Hope this will help you out. Donnyb60
