Toro 20016 self propel

Toro 20016 self propelled walk behind when the wheels are engaged it moves, when the wheels are not engaged, the wheels look up.
What should I do to fix the problem

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.

The self propel cable needs to be adjusted. This can be done with a 7/16 wrench. loosen the nut that holds the self propel cable in place. You may need to pry this open with a screwdriver. Don't overdo it or you could break the plastic. Once the cable is loose pull it toward the mower deck, once the slack is out of the cable press the self propel handle in about a half of an inch. This should be close to what it was from the factory. Then re tighten the nut. And check the self propel to make sure it is engaging properly. If you hear a grinding noise when trying to engage the transmission then you will need a new transmission. Depending on if it is a front or rear self propel the part alone is either $60-$75 retail. Most repair shops will charge an hour to do this repair. I hope this answers your question.

Remove the left wheel and check the gears inside the wheel and the drive sheft. They might be worn or sheared and need renewing or maybe they just need oiling. Spray them with WD 40.

You might have a broken belt to the self propelled or a broken spring or whatever engages the self propel. Take off the cover and see if anything is broken or missing. Have someone engage the self propel while you are watching and see what is going on.

It may just be a matter of adjusting the cable. Sometimes they dont get them adjusted just right from the factory,heres what you do. Locate the plastic shroud in front of the push mower that covers the drive unit.Determine which screwdriver or torx bit is needed to remove shroud and remove it. After removal you will see a pulley with belt around it, as you pull the handle back to engage self propel you should see the pulley move into the belt to put tension on the belt. You can do this with it running to see if enough tension is being put on the belt,if not, locate the cable end where the small bracket holds the cable in place. Loosen the cable bracket and move cable until you have correct tension again,hope this helps.

You dont adjust the belt,you adjust the cable that moves the pulley into the belt. There will be a small single bracket close to the engine side of the mower that holds the cable in place. Simply loosen bracket and move cable until pulley contacts belt enough to engage self propel.

Regularly check the wheel-drive belt on a self-propelled mower for wear and tightness .... "Affected engines may run rough, stall or bog down under load,"

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.,

Either the cable that engages it is broke or the belt that drives it is broke.
