I have a model 556 troy bilt 21" self propel mower. The control cable broke at the front end under the plastic cover. I have removed the cover and can feed the cable back through the sleeving but do not know where to attach it. Can someone help me? Do I need to replace the entire cable assy including the sleeving?

SOURCE: front wheels lock up when pull mower backwards

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.

SOURCE: troy bilt mower self propelled 21". Belt has come off

Take the three screws out of the belt cover. One screw in behind each back wheel. The other is under the mower near the shaft to blade. Remove the tension spring off the transmission. Then remove blade and the cover comes off. You then can put the belt back on. Sounds like fun don't it!

You need to remove a pulley to put the new belt on.

SOURCE: where is the oil plug located on a troy bilt mower?

Tilt it over so the oil cap is on the bottom...it'll rest on the handle and hang there...put a container under the oil fill pipe...something shallow like a glad sandwich container works perfect...get a paper towel, and reach under an unscrew the cap...all the oil runs out into the container...it'll fit !!

Wipe the dipstick off clean, and put it aside...take this time to look at your blade on the other side...it "should look" similar to wood chisel at the last 5 inches of the blade on both ends followed by a wing under it...BTW: their $12 bucks new...and worth it !!

Go back and look at the container and be sure the oil is finished draining...take the lid for the container and snap it on and move it out of the way (no body likes an oil spill)...wipe off the oil fill spout, and re-fill...takes about a half a quart, so don't over fill it !!!

your done...

SOURCE: Lawn mower sounds like it is running fast and vibrating.

Sounds like a bent shaft, or bent blade.
Also sounds like the part that holds the blade to the shaft is sheared, and allowing the motor to run faster than it would if it is turning the blade properly.
Hope this helped,
Please rate me
