How do you remove the gears on a front wheel self propelled troy bilt push mower?

Most of the self propelled mowers have a pin in them. you need to use a pin punch and a hammer to knock it through. The gears will come off then. Post a picture if need more info.

most have small leaf springs that let it toggle back and forward, if they brake can cause this problem. Then it may just need the wheels removed, clean the parts and lubed

Drive cable or drive belt could have broken

Cable could be stretched belt could be worn or old, if it has a gear box maybe it slipped a gear or lost some teeth. Do some investigation, Good Luck

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

There is probably a cover on the front part of the mower that goes to the front wheels. remove the cover and you should have access to the belt. Carefully remove the belt (don't pinch your fingers) push it back towards the motor. You might have to remove the blade. Place new belt in the pulley on the engine shaft then to the pulley up front. Carefully start the belt on the front pulley and slowly turn it onto the pulley.

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.

ya the trans is trying to go out and thay look up thay do that all the time

It sounds like you need a new belt for the front wheels.
