Question moved to John Deere D110.

Try the 5 minute fix, but your sounds like the hydrostatic transmission.

A lot of mowers have a safety feature built into them that don't don't allow reverse mowing, there is a sensor switch that cuts the motors when depressed. you can however override this safety feature by removing one of the wires off the reverse pedal depress switch, but do so only if you are a competent confident user of the machine. And remember to reconnect the wire if there will be other users.

Does the bolt tighten up tight when you put it on, if so try putting some thread locker on it. If not then you have to replace the shaft

Get yourself a rattle gun connect it to an air compressor with the right
size socket hold the gun on reverse it should remove the bolts.

As you are looking at the blade and bolt from under the mower, if the blade is rotating counterclockwise, then the blade bolt is standard threaded and will turn counterclockwise to loosen. If the blade is turning clockwise, then the bolt is left hand threaded and will turn clockwise to loosen. John Deere produces mower decks with both setups.
Good luck!

The bolts that hold the blad on are left hand thread.

Good luck and please rate 4 thumbs up for the free answer.

Always unscrew the bolt in the same direction of blade travel.If the blade travels clockwise,loosen bolt by going clockwise.

That is a cap screw you are talking about. The size of it is 7/16" X 1-3/4". The John Deere part # is 19H2563, but I am sure you can just get one at the local hardware store. I could not find out for sure, but on most blades they use a fine-thread bolt/screw. If you can tell the difference, check before you buy, or just buy both and see which one threads in easily. Hope all this helps.
