The wheels lock up when i pull my lawnmower backwards

I have a 4 year old honda 3 speed lawn mower and recently when i tryed to pull it backwards the wheels stay locked....i have cleaned thoroughly the underside of the mower and removed and greased the shafts that hold the wheels on....it appears to be a problem with the gearbox...
is it the gearbox or clutch?
if so how much to repair?

If you hold the clutch down to shift the gears after you release it if it doesn't move in reverse you have a gearbox problem and the easiest way would be to take it to a shop to have them fix it, it may not be too cheap but it is cheaper than getting the parts taking it apart and not being able to put it back together right. if you try to fix it yourself you could really mess it up and then it would end up costing you more than it would have to have just taken to the shop to start with.

The right rear wheel intermittently locks up on my lawnmower when going forward stopping forward movement temporarily, until I move it backwards to "unlock" it. Any ideas?


There is an excellent 3 part video that may help you to fix this problem. Please see the 2nd and 3rd videos:
https://youtu.be/Vk_tpjKlbjM
https://youtu.be/DdiewLxTQDc
Things you can try:
(1) Remove casing over rear wheel drive assembly and perform a test run to assure all parts are moving as expected
(2) Lubricate the shafts with lightweight motor oil where the shaft penetrates into the gear box of each wheel
(3) Remove each rear wheel, inspect gears for damage and free movement. Grease up each drive gear and the shaft.
(4) Inspect gears on each wheel for damage.
(5) If none of the above fixes the problem, try swapping out the front wheels to the rear wheels provided the front wheels can accommodate the gearing on the rear wheels
(6) If this doesn't work try replacing the small gear assembly on the right rear wheel
These steps are illustrated in the videos.
Good luck and hope this helps.

Drive wheels lock up when pull mower back


Here is what's going on. I cleaned the wheel "dogs" or whatever you call them multiple times. This DID NOT fix the problem. Look at the cable that engages the forward movement (self-propel function). If there is any slack in the cable near the handle, then there is retained tension at the transaxle. Not enough to move the mower forward, but enough to keep the wheel from freely rotating backwards. I tipped my HRX217 on it's side and located where this cable engages the drive box. Lubricate the heck out of it and coerce it to move with needle nose pliers. After thorough cleaning and lubricating both ends of the cable, I am now able to move the mower backwards without lock-up. Hope this helps someone, as I found nowhere on the internet that this is what REALLY fixes this

My ground speed is very slow can i adjust the travel pedal on my troy built 22 hp 46 in hydro lawn mower


I have the same machine, [pull plug wire for safety] tip machine on it's side, next remove blade, now remove all the plastic shields that are above blade right to the deck bottom. You wont believe the grass build up around blade shaft. On this machine as you select your speed the pulley travels on shaft, but with the grass build up the pulley can't move. I've done mine twice now in the last 4 years. You'll need around 3 hours, good luck it's not that bad.

Craftsman mower #247.887760 rear drive. rear wheels lock-up when you try to pull mower backwards


The rear wheels are locked to the drive train. To pull or push the mower, you must pull out the release probably at the back of the mower, near the transmission.

The rear wheels will not turn in reverse at all. I


Rear wheel drives like this have pinion gears with rachet pawls that allow them to go backwards freely while locking when the transmission drives them.

You need to take off your rear wheels and carefully remove the pawls. They look like little squareish metal shaft keys with springs under them. You should notice that the keys or pawls are covered in what looks like grease.....which is actually worm metal from the pinion gear and oil mixed together to form this pastey greasey substance. Clean all that stuff off and lightly oil *( light oil...3 in 1 kind of oil) and reassemble.

You should hear the nice clean clicking of the rachet pawls as you roll backwards again!

Good luck and be careful!

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.

Trouble starting my old Toro mower


This is a 20 year old mower. Has it been used on a regular basis over recent years? Try spraying some carburetor cleaner down the carb throat to see if it fires up. If it's been sitting for awhile, the carb may need to be cleaned out.

Honda Harmony mower, self propelled hydrostatic, wheels lock up when pulled backward. Going forward no problem.


If i remember correctly, under each drive wheel, there is a small gear, and under each gear there is a small metal rod that is what the transmission uses to propel the mower...it sounds like the rods either have dirt on them or they are just stuck and can not move to allow you to pull it backwards

Wheels do not freely roll backwards


SOUNDS LIKE THE PINONS ARE ON BACKWARDS. THE KEY SHOULD SLIDE OFF THE PINIONS WHEN PULLED BACK AND LOCK WHEN ENGAGED. YOU HAVE THE OPPOSITE PROBLEM OR ITS BACKWARDS!
