    If the cable is over-tightened it will lock up when going backwards. Does the mower try to pull itself when it is first started? If you pick up the back end while the engine is running (only use the handles... do NOT try to lift up on the deck with the blade moving, this can cut off your fingers) are the wheels turning with out you engaging the self propel?

SOURCE: Honda Harmony mower, self propelled hydrostatic,

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

SOURCE: the wheels lock up when i pull my lawnmower backwards

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.

4 wheel drive won't engage


Which do you have ?
Transfer Case - NVG 236 (Two Speed Automatic)
Transfer Case - NVG 233-NP1 (Two Speed Selectable)
The NV236 transfer case is an automatic transfer case with three drive ranges. Shifting from rear wheel drive to four wheel drive is done automatically when the transfer case shift control module receives wheel rotating slip information from the speed sensors. The transfer case shift control module then engages the transfer case motor/encoder to position the transfer case from rear to four wheel drive. When the transfer case shift control module receives information that the wheel rotation is the same on both axles, the transfer case shift control module sends position information to the motor/encoder to put the transfer case back into rear wheel drive. The three drive ranges are 2HI, 4HI, and 4LO. The 2HI position is for normal driving with the rear wheels pushing the vehicle. The 4HI, position is for driving through sand, snow, mud, gravel, or heavy rain at normal or slightly below normal speeds. The 4HI engages the front axle to allow for four wheel drive. The front axle is pulling the vehicle, and the rear axle is pushing the vehicle. The 4LO range is used for off road driving, heavy snow, deep mud, or shallow fording. The 4LO is similar to the 4HI except that the gearing in the transfer case is set for low speed and high torque. The NV236 is manufactured at Syracuse New York by New Venture Gear a division of New Process Gear for General Motors.

Adjust chain on a womans city ii 3 speed internal gear rear wheel


Loosen the rear wheel nuts. Move the axle forward to loosen or backward to tighten, keeping the tire spaced equally between frame and brake. Adjust so that chain is in that "sweet spot" between binding because it's too tight and slapping against the chain guard because it's too loose.

Some models have screws in the frame at the rear axle that make this job easier. Note that it's likely that you'll need to adjust the gear shift cable after moving the axle. Good luck, and happy riding!

2003 mercury mountaineer brakes locking up abs light is on


Possibly has a bad wheel speed sensor or has a problem with the ABS control module and/or pump. Need to have the ABS codes pulled by a service center. Also, some auto parts stores can pull codes and may be able to pull ABS codes.

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!

Speedodomoter will not move and brake light, abs and service will not turn off. had codes pulled and they show speed sensor circuit condition, detected a fault in speed sensor circuit, poor electrical...


1. Check the resistance of the rear wheel speed sensor. It should be 1200-2500 ohms.

2. If OK, check the wiring between the rear wheel speed sensor and the Controller Anti-lock Brakes (CAB

sometimes this sensor is on the rear of the transmission or the rear differential.

Suddenly stopped then could not pull mower backwards because rear wheels would only go forwards, and mower would no longer start


Sounds like your mower has a safety mechanism that has locked up. On your push handle is a bar that must be pulled back in order to pull start cord, it has a cable that goes to the safety brake, check the cable to the safety brake on the flywheel, it may be broke. If it isn't in the safety brake itself, try spraying the cable with WD-40 as this may free it up. Or the cable may need replacing from wear. To check this pull back on the handle and watch the on the side of the engine where this cable attaches, if it is moving on the side of the engine then this cable won't be the problem. In this case it most likely will be the safety brake itself that's the problem. Do not remove the safety brake if under warranty as this will void your warranty.

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!

TCS/SLIP & Check Engine Light Warning


TCS is Traction Control System,and all TCS's are controlled though the Anti Lock Braking (ABS) system.Here's how it works:Each wheel,or in some cases,only the drive wheels have a speed sensor mounted near the hub or axle,and sends a speed signal to the PCM (Powertrain Control Module).The PCM monitors wheel speed continuously,and if it sees a speed out of the ordinary,say for example the right rear tire is spinning and traveling at a much higher speed than the left rear,the PCM will pulse the brakes through the ABS system on the right rear to slow down the right rear so that the left and right wheel speeds match up,this is how the traction control works.So,if you have a TCS problem,the PCM will see this and set a Dignostic Trouble Code (DTC).You need to pull the DTC's out of the system with a scan tool,diagnose and repair the DTC's.It could likely be something as simple as a malfunctioning wheel speed sensor,but you won't know until the codes are pulled out,as this will point in the general direction.Good luck.
