Why wheels want move unless running? - Troy Bilt, Tuffy, Rear - Tine Tiller, 4.0 Tecumseh Engine

remove the key for a few minutes then put it back in it should work unless there is another problem good luck........one more thing u can try put lever in freewheel take key out put lever in drive and put key back should b ok ...cheers

Using an automotive dolly can be risky, If the vehicle is front wheel drive then dolly the front, if it is rear wheel drive then dolly the rear. If it is 4 wheel drive and late model with no neutral shift position dolly the front and remove the rear drive shaft at the rear axle. If the vehicle is older 4 wheel drive with neutral selection for the transfer case then simply shift to neutral and dolly the front axle. Most transmissions whither automatic or manual will be damaged if the engine is not running while the vehicle is in motion.
the engines crankshaft or the transmissions input shaft must turn to lubricate the transmission unless the transmission is automatic and has a rear pump that can lubricate the transmission if the transmissions output shaft is turned in normal rotation for forward direction of travel. This is the only way to to assure there is no damage to the drive train. Be sure to follow all recommended tie down procedures. remember the dolly rotates under the vehicle so one or the other of the wheels must be able to move forward and back to allow for corners. Try to always choose a path that allows forward direction unless you are an expert driver with experience and able to back a farm wagon type axle trailer (like covered wagon) going backward will be a challenge even for someone experienced pulling a bumper pull trailer.
To get the vehicle onto a dolly have some friends help push or use a cable puller to move the vehicle onto the dolly.

Unfortunately if the motor is running but the shredder wheels are not moving you have probably stripped or broken a gear. Most of the time I have had trouble finding new gears for any brand of shredder unless it is a high dollar model. You might be better off buying a new shredder than trying to fix this one.

There has to be a short in one of the wires or one of them are almost completly broken. When you tilt your wheel its probally makeing contack and isint when you dont tilt your steering wheel

Check that the chain is still on both the drivewheel(the part on the motor) and the freewheel (the part on the wheel). If that is connected well, check if the chain moves when you rev it. If the chain moves but the wheel still doesn't move, the freewheel, or gear connected to the wheel, is probably broken and you need to get a new rear wheel. If it doesn't move, the motor is most likely shot, and you're going to need to order a new motor, unless you are confident in taking apart the motor and replacing whatever needs replacing within it.

You might be low on power steering fluid, this could cause a vibration. Another thing could be a faulty engine mount, although it seems unlikely in a car that new, unless it's being driven real hard.

it sounds like the belt to turn the wheel broke

Some Troy Bilt Tillers were designed with a manual "free-wheel". If yours is a Tuffy (and maybe a Junior), you have to pull pins out of the wheels to move the tiller without starting it. The larger tillers, Pony's and Horses, had a lever to shift to release the wheels.

The differentials should be disengaged or you going to do damage. They should only be locked in when moving at low speeds.

4 wheel drive vehicles are desigined to run with equal size tyres front and back, if not severe stress is placed on the drivetrain, The transmission will most likely need overhaul, biut do not be surprised if you have transfer box faults and diff faults as well.
