SOURCE: Craftsman Transmission problem

Some of these tractors have a friction wheel that is driven off of a flat wheel on the bottom of the engine drive shaft. The rubber ring on this friction wheel could be worn out, or it could be out of adjustment.

SOURCE: I have a 20 hp craftsman lawn( hydro gear

It sounds like the oil in transaxle is degraded.The transaxle is supposed to be a sealed unit requiring no service but over time the oil will get dirty enough to cause problems like you are describing.Remove the back hitch plate and look at the transaxle it will have a rubber vent hose or a 1/4 alllen wrench fitting on top. You will need to purchase a battery suction bulb from sears automotive and use it to remove as much oil from transaxle as possible. Warm the transaxle up first by running it around,then suction the oil out.Refill with a good synthetic motor oil 15w-50 or 20w-50 like Amsoil or Mobil 1.Do not use transmission fluid or hydraulic fluid. When adding the new oil back fill it to within 1.5 in from the top,be sure to allow this amount of air space in top of transaxle for expansion.

SOURCE: Was mowing when it just stopped going forward. It

Under the mower below the seat of the rider, at the rear of the tractor, look up and you will find the transmission there. There is a belt that runs on the pulley under there, and this belt can slip off when it gets worn or stretched. Sort of a tough spot to get to but, that is most probably cause.

Let me know,
Chip

I HAVE A 1994 MTD 18HP BRIGGS WITH MOD #144Q828H118, WHILE I WAS MOWING THE CLUTCH WOULD NOT RELEASE AND THE GEAR SHIFT WILL NOT GO INTO THE LOWER GEARS. WHAT HAPPENED?


The tractor has a variable speed pulley for the 1-6 gears. You will want to check the top pulley on the shaft that is in the center of your tractor between the engine and transaxle. you may have broke the spring or adjuster.

While mowing it started 'jerking' going forward (John Deere RX75)


if this is a MTD rider, (troybilt, yard man, yardmachine,. bolens, cub, etc) the transmission is likely a single gear forward and reverse with a variable speed pulley mechanism with two transmission belts, these trans are prone to failures of the gear clutch which is a dog style clutch with some small teeth that engage the gear plates, these teeth can wear off on one side resulting in the popping or chattering while retaining full functionality for the other direction, this is the gear set inside the transaxle and is usually an indicator of significant wear inside the axle housing itself, usually entire transaxle replacement is the most common and effective repair solution.

Lawn tractor forward movement problem


Check the adjustment from the lever to the transaxle, if the linkage is ok the transaxle may be suffering from age and has leaking internal seals.

Transaxle locked in gear won't roll freely in neutral


Sounds like the pins in your brake caliper have gotten dirty and/or rusty and are not releasing all the way. When I had my shop, we found a lot of these and I or my mechanics pulled and cleaned them then took a drill 1/64th larger than the pin and ran it through the holes in the caliper, NO MORE PROBLEMS!
Check your tire pressures, too, if they are low it will be difficult to roll.

Cratsman lt2000 lawn tractor will start but will not move forward or backward. I tried changing the drive belt, but that didn't work.


Is the transaxle pulley turning? If so have you removed the rear wheel recently and possibly lost the square key that fits on the axle?check those two items first.If ok it probably has a broken gear or shift key in transaxle.

Will not go into gear


a hydro uses a foot pedal on the right side , you push forward to go forward or rock the pedal rearward to go in reverse - a regular transmission has a shifter usually between your legs for reverse 1st 2nd or 3rd gear - you also said the blades wont engage . are they electric ( with a switch ) or do you manually move a lever .
