Question about Husqvarna Garden

Husqvarna, GTH2454T Hydrostatic power loss.

Husqvarna, GTH2454T, three years old. Hydrostatic, lever operated transmission. I have recently begun to have problems with the mower not wanting to pull itself up grades it never even strained with before. I purged the transmission according to the instructions for a new mower, and it seemed to work better for twenty minutes. Any help would be greatly appreciated.

If it's like mine the transmission is sealed and cannot be serviced. A local repair shop told me most likely the problem isn't with the transmission but rather the engine pulley is worn. He said if sand or debris gets between the belt and the pulley which has a definite "V" shape to it that it will wear down to a "U" shape. Now mine has a foot clutch on the left side so he had me pull back on the pedal which manually tightens the belt. I did this and it works like a champ. This winter I'll change the pulley.

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.

Maintanance - How to purge Hydraulic drive system Published 01/13/2010 11:56 AM ' Updated 06/02/2015 02:52 PM
How do I purge the hydraulic system?
Hydrostatic transmissions use oil, under pressure, to provide movement for the tractor. The fluid is pressurized with a pump inside the transmission. If any air is in the fluid, the pump will try to pressurize air. This condition is known as cavitation, and is detrimental to the pump since it allows the pump top operate dry. When the pump cavitates it is not pressurizing any fluid, so the transmission is not able to provide the movement needed.
If your mower is new, or has been stored for a long period (longer than 2 months) the transmission needs to be purged before use. Also, if you experience loss of drive, or slower response, then the transmission should be purged first.
The following procedure will remove trapped air inside the transmission(s).
IMPORTANT: SHOULD YOUR TRANSMISSION REQUIRE REMOVAL FOR SERVICE OR REPLACEMENT, IT SHOULD BE PURGED AFTER REINSTALLATION BEFORE OPERATING THE TRACTOR.
Step 1- Place the rear of the mower safely onto jackstands on a level surface with engine off and parking brake set.

Step 2- Disengage transmission by placing freewheel control, located at the back of the frame, in the freewheeling position.

2a- Mowers with seperate pumps and wheel motors the freewheel is activated by turnign the bypass valves, one on each pump, two full turns.
The oil resevoir needs to be filled to the specifications listed in the owners manual before starting the purge procedure.
Step 3- Sitting in the operators seat(riders), start engine. After the engine is running, move throttle control to slow position. With motion control levers in neutral (N) position, slowly disengage clutch/brake pedal.
Step 4-Move motion control levers to full forward position and hold for five (5) seconds. Move levers to full reverse position and hold for five (5) seconds. Repeat this procedure three (3) times.

NOTE: During this procedure there may be some movement of the drive wheels, but they are not under load. The air is being removed from hydraulic drive system.

Step 5-Move motion control levers to neutral (N) position. Shutoff engine and set parking brake. Check and add oil as needed for units with an oil resevoir.

Step 6-Engage transmission by placing freewheel control into driving position, or by closing the bypass valves on the pumps.
Step 7-Sitting in the operators seat, start engine. After the engine is running, move throttle control to full speed. With motion control levers in neutral (N) position, slowly disengage clutch/brake pedal.

Step 8-Slowly move motion control levers forward, after the tractor moves approximately five (5) feet, slowly move motion control levers to reverse position.
After the mower moves approximately five (5) feet return the motion control levers to the neutral (N) position. Repeat this procedure with the motion control levers three (3) times.

Step 9-Your mower is now purged and now ready for normal operation.For further information or assistance, we recommend contacting your lo

Transmission loses power when pulling disk changed hydraulic filter motor was rebuilt year ago why im i lose power in transmission? ?


If this is a hydrostatic transmission on a lawnmower type garden tractor some power loss is expected. That just the nature of hydrostatic transmissions.

Severe slippage may not be the transmission itself but would the drive belt. These wear out over time along with the idler pulleys; especially the plastic v-idler pulleys. As the idler pulleys wear out is the same as lengthening the drive belt to a point where it slips. Even a new belt will if these pulleys are worn enough.

New tractor power loss on a grade, deos not develop full speed


Hello Joe

If you have an automatic or hydrostatic transmission then you have a lemon, which means once the oil heats up in your transmission it thins out and clutchs and swash plate have no grip on the drive system which is hydraulic pressure needed to hold on the shaft and axles this happens all inside the transmission you cant see it but you can tell when going up slight hills and when you have the blades engaged it crawls like a turtle get you warranty out Joe..... dont touch anything that may void your warranty..... just call service department they will send service man out to your home even after that keep a good eye on your tractor since its still under waranty for further problems.

Joe your 20 year old craftsman had a better built ****** by sears and you probably had a 6 speed or five speed even hydostatics were good too,they dont have much problems except belt slipping its an easy fix this new tractor u need service man right away.

Hi, remove the battery and battery carrier, clean all grass and debris from the hydrostatic drive, cooling fins and fan. Your problem is most likely the hydrostatic drive over heating. Hope this helps, regards Phil.

Transmission trouble. Engine runs fine. Will not go forward or reverse.


I presume that this is a hydrostatic transmission. There is probably a lever/rod on the back of the machine that, when pulled, allows the unit to be pushed or pulled. That lever, when pulled out, will prevent the mower from moving under it's own power.
