You may have a drive belt that is worn or broken. Check the drive belt for slack condition see if it is not slipped off idler pully wheels or the belt tensioner. I had one that was streched out and was very slack on the pully wheels - I had it replaced with new one and was fine to go. There is a device on the back of your tractor to release the transaxle for manual pushing your tractor about with out starting the engine. Make sure the device is positioned correctly for running mode (engine) - There is a symbol on the back to help you know what to do. The tractor manual has good trouble shooting info and if you don't have one, try googling for it with the model number of your tractor - you will be able to download one free to your computer for viewing it.

Good luck!

SOURCE: Husqvarna, GTH2454T Hydrostatic power loss.

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.

SOURCE: Hydrostatic drive is weak

Try pulling back on the left foot pedal. This manually adjusts the drive belt tension and is a sign that the engine pulley has worn to the point the belt looses traction. A local repairman told me this last week and mine works fine now although in the very near future I'll need to replace the pully. Good luck

SOURCE: After a couple passes tractor will not climb hill.

To me it sounds like the hydro unit has developed internal leaks and the pressure lowers as the oil thins from heat.These trans axles are usually replaced as an unit but some can actually be the dealer to see if you can get parts or whether you need to replace the whole thing.I assume you have already tried a new drive belt,tensioner ect. and if so you are down to the trans axle.You may buy some time buy getting rid of the low viscosity oil in the rear end and go to regular hydraulic oil.

SOURCE: Where should I drill a fill hole for my MTD made

Why do you have to drill? No plug? Check out the back of that thing, the plug might be on the side, the back, the front, not necessarily on the top. The fill plug will be the level too, fill it up till it seeps out. Then plug it up. Hope this helps.

2005 Kia Sorento - in 4 wheel drive, on dry pavement, going slow in forward, turning a corner to the left the rear drivers side wheel tries going in reverse and when turning right the passenger side wheel...

Yes, this is normal while in four wheel drive on pavement.
I will try and explain why.
In four wheel drive the front and rear drive axles are linked together by a chain in the transfer case and gears in both axles. This is a direct link with very little play between the front and rear axles.
When cornering a rear wheel will spin faster, or slower depending on the direction of the turn. this causes a binding in the drive line because the drive line wants all the wheels to turn at the same speed. So the wheel "skipping" going in reverse, is the drive lines way of compensating for the different speed of the wheels turning.
Never should a four wheel drive be used on dry pavement. I could cause a break in one of the drive line components. On a slippery surface , snow, mud, gravel, grass, There is enough slippage in the surface to aloow the driveline to compensate for the different speeds of tire rotation.
So do not try at highway speeds on dry pavement.
Your four wheel drive system is working just fine.

Perhaps you are low on gas and because your tank is tilted as you wheel backwards up hill, the gas line is not getting what little gas is in the tank.

Cruise control will not maitain the speed it is set on. going up a hill it gets slower and going down a hill it gets faster

My experience is that cruise control works on level roads, uphill you have to control speed yourself same for downhill. Exception is very powerful cars. Did it maintain speeds before? (uphill + downhill)

For an Embassy shredder, the forward function is not working.

I was able to figure out the solution for this by taking apart the shredder.

My model is a TX61B. There is a piece of plastic that is attached to an internal sensor. You can see it below the shredder slot with a flashlight. if it is sticking out, the sensor is not tripped, and the forward function stops.

To reactivate this, just put something down the slot like a thin screwdriver to push the plastic lever back, reactivating the forward function.

I could see this being caused by running too much paper in reverse mode, which I recently did.

Count the shifts. It sounds like you are going into overdrive and staying there. Overdrive is too long legged to pull most hills unless you are really flying.. good luck

Shoprider deluxe te-889af loses power when reversing

I think that this is usual to have a slower reverse speed for safety.But on your shoprider you should have 4mph and 8mph ,usually if you are at 8mph it won`t reverse at that speed, you have to go to 4mph ,look infront of you there is a dial this controls the speed that you go forward and reverse.If reverse speed needs to be increased turn the dial up,but don`t forget this also increases forwards.
