Why does my hydrostatic transmission won’t move?

Failure of any mechanical component, a broken hose, or clogged filter will cause tractor hydrostatic transmission problems. But the most common issue will be the oil itself. In the transmission section of your operator’s manual, you’ll find a section that covers oil viscosity.

How do you troubleshoot a hydrostatic transmission?

Troubleshooting Hydrostatic Drives

If the system is overheating, check the oil level in the tank, inspect the heat exchanger, check the inline pressure filters, inspect the crossport relief valves, and check the pump and motor case drains for excessive bypassing.

Why won’t my riding lawn mower move forward or reverse?

If your riding mower won’t move forward or reverse, check to see what the wheels are doing. If they are spinning, you could just be stuck or have a flat tire. On the other hand, it could be something simple, like forgetting to release your break.

Why will my mower run but not move?

If your riding lawn mower won’t move, the problem could be a broken ground drive belt. If the riding mower is slow and sluggish, the ground drive belt could be so worn that it slips. Either way, follow the steps in this repair guide and video to replace the ground drive belt on your lawn tractor.

What would cause a zero turn mower not to move?

Weak Hydrostatic Transmission

Zero-turn or riding lawn mower parts also stop working due to issues in the hydrostatic transmission like oil leakage, bad drive belt, faulty tensioner pulley, old oil in the hydrostatic transmissions, etc.

Can you damage a hydrostatic transmission?

As components wear, higher levels of debris will build up in the hydraulic oil. “This debris can cause secondary damage to the HST system,” says Gidaspow. “So it is very possible to get further damage when operating a hydrostatic transmission that is worn excessively or damaged.”

How often should you change hydrostatic transmission fluid?

The HT-1000 transmission fluid only needs to be changed once every 1000 hours, as opposed to as early as 500 hours with other brands. Our Hydrostatic Transmission Fluid HT-1000™ is a synthetic transmission oil engineered to provide maximum durability and long life for heavy-duty hydrostatic drive systems.

How much does it cost to replace a transmission on a riding lawn mower?

You Need a New Transmission

A new transmission will cost less than a new engine—usually between $400 and $500—but if your lawnmower is nearly the end of its estimated lifespan—and if you only need a $500 new model—then it’s best to start fresh.

Do you need to change hydrostatic transmission fluid?

Replacing hydrostatic fluid is normally not necessary, unless the drive system is in need of some other internal service or repair.

What kind of fluid do you put in a hydrostatic transmission?

The fluid recommended for Hydro-Gear transmissions and pumps is a 20W-50 motor oil or 15W-50 synthetic motor oil. If the machine has oil reservoirs, they are mounted to the frame behind the seat, for easy access and oil level check accessibility.

What type of oil goes in a lawn mower hydrostatic transmission?

For use in hydrostatic transmissions in zero turn, stand on and riding mowers requiring a high viscosity transmission fluid, either 20W-50 or 15W-50.

Can you use hydraulic fluid in a hydrostatic transmission?


The hydrostatic transmission transmits energy using hydraulic fluid.

Is hydrostatic fluid the same as hydraulic fluid?

Hydraulic fluids for hydrostatic application are called hydraulic oils. In the hydrostatic application, applied pressures are high and the flow rates are low. That is why hydraulic oils must be non-compressible fluids that transfer power within a system or piece of equipment.
