Why does my craftsman riding mower not work in 2 3 and 4th gear?

How do you fix a transmission on a Craftsman lawn tractor?

This is called a peerless transmission there's label right there and this is common in all these mowers. And it's mounted with one two bolts there one two there and then a couple in the back.

What would cause a riding mower not to go forward or backwards?

A blocked fuel filter can keep gasoline from flowing to your mower’s engine in adequate supply, resulting in a lawn mower that isn’t drivable. Damaged or clogged air filters also can prevent your lawn mower from going forward or in reverse simply because the engine will overheat quickly.

Why is my riding mower going so slow?

Because a lawn mower is powered by a combustion engine that is powered by liquid fuel, clogging is a major issue that slows down or even shuts down performance. In fact clogging can occur in many areas of the lawn mower, including the fuel line, the gas cap, the carburetor, the “needle and seat” and the air filter.

How does a ride on mower gearbox work?

You pull the handle. And you can shift it into reverse by pulling it back or you can shift it into different speeds forward and the further you push the higher the speed is so it's called hydrostatic.

How do I know if my lawnmower transmission is bad?

To check the transmission, carefully watch the transmission when the engine is running. If the pulley is spinning, and the wheels aren’t turning, the transmission is bad. Unfortunately, if this is broken, it may be time to buy a new mower because this part is generally unreplaceable.

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 does my riding mower only go in reverse?

Mower drive belts slipping is major reason some riding mowers won’t move forward or in reverse. These belts connect the energy produced by the motor to the axle hooked to the drive wheels. Old, excessively worn, or defective drive belts can slip instead of relay the energy required.

How do you purge a hydrostatic transmission?

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.

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.

What kind of oil goes in a hydrostatic transmission?

What Kind Of Oil Do You Put In A Hydrostatic Transmission? Hydro-Gear transmissions and pumps should be fluided with either 20W-50 synthetic motor oil or 15W-50 motor oil. It is easy to access and check oil levels on machines with oil reservoirs, as they are mounted to the frame behind the seat.

What is the transaxle on a mower?

A transaxle is a case that contains both the transmission components, differential and the drive axles. We generally use transaxle and transmission interchangeably when talking about todays lawn tractors because all of them use one case to house the transmission, differential and axles.

What is the difference between gear drive and hydrostatic?

While a hydrostatic transmission vs manual uses a hydraulic motor and fluid, manual transmission tractors use a gear box. The number of gears can vary, but a clutch is required to change speed and direction to a different gear.

Can you damage a hydrostatic transmission?

If you attempt to push a tractor with a hydrostatic transmission, it causes fluid to move backward through the pump and can damage the seals. You must disconnect the drive before moving your lawn tractor.

What are the disadvantages of hydrostatic transmission?

Cons. Hydrostatic transmissions are not as efficient as gear transmissions at translating engine horsepower into power take-off, or PTO, horsepower. So if you use PTO-driven implements, double-check that the PTO horsepower of a tractor with hydrostatic transmission is strong enough to handle the tasks.

Do hydrostatic tractors have a clutch?

A hydrostatic tractor is one that uses a hydraulic drive propulsion system in place of a standard clutch and geared transmission. The hydrostatic transmission uses hydraulic fluid forced through a pump to drive the tractor. This fluid drive system is controlled by a foot pedal or a hand lever.

What is the difference between shuttle shift and hydrostatic tractors?

Hydro is more costly to purchase and it also has costs to maintain with fluid & filter changes. Shuttle shift makes a gear tractor easier to use for back and forth, but just like a hydro, there are parts and components that can just as easily fail or wear.

How does a hydrostatic transmission work in a tractor?

The hydrostatic transmission allows a tractor to convert mechanical energy into hydraulic power and then back to mechanical energy. This allows us to infinitely change the variation of forward and reverse speed, and makes our transmission unit smaller without sacrificing power.
