Experienced gardeners share their insights in answering this question :
This actually sounds like the top pulley on the transmission may be loose and the center hole worn out.

Depending on the actual sound though it may be a bad transmission – sorry. I suggest having a dealer mechanic inspect it.

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

NOTE: Many zero radius turn style riding mowers are equipped with two individual hydrostatic transmissions, a left side and right side, each will have its own manual bypass control lever.
Troubleshooting Hydrostatic Drives

Null the valve if possible. 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.

The hydrostatic transmission transmits energy using hydraulic fluid.
If the PTO clutch is not getting power, if the clutch solenoid is defective, or if the clutch is worn out, the lawn mower blades will not engage. The PTO clutch is not repairable—if the clutch is defective, you must replace it.
Although cavitation is much more common with hydraulic systems, it can also seriously damage hydrostatic transmissions. Caused when gases in the fluid vaporize, it`s characterized by noisy, erratic transmission operation. “If your machine runs low on hydraulic fluid, the hydrostatic pump can draw in air,” says Beesley.
Air in the hydraulic fluid makes an alarming banging or knocking noise when it compresses and decompresses, as it circulates through the system. Other symptoms include foaming of the fluid and erratic actuator movement.
Together, these attributes result in a long-life fluid that truly holds up over time and extends equipment life. Recommended for all hydrostatic drive systems where the manufacturer recommends SAE 20W-50 fluid. Not recommended for engine crankcase.
Powershift PTO engagement problems could be from blocked hoses or fittings, bad connections or ground or the solenoid. Mechanical PTO engagement problems could originate from low air pressure, improper cable installation or back lash too tight.
If the PTO clutch is not receiving power, the clutch solenoid is defective, or the clutch itself is worn out, the blades will not engage. Since a PTO clutch is not repairable, you will need to replace a broken or worn out clutch with a new one.
This operation is crucial to the overall functioning of riding mowers, and thus PTO clutch repair may need to be immediately performed on riding mower models that have a failed clutch. Fortunately, you can fix your clutch irrespective of your experience with PTO clutch installation.
Hydrostatic Transmission – RH – 918-05129A | Cub Cadet US.
The reasons why mower is not moving forward or reverse is that the battery is dead, or due to clogged fuel line. Additionally, malfunctioning transmission, or a broken drive belt, also a faulty spark plug, even when friction wheel isn`t in contact with the friction plate, or damaged Tires.
Grinding gears, starting and stopping during operation, and the wheels not rotating with the pulley are common signs that your mower`s transmission is breaking down.
MTD, which makes Cub Cadet and Troy-Bilt tractors along with the MTD versions, told us the broken gear would most likely lock up the transmission, simply causing the tractor to stop in its tracks.

I have a cub cadet 2165 I just put in a new battery and it is slow turning over any ideas?
ANSWER : If battery is good and everything is hooked up right. Most likely could be the pto clutch bearing. Not the bearing on the pulley but on the clutch inside. Had the same problem, took the spark plugs out got it free. Turned over easy with plugs out, Started right up after and then burned up my bearing. Don’t burn up bearing. If do field assy. For that is 200$ if you can get away with just that. Otherwise 350-400$ for full assy.

I have a cub cadet LT1042 and it is 3 years old…we have replaced the pto 2 times and replaced the belt 7 times what is the deal
ANSWER : You have to have something rubbing under there that isn’t supposed to be, crawl under the tractor and watch the belt go around by hand, if you can turn it. Maybe see what is frozen up, in the wrong place, Gotta be a belt guide is rubbing or a pulley is not spinning. The PTO should last 20 years, all i can think is they got it too tight to start, .010″ min, that is tight, and you must be in Florida picking up a lot of sand? If it was under any kind of warranty, I would raise a big stink about it. Those PTO’s are not cheap. And the belt has got to be $20. I wouldn’t go to a dealer for the belt, unless it is really special, just match it up at the auto parts store, for half the price of dealer. Hope this helps.
