I have been a Troy Bilt Mustang 50 owner for over 5 years, and during that time, I have had to have the hydrostatic transmission rebuilt 3 times. I have also talked to other Troy Bilt Mustang 50 owners, and it seems that many people are having the same problem. Mostly, people face an oil leaking problem due to leakage in transmission.
And if you have the same problem, you can fix it by replacing the seal. Well, there are plenty of other things that can happen. So, we are here to discuss Troy Bilt Mustang 50 hydrostatic transmission problems and Solutions.
Troy Bilt Mustang 50 Hydrostatic Transmission Problems and Solutions
The Troy Bilt Mustang 50 is a great mower for the money, but if you are going to buy one, you need to be aware of the hydrostatic transmission problems. The good news is that there are a lot of solutions to the problems, and we are going to share them with you.
| Problem | Cause | Solution |
| Oil Leak | Leakage in transmission | Seal it properly or install a new gasket |
| Mower Not Turning On | Pump and motor not working properly | Add fluid to the transmission |
| Noise | Faulty solenoid or loose belt | Replace the solenoid and tighten the belt or replace it. |
| Overheating | Low fluid level | Add more fluid |
| Engine Stalling | Fuel filter problem | Replace it |
| Gear shifting problem | The belt is not tight | Change the belt |
| Faulty Belt | Not having enough strength | Align it properly or change it |
Oil Leaking Issue
The Troy Bilt Mustang 50 is a hydrostatic transmission lawn tractor that has been known to have oil leaking problems. There we find few potential solutions to this problem.
The first solution is to replace the seal on the hydrostatic transmission. You can do this by removing the transmission cover and the pump cover. The seal can then be replaced by removing the old seal and installing the new seal.
Also, you can replace the gasket on the hydrostatic transmission to solve the leakage problem. If there is still oil leaking, replace the O-ring on the hydrostatic transmission.
Mower Not Turning On
The Troy-Bilt zero-turn hydrostatic transmission problems are a result of the pump and motor not working together properly. The pump sends hydraulic fluid to the motor, which turns the blades on the mower. When the pump and the motor are not working together properly, the blades on the mower will not turn.
You can fix this by ensuring that the pump and the motor are working together properly. Also, add transmission fluid into the transmission.
Noise
Another popular Troy Bilt Mustang 50 hydrostatic transmission problem is that it makes noise. And it is usually caused by faulty transmission solenoid. Also, it can happen due to the belt. Replace the belt to solve this problem.
Overheating
If the hydrostatic pump overheats, the first solution is to check the fluid level. If you find the fluid level low, add more fluid. And if it is high, the pump may be overworking, and the fluid may need to be drained.
The next solution is to check the air filter. When the air filter is dirty, it needs to be cleaned or replaced. If the air filter is not the problem, the pump may need to be replaced.
The Transmission Belt Comes Off
First, check the belt tension. Then adjust it properly to make it have enough strength. Also, check the belt alignment.
The belt should be aligned properly. If you still do not find the solution, then replace the belt.
Engine Stalling
Well, there are many reasons that can lie behind this problem. First of all, check the fuel level. If the fuel level goes low, the engine can stall. But that is an easy solution that may not create too much mess.

Unless your fuel filter stops working, then we are afraid you need to change that to get everything working fine.
Gear Shifting Problem
Many complaints have been about the Troy Bilt Mustang 50 hydrostatic Transmission gear shifting problem. The most common complaint is that the transmission slips out of gear, particularly when the tractor is being driven at high speeds.
The easiest solution is to tighten the belt that drives the transmission. This solution, however, is not always effective.
Another solution is to add a transmission governor to the tractor. This solution is effective, but it is also expensive. If nothing works, then you need to replace the transmission.

Frequently Asked Questions (FAQs)
Can you adjust a hydrostatic transmission?
Yes, you can. You can change the threaded connecting ferrules or adjust the length to get better control. However, you must check the user manual to get a better idea about it. By adjusting the control valve, you can adjust the speed as well.
Do hydrostatic transmissions wear out?
Yes, if you apply a heavier load than it can take, this problem occurs. However, hydrostatic transmissions are more durable than traditional mechanical transmissions. They can last for tens of thousands of hours of operation and rarely require maintenance or repair.
Why won’t my hydrostatic transmission move?
Mostly that happens because of the drive belt. Try to adjust or replace the belt. Also, it can happen due to lower or old fluid. A bad tensioner pulley is also a major reason for this problem.
Wrapping Up
Hopefully, these tips will help you to solve the Troy Bilt Mustang 50 hydrostatic transmission problems. If you’re still having trouble, or if the problem is too complex for you to fix on your own, it’s best to take the tractor to a professional mechanic.
However, mostly, it is better to replace the transmission. Before making any of the hard decisions, you can check out the above-mentioned problems, which you can fix easily. Therefore you can cut out an extra cost.
