All the discussions that we have done till now, we have a basic idea of the possible problems we could face using the new holland TN645. Now, I will describe all the solutions, so keep reading till the end.

1. Rust Problem

It’s a pretty common problem. Even your new TN65 can rust if you do not maintain it well. You must be careful to stop it from getting rust from the very beginning. If you leave your tractor outside without washing or cleaning, it will rust in a few days. And your tractor might even come to the touch of some chemicals like fertilizer and pesticides, and these chemicals can make it rust.


Rust problem is like a contagious disease for your tractor. It rusts all over the tractor body from one small place. But if you take good care of it, you can avoid it from rusting.

  • Do not park your tractor outside. Always try to park it inside in a dry and cool place.
  • Never leave it on dirt and mud. Clean it thoroughly, especially the tractor body, after every use.
  • Wash off all the chemicals after you pesticide your field with the tractor.
  • Apply paint; it will prevent rust. And if it gets rusted, the paint will cover it and prevent further rusting.
  • Wax your tractor with automotive wax annually. It gives additional protection.
  • Grease the bearings before you leave your tractor in the garage for a long time.  

2. Belt Squealing Problem

 Sometimes, an electric tractor’s belt squeals as soon as you start the engine. It goes away after a few moments, and sometimes it does not. Again, it can happen every time you start or every once after each start. It’s a pretty common problem among tractors.


To begin with, you can fix it by tightening it a bit, like 1 inch, and see the progress. You can spray a little water on the belt and see if it still squeals or not. Dressing the belt might be a temporary solution for this issue.

  • Check if it’s running out of lubrication. And fill the reservoir.
  • Remove the drive belt from the mower deck; if it’s worn and old, replace it with a new one.
  • Check the air and fuel flow; sometimes, the air and fuel flow failure cause this squealing problem.

3. Poor Engine Output Problem

The engine problem is the most crucial problem of any vehicle. There could be a lot of engine problems, such as the engine won’t turn over, the engine turning over but doesn’t start, the engine starting but dying after a few moments, etc. These problems mostly happen with engines that run on diesel. 


First, you should identify your tractor engine. Most of the problem and solution I mentioned here is for diesel engine. Most of the engines in the market are also diesel-fueled. Gasoline engines tend to be more complicated. I am showing every possible solution to engine problems you might have.

  • If your engine does not turn over, it might be a battery problem. If your battery is dead, then the engine won’t start. So, recharge your battery and replace it if needed.
  • If your engine turns on but does not start, you can assume it’s the fuel problem. Check your fuel filter and fuel running tank. The fuel filter might be clogged, blocking the roads for fuel from reaching the engine. Clear your fuel and air filter regularly to avoid this kind of problem.
  • The wrong oil mix can cause the problem where your engine starts for a while and dies after a few moments. Sometimes, the diesel you are using could be mixed with gasoline. Both oils work quite differently, so you should not use a mix of them.

4. Hard Shifting Transmission

In cold weather, the transmission usually gets hard. Because in the cold, the transmission fluid thickens and causes a hard shifting problem until the fuel is warm enough to flow properly. A rich quality synthetic fuel that won’t run thick in the cold will help you in this case. 


If you want to start with the cheapest way to fix this problem, check the transmission fluid level. If the fluid level is low, check for leaks or defects.

  • Raise the fluid level by adding new fluid if it’s low so the transmission can ease a bit. But if your fuel tank seal is leaked or there is any mechanical issue, fix that first, then add the new fuel. Otherwise, the new fuel won’t help.
  • You can tell you are using a really old fluid by smelling it. If it smells burnt and dirty, it’s really old. Old transmission fluid can make the transmission shift hard. Changing the oil from time to time can lessen this problem.

5. Hard Steering Wheel:

If your tractor’s power is running low and out of fluid or grease, the steering wheel gets hard to operate. Sometimes the weight of the front tires causes this kind of problem. The front wheels of your vehicle are linked to the steering wheel. Troubleshooting the linkage of the front wheel would help you with this issue.


  • The sector plate and bushing held the steering wheel together. Sometimes, the pinion gear gets misplaced, and the steering wheel becomes hard. Fix the pinion gear placement. And replace the bushing and sector plate if needed.
  • Sometimes, the steering motor gets bad. Check the fluid level of your steering motor. Add new fluid if it needs. Also, check your valve connection; those should be tight. If they are loose, they will bypass the fluid, and your steering wheel will be hard.

6. Overheating Problems

The radiators of the tractor do not function properly, and the heat rises in the engine and causes overheating problems most of the time. Another common cause is the engine is out of oil. The temperature of your tractor should be around 150 to 180 degrees Fahrenheit.


  • Clean the dirty radiator.
  • Never let your engine run out of fluids.
