In this brief guide, we are going to provide you with the common John Deere 100 series transmission problems and what are the solutions to these problems.
John Deere 100 series transmissions are used primarily in their lawnmowers. This transmission works mainly by belt-driven on lawnmowers and by the shaft on tractors. However, there are many problems with John Deere 100 series transmissions and we’ll tell you how you can solve them.
What are the common problems with John Deere 100 series transmissions?
Most of the common problems with John Deere 100 series transmission are:
- Pulley squealing noises
- Hydraulic system overheating
- Difficulty shifting
- Hydrostatic Transmission pump failure
- Cold hydraulic system malfunction
Why are Pulley squealing noises a problem with John Deere 100 series transmissions?
These John Deere 100 series transmissions are not manufactured to make such squealing noises and if you are hearing such unpleasant noises while driving then you should check with your mechanic as this might get a serious mechanical issue.
What signs are shown by this John Deere 100 series transmission problem?
You will hear these noises while driving and will be very unpleasant to your ears which can be taken as a sign that the transmission is having some problem.
What is the solution to this John Deere 100 series transmission problem?
Normally this sound means that a component within the assembly needs to be replaced as it might be worn out. The entire assembly from which the sound is coming must be removed and rebuilt to fix this problem.
Why is the Hydraulic system overheating a problem with John Deere 100 series transmissions?
Because transmission gears and shafts tend to get damaged, worn, and malfunction under high heat levels. This results in lower than the acceptable performance from the vehicle and high fuel consumption as well as lowering the life of mechanical components in the gearbox.
What signs are shown by this John Deere 100 series transmission problem?
Usually when an hydrostatic transmission overheats an error is shown. This error is not immediately visible on the screen but requires a diagnostic tool to get these actual error codes.
What is the solution to this John Deere 100 series transmission problem?
After cooling down the transmission check the gearbox oil for its condition. Change it if it is too thick and completely black. Also, check your clutch if it is the problem behind this malfunction.
Why is Difficulty shifting a problem with John Deere 100 series transmissions?
You would want a seamless and easy shift even at low throttle input, so if your John Deere 100 series transmission is shifting harshly or with difficulty even at low speed then there is definitely a problem.
What signs are shown by this John Deere 100 series transmission problem?
You would immediately notice and sense if the John Deere 100 series transmission is shifting with difficulty from one speed to another as this is one of most important issues with John Deere 100 series.
What is the solution to this John Deere 100 series transmission problem?
Firstly try replacing the transmission pressure sensor, if that doesn’t work then check for an oil leak in the servo assembly of the particular speed. These are primarily two fixes for this problem.
Why is Hydrostatic Transmission pump failure a problem with John Deere 100 series transmissions?
When air finds its way into the hydraulic system by a faulty pump or a system breach, the hydraulic fluids become contaminated and that will cause drivability problems to your John Deere 100 series transmission.
What signs are shown by this John Deere 100 series transmission problem?
You would immediately notice and sense if the John Deere 100 series transmission is shifting slowly from one speed to another as this is one of most important issues with hydrostatic transmissions
What is the solution to this John Deere 100 series transmission problem?
You can consider purging your hydrostatic transmission if your hydraulic motor is way too slow or if you’ve got air trapped in the system and causing problems.
Why is Cold hydraulic system malfunction a problem with John Deere 100 series transmissions?
If your John Deere 100 series transmission is too cold, it becomes a serious threat to your system. First, the hydraulic fluid becomes thick and unable to reach the pump. In the long run, the hydraulic system will be unable to dissipate heat and damage the transmission.
What signs are shown by this John Deere 100 series transmission problem?
You would notice on the sign dashboard if your hydraulic system is too cold to work and needs some preheating to start working.
What is the solution to this John Deere 100 series transmission problem?
You would need to fill some anticoagulant in your transmission fluid to stop it from becoming too thick. Also, if the temperature sensor is detecting a low temperature too frequently then there is a need to visit your mechanic.
How to diagnose these common problems with John Deere 100 series transmission precisely?
If you are an experienced driver then you can use common diagnostic tools such as OBD-II immediately and fix those errors. For others, the only way to precisely diagnose these signs is to visit your local mechanic or service station who will have a more accurate diagnostic tool to check these signs.
How to prevent getting these problems in the first place?
Regular maintenance is an easy way to extend the life of your transmission. Failing to have your transmission serviced on time, will result in catastrophic wear to internal components, which include the hydraulic system which is the heart of the hydrostatic transmission.
FAQs: John Deere 100 series transmission problems
Is the John Deere 100 Series any good?
John Deere 100 Series range from a small, inexpensive, 42-inch riding mower for flat 1/4 acre lawns to a 54-inch lawn tractor that can easily mow 3-5 acres a week. If you want an affordable lawn tractor and the best cut possible the John Deere 100 Series is the best choice.
How long will a John Deere 100 series last?
John Deere say that the 100 series are made to mow less than 1 acre of flat lawn and then if you don’t use it for anything else they should last 8 to 10 years. But this number also depends on the type of care and maintenance you take of the lawn mower.
