It is not possible for the tractor to do work without clean and functioning hydraulics. Therefore, should the hydraulic oil be changed regularly? So how often should you change the hydraulic fluid?
How Often Should Hydraulic Oil Be Changed in a Tractor?
The frequency of hydraulic oil change in tractors depends on 5 different variables. Based on these variables, you can decide how often you should change the hydraulic fluid.
The variables are as follows:
Hydraulic Oil Quality Used
As time passes, the quality of hydraulic fluid deteriorates as it remains in the hose reel or reservoir. Also, if an operator changes the hydraulic fluid only once a year, it is not a problem as long as the oil used is still of good quality.
It is possible to change the hydraulic fluid every four months or once a year. The important factor in this case is whether the old hydraulic fluid is doing its job as efficiently as it should.
Size of Engine in Tractor
The larger the engine in a tractor, the more heat it generates when starting. When an engine produces heat, the hydraulic fluid running through it also generates heat. The hotter the hydraulic fluid, the faster it deteriorates. Therefore, if it is left for too long without replacing with new hydraulic fluid, it may damage various components of the tractor.
It should always be borne in mind that constantly operating a hydraulic system at higher temperatures, such as where tractors are used to apply fertilizers and pesticides, will break down hydraulic fluid much faster than normal.
Hydraulic Fluid Usage
The amount of oil used over time while the tractor is running will determine how often you need to change the hydraulic fluid in the tractor. For example, if the hydraulic system uses 1 gallon for every 4 hours of operation, the hydraulic fluid must be changed four times in the same day. The use of hydraulic oil will determine how quickly it will become contaminated and need to be replaced. For this reason, it is not correct to give the same time for each tractor. This is completely unique.
Type of Oil Used
Synthetic oils have better lubricating properties than petroleum-based or mineral oils. They can also flow better at lower temperatures. Therefore, it is very beneficial to have them in a hydraulic oil for various reasons. However, it can also mean that you need to change your hydraulic fluid more often than the manufacturers recommend. For this reason, you can get information about the hydraulic oil change period by telling a professional about the type of oil you use.
Environmental Conditions
The environment in which the tractor operates also affects the quality of the hydraulic fluid over time. For example, factors such as humidity and precipitation will cause the hydraulic fluid in the tractor to deteriorate faster if it is not changed on time.
Your Tractor's Steering Oil
In modern tractors, the steering fluid is also a part of the hydraulic system and the fluids are drawn from the same reservoir. Therefore, when the hydraulic oil is changed, the steering oil also changes. Therefore, you do not need to take any extra action to change the steering hydraulic fluid.
Changing the hydraulic fluid or hydraulic oil is quite simple and very similar to changing the engine oil. Most tractor manufacturers recommend the following:
- Check hydraulic fluid levels every 50 hours of use and add oil if necessary
- Change the transmission hydraulic fluid and filter. Clean the transmission hydraulic pickup strainer every 1200 hours.
Checking the Hydraulic System Oil Level
You can check the hydraulic fluid level as follows:
- Park on flat ground. Put the range shift lever in neutral, adjust the brakes and turn off the engine.
- Wait at least five minutes for the oil to settle.
- Check the oil level through the sight glass or using the dipstick. At this point the fluid should be up to the full oil level mark.
- If the oil level is low, add oil to the filler neck.
