The grass cutter is a familiar agricultural tool for everyone, especially environmental sanitation workers. The grass cutter makes the task of cutting grass quick, saving a lot of labor and time. However, over time, friction can cause the machine to operate poorly, and to address this issue, you need to regularly change the oil for the grass cutter. Why change the oil? How often should you change it? This article will help answer these questions.

Reasons for changing the oil in the grass cutter

For a grass cutter, like any other machine, to function well, the engine must always be in a stable and ready-to-operate condition. To achieve this, one of the top important factors is the fuel used in the machine, specifically the correct mixture of gasoline and oil. This mixture needs to be properly blended and regularly checked and replaced, as its main role is to generate power for the machine and lubricate the crankshaft and pistons to prevent wear and tear. Therefore, if there is insufficient or improperly changed oil, the machine may overheat and degrade quickly, leading to malfunctions during use.

Changing the oil for the grass cutter is essential for machine maintenance to enhance its durability. You should regularly check the oil reservoir to monitor the oil level; if it’s low, you need to replenish it promptly. Typically, the oil level in the reservoir may change due to the following main reasons:

1. Oil turning black: This indicates old oil that has been used for a long time, containing accumulated deposits at the bottom. This deposit layer can corrode the machine, causing it to deteriorate quickly. In this case, you need to completely remove the old oil and replace it with new oil.
2. Reduced oil level: This is a common occurrence in grass cutters. During operation, some oil participates in the process and gets consumed. In this case, you just need to add more oil to fill the reservoir.

The method of changing the oil is not complicated, and anyone can do it. It is essential to regularly check the oil reservoir to timely replace and replenish, ensuring the smooth operation of the machine.

How to change the oil in the grass cutter

Currently, on the market, grass cutters mainly come in two types: 4-stroke gasoline grass cutters and 2-stroke grass cutters. Each machine has a different structure, so the oil change process differs.

Changing oil for 4-stroke grass cutter

Changing the oil for a 4-stroke grass cutter is relatively easier compared to a 2-stroke machine. This is because the 4-stroke grass cutter engine does not directly use the gasoline-oil mixture from the outside but has a separate compartment for oil. During operation, the carburetor of the machine is responsible for mixing the two types of fuel. Therefore, all the user needs to do is observe and timely replace and replenish the necessary oil. You can change the oil based on the condition of the oil level in the compartment or change it regularly every 50 hours of use. The steps for changing the oil are as follows:

Step 1: To drain the oil, remove the oil dipstick and drain plug. To clean the old oil in the compartment, tilt it to one side and use compressed air to blow out the excess oil.

Step 2: Install the drain plug and tighten it.

Step 3: Screw in the oil dipstick tightly. Before that, clean and thoroughly wipe the oil dipstick to remove any old oil residue.

Some points to remember

When changing the oil for a newly purchased 4-stroke grass cutter:

• • Initially, new 4-stroke grass cutters come with maintenance oil, and you need to drain all of this oil to replace it entirely with new oil.
  • For the first time, run the engine until 3 to 5 liters of gasoline are consumed, then change the oil after 5 hours.
  • The second oil change is after the next 25 hours of use.
  • The third change is after 50 hours.
  • Subsequent changes are every 50 hours.
• The type of oil used for 4-stroke engines is SAE 20W – 50 with SG grade or higher.
• The machine should be placed on a flat surface during the oil change.
• For machines that have not been used for a long time, lock the fuel and drain all the fuel from the carburetor.
• The timing of oil changes should be flexible, depending on usage density. For example, if it’s not yet 50 hours but has been a significant period since you started using it, it’s advisable to change the oil.

In conclusion, regular oil changes are crucial for maintaining the optimal performance and longevity of your grass cutter. The engine’s well-being relies on the correct fuel mixture, and timely oil replacements prevent overheating and potential damage. Whether you own a 4-stroke or 2-stroke grass cutter, understanding the specific needs of your machine is essential for proper maintenance.

Changing the oil is a straightforward task that can be performed by anyone. By adhering to a regular schedule and paying attention to the oil’s condition, you ensure that your grass cutter operates smoothly and efficiently. Neglecting this maintenance task could lead to increased friction, overheating, and ultimately, the premature degradation of your machine.

Remember, the key to a durable and reliable grass cutter lies in the attention you give to its essential components. Regularly checking the oil level, its color, and adhering to a consistent oil change schedule will not only save you from potential issues but also extend the life of your valuable equipment. So, take the time to care for your grass cutter, and it will continue to serve you well in maintaining a pristine and well-kept environment.
