1. Starting problems

This is one of most difficulty Ferris IS600Z problem to solve. This is because they are a number of issues that can result in the engine failing to start. However, in order to solve this problem you need to start by checking if the fuel tank is full. This is because lack of fuel can force the engine to shut down.

3. Unevenly cuts grass

Another common problem with the Ferris IS600Z is that it tends to unevenly cut grass. This problem is mainly caused by blunt blades on the mower and as a result you have to ensure that the blades are sharpened before you start cutting the grass. If this option does not solve your problem you need to check for gouges or dents on your blades, there is a chance that they could be filled with debris or they might have been damaged by rocks during the mowing process. Lastly you should also level your Ferris IS600Z mower according to the specifications on the manual so that grass can be evenly cut.

4. Uncomfortable vibrations

The vibrations are usually caused by blades that are not angled properly. Therefore, you need to make sure that you angle your blades appropriately in order to avoid excessive vibrations. Furthermore, you should also check the bearing to ensure that it’s well balanced and steady to avoid vibrations.

5. Poor functionality of the hydro-gear system

The Ferris IS600Z mower is powered by a hydro-gear system which helps to improve efficiency, reliability and reduce the rate of wear and tear of the lawn mower engine. However, the hydro-gear system of the lawn mower has one downfall as it allows air to enter which then causes a break in connection during the mowing process. In order to solve this problem you need to clean the transmission system but, if you do not have the knowledge and skills its best that you seek assistance form a qualified repairer.

6. Faces trouble in cutting wet grass

Although the Ferris IS600Z is designed to cut wet and dry grass, cutting wet grass can pose as a future problem for this mower. In order to solve this problem you need to ensure that the blades are sharpened so that they can easily cut through the wet grass. The next thing is to slow down the engine and allow the blades enough time to cut the grass. You should not rush the process if you are looking to achieve satisfactory results.

7. Trouble turning wheels

This is also another common Ferris problem which is mainly caused by unbalanced wheels. So always make sure that the wheels on your mower are levelled and have enough pressure before starting the engine. Furthermore, always put enough steering oil to help with lubrication.

8. Engine failures

While the Ferris IS600Z mower is made using a sophisticated engine, it’s sad to note that the engine can face problems in the future. In order to solve these problems you need to ensure that the air filter is not clogged. The next thing to do is to reset the spark plug gap and hope that the engine will start. If these methods fail, try seeking assistance from a professional repairer.
