7 Common problems of ZT HD 52

Many problems can occur due to user errors. That is why you should handle the lawn mower by following the user manual. With proper maintenance and troubleshooting, it is possible to reduce the problems on a large scale. 

● Problems with starting

The problem with starting is often caused by not enough fuel. So, check the fuel first when you fail to start your Gravely ZT HD 52 lawn mower. If there is enough fuel, and it still would not start, check the air and fuel filters for clogs and debris. Often the debris gets clogged in the filters and prevents air and fuel from flowing properly, and this prevents the mower from starting. Cleaning the filters might solve your issue in this case.

However, if this is not the issue, check the ignition switch and wire connection if they need replacement.

● Smoke coming out

Smoke coming out is a problem that should be taken seriously. It can occur due to a lot of reasons. Check the engine oil level. Smoke can come out due to low oil levels. You can try adding oil to solve this problem, but it might need a professional repair sometimes.

Oil spilling or too much oil in the crankcase can also cause smoke to come out of the mower. Excessive oil can cause the engine to overheat, causing oil to leak into the cylinder via the valve system. Blocked air filters can also cause smoke. Make sure to clean it or replace it if it is too damaged. And if this does not solve the issue, check for internal problems and check the piston ring.

● Starting then dies

If you experience that your Gravely mower starts and then dies after some time, then it is a severe problem. You need to troubleshoot properly because many reasons can be blamed for the problem. This issue usually occurs due to bad fuel. So, check the quality of the fuel and check if it is expired. Drain the fuel and refill it with new fuel of good quality.

Dirty and broken cooling fins can also be blamed for causing this issue. Check the fins and replace them if needed. Also, check for carburetor clogs. If the carburetor is clogged, clean all of the carburetor’s parts. If necessary, replace the component.

● Transmission problem

A faulty hydraulic chain or gear might make a Gravely lawn mower’s hydrostatic transmission seem feeble. A weak transmission can also be caused by old hydraulic oil or a lack of oil in the hydraulic tank.

To troubleshoot this problem, you need to check the hydraulic oil. Old or expired oil can cause the problem. So try replacing the oil to solve the issue. Also, make sure to check the tensioner, pulley and belt. Replace the pulley and belt if they are worn out. Also, try greasing the tensioner arm. This might solve this issue.

● Vibrating problem

Vibrations might be caused by small debris caught in your Gravely mower, worn engine mounting nuts, or defective mower deck components. Check the mower clutches as bad clutches can cause vibrating problems. If they are damaged, replace the clutches.

If that is not the case, then check the blade components. If the blades are damaged, replace them. Damaged blades can cause vibration. Also, check the blade spindle. If there is any grass or weeds stuck in the spindle, that might be causing vibration. Clean the blade spindle properly to solve the issue.

● Leaking gas problem

Your Gravely zero-turn might be having gas leaking issues due to failed and dirty carburetors. The carburetor can accumulate particles left behind from old gas, resulting in obstructions or component failure. Replace any broken components in the carburetor after cleaning it.

A faulty fuel pump or a damaged fuel tank can also cause the issue of leaking gas. Check the components and replace them if you find them faulty. If this does not solve the issue, then check the gas cap and shut-off valves. If they are faulty, replace them.

● Cuts uneven

When your mower produces uneven cuts, it is mostly the blades to them. The blades might not be installed properly, or the blades might become worn or bent. So, you need to check the blades. Replace them if they are worn. Sharpen them if needed and make sure the blades are being correctly installed.

Check the mower deck if these measures do not solve the problem. If it is too damaged, then replace it. Mower decks can get easily damaged due to too fast ground speed. So, be careful about the speed the next time. And if the deck is clogged, only cleaning it would solve the uneven cuts problem.
