The powerful engine generates just the right amount of horsepower to maintain order in your yard, and the simple controls make it easy to navigate your property’s distinctive landscape.
Gravely ZT 52 will stick with you for a very long time, but just as with other mechanical devices, you will eventually have a problem with it. So, if you’re having trouble, here are the 12 most common problems with the Gravely ZT lawn mower and how to fix them.
1- Mower Starting Problem
Low gasoline, spark plug problems, a clogged carburetor, a damaged clutch, or broken gears are some of the most frequent causes of Gravely lawnmowers failing to start.
Check to see if the fuel in your lawn mower is low or old. As old gasoline won’t ignite because it loses its potency. The spark plug is part of your engine that generates the spark needed to ignite the gasoline. You can clean it with a special solution available in hardware stores. If that doesn’t work, then buy a new one and make sure that it is compatible with the type of engine you have.
Clean the carburetor because it can also be the reason the lawn mower isn’t starting. Your clutch may be at fault if your lawnmower starts but the blades don’t spin. You have two options for clutch repair: do it yourself or hire a professional.
2- Mower Won’t Move
Your Gravely ZT HD 52 won’t move due to common problems including damaged transmission lines, drive bypass valves, a poor drive belt, an issue with your hydraulic system, or clogged air filters.
Your equipment may be going in one direction but not the other due to a failed transmission. When you’re riding a mower stops pulling correctly and a professional is needed to address the problem, we advise doing so.
These are the valves on your mower’s back that disconnect the hydros so you can push it manually. The mower will free roll if these valves are bypassed, but it won’t move. Verify that the bypass valves are set to operate.
The most likely cause of the wheels not moving while the engine is running is a worn-out or broken belt. It can easily break when you are mowing the lawn if it is old and worn out.
The hydraulic system, one of the main engine parts in your mower, is susceptible to failure when not in use for an extended period. Experts concurred that to keep your lawn mower from becoming stagnant, you need to use it frequently.
You must locate the carburetor on your lawn mower. After that, decide whether to clean it or replace it.
3- Mower Uneven Cuts
An unbalanced blade spinning fast will produce a lot of vibration, which will put a strain on the engine and even the spindle and shaft of the blade, leading to an uneven cut. Uneven cuts can also be due to wet grass.
Always keep the blades balanced if you want your mower to last as long as possible and obtain an even cut of grass. Also, to cut even, grass needs to stand upright instead of bending over as the blade slices through it, so avoid mowing lawn when the grass is wet.
4- Traction Issues on Wet Ground
No mechanical component of the Gravely lawn mower is the cause of the traction problems. It’s just that in the rain, you shouldn’t operate a lawnmower. It will almost always produce yield-cutting outcomes and can harm your lawnmower. Moisture can damage the mower’s metal components, its fuel tank, and some of its engine components.
You might be interested in buying tyres with better tread if your zero-turn lawn mower frequently slips on damp surfaces. Alternatively, you might try reducing your tyre pressure to increase the area of the contacts on the ground.
You might also refrain from using lawnmowers when it’s raining. In any case, it is not advisable to mow wet grass.
5- Hydrostatic Transmission Issues
For zero-turn mowers, hydrostatic transmission is a major concern. Basically, it occurs when air replaces oil. The machine cannot supply the engine with the necessary power if it is filled with air rather than oil.
You need to make sure the tyres are properly inflated according to the specifications. Try to use the branded fluid that your manufacturer recommends. Verify that the oil level is at the level that your expert has advised. If necessary, increase or decrease. Check if the filter is clogged with debris or other filth. If so, tidy it up or make the necessary changes.
6- Gravely Engine runs rough.
7- Gravely Engine Overheats
Low coolant, furthermore, clogged air cleaners, air channels, or input screens can hinder the cooling system from functioning effectively, or cutting deck clogs can put too much strain on the engine as it tries to push through with jammed blades, overheating it in the process.
Make sure the carburetor’s mixture settings are correct when the temperature is 80 degrees. At 100, it won’t get too hot. Of course, check to see that the engine’s airflow is proper and that all cooling fins are clean.
8- Deck Vibration Problem
When the mower blades are worn out, out of balance, wrapped around the blade shaft, the belt or pulleys are worn, the spindle or spindle housing is damaged, or there is debris in the deck or beneath your pulleys, the mower deck may start to vibrate.
Refine the blades. Your blades must be equally sharpened on both sides while being sharpened if you want to maintain balance. You can hang your blade on a nail in the wall or use a blade balancer. Your blade shaft should be free of any objects that are wrapped around it. Check the spindle and housing to make sure there isn’t any additional damage. If your lawn mower deck is covered, take them off so you can see the deck belt and pulleys. If you see any cracks or a glazed appearance, you should replace your belt.
9- Gravely Mower Noise Problem
The drive belt is possibly at fault if your lawnmower makes a loud shrieking noise when the engine starts or when you cut the grass. These kinds of noises are frequently made by electrical machinery.
The issue might be resolved by changing the oil, adjusting the blades, or clearing the deck. And if you measure your belt, you’ll notice a thick place where the cords come together and separate; this needs to wear off and the screeching noise will stop.
10- Gravely Mower Does Not Vacuum.
If Gravely lawn mower is not vacuuming, the mulching bag may have been clogged or the vacuum pump is not functioning.
Unclog the mulching bag and check if the vacuum pump is not working. Also, make sure vacuum hoses do not have faulty connections.
11- Gravely Mower Leaks Gas
Due to the gradual component weakening caused by old grass, your mower may have fuel system leaks. It can cause mechanical components to malfunction or weaken and may carburetor starts leaking gas.
To prevent fuel from running out, first remove the fuel line from the carburetor and plug it. With a flat screwdriver, unscrew the small brass cover screw that is located at the very bottom of the carburetor bowl to allow all gas to drain from the system. Reinstall the gasoline line after tightening the screw.
12– Gravely Mower Starts Then Dies.
Your Gravely mower will not work if you have clogged air filters, poor or old fuel, blocked fuel filters, or clogged fuel lines, cooling fins that are plugged or broken may cause your Gravely mower to malfunction and break.
GRAVELY ZT HD 52 Maintenance Tips
Check the Oil: Every time your mower is in the mowing season, check the oil level. It’s time to change the oil if the oil has debris in it or is beginning to appear dark.
Check the Oil Filter: Large particles and trash are kept out of your oil by the oil filter. The owner’s manual’s recommended interval for oil filter replacement is once every mowing season.
Check the Fuel Filter: Your fuel filter prevents extraneous objects from getting into your carburetor, which could cause a blockage. Your mower may stall out or be difficult to start if it is not replaced at the proper intervals.
Check the air filter: The engine is under more strain and burns more gas when an air filter becomes clogged or unclean. The engine runs cooler and lasts longer with a clean air filter. The operator’s manual for your mower may specify that this should be changed once a year.
Check the tyre pressure: A low tyre can make steering difficult, and a mower deck that isn’t level makes mowing unpleasant. Use a tyre pressure gauge to check the pressure in your tyres. Verify that your lug nuts are tight and that your tyres are inflated to the Gravely recommended pressure level.
Don’t let the issues deter you if the Gravely Zero Turn lawn mower is a good fit for your needs. Regardless of the type of mechanical equipment you use, issues will inevitably arise. The best course of action is to regularly check for faults and address them before utilizing them. It is preferable to have a professional handle the repairs on your Gravely lawn mower if you are unclear of how to safely perform diagnostics and repairs on the machine.
