Top 5 John Deere Mower Problems
Though knowing whether it’s a DIY remedy or a task for a repairman helps one negotiate typical riding mower issues, it might be overwhelming. Here, we highlight five frequent problems observed by Sears Home Services professionals, along with troubleshooting advice to handle each one properly.
Common problems with riding mowers are starting troubles, engine stalling, rattling or humming noises, uneven performance, and poor grass cutting.
Troubleshooting these issues calls for testing fuel purity, scrutinizing spark plugs, confirming battery operation, looking for belt wear and tear, and lubricating moving parts.
While certain issues could call for professional repair—for example, replacing damaged components like carburetors or belts—others might call for DIY solutions like altering gasoline and cleaning filters.
Spring is in full swing, so it’s time to start your riding lawn mower. But, like any other machine, riding mowers don’t always operate as they should, particularly following a long winter’s storage.
Here are five typical riding mower issues Sears technicians find, along with advice on how to handle them.
1. The Engine Cranks But Fails to start. Old fuel, spark plug corrosion, unclean air filter, or ignition switch problems are likely the culprits.
Do-it-yourself repairs:
- Substitute new gasoline for old fuel.
- Check the spark plug for rust and change it if required.
- Inspect the air filter and clean or replace it if it is unclean.
- Should the engine still not start, use starting fluid as a last option.
Required Technician: If the problem continues after these tests, the ignition switch may be defective and require expert care.
2. Your engine turns over but dies fast
Probably a battery problem, broken seat switch, or electrical shorts.
Do-it-yourself repairs:
- Try again after charging the battery for 24 hours.
- Make sure the seat switch is correctly linked.
Technician Required: Should the engine keep dying or the seat switch be properly connected, the switch could have to be changed, or an electrical short requiring professional examination could exist.
3. The rattle and hum of the engine is problem number three.
Probably caused by: Loose components, worn fan belt, or motor lubrication requirements.
Do-it-yourself remedies:
- Check the fan belt for wear and damage; change it if required.
- Oil the motor per the manufacturer’s directions.
- Tighten any loose components that can generate vibration.
Technician Required. Professional servicing might be needed to identify and fix the problem should it continue, or if you doubt the noise’s origin.
4. Rough Running Is a Problem
Probably a clogged carburetor or broken flywheel key.
DIY Repairs: Examining and maybe changing the carburetor if it is clogged.
Check the flywheel key for damage and replace it if necessary if the rough running has started following an impact, such as hitting a rock.
Technician Required: Problems with carburetors and flywheel keys can be somewhat complicated and call for particular equipment and knowledge for appropriate management.
5. It Doesn’t Cut the Grass
Probably worn or fractured blade belt.
Do-it-yourself repairs: Check the blade belt for any wear or cracks and replace it as required.
Required Technician: Professional servicing can guarantee the mower is correctly mended and safe to use if changing the blade belt does not resolve the issue or if belt problems are unclear.
For any problems beyond straightforward DIY remedies, arrange a repair with a qualified expert to guarantee your engine or mower is fixed safely and successfully.
Expert help can restore your equipment to top condition, whether the issue is ongoing and DIY measures have not resolved it, or it isn’t very easy and calls for professional knowledge.
Tips for Maintaining a John Deere Mower
1. Routine Service is Mandatory
Please don’t wait for the machine to have problems before servicing it. Ideally:
- Change engine oil: Every 50 working hours or at least once a year.
- Replace the air filter: Every season or if it looks dirty.
- Replace spark plugs: Every 100 working hours.
- Clean the carburetor: If the engine starts to rust or waste.
2. Check & Sharpen the Cutting Knife Regularly
- Sharp blade = cleaner cut + lighter working machine.
- Sharpen the knife at least every 25-30 hours of use.
- Check balance: Unbalanced blades cause vibrations and damage the deck.
If it starts to *drag* when cutting, that’s a sign the knife needs sharpening!
3. Check the Electrical System
Cables and switches are like the “blood vessels” of a machine:
- Make sure there are no frayed cables or loose connectors.
- Check the function of all safety switches (seat switch, brake switch, PTO switch).
- Clean the battery terminals and check the voltage regularly.
4. Maintain the Transmission and Gearbox
Especially for the hydrostatic series:
- Change the hydraulic oil according to the manual; don’t wait for it to break down.
- Check the belt and pulleys: make sure they are not loose or worn.
- Use only John Deere recommended oil/hydraulics (or equivalent quality).
5. Don’t forget to clean the mower after use
It’s simple, but many people are lazy:
- Wash the deck of dirt, dry grass, and mud.
- Spray under deck with water (many models have a special cleaning port).
- Store in the shade, away from rain and direct sun.
> Grass that sticks to it will cause the deck to rust over time, you know! ⚡
6. Watch for Strange Signs
If it starts to appear:
- Rough voice
- Brebet machine
- Uneven grass cut
- Smell of burning oil
