The Kubota TG1860 is a well-regarded garden tractor known for its durability and performance. However, like any piece of machinery, it is not without its problems.
In this post, we will explore some common problems associated with the Kubota TG1860 and provide practical solutions to fix them. Let’s jump in.
Kubota TG1860 Problems
1. Engine Starting Issues
One of the most frequent problems reported by Kubota TG1860 owners is difficulty starting the engine. This can be due to several factors, including a weak battery, a clogged fuel filter, or a faulty ignition switch.
Battery Problems
A weak or dead battery can prevent the engine from starting. Ensure that the battery is fully charged and in good condition. If the battery is old or damaged, replacing it might be necessary.
Clogged Fuel Filter
A clogged fuel filter can restrict the flow of fuel to the engine, causing starting problems. Regularly check and replace the fuel filter to maintain proper fuel flow.
Faulty Ignition Switch
A faulty ignition switch can also be the culprit behind start-up issues. If turning the key doesn’t start the engine, the ignition switch may need replacement.
2. Overheating Issues
Overheating is another common issue with the Kubota TG1860. This can be caused by a dirty radiator, low coolant levels, or a malfunctioning thermostat.
Dirty Radiator
A dirty radiator can impede airflow and cause the engine to overheat. Regularly clean the radiator to ensure it is free of debris and functioning properly.
Low Coolant Levels
Low coolant levels can lead to overheating. Check the coolant reservoir regularly and top it off as needed.
Malfunctioning Thermostat
A thermostat that isn’t working correctly can also cause overheating. If the engine continues to overheat despite having a clean radiator and adequate coolant levels, the thermostat might need to be replaced.

3. Transmission Problems
Transmission issues can manifest as difficulty shifting gears or unusual noises when operating the tractor. These problems can stem from low transmission fluid levels or worn-out components.
Low Transmission Fluid
Ensure that the transmission fluid is at the correct level. Low fluid levels can cause the transmission to malfunction.
Worn-Out Components
Worn-out components, such as gears or bearings, can cause transmission issues. Regular maintenance and timely replacement of worn parts can prevent these problems.
Steering Problems
Difficulty steering or a lack of responsiveness in the steering system can be attributed to several factors, including low hydraulic fluid, worn steering components, or misalignment.
Low Hydraulic Fluid
Check the hydraulic fluid levels and top off as necessary. Low hydraulic fluid can affect the steering system’s performance.

4. Worn Steering Components
Inspect the steering components for wear and tear. Replace any worn parts to restore proper steering functionality.
Misalignment
If the tractor’s wheels are misaligned, it can cause steering problems. Have the alignment checked and corrected if needed.
5. Electrical Issues
Electrical problems can cause a variety of issues, including non-functioning lights, gauges, or other electronic components. These issues can often be traced back to faulty wiring or blown fuses.
Faulty Wiring
Inspect the wiring for any signs of damage or wear. Repair or replace any faulty wiring to resolve electrical issues.
Blown Fuses
Check the fuses and replace any that are blown. This is often a simple fix for many electrical problems.
6. Mower Deck Problems
The mower deck can experience issues such as uneven cutting, vibration, or difficulty engaging the blades. These problems can be caused by a dull blade, an unbalanced deck, or worn-out belts.
Dull Blade
A dull blade can result in uneven cutting. Sharpen or replace the blade as needed to ensure a clean cut.
Unbalanced Deck
An unbalanced mower deck can cause vibrations and uneven cutting. Check the deck’s balance and make adjustments if necessary.
Worn-Out Belts
Inspect the belts for wear and tear. Replace any worn-out belts to maintain proper operation of the mower deck.
7. Hydraulic System Problems
Hydraulic system issues can lead to problems with the tractor’s lift or steering functions. Low hydraulic fluid or faulty hydraulic pumps are common culprits.
Low Hydraulic Fluid
Ensure that the hydraulic fluid is at the appropriate level. Low fluid levels can impair the performance of the hydraulic system.
Faulty Hydraulic Pumps
If the hydraulic system is not functioning correctly despite having adequate fluid levels, the hydraulic pump may need to be inspected and possibly replaced.
8. Braking Issues
Braking problems can pose serious safety risks. These issues can be caused by worn brake pads, low brake fluid, or air in the brake lines.
Worn Brake Pads
Inspect the brake pads for wear and replace them if necessary. Worn brake pads can reduce braking effectiveness.
Low Brake Fluid
Check the brake fluid levels and top them off as needed. Low brake fluid can affect the braking system’s performance.
Air in Brake Lines
Air in the brake lines can also cause braking problems. Bleed the brake lines to remove any air and restore proper braking function.
9. Fuel System Problems
Fuel system issues can lead to poor engine performance or stalling. These problems can be caused by a clogged fuel line, dirty fuel, or a malfunctioning fuel pump.
Clogged Fuel Line
Inspect the fuel line for clogs and clear them if necessary. A clogged fuel line can restrict fuel flow and affect engine performance.
Dirty Fuel
Ensure that the fuel you are using is clean and free of contaminants. Dirty fuel can cause a variety of engine problems.
Malfunctioning Fuel Pump
If the fuel system problems persist, the fuel pump may need to be inspected and possibly replaced.
