Maintenance Guide: Servicing Your 22” Petrol Lawnmower

A reliable lawnmower is the backbone of a great garden. The Titan Pro 22” (55cm) Kohler High Torque XTX Self-Propelled Lawnmower is a powerhouse, but to keep that zero-turn precision and engine longevity, regular servicing is essential.

Most routine maintenance is quick, easy, and can be done at home. Follow this guide to extend your mower's lifespan and ensure a first-time start every spring.

SAFETY FIRST: Always turn off the engine and remove the spark plug lead before performing any maintenance to prevent accidental starting.

1. Monitor Engine Oil Levels

Engine oil is the lifeblood of your Kohler XTX engine. Running on low or dirty oil can lead to catastrophic engine failure.

• The Check: Use the dipstick to check levels before every use.

• The Top-up: Ensure the oil is within the "Full" markers.

• The Type: Use the manufacturer-recommended oil grade to ensure optimal lubrication and heat dissipation.

2. Use Fresh Fuel (Avoid Stale Petrol)

Did you know modern unleaded fuel begins to degrade in as little as 30 days? Stale fuel is the #1 cause of carburettor clogs and starting issues.

• Freshness: Only buy what you need for 4–6 weeks.

• Storage: Keep fuel in a sealed, airtight container in a cool spot.

• Stabilizer: Use a fuel preservative if you plan on leaving petrol in the tank for more than a month.

3. Clean or Replace the Air Filter

Your mower needs to "breathe" to burn fuel efficiently. A clogged filter starves the engine of air, causing it to run "rich," lose power, and consume more petrol.

• Inspect: Check the filter every few mows, especially in dry, dusty conditions.

• Action: Tap out loose debris or replace the filter if it appears dark, oily, or heavily contaminated.

4. Inspect and Sharpen the Blade

A dull blade doesn't cut grass; it tears it. This leaves your lawn with ragged, brown tips that are susceptible to disease.

Check for:

• Dullness: If the edge feels rounded, it needs sharpening.

• Damage: Look for nicks from stones or bends from hitting roots.

• Balance: An unbalanced blade causes vibrations that can damage the engine crank.

5. Clean the Underside of the Deck

Wet grass clippings are acidic and can corrode your mower deck over time. Built-up debris also disrupts the airflow needed for a clean cut and efficient bagging.

• The Correct Tilt: Never tilt the mower sideways with the air filter down. Always lift from the front so the spark plug points upward. This prevents oil from leaking into the carburettor or air filter.

6. Tighten Moving Parts and Controls

The vibrations of a high-torque engine can naturally loosen bolts over time. A quick "shake test" can prevent parts from falling off mid-mow.

Check these key areas:

• Wheel bolts and handle fixings.

• Drive system tension and control cables.

• Safety lever (OPC) functionality.
