Lawn mower maintenance.

Lawn mower maintenance.

Lawnmowers endure rigorous hours, manicuring grass to achieve immaculate emerald-green backyard and front landscapes. After it’s suffered extreme manipulation, probably overworked, it certainly deserves a proper tune-up. Too often, homeowners abuse lawn mowers and forget to service them. Many fail to exploit practical maintenance tips and service lawnmowers regularly. Why is preventive maintenance a core component of lawn care? Experts insist that it’s a proactive approach to prolong equipment life and optimize performance for seamless operation. The job of keeping lawns looking healthy and pristine, becomes an almost effortless chore, with optimally functioning lawnmowers. It’s economical to do preliminary checks before calling a lawn mower service Winter Garden specialist. How to stay on top of lawn care maintenance? Try these:

1. Check drive belts and tire pressure.

Faulty tires and drive belts can cause lawn mowers to stall or go out of commission. How well somebody inspects, diagnoses and rectifies the underlying problem truly counts. Low tire pressure decreases trim quality. That said, maintaining correct tire pressure is vital to achieving precision cutting.

Another crucial safety check to exercise proper preventive maintenance is to inspect lawn mower drive belts. If it becomes worn or loose, it poses safety risks to an operator. In some situations, it’s triggered serious malfunctions that eventually damage lawn mower parts. In many ways, conducting regular lawn mower service Winter Garden inspection helps eliminate unwanted out-of-pocket expenses.

Tire pressure check:

1. Power off lawnmower engine. Let it settle until all moving components cease motion. Disengage the key, and the engage brake.

2. Inspect drive tires for correct air pressure. Manufacturers recommend maintaining tire pressure of 10-14 psi.

3. Inflate drive tires and caster wheels to 13 psi, respectively.

Check drive belts:

1. Follow step 1 above.

2. Remove right and left drive belt shields, found on the upper and lower decks of the lawnmower. Once removed, examine the condition of drive belts.

3. Check the lawnmower pump drive belt, undercarriage.

2. Stale fuel corrupts lawnmower carburetor and gas lines. Aged gasoline thickens and increases moisture inside the lawnmower tank, accumulating corrosive dregs. If the gasoline tank has any fuel left over after cutting turfgrass, empty it or run the motor until it’s finished. It’s crucial to exercise this preventive maintenance routine after every turf cutting season, especially before winter.

3. Checking, refiltering and replacing lawn mower oil. Four-stroke lawn mowers require a motor oil change every year. Late-model mowers feature a convenient drain plug for eliminating old motor oil. Earlier models require tilting mower to one side, allowing remaining motor oil to exit the tube. Use a container to collect any remaining motor oil and recycle or dispose of it safely as necessary. As a safety measure, keep spark plug out of reach to avoid contact with oil. Replace with new oil filter or recycle leftovers. Always use a dipstick to gauge motor oil levels.

4. Cleaning undercarriage. Debris, scraps of grass clippings and lingering grime often cling to lawnmower blades. A clean undercarriage optimizes performance, enabling maximum cutting speed, sufficient airflow, and seamless blade rotation. A dirty undercarriage can expose turf grass to fungal diseases. It’s sensible to clean the underside before storing away lawn mower for winter.

Drain the gasoline out of the tank, and disengage spark plug.

Position it on one side.

Get garden hose, start spraying water to loosen debris stuck on the underside.

Combine hot water and soap to produce a cleaning solution, then scrub with a brush to remove all dregs.

Lubricate grease fittings:

Turn off lawnmower motor and allow to settle. Disengage key and enable parking brake.

Apply one or two pumps of multipurpose grease to lubricate fittings.

Grease caster wheels:

Follow the first step above.

Then, disconnect the caster wheel from forks.

Unmount wheel-hub seal guards.

Detach spacer nuts connecting caster wheel and axle. The thread-locking adhesive holds them in place. Disconnect axle with remaining spacer nut locked.
Examine seals and bearings for damage or abrasion. Replace as needed.

Grease bearings with recommended lubricant (see owner’s manual).

Apply new seal to bearing and wheel.

Replace thread-locking adhesive for broken or loose spacer nuts supporting axle assembly.

Connect spacer nut and axle configuration to caster wheel.

Grease the visible section of the axle within the inner wheel.

Repeat the above steps for the second wheel.

The axle assembly shouldn’t extend beyond the nuts.

Remount the seal guards onto the wheel hub. Then, slide the wheel down into housing of caster fork. Reinstall caster onto assembly and bolt together tightly.

5. Air filter inspection. A sputtering lawn mower indicates clogging, particularly the air filter. Sometimes this causes the machine to spurt smoky or oily exhaust. It impedes engine performance, resulting in high fuel consumption.

6. Spark plug replacement. Expert maintenance tips recommend inspecting and replacing a lawn mower spark plug, before fixing any other components that require powering the engine. Loosen the spark plug with a wrench and manually unplug it from the mower. The new spark plug usually features a cavity that prevents the overhanging arm from touching the electrode. This interference can disrupt the electrical charge that powers a lawn mower, resulting in it stalling. Install the new plug and avoid screwing it too tightly, which can compromise the porcelain prong.

7. Sharpen lawnmower blade. When sharpening a lawnmower blade, it’s practical to use a bench grinder or metal file. First, prop up the machine on one side where the underside is visible and hold the blade with multi-grip locking pliers. Next, use a socket tool or wrench to loosen the bolt securing the blade and uninstall it. Then, use the file or grinder to sharpen it.

Doing periodic maintenance tuneup is an effective measure to keep a lawn mower operating optimally. After completing all repairs to lawn mower parts, reattach the wire (spark plug) and start up the engine.
