How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

Spark Plugs

When a spark plug becomes fouled, the tips become coated with fuel, carbon, oil or dirt. This interference limits the ignition power needed for mowing on level or uphill surfaces. Maintain your spark plugs by changing them every season or regularly removing and cleaning the tips.

Worn bearings about to fail completely often make grinding noises, as well as unusual vibrations. The mandrels holding the mower deck`s cutting blades contain two bearings that need frequent lubrication to keep the bearings working properly. As bearings dry and overheat, seals fail and dirt enters the mechanism.
As a general rule, avoid slopes that are steeper than one foot of incline for every three feet of horizontal width. Most lawn tractors and zero turn mowers can handle slopes that are only one foot of incline for every four feet of horizontal width. Know your model`s limits and stick within those boundaries.
One of the disadvantages of hydrostatic drives is that the majority of the oil stays in the loop and doesn`t return to the reservoir for cooling. One way to return some of the oil back to the tank is by using a hot oil shuttle valve.
Failure of any mechanical component, a broken hose, or clogged filter will cause tractor hydrostatic transmission problems. But the most common issue will be the oil itself. In the transmission section of your operator`s manual, you`ll find a section that covers oil viscosity.
If you hear this grinding noise both while you`re driving and idling, it`s possible that worn-out bearings are to blame. If the grinding noise comes when you shift, it`s likely due to a worn clutch. Grinding when you turn a corner could be due to a CV joint that needs to be replaced or another suspension issue.
Additionally, when mowing perpendicular to the hillside, always mow downhill if you have the option. It`s always better to go the long-way around and circle around a hill if it means you can avoid mowing uphill. Mowing up a slope puts far greater strain on equipment, and increases the risk of losing traction.
For more than a decade, landscapers in 35+ countries have chosen SPIDER mowers as their solution to safely maintain the steepest and most difficult terrains up to 60 degrees.
Hydrostatic mowers are designed for flat terrain and may not have enough power to handle steeper inclines.
Grinding gears, starting and stopping during operation, and the wheels not rotating with the pulley are common signs that your mower`s transmission is breaking down.
Although cavitation is much more common with hydraulic systems, it can also seriously damage hydrostatic transmissions. Caused when gases in the fluid vaporize, it`s characterized by noisy, erratic transmission operation. “If your machine runs low on hydraulic fluid, the hydrostatic pump can draw in air,” says Beesley.
They are filled with the specified pump fluid to match each pump design and then sealed by each manufacturer at their factories. Replacing hydrostatic fluid is normally not necessary, unless the drive system is in need of some other internal service or repair.
For most effective results, a lawn mower deck should have a pitch, or height difference of 1/8-inch to 1/2-inch between the front of the deck to the back of the deck.
The slope limits of 15 and 22 degrees are based on instructions provided by manufacturers. 0- to 15-degree slope — riding mowers or tractor mowers are approved for these areas. 15- to 22-degree slope — tractor mowers are approved for these areas.
The solution: You`ll need to replace the worn-out wheel bearing. If you`re handy with cars, you can do this yourself. will cost roughly $60 to $150, depending on the type of car you drive. If you get a mechanic to replace a wheel bearing, it will cost around $300.
When your engine is lubricated properly with fresh oil, it should run fairly quietly. As the oil ages and it loses its ability to lubricate the components, the parts will start to move harder against one another causing friction and grinding. These rattling, rumbling, and knocking noises will be hard to miss.
Health Dangers of Grinding Dust

A condition known as pneumoconiosis or “dusty lung” affects many workers that don`t have access to proper filtration and ventilation. The result is scar tissue build up in the lining of the lungs that contributes to serious, chronic lung problems.

When your engine oil is running low, your engine`s components stop receiving the lubrication they need to function properly. Once this happens, you may start to hear clunking, knocking, ticking, or grinding noises coming from your vehicle`s engine.
A common cause of grinding noises under your car are failing wheel or hub bearings. Wheel bearings allow the wheel and tire to rotate and are designed for low friction, while hub assemblies have an additional responsibility of securing the wheel and tire to the vehicle.
Common causes: Worn bearings; main, rod, or thrust. Damaged or worn main bearing noise is loudest under heavy load. Check your oil dipstick for any metal reflections. Metal shavings in the oil is one of the first indications of your main bearing material sloughing off.
Loud squeaking or squealing noise while accelerating could mean there`s a problem with your engine belt. It could mean the belt`s loose or worn. Or it could mean that one of the belt`s pulleys is starting to fail. Loud rumbling noise when accelerating might suggest there`s a problem with your exhaust system.
Using a riding mower on a hill can be risky because some types of mowers tend to slide or skid downhill or roll over when not operated correctly. Mowers that do not have front-wheel steering, such as zero-turn-radius mowers, and top-heavy lawn tractors are the most prone to accidents.
Ventrac mowers can be configured to mow a 30-degree slope! Once you have selected the right machine for the job, remove any debris or obstacles on the slope, including rocks, sticks, and other hazards that could cause the mower to tip over or lose traction.
Zero-turn mowers can also only operate in a horizontal cutting pattern. Taking a very sharp turn can cause the mower to roll over, so mowing at a steep angle can`t be done safely. OSHA actually recommends that zero-turn mowers not mow any hills steeper than 15 degrees.

Mtd 19 In. 173 CC OHV 3-In-1 self propelled. Drive will not engage. Appears as if the belt is too loose even when the drive control bar is depressed all the way. Is this adjustable? This mower hasn’t enough hours on it to stretch the belt, it seems in great shape.
ANSWER : Between the handle and the connection to the drive system, look for adjustment screw or nut and screw on cable. Maybe even check the spring tension, if handle is spring loaded and the spring is stretched it will not engage drive system. If no adjustment to be found then you must get new belt. Good Luck…
