Toro Lawn Mower Problems

Toro lawnmowers come in a range of models to suit the needs of most homeowners. Walk power models work for small or medium yards; riding mowers cover larger properties. While a Toro lawnmower can make maintaining your lawn easier, these mowers may periodically experience problems. Resolve most of the issues that arise with Toro mowers yourself if you are able to diagnose the problem.

Engine Does Not Start

Many Toro lawnmower models have electric starter engines, which start when you push the primer button several times and use either the ignition key or recoil starter. In some cases, the engine may fail to start even if you follow proper starting procedure. Gas begins to degrade after approximately a month and becomes more difficult to light, so a mower with stale gas may fail to start. If you have not used your mower in over a month, drain the gas tank and add fresh fuel.

A clogged air filter may also prevent a Toro lawnmower from starting. Debris in the filter prevents air from reaching the carburettor and makes starting the lawnmower difficult. Clean the filter regularly. Replace filters stained with gas, oil or dirt. Worn, damaged or dirty spark plugs may also prevent the mower from starting. Inspect spark plugs for visible damage every 100 hours of operation. During seasons when the mower is in heavy use, replace spark plugs every 200 hours of operation.

Fuse Is Blown

Most Toro electric start mowers are equipped with a 40-amp fuse that provides protection to the mower's electric starter system. It is housed in a fuse box next to the mower's battery. If the engine does not turn over with the electric starter or the battery does not charge, the fuse may be blown. Replace it with a 40-amp plug-in style fuse.

Blade Is Damaged

During operation, a Toro lawnmower's blade may become damaged. If it is cracked, nicked or dull, the damaged blade will affect the mower's ability to cut grass. If you notice that the grass is not being cut or that it is being cut unevenly, the blade may be the problem. Examine it for visible damage. If it is cracked, replace it. Sharpen or replace a dull or nicked blade.

Engine Overheats

The engine of a Toro riding lawnmower may overheat due to an excessive engine load, which you can remedy by slowing the ground speed of the mower. The engine may also overheat if the crankcase's oil level becomes too low. Another overheating problem may occur when debris clogs the cooling fins and air passage under the mower's engine blower housing. Removing any clogs should fix the problem.
