Maintenance Tips W
To Keep Your ZTR Running
hen equipment, any equipment, does not work as it should, it is frustrating. It can mean costly repairs and then perhaps the worst part, lost hours and productivity. Professionals need their zero-turn mowers (ZTR) to be just as reliable and ready to go as any other machine in the fleet. One of the best ways to ensure dependable operation and good performance from a ZTR is a commitment to routine maintenance. These are the five areas to watch when building a basic zero-turn mower maintenance program. Note: Before proceeding with any maintenance, always consult the operator’s manual, wear appropriate safety gear, park the mower on a flat surface, and ensure the engine is off and cool.
1. Air Filter
Dirty air filters do more than hamper a mower’s performance, they create inefficient operation that wastes fuel. Worse yet, if they allow dirt and other debris to enter the engine, the result can be permanent damage. Check the air filter at least monthly to assess its condition. Those who work in dry, dusty, or dirtier conditions may want to do this step more frequently, as well as those who are at the height of their busy season and are logging more daily hours on their ZTRs. Furthermore, consider seasonality when establishing expectations for the air filter’s lifespan. Fall especially can be a drier time of year, with added tasks like bagging leaves
putting greater stress on the filter. It is not uncommon for professionals to check the air filter weekly, even daily, during these peak times. When it is time to change the filter (or filters, as some ZTRs have dual elements), first clear away any debris from the air intake area. A paper air filter can be gently tapped to remove excess debris, but never blow air on or attempt to clean a paper air filter. Instead, change the air filter as needed. Insert a new, clean air filter and take care to ensure no debris enters the engine.
2. Fuel Filter and Stabilizer
Like the air filter, a clean fuel filter keeps harmful particles from entering and damaging the engine and aids in efficient fuel consumption. The best time to change a fuel filter varies by ZTR so it is best to consult the operator’s
