FAQ

This filter replaces Briggs & Stratton 792105, 593435, and 593240. It also cross-references with John Deere GY21057, MIU11515, and MIU11517, as well as Bad Boy 063-4000-00, Ariens/Gravely 21544700 and 21544800, and Bobcat 4163205 and 4163206.
This filter is designed for a wide range of V-Twin engines and equipment, including John Deere models Z425, Z245, Z246, Z435, D170, D160, D155, LA155, LA165, and LA175. It is also compatible with engines including 407777, 40G777, 40H777, 445667, and 445877.
For optimal engine performance and longevity, replace the air filter every 50 to 100 hours of operation, or at least once per mowing season. If you frequently operate in dusty, dry, or sandy conditions, you should inspect the filter more often and replace it as soon as it appears clogged or discolored.
A restricted air filter often causes the engine to lose power, run rough, or struggle under a load. You may also notice increased fuel consumption, black smoke from the exhaust, or difficulty starting the engine. If your mower is 'surging' or hunting for idle, it is often a sign that the engine is not getting enough air.
No special tools are required. In most cases, you can access the air filter housing by releasing the clips or unscrewing the knobs on the engine cover by hand. Ensure the area around the housing is clean before opening it to prevent debris from falling into the carburetor intake.
Yes, it is a good practice to check your fuel filter and oil filter at the same time. If you are performing a full tune-up, consider replacing the spark plugs and changing the engine oil to ensure the engine runs at peak efficiency.
