Cleaning the Radiator

Service Interval: Before each use or daily
To prevent the engine from overheating, the radiator must
be kept clean. Normally, check the radiator daily and, if
necessary, clean any debris off these parts. However, it will
be necessary to check and clean the radiator frequently in
extremely dusty and dirty conditions.
Note: If the mower deck or engine shuts off due to
overheating, first check the radiator for excessive buildup of
debris.
Clean the radiator as follows:
1. Open the hood and secure the prop rod.
2. Loosen the flange nut securing the clean out cover to
the underside of the rear frame
cover to the side to expose the clean out hole in the
