Step 7: Let Us Spray
Step 8: Blowing Chunks
The lower edge and blades of my mower deck are low enough to the ground, even in the highest position, that the machine must be elevated above the spray washer. I park the mower on a set of open-work metal loading ramps with the sprayer underneath. To be most effective, the cleaning should take place following each mowing, but most importantly immediately after mowing high and/or wet grass. With the water flowing and the blades spinning, the underside quickly gets a good wash, even though I use standard blades, not the optional high-lift blades. This method may not remove a thick longtime accretion of dried clippings from a mower deck, so they might need to be removed mechanically before the spray cleaner is put to use for the first time. Running the blades again after the sprayer is shut off blows any remaining water from the underside of the deck.
