The signs are all present. The evening air is crisp. The leaves are transforming from bright green to yellow, red, and orange. Conversations are centered on Friday night lights and Monday night football. Summer baseball leagues have been replaced by solitude in a deer stand. Fall is in full swing!
For those of us in the industry, this can only mean one thing: The foliar spay season is ending, and it’s time to take care of our equipment to ensure that it will be optimized for the next growing season. I’ve personally destroyed two pump-up backpacks and one hydraulic pump by failing to winterize them until temps were below freezing. When the temperature drops, any remaining water in the unit will freeze. The sprayers must be emptied and flushed with antifreeze.
Cleaning, checking, and protecting our equipment in the fall will save us the frustration of repairs and added expenses when spraying activities begin again. Since the weather doesn’t follow a predictable schedule, the time to prepare for spring is during the winterizing process. None of us want to miss the “perfect day for application” because we are busy fixing broken equipment.
There are three basic requirements for sprayer winterization:
- Clean both the interior and exterior of the sprayer to remove dirt and grime. Any chemical residue should also be cleaned from the system.
- Protect pump, engine, and plumbing from internal corrosion.
- Protect all components from freezing.
