Properly winterizing your sprayer equipment is crucial for safeguarding your investment. As temperatures drop, water left in tanks, pumps, and hoses can freeze, leading to cracks, corrosion, and costly repairs. Equipment that’s not winterized is vulnerable to internal damage, reduced performance, and shortened lifespan. Warranty does not cover freeze damage, so you want to get ahead of freezing weather to protect your equipment.
Taking the time to prepare your STIHL, John Deere, or Frontier sprayer for winter also ensures that your equipment is ready to go when spring arrives. Protecting seals, pumps, and sensitive electronics during the off-season means less hassle in next growing season.
Essential Tools and Products for Effective Winterization
Start your winterization process with the right tools and fluids. At a minimum, you’ll need:
- Clean water for flushing
- Appropriate-sized wrenches
- Manufacturer-recommended propylene glycol-based winterizer fluid
A proven solution is the John Deere Sprayer Winterizer Fluid (Propylene Glycol). This product protects internal components from freezing and corrosion. You can buy it from your local TriGreen Equipment John Deere parts department, or online here.
Ensure that the solution you use is rated for -50 degrees, and do not mix that solution with water. Doing so will dilute it and minimize the protection.
Step-by-Step Guide to Winterizing STIHL Handheld Sprayers
Whether you just have the one handheld sprayer for your home or dozens for your fleet, winterizing your sprayers is a great way to ensure that they last longer. It’s also a great time to check for leaks, dry rot and other regular issues!
- Empty The Tank
Empty the tank completely and rinse thoroughly with clean water to remove all chemical residues. This is a critical step for winterizing herbicide sprayers. Run clean water through the pump and spray lines.
- Run Winterizer Fluid
After rinsing, run the winterizer fluid through the system according to the manufacturer’s instructions. Ensure all internal passages, including nozzles and hoses, are filled with the winterizing solution.
- Remove Filters & Store
Remove and clean filters, then store them in a dry place. Store the sprayer in a protected area away from the elements. Disconnect the battery if equipped and keep it charged over winter.
Steps to Winterize a Frontier Sprayer
1. Begin by draining the tank, lines, and pump. Flush the entire system with clean water to eliminate any remaining solution or residue. Thoroughly wash the machine to remove any dirt, mud, or residue.
2. If the sprayer is equipped with foam row markers, run the sprayer until no foam is generated.
3. Remove the line caps at the end of the stainless-steel wet booms if equipped.
4. Add the recommended amount of John Deere Sprayer Winterizer Fluid to the tank. Consult your operator’s manual for the recommended amount. Cycle it through the pump and out through all nozzles to ensure complete protection of all internal components. If equipped, ensure the anti-freezing solution reaches the foamheads. Ensure all liquid is drained from the system.
5. Remove and inspect all strainers and screens for debris.
6. Inspect the entire machine for any won or damaged components prior to storing the machine. This includes hoses, couplers and fittings. Repair or replace these parts to prevent early season downtime. Lubricate all grease points. Consult your machine’s operator’s manual for additional details on grease points.
7. Store the sprayer away from direct sunlight, indoors or under direct cover, in transport position.
End of Spraying Season Checklist to Winterize John Deere Row Crop Sprayers
These winterization steps are for sprayers that have already been through the chemical cleaning process. These sprayers should contain only water in the solution system.
1. Drain all liquids from the tank, pump, and boom lines. On front fill sprayers, open front fill isolation valve and use front fill purge valve to push any water in front fill hose tank to the solution tank. Rinse thoroughly until all residues are cleared from the system.
2. Fill the system with John Deere Sprayer Winterizer Fluid, circulating it through every part of the sprayer. Make sure it reaches the pump, boom, and nozzles. This protects against freeze damage and corrosion during storage.
3. Prepare foam markers for storage to prevent damage from liquid freezing in control boxes and lines. Drain all liquid from tank and lines, flush and purge all liquid from the foam marker system.
4. Clean or replace filters and strainers, and store your sprayer in a dry, sheltered location. For self-propelled sprayers, follow operator’s manual recommendations for engine and hydraulic systems. Ensure the fuel tank is filled with winter grade diesel fuel or treat the tank with fuel stabilizer.
Expert Tips to Prevent Costly Damage During Cold Months
Always consult your owner’s manual for specific winterizing guidelines or checklists unique to your sprayer model. Label hoses and nozzles if you remove them to make spring reassembly easier.
Inspect all seals, gaskets, and fittings for wear before storage. Consider scheduling a winter maintenance service if you’re unsure about any part of the process.
