Spreader Maintenance: Tips to Keep Yours Working LongerA well-maintained spreader works more efficiently, lasts longer, and helps you apply fertilizers, seed, salt, or other materials evenly and safely. Whether you use a handheld broadcast spreader, a tow-behind model, or a larger commercial unit, regular upkeep prevents downtime and saves money. Below are practical, step-by-step maintenance tips, seasonal checklists, and troubleshooting advice to keep your spreader in top condition.
1. Know Your Spreader Type and Manufacturer Guidelines
Different spreaders (handheld, push, broadcast, drop, rotary, tow-behind, ATV/tractor-mounted) have different parts and service needs. Always consult the owner’s manual first for manufacturer-recommended maintenance intervals, replacement part numbers, and lubrication specifications.
2. Clean Thoroughly After Every Use
- Empty any remaining material immediately after use. Leftover fertilizer, salt, or seed can corrode metal and clog mechanisms.
- Rinse plastic and metal parts with a garden hose. For stubborn residues, use a mild detergent and a soft brush.
- After rinsing, allow the spreader to dry completely to avoid rust. Wipe metal parts with a cloth and apply a light oil if needed to displace moisture.
3. Inspect and Protect Against Corrosion
- Check the hopper, frame, spreader plate, and any exposed metal for signs of rust or pitting.
- Sand away surface rust with fine-grit sandpaper and touch up with paint or a rust inhibitor.
- For salt or de-icing applications, consider a corrosion-resistant spreader or apply extra protective coatings. After salt use, rinse thoroughly and lubricate pivot points.
4. Lubricate Moving Parts Regularly
- Grease bearings and pivot points according to the manual. For many spreaders, a light spray lubricant or multi-purpose grease keeps gears, axles, and linkages moving freely.
- Avoid over-lubricating near hoppers where material can stick to excess grease.
5. Check and Adjust the Agitator and Spreader Plate
- Ensure the agitator (if present) moves freely and isn’t bent or warped. Bent agitators can cause clogging or uneven flow.
- The spreader plate or impeller should be free of dents and spin smoothly. Replace warped plates to restore uniform distribution.
6. Calibrate Frequently for Accurate Application
- Regular calibration ensures you apply the correct amount of material. Follow the calibration steps in your manual, typically involving a known test area and measuring output weight over time.
- Re-calibrate if you change material type (seed vs. fertilizer vs. salt), hopper settings, or ground speed.
7. Inspect Tires, Wheels, and Bearings
- Inflate pneumatic tires to the recommended pressure. Replace cracked or badly worn tires.
- Check wheel bearings for play. Replace or repack bearings when they feel rough or loose.
- Ensure wheels are aligned and spin freely without wobble.
8. Maintain Linkages, Cables, and Controls
- Inspect control cables and levers for fraying or rust. Replace frayed cables and lubricate control linkages.
- Tighten loose nuts, bolts, and fasteners. Use locking washers or threadlocker on high-vibration connections.
9. Replace Worn Parts Promptly
- Common wear items include agitator blades, spreader plates, screens, bearings, and drive components.
- Keep a small inventory of fast-moving spare parts (pins, clips, washers) to minimize downtime.
- When replacing parts, use OEM components when possible to preserve fit and function.
10. Seasonal Storage Best Practices
- Before long-term storage, clean thoroughly and allow to dry.
- Store in a dry, sheltered spot away from direct sunlight to prevent UV damage to plastic components.
- Elevate the spreader or support the frame so tires aren’t bearing the full load for months.
- For tow-behind models, disconnect batteries (if present) and protect hydraulic lines from freezing.
11. Troubleshooting Common Problems
- Uneven spread pattern: Check for a warped spreader plate, clogged openings, or uneven tire pressure. Calibrate and test with water or sand.
- Hopper clogging: Clean out sticky residues, check agitator condition, and ensure the material is dry before loading.
- Drive not engaging: Inspect chains, belts, and gearboxes. Lubricate or replace damaged drive parts.
- Excessive wear/noise: Check bearings, misalignment, or missing lubrication points.
12. Tips for Specific Materials
- Fertilizer: Store in sealed containers to keep dry; dry fertilizer flows better and corrodes less.
- Seed: Use screens or liners to prevent small seeds from falling through and clogging mechanisms.
- Salt/De-icing: Rinse immediately after use, and apply corrosion inhibitors to metal parts.
13. When to Get Professional Service
- Strange noises from gearboxes or drive systems.
- Hydraulic issues on larger tractor-mounted spreaders.
- Major frame damage or worn structural parts. If in doubt, have a qualified technician inspect complex components to avoid compounding damage.
14. Simple Maintenance Schedule (Example)
- After each use: Empty, rinse, dry, lubricate pivot points, inspect for obvious damage.
- Weekly (during heavy use): Check tire pressure, look for corrosion, verify agitator operation.
- Monthly: Calibrate, inspect bearings, check fasteners, and grease as required.
- End of season: Deep clean, touch up paint, replace worn parts, and store indoors.
Maintaining your spreader doesn’t have to be complicated: clean it, lubricate moving parts, inspect and replace worn components, and follow the manufacturer’s recommendations. With regular attention, your spreader will deliver consistent results and last for many seasons.
