A Guide to Getting Your Agricultural Machinery Ready for the Cold Months
As the harvest wraps up and those first harsh winter storms begin to roll in, farmers across the country are starting to switch from active fieldwork to putting their equipment into a dormant state. For those of us who live and work in cold climates, the winter months can be a real challenge for keeping our machinery in good working order.
Without a solid plan in place, your tractors, combines, and other farm equipment are going to be vulnerable to two of the biggest enemies out there: rust and corrosion. When temperatures drop and the first snows start to fall, the fluids and metal components of your equipment are put under a lot of stress, which can lead to some pretty pricey repairs come springtime. To help you get a head start on winter prep, we're putting together a comprehensive guide with tips for keeping your equipment in top shape. We'll also cover best practices for long-term storage.
The Science Behind Winter Damage: Rust and Corrosion
To really protect your machines, it is crucial to understand how moisture and ice interact with metal. Rust isn't just something that's aesthetically unpleasant - it's a serious chemical reaction that can compromise the integrity of your equipment and diminish its power, making understanding rust especially crucial. Corrosion happens when oxygen and moisture meet metal surfaces, and if you live in an area where they use a lot of salt or other chemicals on the roads during the winter months, that process is only accelerated.
-
Oxidation: This is the primary cause of rust on exposed steel surfaces - and it's something you need to be on top of if you want to prevent it from becoming a big problem.
-
Galvanic Corrosion: This is another major culprit - and it happens when electronics and different metal types are stored in damp conditions.
-
Pitting: This type of corrosion can ruin the texture of cylinder rods and bearings.
Getting your equipment clean before storing it is a key step in preventing rust and corrosion and ensuring proper protection. Debris, mud, and leftover plant matter can all trap moisture against the metal, creating a perfect environment for corrosion to take hold. Before putting any vehicle into storage, make sure to give it a good pressure wash to keep the finish and internal components in good shape.
Step 1: Fuel System and Engine Storage
One of the most important things to do before you start storing your agricultural machinery for the off-season is to get your diesel and gasoline supplies in order, which may include purchasing new fuel. When you leave fuel sitting around for too long, it can start to degrade and form gums and varnishes that can clog your injectors.
-
Fuel stabilizer: Add a high-quality fuel stabilizer to the tank before making the final run of the engine.
-
Top off the tank: Make sure to fill the tank to the brim before putting the equipment into storage. This leaves no room for air to get in and cause condensation.
-
Oil change: Used oil is pretty acidic, so it's a good idea to replace it with some fresh oil and a new filter before putting the equipment into storage.
-
Drain the separators: If your tractors have water separators, make sure to drain them to prevent ice from cracking the housings.
For gas-powered machines, you want to make sure the engine runs long enough to perform properly for the fuel stabilizer to reach the carburetors. This is a simple task, but it'll help prevent the fuel from turning into a thick sludge during the winter months.
Step 2: Battery Maintenance and Electronics
The battery is often the most neglected component of farm equipment care - but in cold weather, its chemistry changes, which can slow its performance and eventually lead to a total failure, especially regarding its reliance on electricity.
-
Clean the terminals: Use a wire brush to clean off any corrosion from the battery posts.
-
Maintain the charge: Use a battery tender or trickle charger to keep the voltage at a healthy level.
-
Temperature control: If you don't have a heated shop, your best bet is to remove the battery and store it in a climate-controlled space.
-
Protect electronics: Modern agricultural equipment is full of electronics, so make sure all control panels and monitors are kept free of moisture.
If a battery is left discharged in freezing temperatures, the electrolyte can freeze and crack the case. As part of your service plan, make it a point to check the battery voltage on all your equipment at least once a month.
Step 3: Protecting Exterior Surfaces and Tires
Rust doesn't just attack the engine - it targets every exposed inch of your equipment. Many farmers are now using specialized devices and coatings to create a barrier against the elements.
-
Rust prevention sprays: Apply a wax-based or oil-based rust inhibitor to all exposed cylinder rods and unpainted metal.
-
Tire care: Clean the tires and inspect for wear. Store the vehicle on blocks or a hard surface to prevent the tires from sinking into the ground and rotting.
-
Give Everything a Grease: Do a full grease job on all zerks, getting out the moisture and old gunk that's been stuck in the joints.
-
Clean Out the Interior: If you've got a tractor cab or a car that spends time on the farm, vacuum up any food scraps that might be attracting rodents looking to ride out the winter in a warm spot.
Rodents are a major thorn in farmers' sides, especially when they get into electronics and wiring. Some folks use blankets or gizmos that emit high-frequency sounds to keep pests at bay, while being aware of other potential traps. But let's be real - putting refrigerators and food storage near your trucks is just asking for trouble. It's like inviting the pests into your shed.
Step 4: Your Cooling Systems and Fluids
Even when your machine isn't running, the service and health of your cooling system is super important, especially as you prepare for next season's crops.
-
Check Your Antifreeze: Use a hydrometer to see if your coolant is rated for the cold temps in your area. If not, replace it - don't skip this step!
-
Inspect Your Hoses: Take a close look for any signs of cracks or leaks. Cold weather does a number on rubber, so now's the time to fix and replace any worn parts.
-
Hydraulic Fluid: Check the oil level and look for that telltale milky texture, which means your fluid's got moisture contamination - yuck!
Step 5: Where You Store Your Gear Matters
Just as important as how you service your equipment is where you store your agricultural machinery. Yeah, a climate-controlled garage would be ideal, but let's face it, that's not usually an option for big combine units or wide tractors; you may need to consider other options .
-
The Shed: Make sure the roof doesn't leak snow or rain onto the electronics - you don't want that kind of damage. Good insulation can help with rapid temperature swings.
-
Airflow: Even in a cold shed, you need some air movement to prevent moisture from condensing on cold metal surfaces.
-
Lights: Make sure your storage area's got working lights so you can give your fleet a good once-over throughout the winter.
-
Floor Surface: If possible, avoid parking on bare grass - a gravel or concrete floor is way better for protecting your undercarriage from corrosion.
Pro-Tips for Winter Storage
-
Engine Care: Always run the engine for 10-15 minutes after adding fuel stabilizer to ensure it reaches the fuel injectors or carburetor.
-
Battery Health: If storing in a location with freezing temperatures, consider removing the battery entirely and keeping it on a wooden surface in a temperature-controlled area.
-
Hydraulic Protection: Use a high-quality rust prevention spray specifically designed for agricultural use to ensure the coating doesn't degrade the seals when the cylinders are cycled in the spring.
Get a Pro to Check It Out and Plan Ahead
The manufacturers of your agricultural equipment will have a winterization checklist in their manuals - don't be a cheapskate, follow those steps as discussed in this article to regularly inspect and keep your equipment's power warranty intact. And don't even get me started on farm safety organizations recommending a monthly walk-around to check for pest damage or fluid leaks - do that too.
If you see rust starting to creep into a fender or frame corner, address it pronto. Clean it up, slap on a professional primer - or better yet, bust out some pro-grade ceramic coatings that'll give your most expensive tractors years of protection.
