Winter storage of agricultural machinery – 5 mistakes to avoid | GĄSKA
Winter is a time when most agricultural machines remain unused — but that does not mean they can be left without care. Improper winter storage of agricultural machinery is a common cause of costly repairs, accelerated corrosion, damage to hydraulic systems, and problems with starting in spring. For a farmer, every day of downtime means losses — therefore, proper preparation of equipment for winter and the use of appropriate conservation measures is an investment that pays off quickly. In this guide, GĄSKA highlights 5 of the most common mistakes and practical solutions that reduce the risk of failures and extend the lifespan of machines.
Proper winter storage of agricultural machinery: why is it important?
Winter storage of agricultural machinery is not just placing them in a barn. It is an entire process that includes cleaning, conservation, drying, securing fuel, hydraulic, and electrical systems, and proper storage.
The main goal is protection against:
• corrosion caused by moisture and salt,
• damage to rubber and plastic components (hardening, cracking),
• freezing of fluids (cooling, hydraulics),
• battery discharge,
• degradation of oils and fuel.
The consequences of neglect are concrete: downtime during key moments of the season, costly repairs of bearings, hydraulic pumps, or engines, as well as reduced equipment lifespan. Pre-winter servicing and the use of appropriate protective agents (e.g., anti-corrosion preparations, fuel stabilizers, winter oils) is a standard that protects the value of the investment.
5 key mistakes and how to avoid them
Below we describe the five most common mistakes made during winter storage of agricultural machinery — each mistake is accompanied by practical solutions.
Mistake 1 — Leaving dirt and organic residue on the machine
Why it is a problem:
Mud, manure, and plant debris retain moisture and accelerate corrosion, contaminate systems, and promote fungal growth.
How to avoid it:
Thorough washing and drying before storage — pay attention to the underside of the frame, bearings, and hard-to-reach areas. Use a pressure washer with a degreasing solvent for oily dirt, then apply an anti-corrosion preparation to exposed metal parts.
Mistake 2 — Insufficient protection of the fuel and oil system
Why it is a problem:
Old fuel can “solidify,” sediment may form, and oil can lose its properties. This makes starting difficult and accelerates wear of engine components.
How to avoid it:
Fill the fuel tank (less air = less condensation), add a fuel stabilizer, replace the oil with one compliant with the manufacturer’s recommendations if such replacement is advised before storage, and replace the fuel and oil filters. Ensure additional filters are in place if the downtime is long.
Mistake 3 — Ignoring the hydraulic system and bearing lubrication
Why it is a problem:
Air and moisture in the hydraulic system lead to corrosion and contamination; improper lubrication of bearings shortens their service life.
How to avoid it:
Drain or replace hydraulic fluids with those offering better winter performance, and lubricate all grease fittings before storage according to the manual (extensive use of long-lasting lubricants). Disconnect hydraulic loads and position cylinders safely.
Mistake 4 — Improper storage of batteries and the electrical system
Why it is a problem:
Discharged batteries lose capacity faster; moisture and frost can damage installations.
How to avoid it:
Fully charge the battery and, if possible, store it at a controlled temperature (e.g., in a garage). Disconnect cables for longer downtime, apply protective anti-corrosion products to terminals, and check wire insulation and electrical connections.
Mistake 5 — Storing equipment outdoors or on unsuitable surfaces
Why it is a problem:
Storage on soil or moist ground accelerates corrosion from below and may lead to issues with tracks, tires, and the frame. Outdoor exposure also increases the risk of mechanical damage and theft.
How to avoid it:
Store machines under a roof or use tight tarpaulins on a supporting structure (do not wrap tightly with foil — ventilation is necessary). Ensure the ground is dry and hardened; use pads or blocks to minimize contact with the soil. Secure machines from unauthorized access and regularly check the condition of covers.
How to identify the quality of conservation products and where to find them?
A good conservation product is one that has documented agricultural applications, is resistant to low temperatures, and forms a durable anti-corrosion barrier. When making a selection, pay attention to:
• the manufacturer’s reputation and references from agricultural service providers,
• the intended use of the product (e.g., chain preparation, anti-corrosion spray, long-lasting grease),
• technical parameters (operating temperature range, material compatibility),
• recommendations from the machine’s manufacturer (not all products are compatible).
