Why does winterizing equipment matter?
Water expands when it freezes, and it can crack engine blocks, pump housings, hoses and fittings. Old fuel gums up carburetors, damp batteries lose capacity and rodents move into any warm, quiet corner of a machine.
Most of the damage is invisible until spring, when repair is more expensive and parts are in demand. An hour of preparation per machine in the fall is far cheaper than a shop visit in the busy season.
Start the job early, while days are still mild. Cold fingers and short daylight lead to skipped steps, and parts that you need may take weeks to arrive once everyone else is ordering too.
What should I do about fluids and fuel?
Check coolant protection with the tester your dealer recommends, and ask what mix your engine requires. Fresh oil and filters before storage remove acids and moisture that sit in used oil. Follow the manual for hydraulic and transmission fluid.
For fuel, follow the maker's guidance. Some recommend a full tank with a stabilizer made for the engine, others recommend running it nearly dry. Ask your dealer if the manual is not clear, and dispose of old fuel through your local waste program.
Never guess at coolant type or mix. Different engines call for different coolants, and mixing them can cause problems. The manual and your dealer can tell you what yours needs and how often to replace it.
- Coolant strength checked and topped up as directed
- Fresh oil and filters
- Fuel treated or drained per the maker's advice
- Grease fittings serviced
How do I protect batteries?
Clean the terminals, check the charge and either remove the battery to a cool, dry place off bare concrete or connect a maintainer designed for that battery type. A discharged battery can freeze and crack in cold weather.
Wear eye protection and gloves when handling batteries, and keep sparks and flames away. Charge in a ventilated area, and follow the maker's instructions on charging.
Store a removed battery upright and away from heat sources, children and metal objects that could short the terminals. Check the charge every month or so through the winter, as the maker advises.
What about water systems, pumps and hoses?
Drain and disconnect hoses, pressure washers, sprayers, pumps and any machine with a water reservoir, and store them where they will not freeze. Open drains and valves so no water stays trapped in low spots.
Look at outdoor hydrants and waterers as well. Make sure frost-proof hydrants drain properly after each use and that hoses are not left attached. Ask a plumber or your extension office about draining systems unique to your setup.
If you are unsure how to drain a particular pump or sprayer, look up the model's manual online by name and number, or call the dealer before the first hard freeze.
How do I keep rodents and moisture out?
Mice nest in air cleaners, seats and wiring and can chew insulation and hoses. Clean machines of seed, feed and residue, seal openings you can, and set traps or deterrents outside the machine rather than poisons near stored feed or animals.
Cover openings such as exhaust pipes and air intakes as the manual allows, and remember to remove covers before starting in spring. Leave a visible reminder tag on the steering wheel.
Check that the shed or barn itself is sound. A leaking roof over stored equipment undoes much of your preparation, so fix it before the machines move in.
What about cold-weather use?
If you must run equipment in winter, warm it up gently, use the oil and fuel grade recommended for cold weather and watch for ice on controls, steps and hitches. Block heaters and battery warmers need the correct cords and a safe, grounded power supply.
Have a licensed electrician check circuits that power block heaters. Frayed cords, overloaded extensions and space heaters in storage buildings cause fires.
Allow extra time for cold starts, and never use starting fluids or open flames near a cold engine unless the manual specifically permits it, since those can cause fires and engine damage.
How do I keep track of it all?
Make a one-page list for each machine and tape it inside the shop or put it in a binder. Note the tasks, dates, parts needed and any problems you noticed during the season, so you can schedule repairs before spring.
Photograph the hour meters and any worn parts before you put machines away. In spring the photos show what you saw in the fall and help you order the right parts at the right time.
Share the list with anyone else who uses the machines, so a hired hand or family member does not start a machine you set up for storage.
Key takeaways
- Fall preparation is cheaper than spring repair.
- Protect coolant, fuel and batteries per the maker's instructions.
- Drain water from pumps, hoses and sprayers, and keep rodents out.
- Keep a written list and photos for each machine.
