When winter rolls in with its icy grip, it’s easy to forget about your horse trailer—after all, it’s not going anywhere anytime soon, right? But neglecting your trailer during the off-season can lead to costly repairs, safety hazards, and a whole lot of stress when spring finally arrives.
That’s why winter is the perfect time to give your trailer the attention it deserves. Think of it as tucking your trailer in for a cozy, damage-free nap until riding season returns. Here’s how to do it right.
1. Start with a Thorough Inspection
Before you think about covering or storing the trailer, do a complete walk-around:
-
Check tire condition and pressure. Cold weather deflates tires quickly and can cause cracking if they’re not in good shape.
-
Inspect the floor, whether wood or aluminum. Look for signs of rot, rust, or wear.
-
Test the lights and wiring. Winter moisture can wreak havoc on connections and bulbs.
-
Look underneath. Salt and road grime can cause rust if left unchecked.
2. Clean It Like You Mean It
A deep clean is your trailer’s best defense against winter damage:
-
Remove floor mats and wash them separately.
-
Sweep out old hay, dirt, and bedding.
-
Use a mild detergent and hose down the interior, including the walls and floor.
-
Dry everything thoroughly before putting it back together.
Leaving moisture or organic debris in the trailer can lead to rust, mold, and a serious mess when you’re ready to use it again.
3. Lubricate Moving Parts
Cold temperatures can stiffen up metal parts, making doors harder to open and increasing wear on components:
-
Apply a weather-resistant grease or spray lubricant to hinges, latches, door handles, and the hitch mechanism.
-
Check your brake components if applicable, and lubricate where needed.
Regular lubrication now can prevent frustrating breakdowns later.
4. Protect the Exterior
If your trailer will be stored outside:
-
Wash and wax the exterior to protect the finish.
-
Apply a protective coating to metal areas prone to rust.
-
Consider using a breathable, weatherproof trailer cover—but never wrap it too tightly or use plastic tarps that trap moisture.
If possible, park on gravel or concrete, not grass or dirt, to reduce moisture from the ground.
5. Block Out the Critters
Mice and other rodents love trailers in the winter. They’re warm, dry, and full of places to nest.
-
Seal small openings with steel wool or rodent-proof foam.
-
Avoid leaving food or treats inside.
-
Consider placing natural repellents like peppermint oil or commercial deterrents in the tack and horse areas.
6. Battery and Brakes
If your trailer has a battery-powered brake system or interior lighting:
-
Disconnect and remove the battery if possible.
-
Store it somewhere warm and dry, and recharge it every few weeks to maintain its lifespan.
Final Thoughts
Horse trailer winter maintenance isn’t the most glamorous task, but it’s one of the smartest things you can do to protect your equipment—and your horse’s safety. Taking just a few hours to inspect, clean, and prep your trailer now can save you time, money, and headaches come spring.
Your horse deserves a smooth, safe ride. And your trailer? It deserves some winter TLC.
