Pre-Season Snowmobile Checklist

Get Trail-Ready

Nothing kills the excitement of the first real snowfall like a sled that won't start, a trailer with dead lights, or a dealer telling you parts are three weeks out. Every fall, the riders who are first on the trail are the ones who did their homework in September and October.

Whether you ride a Polaris, an Arctic Cat or something else, work through these 12 steps before the snow flies. Always follow your owner's manual for model-specific specs and service intervals.

Part 1: Get the Sled Ready

1. Deal with old fuel

Gas that sat all summer can go stale, especially if it wasn't stabilized. If the tank smells varnishy or the sled ran rough last spring, drain it and start with fresh, high-quality fuel. Check fuel lines for cracks while you're there.

2. Test the battery

If your sled has a battery, charge it fully and test it. Batteries that sat on the shelf all summer without a maintainer often won't survive a cold morning. Clean corrosion off the terminals.

3. Inspect the drive belt

Look for glazing, cracks, frayed edges or missing cogs. Measure the width against your manual's spec. Replace it if it's worn, and pack a spare belt and the tool to change it. A snapped belt 20 miles from the truck ruins a day fast.

4. Check the track and hyfax

Run your hands along the track for torn lugs, missing studs or damaged clips. Check track tension and alignment per your manual. Inspect the slide rails (hyfax) for heavy wear, since worn slides can damage the rails.

5. Look over the skis and carbides

Worn carbides make steering vague and sketchy on hardpack and ice. Replace them if they're rounded off, and check ski spindles and bushings for play.

6. Grease the suspension

Hit every grease fitting on the front and rear suspension until fresh grease pushes out. Check shocks for leaks and make sure springs and limiter straps are in good shape.

Part 2: Engine, Trailer, Gear and Paperwork

7. Check fluids and plugs

Top off or change oil (two-stroke injection oil or four-stroke engine oil), chaincase oil and coolant per your manual. Pull the spark plugs and replace them if they're fouled or worn, and carry a spare set.

8. Test lights, controls and safety switches

Check headlights, brake lights and hand and thumb warmers. Make sure the throttle snaps back cleanly, the brakes feel firm, and the tether and kill switch both shut the engine down.

9. Get the trailer road-ready

The trailer sat all summer too. Check tire pressure and tread, repack or grease wheel bearings, test all lights and wiring, and inspect tie-downs, the ramp and the coupler. Salt season is hard on trailers, so start clean.

10. Rebuild your trail kit

Restock what you used last season: spare belt, plugs, basic tools, tow strap, first aid kit, headlamp, fire starter and emergency blanket. A compact shovel earns its spot the first time you're stuck in deep snow.

11. Check your riding gear

Try on everything. Look for cracked helmet shells, fogging visors, torn gloves, dead heated gear and boots that leak. Replace your helmet if it took a hard hit or is past the manufacturer's recommended age.

12. Sort out registration, trail passes and safety training

Renew your registration and buy your trail pass or permit before the season opens. Some states now sell next season's passes as early as September. Check whether you, or a younger rider in your family, needs a state snowmobile safety certificate before riding. See our guide to the best snowmobile trails in Wisconsin, Minnesota and Michigan for each state's pass costs.
