Salt Spreaders and De-Icing

Spreading salt or sand is about getting the right amount on the right place. Too little does nothing, too much wastes material and eats your equipment.

Key points

Choose a spreader that fits your vehicle and your area.
Follow the product label and the spreader manual for settings.
Keep animals away from salt, and avoid overuse near water and soil.
Rinse and dry equipment to fight corrosion.
Shut down before clearing any clog.

What types of spreaders are there?

Spreaders come in a few styles. Tailgate and hopper units mount on a truck bed or hitch. Three-point hitch spreaders attach to a tractor. Walk-behind and ATV spreaders handle smaller lots and paths, and handheld units cover steps. A homestead with a short driveway and steps may never need more than a push spreader, while a ranch with a long, hilly lane and a gate where trucks stop may justify a truck-mounted unit.

Choose the style based on the area you cover, the vehicle you have and how often you spread.

Match the capacity to your area. A big hopper on a small lane means hauling extra weight, while a tiny unit on a long lot means constant refills. Ask a dealer about spread width too.

Walk-behind spreader for walkways
Handheld spreader for steps and small areas

What should you know about different materials?

De-icing materials include rock salt and other chemical blends, sand and grit. Each has trade-offs for cost, effectiveness at low temperatures, effect on concrete and plants, and impact on livestock and pets. Check each product's label and instructions, and ask your supplier about suitability.

Salt can harm animals if eaten in quantity, so keep livestock and pets away from treated areas and stored material. Runoff can affect soil, wells and ponds. Use only as much as needed.

Sand adds traction but does not melt ice, and it can clog drains and washes into ponds and ditches. Store any material under cover so it stays dry and flows from the hopper.

How do you set the spread rate?

Most spreaders have a gate or feed setting. Manufacturer instructions and the product label explain how to set and test it. A simple way to check is to spread over a tarp or a measured patch, then compare the results to the product guidance. Check the spreader for even distribution by watching the pattern, since worn spinners or bent vanes can throw more to one side.

Do not guess an amount. Conditions change with temperature, traffic and snow type, so adjust and watch the surface.

Write down your settings for each material in a small notebook in the cab. That saves guesswork next storm.

When should you spread?

Applying before a storm, called anti-icing, can keep ice from bonding to the surface. Applying after plowing helps with what remains. Salt works best when there is some moisture, and its effect weakens as temperatures drop, so it may not work at very low temperatures. Check the product label.

Plow first, then spread. Material under a deep layer of snow is wasted.

On gravel lanes, heavy salt use can loosen the surface and move fine stone. Light, targeted spreading at hills and corners often gives the best result.

How do you protect equipment from corrosion?

Salt eats metal. Rinse the spreader, hitch, truck underside and tractor after each use, then dry and grease moving parts. Touch up chipped paint, and use a rust-inhibiting coating if the manufacturer recommends it. Empty the hopper at season's end, because wet salt left inside cakes and rusts. Park a spreader with a loaded hopper inside a dry building or under cover, and never leave wet salt in it overnight if you can avoid it.

Check wiring and lighting connections for corrosion. A thin coat of dielectric grease on connectors helps in many cases, but follow the manual.

Grease pivots and chains

What safety points apply to spreading?

Spinning spreaders and augers can injure. Keep hands, clothing and hair clear, and shut down before clearing a clogged chute. Hitch PTO-driven units according to the manual and use guards. Wear eye protection and gloves when handling bagged material, since salt can irritate skin and eyes. If you use a PTO-driven spreader, check the shield and driveline before every season, because salt corrosion can seize shield bearings and leave the shaft exposed.

Spread slowly near walkways, parked cars and people. Hot sun and cold nights create refreezing, so watch for slick areas after melting.

Do not use a spreader with missing guards or a damaged chute. Replace worn parts with those the manufacturer specifies.

When is a contractor a better choice?

For large parking areas, public frontage or commercial properties, a contractor may carry insurance and equipment to meet local rules. Ask about liability, and talk to your insurance agent if visitors use your property. Check any local rules on salt use near wells or waterways.

A written service agreement helps if someone else spreads at your place. Ask what they use and where it goes, particularly near wells and barnyards.

When to get help: Ask your supplier and the product label about material and use, your dealer about hitch and PTO setup, and your insurance agent about liability for visitors or customers on icy ground. Check local rules on runoff and well protection.
