Snow Plow Setup for Trucks and Tractors

A plow that is mounted wrong, or on a vehicle that cannot carry it, causes more trouble than the snow does. Setup is worth the hour.

Key points

Confirm in writing that your vehicle can carry the plow.
Follow the manufacturer's mounting and hydraulic instructions.
Do not overload axles and add traction the manual allows.
Check state rules for lighting and public roads.
Inspect cutting edges, pins and hoses each season.

Can your truck or tractor carry a plow?

Not every vehicle is built for the load. A plow adds weight to the front axle and puts side loads on the frame. Manufacturers specify which vehicles suit which plows, and truck makers often publish a plow prep package or front axle limits.

Check your owner's or operator's manual, and ask a plow dealer to confirm the combination in writing. For tractors, a loader frame or a front mount kit built for your model is the safe way. Do not weld up a home-made mount unless a qualified fabricator designs it.

Ask your insurance agent how a plow is treated on your policy, especially if you plow for neighbors or anyone else. Coverage varies, so ask before the first storm rather than after a claim.

Which plow type suits which job?

Straight blades push snow forward and are common on tractors with a loader. Angling plows move snow to the side and are favored for long drives. V-plows and wing designs can handle drifts and wide areas. On a truck, a standard mount with a hydraulic angle control is common.

Pick the width based on lane width and the vehicle's size. A plow that is too wide can hit gate posts, mailboxes and fences.

A tractor with a loader may do better with a snow pusher or box attachment than a blade, since it stacks snow in front rather than casting it aside. Check what the loader and the manual allow.

How do you set up the mount and hydraulics?

Follow the plow manufacturer's instructions for mounting. Check that hardware is the right grade, pins are secure, and hydraulic hoses are routed away from pinch points and heat. Use the fluid type the manual specifies.

Cycle every function slowly before heading out. Look for leaks and make sure the plow lifts, lowers and angles smoothly.

Mark the plow edges with tall stakes or reflective markers so you can see the corners in a whiteout. Ask a dealer about options approved for your plow.

Inspect mounting hardware before each season
Use specified hydraulic fluid
Check for hose rubbing and fittings that weep
Test lift, angle and lower functions with no one near the plow

What about traction and weight?

Plowing on slick ground takes traction. Add ballast the manufacturer allows, or use chains or snow tires. A heavy plow on a light truck can overload the front axle, so ask a dealer about suspension upgrades or limits. Do not exceed the vehicle's rated axle or gross weight.

Tractors do best with proper ballast and tires, and with a cab that keeps you comfortable for a long shift.

Check the tire condition and the front-end parts before the season, since plowing puts extra load on steering and suspension. Worn ball joints or tie rods are a safety problem.

Do you need lights and markings?

A plow can block headlights. Many setups use plow-mounted lights or a lighting kit that is approved for the vehicle. Rules for lighting, flashing lights and marking, plus any restrictions on plowing public roads, vary by state. Check with your state DOT, highway patrol or department of motor vehicles.

Do not plow public roads without confirming what is legal.

If you are plowing a shared road or an association lane, ask the board or the county what they allow, and check any insurance requirements.

How do you plow safely?

Start with a quick walk of the area and mark curbs, hydrants, stones and ditch edges. Take it slow when you hit the pile. Raise the plow when backing up unless the design allows otherwise, and look behind you before reversing. Do not plow near people or children.

Keep your seat belt on, and avoid steep slopes where tipping is a risk. Do not exceed the speeds in the manual. Watch for overhead wires when raising a plow near eaves or low lines.

Take regular breaks. Long plowing shifts in the dark are tiring, and tiredness leads to hitting fixed objects.

What upkeep does a plow need?

Check the cutting edge and replace it when worn. Inspect shoes, pins, springs and the trip mechanism if equipped. At the end of the season, wash off salt, touch up rust, and store the plow on a stand. Grease fittings as the manual describes.

For major hydraulic or structural repairs, see a qualified shop.

When to get help: Use a plow dealer or the vehicle's dealer service department to confirm fit and weight limits, and a qualified shop for hydraulic and structural repairs. Check lighting and road-use rules with your state DOT or highway patrol.
