Snow Plow Equipment Readiness Checklist for Ohio

If you’ve ever had a plow drop dead in the middle of a 3 a.m. push with eight inches on the ground and four properties still to clear, you only need that to happen one time before pre-season prep becomes a religion. Mine did, on a Western plow in February 2019, on a commercial lot in Grove City. Solenoid went on the angle valve. I spent the rest of that storm shoveling and angling by hand. The next October I built the checklist I still run every November.

This is what I work through on every truck and skid-steer attachment in the Lawn Harmony fleet before the first plowable event. If you’re a homeowner with a small ATV plow or a contractor running a fleet of straight blades, the checklist scales the same.

What should I check on my snow plow before the first storm?

Pressure-test the hydraulics, change the fluid if it’s been more than two seasons, inspect and replace the cutting edge if it’s worn past the wear bar, exercise every angle and lift function 10 cycles, verify all plow and truck lights work, and grease every pivot point. If you do nothing else, do those six things. The rest of this checklist is what separates a truck that finishes the route from one that needs a tow at 4 a.m.

OSU Extension and the Ohio Department of Transportation both publish winter equipment guidance aimed at municipal crews, and the core message in both documents is that 80 percent of mid-storm plow failures are preventable with a 30-minute pre-season inspection. I believe it. Every failure I’ve had was something I could have caught in the driveway.

Hydraulic system: fluid, hoses, and seals

Plow hydraulic fluid is not engine oil and it is not power steering fluid. It’s a low-viscosity, low-pour-point hydraulic oil designed to stay liquid at zero degrees. Western, Boss, Fisher, and Meyer all spec slightly different fluids, and mixing them is the fastest way to gum up a pump.

My routine in November:

• Pull the reservoir cap and check fluid level with the plow fully lowered (level should be at the fill mark, not over)
• If the fluid is dark, milky, or has visible water suspension, drain and refill
• Inspect every hose for cracks, bulges, soft spots, or weeping at the crimp
• Bench-cycle the plow with the truck running 10 full angles left, 10 full angles right, 10 full lifts
• Listen for cavitation noise from the pump and watch for slow response on any function

On a Boss V-plow I run on the F-250, last November I caught a hairline crack in the driver-side wing angle hose during the bench cycle. Replaced it in the driveway in 20 minutes. That hose would have blown on the first heavy push and dumped two quarts of fluid on a Circleville cul-de-sac.

Cutting edge and trip springs

The cutting edge is the part that meets the pavement, and it wears faster than people expect. A standard 1/2-inch by 6-inch carbon steel edge on a 7.5-foot straight blade typically lasts one full Central Ohio season on a residential route, or about half a season on a commercial lot with a lot of curb work.

Check the edge for:

• Uniform wear (one corner more worn than the other means your plow shoes are off)
• Wear past the upper wear bar or punch marks (replace immediately)
• Loose or missing carriage bolts
• Cracks or chips at the corners

Trip springs on a trip-edge or full-trip moldboard need to be checked for free length and tension. A trip spring that has lost half an inch of free length has lost most of its rebound force and will let the blade plant face-first into a curb or a manhole cover.

I keep a spare cutting edge and a full set of carriage bolts in the shop from October through April. The local Western dealer in Columbus runs out by mid-January every year. Don’t be the guy calling around at 6 a.m. looking for hardware.

Lights, wiring, and the plow harness

Plow lights take more abuse than any other component on the truck. Vibration, salt, brine, and the occasional snowbank collision kill bulbs and corrode connectors. I have replaced enough plow light harnesses to retire on the parts markup if I sold them at full retail.

Pre-season light check:

• All four plow lights on and aimed correctly (low and high beam)
• Truck headlights cut out when plow lights are active
• All marker lights on the truck functional
• Brake, tail, turn, and reverse lights all working
• Trailer plug and seven-pin connector clean and weatherproofed
• Backup alarm functional (required on most commercial contracts)

I dielectric grease every plug on every truck in October. Costs me about $4 a truck and saves a guaranteed corrosion call mid-season. On a Lancaster account where I push two commercial lots back-to-back at midnight, blown plow lights mean I’m done for the night. That’s $600 in lost revenue per truck per missed event.

Grease everything that moves

Pivot pins, lift cylinders, hinge bolts, A-frame pins, headgear pivots. If it pivots, it gets grease. I use a marine-grade synthetic grease that holds up to salt brine better than the cheap lithium stuff. Two pumps per zerk, then exercise the joint to push grease into the bushing.

On a Pickerington plow client’s driveway last winter I watched a competing contractor’s plow hinge bind so badly mid-storm he couldn’t angle the blade. The pin was bone dry. He finished that driveway in straight-blade-only mode and lost two corners’ worth of work. Grease is cheap.

The truck itself

The plow is only half the rig. The truck has to push it, and a worn front end will kill your plowing performance faster than any blade issue.

Truck pre-season:

• Front shocks and ball joints inspected (worn ball joints under plow load is dangerous)
• Tire tread above 6/32 on the drive wheels and matched side to side
• Battery load-tested (cold cranking matters in 5-degree mornings)
• Alternator output verified under load (plow + lights + heater pulls hard)
• Cooling system flushed if more than three years old
• Wiper blades and washer fluid (rated to -20F for Ohio)
• Heater and defroster confirmed working before the first cold morning
• Emergency kit: blanket, snacks, charger, flashlight, tow strap, flares, shovel

I run a dedicated set of dedicated snow tires on the plow trucks from mid-November to mid-March. The cost works out to about $400 a year amortized over the tire life, and the traction difference on an unplowed Circleville back street at 2 a.m. pays for itself the first storm.

Skid-steer and tractor attachments

For commercial properties I run snow pushers and pull-behind brooms on a skid-steer. The same principles apply: hydraulic fluid, cutting edge, pivot pins, lights, and tire chains if you’re running a tracked or rubber-tire machine on ice.

Pull-behind salt spreaders on the trucks need their own October prep:

• Spinner motor brushes inspected
• Chain or auger lubed and free
• Hopper screen in place and clear
• Vibrator function tested
• Controller calibrated and wiring sealed
• Tarp or cover for the hopper

A spreader that jams 30 minutes into a salting route is worse than no spreader at all. You’re committed to the route, the lot is iced, and you’re shoveling rock salt by hand.

Documentation, contracts, and communication

The non-equipment side of plow readiness gets ignored every year and costs people their good clients. Before the first storm:

• All plow contracts signed and on file
• Property maps drawn with hazards marked
• Trigger depths agreed in writing (most of my Lancaster commercial accounts trigger at 2 inches)
• After-hours contact for every property manager confirmed
• Salt and deicer pricing locked with your supplier
• Per-event vs seasonal pricing clear with every client

I’ll cover snow event communication for property managers in a dedicated post this week. For now, the rule is: if it isn’t in writing before December 15, it isn’t a contract.

Common pre-season mistakes I see

• Skipping the hydraulic fluid change because “it still looks clear”
• Running last year’s cutting edge “one more season”
• Not bench-cycling the plow until the first storm
• Leaving plow lights aimed where they were last March (vibration moves them)
• Forgetting the truck’s tire pressure goes down 1 psi per 10 degrees of temperature drop
• No spare parts in the truck (cutting edge, hoses, bulbs, fuses, solenoid)

The spare parts one is the biggest separator between contractors who finish their routes and contractors who don’t.
