the manufacturer’s

guidelines for the inspection and maintenance schedules

Hydraulic fluid level on tow vehicle

Inspect tires for damage, proper inflation and that all lug nuts are in place and have not become loose

“STAY BACK 100 FEET” sign installed on rear of Tow Plow

All safety and warning labels are in place and legible


Inspections Continued

Visually inspect all hydraulic hoses and connectors for wear, damage, and leaks

Check all cables, chains, and sheaves for excessive wear and damage

Visually inspect all plow and wing units

Inspect cutting edge and shoes for excessive wear

Do not allow cutting edge to wear down into the mounting angle on the mold board


Inspections Continued

Inspect mounting arms for excessive rust, damage, cracks in welds or bent and broken sections

Inspect mounting holes on the arms and lugs for excessive wear

Mounting holes greater than 3/16” clearance are to be repaired

Dump air from the brake storage tanks on tow vehicle and the Tow Plow to remove excessive moisture and ensure that the system air pressure returns and does not leak

Add air brake drier to brake system to prevent air brake freezing during extremely cold weather



Grease all required components

All plow harness sheave nipples

All hydraulic pump drive shaft nipples

Front and rear tower sheaves and swivel blocks

Wing extension arm nipples

Front and rear tower guide tracks

All front harness pivot points

Check for loose or missing fasteners (nuts, bolts, cotter pins, lock rings, etc.)

Follow lubrication procedures for the Tow Plow and accessory equipment, such as spreaders

Refer to the owner’s manual for specific intervals


Hydraulic Set-up

Check hydraulic set-up prior to useSystem pressure should be 2300 psiSet hydraulic trims/flow for steering and mold board operationEnsure that Tow Plow response is:ConsistentSmoothNot too slow (may reduce reaction time for obstacles)Not too fast (could cause handling issues and damage)Include operator to ensure response is adequate to the operators preference and needs



Standard Configuration

Connection of hydraulics and liquid chemicals for spreaders and liquid tanks may vary

Refer to your experienced Tow Plow operator or District General Services for additional requirements

Attach Tow Plow to tow vehicle pintle hitch

Pintle receiver locked

Raise landing gear into full up position and handle stored in tow position

Air brake lines/glad hands connected (no leaks)

Connect Tow Plow safety chains

Connect plow lift hydraulic circuit

Connect steering hydraulic circuit

7 wire trailer plug installed and all Tow Plow lights operational

6 wire plug installed and all operator lights are operational

Inspect all lighting for damage and proper operation


Operational Preparation

Ensure brakes are released and not frozen

Gently pull against the Tow Plow with brakes released to ensure brakes are not frozen

Remove mold board lock pins

Stand behind mold board

Start at center pins working out

Installing mold board lock pins

Install for transport or when deployment is not required for extended duration

Stand behind mold board

Start with outside pins and work to center


Operational Check

Perform operational check prior to leaving maintenance facilitySteering (deployment and retraction)Steering wheels move freely through full stroke of activating cylinder while moving forwardMold board (up and down)Determine that the mold board moves freely from full up to full down


Deployment / Retraction

Visually check to ensure that the Tow Plow is clear of traffic


Do not deploy or retract while stopped to prevent damage to the Tow Plow’s tires

Full deployment is not required to operate

Deploy to any desired position

Always deploy to a position that will clear all obstacles

Deployment (steering) and mold board functions (up and down) can be performed at the same time if desired




Low Visibility

Always retract the Tow Plow in low visibility conditionsAlways have plenty of sight distance Give yourself time to react and retract the Tow Plow for:Stalled/stopped vehiclesPedestriansRoadway hazardsObstaclesGuard rails, bridge ends and signsWhen in doubt, pull in the Tow Plow



Use Tow Plow deployment to “steer” while negotiating tight turns

Left turns with right hand Tow Plows

Right turns with left hand Tow Plows

Avoid turns that require you to stop and back up

If retracted to tow position during turns, raise the mold board

Can be left in deployed position with mold board down and adjusted for obstacles to clear larger intersections


Steering Through Tight Turns


Pre-trip Inspection

Before each use:

Make sure that all nuts and bolts are in place and properly tightened

Make sure that all other fasteners are in place and are performing their specified function

Make sure all safety signs are in place, clean, and legible

Replace any damaged parts or excessively worn parts

Inspect for damage to any part of the plow mold board or push frame

Examples include broken or worn bolts or pins, cracked welds, bent sections, and/or excessive rusting

Inspect for damage to trip mechanisms, such as broken springs, cracked welds, and worn or broken bolts

Check all hoses for cuts, cracks, and leaks

Dump air from air brake reservoir to remove any moisture


Plowing Operations

Always try to position the Tow Plow in lanes that keep the plow farthest away from obstacles, such as guardrails, signs, etc.Position the Tow Plow based on type of operation and configuration of the plowsSingle operationPlow two lanes as best as possiblePlow center turn lanesGang operationHave enough plows to cover shoulder to shoulderUtilize single plow trucks for clearing shoulders and rampsHave single plow run shoulders next to guard rails


Gang Plowing

Try to position the crown of the road between the tow vehicle and the Tow Plow

For clearing first priority (high volume) routes, operational speeds should be within the following:

Safe for conditions present

Safe for traffic volume and conditions

Reduce spacing appropriately for limited visibility

Paced so that multiple gang trucks do not become separated

Spaced so that traffic may not pass between the gang plows


Starting Operations with a Gang

Communication is keyEnsure all operators know the procedures to be used Ensure that all operators know their position in the gangEnter traffic at speeds that are safe and allow the gang to stay together


Plowing Operations

Plowing heavy snow loads may require adjusting plow / truck positionSnow loads may suddenly decrease and allow the plow to skew back to it original position, such as clearing snow under bridges and overpassesTow may strike guardrail and other roadside devices when it returns to its normal position after the heavy snow load is releasedPlowing aggregate shouldersRaise mold board 2” to 4” above ground


Emergency Stopping

Maintain a safe distance from traffic in front of you

The Tow Plow is equipped with ABS braking system

Brake as you normally would

The procedure for stopping a trailer skid is:

Recognize the trailer skid by seeing it in your mirrors

Check mirrors anytime you brake hard to make sure the trailer is staying where it should be

Once the trailer swings out of your lane it is hard to prevent a jackknife

Stop using the brakes to get traction back

Do not use the hand brake (this will cause the trailer to continue to skid)

Once the wheels start to grip the road again, the trailer will start to straighten out and follow the tow vehicle

If the Tow Plow is deployed during a skid, leave in the deployed position



There are two groups of lighting on the Tow Plow:Work/warningOperational (DOT)Tow Plow lighting is connected to the truck via two separate trailer plugs:7 wire large plug for DOT vehicle lights6 wire plug for work and warning lights


Laser Guidance

Lasers can be used to determine Tow Plow position in relation to roadside obstacles

Can be helpful to determine Tow Plow position when fully extended

Mounted to the truck

Only represents full Tow Plow extension
