Why call it the parking lot killer?
A parking lot asks a plow to do two jobs: reach the snow near the building and cover the open pavement beyond it. The BOSS DRAG PRO 8′–16′ Hydraulic Folding Wing model puts a wide pulling blade behind the truck. Its hydraulic wings open the working width from eight feet to sixteen feet. That combination earns our “parking lot killer” nickname: a useful layout for a route with loading bays and open lots. It is an editorial description, not a BOSS quotation or a measured productivity claim. [1] [3]
The rear-pull workflow
BOSS describes backing into position, lowering the rear blade and pulling snow forward. Independent hydraulic wing control lets the operator change the configuration for the work area. Our planning takeaway: walk the lot as a sequence of pickup areas, clear travel paths and snow destinations. A wide blade needs a deliberate destination for the snow it gathers. Width alone does not establish pass count, clearing time or how much snow a particular truck can pull. [1] [3]
Order the exact model and complete mounting package
Keep RPL21616 on the enquiry. BOSS lists this version at 890 lb and categorizes its truck application as ¾- and 1-ton. That category is a starting point; it does not approve every truck in those classes. The manufacturer also warns that the product number may represent only part of a complete setup. Use the BOSS Product Selector and obtain confirmation for your actual vehicle and required mounting components. [1] [4]
Prepare a fitment brief before buying parts
Send the installer the truck year, make, model, drivetrain and configuration, plus photographs of the rear frame area and existing equipment. Include the vehicle rating labels, other carried equipment and the plow model/serial record. Ask for a written parts list and the applicable vehicle-specific rear-undercarriage instructions. These are our enquiry questions, not an assertion that a photographed hitch or existing bracket is approved. BOSS requires vehicle-maker recommendations and all axle and vehicle weight ratings to be respected. No ballast quantity can be selected from the blade width alone. [2] [4]
Make setup a documented handover
Have trained personnel perform installation. Use BOSS manual MSC22983 Rev B for the covered RPL21616 serial range, alongside the exact truck-mount instructions. Ask the installer to demonstrate attachment-pin retention, pushbeam-height and angle-of-attack checks, controller operation and protected harness routing. Keep the completed configuration and manual revisions with the truck. Torque, wiring and hydraulic connections belong to those applicable documents. [2]
Plan the lot before the first storm
BOSS advises agreeing on snow-pile locations, identifying hidden obstacles, keeping drains clear and protecting sightlines. Its parking-lot section prioritizes building and overhead-door areas before the open lot and recommends dividing large lots into sections. Our route-sheet suggestion: draw the loading bays, parked-car boundaries, pedestrian routes and final piles on one plan. Mark where there is sufficient room to use the full width and where the wings must stay tucked in. [2]
Daily checks that protect the next shift
The manual calls for daily checks of cylinders, fluid level, hydraulic lines/hoses, fasteners and retention hardware, cutting edges and the harness connector. It specifies monthly dielectric grease at connectors and annual hydraulic-fluid replacement. Record wear or damage for service before the next shift; a recurring symptom deserves a repair record rather than a guessed adjustment. Retract the wings for transport and before removal; follow the complete BOSS procedures. [2]
Bring the truck and the route into the same conversation
For an installation or transfer enquiry, ask Durand at Full Flow Hydraulics to review the exact rear-plow setup, the vehicle details and the work you expect it to do. Confirm scope, parts, timing and availability directly. This guide establishes neither stock nor authorized BOSS dealer status. A successful enquiry ends with the complete compatible package identified, not simply a decision to buy a sixteen-foot blade.
