2009 Mack GU713 6×4 Dump & Plow Truck is a severe-duty commercial vehicle built on the legendary Mack Granite vocational platform. Designed to handle intense municipal and commercial winter maintenance, this Class 8 workhorse features a heavy-duty 72,000 lbs. Gross Vehicle Weight Rating (GVWR) along with a specialized, highly functional integrated snow and ice management build.
Chassis & Performance Architecture
- The Platform: The Mack GU713 Granite features a severe-duty galvanized steel double frame. This provides maximum torsional stiffness to handle the tremendous leverage of a front plow and side wing.
- 6×4 Drivetrain: The 6×4 configuration utilizes tandem rear drive axles to ensure optimal traction in heavy snow, slush, and unpaved off-road conditions.
- Tire Footprint: The front steering axle runs 425/65R22.5 wide-base "super single" tires to float over soft surfaces and support the crushing weight of the Everest plow gear. The rear axles use heavy ply 12R24.5 traction tires, providing maximum ground clearance and exceptional biting edge power.
Mack MP7 Engine
- Powerhouse Specifications: The truck is driven by an 10.8-liter Mack MP7 inline-6 diesel engine. The MP7 engine typically produces between 325 and 405 Horsepower with up to 1,560 lb-ft of torque.
- Vocational Design: The MP7 is known for its excellent power-to-weight ratio. It features a single overhead camshaft, a variable geometry turbocharger (VGT), and ultra-durable wave pistons that optimize combustion while reducing soot buildup.
- Continuous Live Hydraulics: Typically configured with a front engine-mounted PTO (Power Take-Off), it ensures that the hydraulic pump runs continuously to power the snowplow and spreader regardless of whether the vehicle is stopped or shifting gears.
Allison 6-Speed Automatic Transmission
- Continuous Power Delivery: Paired with an Allison 6-speed automatic transmission (typically from the rugged Allison 4500 RDS series), this configuration provides uninterrupted torque to the drive wheels during gear changes. This prevents the momentum loss common with manual transmissions when plowing heavy snow drifts.
- Electronic Control: The push-button shift selector in the cab simplifies operation, reducing driver fatigue during grueling 12-to-24-hour winter shifts. It includes advanced electronic diagnostics to monitor transmission health under severe loads.
Everest Snow & Ice Equipment
- 12' One-Way Plow: The Everest 12-foot front plow is engineered to push heavy, wet winter snow efficiently out and to the right side of the roadway at speed.
- 11' Steel Wing: Mounted to the side of the chassis, the 11-foot steel snow wing allows the operator to clear the main lane and the road shoulder simultaneously or push back high snowbanks.
Dump Body & Harder Spreader System
- Everest 14' All-Season Dump Body: This multi-purpose 14-foot steel dump body functions as a standard heavy-duty aggregate hauler in the warmer months and transforms into an efficient salt/sand distributor in the winter.
- Harder Center Mount Spreader Chain: Instead of a traditional tailgate-mounted spinner, the Harder center-mount design utilizes a heavy-duty conveyor chain integrated into the floor of the dump body. This feeds material directly to the distributing apparatus, maintaining a lower, safer center of gravity during operation.
- Force America Electric-Over-Hydraulic Controls: Located safely inside the cab, this sophisticated electronic system manages the flow of the spreader chain and spinner speed independently. It allows the driver to adjust the exact material spread rate on the fly to match vehicle speed.
- Powered Tarp System: An electric roll tarp system protects the material payload (salt, sand, or gravel) from moisture and blowing wind and can be deployed quickly with the flip of an in-cab switch.
