The Oshkosh Municipal Patrol Truck (MPT) - builds on the Oshkosh legacy of outstanding snow removal vehicles. Unlike many commercial vehicles that are adapted to plow snow, the MPT-Series is engineered and built specifically to handle severe-duty snow removal.
A smaller, more economical version of our legendary P-Series, the MPT-Series 4x4 chassis is built from the ground up as an all-wheel-drive truck, unlike mass-produced commercial vehicles that are converted off the assembly line. It has all the strength, durability, reliability and value you’ve come to expect from over 50 years of Oshkosh expertise.
SMALLER SIZE, BETTER HANDLING.
The MPT-Series has a 118" bumper-to-back-of-cab length—that’s 13" shorter than its P-Series big brother and results in excellent handling. Overall height is 111" for easy cab accessibility.
LEGENDARY ALL-WHEELDRIVE COMPONENTS.
Superior durability comes from the same road-proven transfer case as the larger P-Series, plus the Oshkosh steering drive axle with closed-wheel end design and heat-treated alloy axle shafts. The steering axle’s adjustable tapered-roller trunnion bearings are engineered to easily handle the side loads encountered under severe snow-removal conditions.
STRONG SINGLE-CHANNEL FRAME.
The solid, single-channel 12-3/8" frame with 110,000 psi yield strength and an RBM of 2,733,500 in. lbs. per rail has deep section cross members secured to it, specifically to withstand the punishing side thrust of snow removal.
ERGONOMICALLY-DESIGNED, EFFICIENT DASHBOARD.
Easy-to-reach controls are logically located on an instrument panel that’s easy to remove for repair or replacement of gauges. A convenient touch-pad gear selector (automatic transmission) is at the driver’s fingertips. Side-window defrosters are integrated into the dash, and reset-type circuit breakers are easily accessed from a panel on the dash’s right side.
COMFORTABLE, ROOMY CAB.
An air-ride driver’s seat delivers maximum comfort, while a flat floor provides comfortable accelerator and brake pedal locations, and makes cleaning the cab very simple.
SMOOTHER RIDE, LESS COMPONENT STRAIN.
The MPT-Series allows full front suspension travel, thanks to our from the-ground-up design emphasis. That same dedicated design provides greater clearance from the engine oil pan to the front axle bowl than competitive models and conversions. That means a smoother ride and less strain on major components over time.
EXCELLENT VISIBILITY.
Safety and productivity are enhanced with a reverse-slope windshield, top-mounted windshield wipers, and optional side-window wipers. All dramatically reduce snow and ice build up, and help prevent wiper damage. Plus, a short hood means superior visibility from the driver’s seat.
ATTACHMENTS ARE EASILY ADDED.
Plows, dump spreaders and other equipment can be added quickly, without having to first move other
components. Number- and color coded wiring harnesses and weatherproof electrical connectors assure easy identification and repair, as well as easy installation of dealer-installed lighting.
PROVEN CAB-MOUNTING SYSTEM.
We use a three-point system of attaching the cab to the vehicle with rubber mount cushions, so shocks, vibrations and torsional strains from roads are absorbed without transferring them to the cab.
SUPERIOR ENGINE-COOLING SYSTEM.
Our heavy-duty fin-and-tube-type radiator has a full 1,000 square inches of cooling area. Its steel frame and tanks are bolted to a copper core for superior strength and longevity. Mounted above the frame rails, the radiator location allows room for easy installation of a crankshaft-driven PTO.
FENDERS AND HOOD MAKE ACCESS EASY.
Engine access and equipment mounting are a cinch, thanks to cutaway fenders and a butterfly hood. Daily oil checks can be done from the ground through a small hatch in the hood. And the easy-to-remove fenders give quick, full accessibility for more extensive engine maintenance.
