About this file
This is a specification document for RFP 210000002261 issued by Department 591 for the procurement of one heavy-duty snow blower attachment for wheel loader equipment. The specification details a two-stage rotary snow blower unit designed to attach to a 2021 Caterpillar 950M wheel loader via a Fusion Quick Coupler series bolt-on hitch. The equipment is referenced against the Wausau SNOGO Model MP Rotary Snow Blower as the baseline specification. Key operational parameters include an operating capacity of 1,800 to 2,000 tons per hour, a snow casting distance of up to 150 feet, and a complete unit weight of 9,800 pounds. The unit features a 114-inch cutting width with three 14-inch diameter serrated augers operating at 450 RPM and a 38-inch diameter second-stage impeller with six replaceable T-1 steel blades. The blower is powered by a Tier IV-compliant Cummins diesel engine rated at 300 HP at 2,200 RPM with 1,050 lb-ft of torque, supported by a 20-gallon hydraulic reservoir system and a 65-gallon fuel tank with 5-gallon DEF capacity.
The specification requires all equipment to be new, latest model, current production with standard features intact. The contractor must respond with confirmation or provide alternatives for each specification section. The unit requires factory installation on the designated MDOT loader (equipment number 38-0365) with all parts, materials, and labor included by the vendor. Spare parts are included as a one-time provision consisting of complete sets of oil, fuel, air, hydraulic, and coolant filters. Paint finish must meet manufacturer's standard specifications with a minimum paint film thickness of 2.5 mils. All electrical connections require soldering and heat shrink protection or waterproof junction blocks, with no Scotch locks or wire nuts acceptable. The hydraulic system is designed for operation at temperatures as low as -40 degrees Fahrenheit and includes female quick couplers and wireless radio remote controls for operational functionality.
