2017 Mack GU713

Category: Trucks (Mixer) Duty cycle shows as a vocational mixer with moderate miles for its age, the 115,460 reading suggests stop and go drum work, short hauls, and high idle time compared to highway tractors. Serial 1M2AX04C9HM031350, stock B3847P, should be verified against dash and frame VIN stamping, ECM hours and idle percentage are not provided, so hour based wear cannot be correlated here. Powertrain details are not listed, so engine family, transmission type, and axle ratio cannot be tied to route speed or drum load behavior. Service history and any drum, chute, or hydraulic pump documentation would matter more than mileage on this application, especially for PTO engagement quality and cooling system condition under sustained low speed operation. Frame rails and crossmembers are the first tell on mixers, look for flange cracking near rear suspension hangers, evidence of frame reinforcement, and any weld repairs around mixer subframe mounts. Mixer drum, charge hopper, and chute sections should be checked for thin spots, cracks, and patch plates, along with chute pin bores and latch hardware wear. Cab interior and controls should be checked for switchgear wear, HVAC function, and any warning lamp history. Brake and tire condition should be evaluated with drum work in mind, frequent starts and stops accelerate lining wear, slack adjuster travel, and steer tire shoulder wear, especially if alignment has been chasing jobsite impacts.
