For the bigger jobs like a highway or larger construction project, the SweepMaster 450-ST is the construction street sweeper your customers will crave. It takes the best attributes of the SweepMaster 300 and puts them in a bigger, badder construction sweeper. The cab features more height for increased driver comfort, increased operator visibility, a forward-slant windshield to reduce dirt and dust accumulation, a tighter turning radius, multiple auxiliary power outlets, large cup holders, and a lot more, all standard.
