Municipal public works departments, DOT programs, and private sweeping contractors running arterial and collector routes where a full-size sweeper earns its keep. The M4 is the flagship mechanical Global, handling heavy debris like road millings and chip seal at 3 tons per minute while the 18.5-foot turning radius keeps it maneuverable on city streets.
Municipal arterial and collector street sweeping
DOT and state highway shoulder programs
Post-construction cleanup including road millings and chip seal
Industrial park and parking lot sweeping for private contractors
Fall leaf collection with standard leaf gate system
Single-engine Cummins 280 HP design replaces the dual-engine setup competitors use, that's half the oil changes, half the filters, and one less engine to fail on a shift. The 5.6 yd³ hopper beats the 4.5 yd³ that auxiliary-engine competitors offer because Global isn't giving up cargo space to a second engine. Hydraulic hoses and manifolds live in a centralized weatherproof locker, not buried in the frame, so your mechanic diagnoses problems at eye level instead of on his back.
Fleets running aging dual-engine sweepers with two sets of maintenance intervals to track, or operations where a competitor's 4.5 yd³ hopper forces dump cycles every 45 minutes instead of every hour.
For residential cul-de-sac routes, the three-wheel M3 has a 12.5-foot turning radius and a lower GVW. For highway-speed sweeping or side-dumping into a dump truck, step up to the M4 HSD with 65 mph travel and 18,000 lb lift capacity.
