The Multiquip MQ Whiteman B46H90-QXH 46-Inch Walk-Behind Power Trowel is an industrial concrete finishing machine powered by an 8.5 HP Honda GX270 gas engine designed to smooth and burnish fresh concrete slabs. Equipped with a 4-blade spider rotor assembly, a heavy-duty gearbox, and a QXH QuickPitch handle system, this heavy-duty power trowel delivers reliable blade pitch control to accelerate concrete pan floating and final burnishing on medium-to-large commercial slab pours.
Best Used For:
- Commercial Concrete Slab Burnishing: Floating and fine-finishing large indoor industrial warehouse floors, outdoor driveways, and foundations.
- Rapid Blade Pitch Adjustments: Modifying trowel blade angles on-the-fly via the QXH QuickPitch mechanism as concrete transitions from wet paste to hard set.
- On-Site Equipment Maintenance: Accessing spider arms and thrust collar assemblies quickly through the front-mounted access panel to swap finishing blades.
Key Performance & Safety Features
- Commercial Honda GX270 Engine: Reliable 8.5 HP 270cc overhead valve gasoline engine with recoil start delivers high rotor speeds under heavy cement drag.
- QXH QuickPitch Handle Assembly: Patented spring-loaded pitch control lever allows immediate, smooth blade angle changes without manual knob spinning.
- High-Capacity Industrial Gearbox: Heavy-duty gearbox housing holds extra oil capacity to dissipate heat during continuous summer finishing passes.
- 46-Inch Guard Ring Diameter: Heavy-gauge steel tubular guard ring protects workers and jobsite forms while providing full 46-inch rotor coverage.
- Front Maintenance Access Panel: Removable front guard section grants immediate access to spider arms, thrust collars, and trowel blade hardware.
- Center-Mounted Lifting Bale: Integrated top lifting eye allows easy crane or forklift loading and transport across jobsite floors.
