MBW 46″ Walk Behind Power Trowel GX270 – Power Pitch Handle Less Battery & Charger

Description

Under drying midday summer winds, the MBW 46HSPLCC Walk Behind Power Trowel finishes large commercial flatwork with push-button efficiency. An 8.5HP Honda GX270 engine spins the 46in rotor across setting slabs. The bare-tool configuration requires a separate 12V battery and charger, but the electric actuator eliminates manual crank fatigue during long finishing days.

A cast iron gearcase houses precision bronze worm gearing and high-load tapered roller bearings bathed in synthetic gear fluid. Powered by an 8.5HP Honda GX270 overhead-valve engine, the drivetrain transfers torque through an industrial centrifugal clutch and cogged V-belt. Four ductile iron spider arms hold blades flat against deflection. Weighing 260 lbs unboxed, the machine maintains a wide floor stance measuring 48in wide by 76in long with the handle secured.

Key Features of MBW 46HSPLCC

Commercial concrete contractors buy MBW 46HSPLCC trowels to run existing fleet battery packs on expansive slab pours. Inquire about volume pricing to add this commercial 46in walk behind trowel to your concrete finishing equipment fleet.

• The Honda GX270 8.5HP engine produces consistent torque to spin blades through stiff mixes.
• A 46in rotor diameter provides broad slab coverage to prevent unwanted cold joints.
• Electric Power Pitch mechanism connects to standard 12V tool batteries for push-button blade adjustment.
• Four combination blades perform both initial aggregate floating and hard steel troweling passes.
• Heavy-duty cast spider arms eliminate blade flutter and maintain uniform slab contact.
• Tubular steel guard ring protects structural obstacles while maintaining clear operator sightlines.
• Centrifugal safety kill switch halts blade rotation if the operator loses control.

Bench Diagnostics Rotor Runout Metrics

Bench dial indicator tests show spindle runout under 0.0003in TIR at the spider mounting collar. The bronze gear oil bath reaches an equilibrium temperature of 141°F under continuous 65% motor loading. Blade velocity clocks between 70 and 130 RPM to produce 80 dB sound levels at the operator handle position. Spider arm deflection remains below 0.0035in under a 350 lb simulated torsional drag. The clutch engages without slippage or chatter across repeated start-stop test cycles on wet concrete.

Field Handling Maintenance Protocol

Electric pitch buttons eliminate wrist strain, while lateral swings demand 12 lbs of handlebar push across dense wet paste. Do not purchase this battery-less 46in machine if your jobsite trailer lacks compatible 12V battery packs and charging docks.

• Change engine oil with 1.16 quarts of SAE 10W-30 every 100 hours of jobsite operation.
• Grease four spider arm zerks with NLGI 2 grease after every 50 hours of work.
• Check gearbox lubricant level via the brass fill plug every 80 hours of active use.
