MBW 46 Inch Walk Behind Power Trowel GX390 – Power Pitch Handle w/ Battery & Charger

Description

Spinning four 46in blades under electric push-button pitch control, the MBW 46HLPBCC Walk Behind Power Trowel maximizes finishing efficiency on large commercial floors. A Honda GX390 11.7HP engine provides immense torque to finish stubborn concrete. The onboard battery system adds an electrical maintenance component, but instant pitch adjustment eliminates manual crank fatigue.

A heavy-duty cast iron gearbox encloses a precision bronze worm gear bathed in synthetic lubricant to handle high torque. The Honda GX390 11.7HP engine sends commercial power through a heavy centrifugal clutch and cogged belt drive. Thick cast iron spider arms maintain true blade alignment under drag. Weighing 275 lbs unboxed, this powered unit features a broad floor stance measuring 48in wide by 76in long with the power handle attached.

Key Features of MBW 46HLPBCC

Commercial contractors buy MBW 46HLPBCC trowels to speed slab closing on industrial projects. Check current pricing to purchase this commercial 46in walk behind trowel with push-button power pitch.

• The Honda GX390 11.7HP engine supplies massive power to spin blades through low-slump concrete.
• A 46in rotor sweep covers broad square footage to seal slabs before crusting starts.
• Electric Power Pitch handle uses a 12V actuator to change blade tilt via buttons.
• Included 12V battery and charger keep the electric pitch actuator ready for work shifts.
• Four combination blades float aggregate and burnish flatwork to a dense sheen.
• Heavy cast iron spider arms stop deflection and prevent chatter marks on slabs.
• Tubular steel guard ring protects obstacles while maintaining clear sightlines.
• Centrifugal safety switch shuts down engine power if the operator releases the grip.

Bench Diagnostics Rotor Runout Metrics

Spindle dial indicator tests confirm radial runout under 0.0003in TIR at the spider hub collar. The bronze gear drive reaches 144°F under sustained 75% mechanical engine loading. Rotor speed clocks between 65 and 135 RPM, producing 83 dB sound levels at the operator handle position. Electric actuator stroke draws 8A at 12V under maximum blade tension, adjusting pitch in 3 seconds. Cast spider arms show zero measurable deflection under 420 lbs of applied mechanical drag force.

Field Handling Maintenance Protocol

Electric pitch buttons eliminate wrist strain, while lateral swings require 13 lbs of handlebar push across wet paste. Do not purchase this battery-equipped 46in machine for small residential basement pads, tight footings, or jobsites lacking dry battery charging stations.

• Change engine oil with 1.16 quarts of SAE 10W-30 every 100 hours of operation.
• Grease four spider arm zerks with NLGI 2 lithium grease after every 40 hours of active slab finishing.
• Inspect gearbox lubricant through the brass sight port every 60 hours of field runtime.
