The WBH-21EF Whiteman Front-Wheel Drive Power Buggy stands as the industry’s leading solution for large-scale, efficient material transport on concrete and construction jobsites. With its impressive 21-cubic-foot payload, tough poly tub, high-torque Vanguard engine, and advanced hydrostatic drive system, this Multiquip Whiteman buggy is engineered to maximize productivity, reliability, and operator comfort—all while keeping maintenance and jobsite delays to a minimum.

Overview: WBH-21EF Whiteman Front-Wheel Drive Power Buggy

The WBH-21EF is purpose-built for moving concrete, gravel, aggregates, demolition debris, or landscape materials with unmatched speed and capacity. Whether pouring commercial slabs, backfilling trenches, or hauling debris away from dense construction zones, this power buggy’s big poly tub and smooth hydrostatic controls get the job done, shift after shift.

Key Features and Performance Advantages

• 21 Cubic Foot Poly Tub: High-density polyethylene (HDPE) body resists impacts, chemical attacks, rust, and concrete buildup, holding up to 21 cu. ft. (595 liters) or 3,200 lbs. (1,451 kg) per load. Its smooth interior boosts cleanout speed and reduces labor after each pour.

• 18 HP Vanguard Twin-Cylinder Engine: Rugged, powerful, and reliable, this gasoline engine (with electric + recoil start) provides ample torque for fully loaded tubs and demanding terrains, day after day.

• Hydrostatic Front-Wheel Drive: Infinitely variable speed—no shifting, no clutching—delivers a max speed of 7.25 mph and precision reversing, allowing operators to easily control heavy loads up inclines, across rough ground, and in tight site layouts.

• Superflex Foam-Filled Tires: Airless tires minimize downtime from flats and improve stability and ride quality over rebar and debris-strewn sites, ensuring all-day jobsite readiness.

• ANSI-Compliant Braking: Meets top safety standards for reliable starts, stops, and stable load management.

Technical Specifications

Productivity Powerhouse

The WBH-21EF transforms material handling efficiency for pour crews and finishers. Its ultra-large tub means fewer trips, reduced cycle times, and less overall labor needed for concrete placement or debris removal. The HDPE tub’s smooth surface resists sticking, enabling fast discharge of even wet or sticky material and eliminating stubborn post-job cleanouts.

All controls are designed for operator ergonomics, from the easy-to-reach throttle and hydrostatic lever to the heavy-duty braking and lift-assist forklift pockets. Superflex tires cushion the ride, absorbing site shocks for safe, confident material movement.

Durability, Maintenance, and Uptime

• Rugged HDPE Tub: Outlasts metal competitors, never rusts, and shrugs off chemical spills and harsh weather.

• Vanguard Engine Reliability: Known for extended service intervals and easy upkeep with robust part support network.

• Foam-Filled Tires: Greatly reduce the risk of job-halting flats and provide a consistent ride over rebar, concrete, and rough fill.

Easy-access service points and simple regular maintenance make the WBH-21EF a top performer for day-in, day-out site work—maximizing ROI and reducing downtime.

Safety & Operator Ergonomics

• Intuitive Controls: Hydrostatic drive and ergonomic handlebars reduce fatigue and boost new-operator confidence.

• Stable Chassis: Low center of gravity means less risk of tipping, even at max payload.

• Excellent Visibility: Operator placement, clear lines of sight, and simple platform improve both efficient material drop and jobsite safety.

Best-Fit Applications

• High-volume commercial slab and flatwork concrete pours

• Moving demolition debris or waste on large renovations

• Aggregates and bulk material transport for landscaping or fill

• Rapid production backfill in sitework, trenching, or utility projects

• Interior and confined site work—navigates 44"-wide openings

Accessory Options and Upgrades

• Heavy-duty replacement tires or tub liners

• Dual/tandem tire kits for load or width optimization

• Bucket inserts for sticky, abrasive, or special loads

• Maintenance kits (filters, fluids, consumables)

• Fleet signage and custom decals

• Lighting kits for pre-dawn or night pours
