Wheeled wood shredder ARPAL PRO MB-100BD

gasoline engine

Product overview

The ARPAL MB-100BD (PRO series) is a gasoline-powered drum wood shredder built for processing branches up to 100 mm in diameter into high-quality wood chips. A mid-class machine for professionals — arborists, municipal services, landscape contractors — and demanding private users, mounted on large pneumatic wheels for easy movement around the site. The machine complies with EU safety directives and is trusted by customers in Germany, Denmark, the United Kingdom, Switzerland, Canada and beyond.

The output is uniform wood chips of 5–50 mm (90% of the output; fraction depends on input material) — fuel for solid-fuel boilers and gasifiers, raw material for briquettes and charcoal, premium mulch for soil protection, and chips for professional smoking. Please note: this shredder is designed for branches — not for boards, beams, slabs or other sawmill material.

Key features

• StormBlade shredding technologies — PowerFlow cutting module: balanced welded drum with two blades and internal blade pockets that double as air blades, creating an active airflow for clean cutting and steady, clog-free chip discharge even with wet branches; every drum is balanced after welding; UCF flange bearings.
• 2 LineCut blades in ISO 60WCrV7 (1.2550) tool steel, induction-hardened to 60 HRC over a ductile core — holds its edge under constant impact without chipping.
• Adjustable, precision-ground counter-blade (10 mm steel) holds the branch firmly for clean, even cuts — even thin and flexible material like willow; adjustable via slots as blades wear.
• Additional flywheel on the drum shaft raises rotational inertia — smooth cutting at maximum diameters without engine overload.
• PowerGuard friction clutch protects the engine from overload: if a branch stalls the cutting mechanism, the clutch disengages and the engine idles instead of stalling.
• Easy Start clutch engagement near 1500 rpm — smooth, stress-free startup for both operator and engine.
• 360° rotating discharge chute with ejection height up to 1,600 mm; deflector angle adjusted by hand with two knobs — no tools needed.
• ARPAL Total Protect safety package: hopper geometry compliant with EU garden machinery safety norms; protective curtain against flying chips; safety handle on the hopper that cuts the engine instantly; belts, clutch, pulley and flywheel fully enclosed in double-sided guards (quick to remove for service).
• ErgoBase functional design: tube-reinforced hopper with thickened base that withstands constant branch impacts; 5 mm steel body on a profile-tube frame; Ø 400 mm pneumatic wheels, support leg and a balanced center of gravity; fits a compact van (Fiat Doblo / VW Caddy class) with the discharge chute removed; premium electrostatic powder coating that keeps the machine corrosion-free and "like-new" even after years of outdoor use.
• Options: additional blade sets; counter-blade.
