How the ST6P HD is built

  • FörstGrip feed rollers

    Twin hydraulic rollers. The top one lifts on an arc and is held down by two heavy springs, so it climbs over butt ends and drags in forks and awkward limbs.

  • Open-top flywheel

    A 640 × 25 mm flywheel with twin 8-inch blades throws the chip instead of blowing it, so wet, green material is far less likely to block the chute.

  • 40hp V-twin petrol

    A Briggs & Stratton Vanguard with electronic fuel injection: fuel on demand, and a three-year engine warranty.

  • All-steel build

    Steel panels throughout, built for utility arb work. That is the difference between the HD and the standard ST6P.

  • AutoIntelligence control

    Sealed electronics that run the no-stress feed, tell you when a service is due and prompt the routine checks. Proof against water and vibration.

  • Touch-button feed

    Illuminated IP69-rated touch pads on both sides of the hopper, with a traditional feed bar as well.

  • Variable roller speed

    Slow the feed for hardwood, speed it up for brash.

  • Easy-access anvil

    The anvil turns or swaps in minutes, so a fresh edge is never a workshop job.

  • Clear fuel tank

    A see-through 30-litre tank with a wide filler neck. You can read the level from across the yard.
