Features

Self-Feeding Operation

The PRO 475 uses a self-feeding system that combines a large vertical hopper, a heavy-duty chipper knife, and an airflow channel to help draw branches into the cutting chamber.

The system automatically pulls suitable branches into the cutting area while directing processed wood chips through the discharge chute, reducing the amount of manual feeding required during operation.

Large-Capacity Hopper

The 17″ × 27″ hopper opening accommodates branches up to 4.75 inches in diameter and provides a large opening for loading suitable branches and brush.

The larger hopper can reduce the need to trim branches before feeding them into the chipper.

Electric Start

The PRO 475 is available with an electric-start configuration for convenient engine starting.

A manual-start configuration is also available.

Standard Pin Hitch

The standard pin hitch allows the PRO 475 to be towed with a compatible lawn tractor or ATV.

Verify towing compatibility and applicable operating requirements before use.

Optional Road-Tow Package

An optional road-tow package is available for transportation on public roads where permitted.

Road-tow equipment, requirements, and legal restrictions may vary depending on the applicable location and configuration.

Heavy-Duty Flywheel

The PRO 475 uses a 17.75-inch flywheel weighing approximately 50 pounds.

The flywheel stores rotational energy during operation and helps provide consistent cutting action as branches enter the cutting system.

PRO-SPEC™ Hardened Steel Chipper Knife

The PRO-SPEC™ chipper knife is manufactured from high-carbon, high-chromium forged alloy tool steel and is designed for durability and edge retention.

Regular inspection and sharpening, as required by the manufacturer’s maintenance instructions, can help maintain chipping performance. Keeping a replacement knife available may help reduce downtime during maintenance.
