2025 - Rotochopper B66L Grinder

About this machine

This Rotochopper B66L is a horizontal grinder — sometimes referred to as a tub grinder's open-feed counterpart or simply a wood hog — a heavy-duty machine built to reduce large volumes of wood waste, land-clearing debris, stumps, and organic material into chips, mulch, or biomass fuel. Rotochopper is a well-regarded American manufacturer with a strong reputation in the grinding and processing industry, producing equipment widely used in wood recycling, biomass energy production, landscape material manufacturing, and site-clearing operations.

This is a 2025-model machine in good used condition, currently located in Livingston, Louisiana, and offered at $750,000. With only 838 hours recorded, it represents exceptionally low use for a machine of this class and vintage.

Power comes from a Caterpillar C27 Tier 4 diesel engine rated at 950 horsepower, and a CAT warranty remains in effect through approximately October 2026 — a meaningful assurance of coverage on the drivetrain. Drive engagement is handled by a PT Tech hydraulic clutch, and dual radial piston hydraulic drives power the infeed system, providing robust, controllable feed force for demanding material. Shear pin protection is included to guard the rotor and drivetrain against sudden overload.

The grinding circuit is equipped with a 24-tooth mill fitted with rakers, a configuration suited for aggressive size reduction across a wide range of feedstock. A hydraulic screen change system allows operators to swap screens without manual removal of heavy components, reducing downtime between product-size changes. The magnetic head pulley on the discharge removes ferrous metal contamination from the output stream — important for mulch and biomass markets where clean product is required.

Mobility is provided by the integrated track and dolly system, including a Gen II dolly with a fifth-wheel positioned under the grinder infeed, allowing the machine to be relocated by road and repositioned on site with the track drive. A reversible radiator fan helps maintain cooling efficiency in dusty operating environments by periodically clearing debris from the radiator core, while a dedicated dust control system further manages airborne particulate at the processing zone.

Operator control and monitoring are comprehensively equipped. A wireless remote control allows the operator to manage the machine from a safe distance, and the wireless RotoLink remote monitoring system provides off-site visibility into machine status and performance. StopWatch monitoring and advanced onboard diagnostics give operators and service personnel detailed operational data. The machine is also noted as Color Ready, indicating it is prepared for colorant application if mulch coloring is part of the intended operation.

The oil pressure fault indicator extinguishes automatically once engine oil pressure reaches operating level. The machine is sold as-is, where-is.
