2017 ROTOCHOPPER B66

This 2017 Rotochopper B-66 has received major component work within its last 1,200 hours, including a Rotochopper power-feed overhaul and recent mill bearings. That maintenance history addresses several high-wear areas buyers examine on a grinder with 7,950 hours.

Who This Machine Is For

• Land-clearing contractors — the tracked undercarriage supports movement around active clearing sites.
• Mulch producers — interchangeable screens and grinding components control finished material size.
• Wood-recycling yards — the large infeed handles logs, pallets, and bulky wood waste.
• Biomass operations — the 950 HP engine supports high-volume fiber processing.
• Buyers comparing horizontal grinders — the B-66 offers a large grinding chamber and high-horsepower powertrain.

What It Grinds

• Logs and whole trees — the large infeed accepts bulky land-clearing material.
• Brush and green waste — processes limbs, vegetation, and storm debris.
• Pallets and wood waste — reduces clean wood into mulch or biomass feedstock.
• Slabwood and wood chips — handles sawmill material and regrind applications.
• Sorted construction debris — processes suitable wood-based material after contaminants are removed.

This machine is not intended for hard rock or unsorted demolition waste. Production and finished size depend on material condition, screens, and grinder tips.

Specs in Plain Language

Its 950 HP CAT C27 provides power for large wood and demanding grinding applications. The emissions tier was not supplied and should be confirmed from the engine plate. The B-66 has approximately 66-inch-wide by 36-inch-high infeed clearance, allowing it to accept large material with less preparation. About 1,200 hours ago, Rotochopper overhauled the power feed, roller tray, bearings, and related components. The drive belt has approximately 1,500 hours, while the mill bearings have about 200 hours. The belly belt, associated bearings, and charge pump have about 100 hours, and the mill was balanced. The seller also reports using Texas Refinery Corp engine oil during the last 5,000 hours. Our wood grinder buying guide explains how feedstock and machine setup affect the finished product.
