CBI Magnum 4800 Grinder
Unlike tub grinders, the horizontal feed system on the CBI 4800 features the safety advantage of an enclosed grinding chamber eliminating the hazards of flying debris on the job site. With a horizontal forced feed system, material fed into the machine does not bridge or birds nest before coming in contact with the rotor. At 88,000 pounds and equipped with an 880 horsepower Caterpillar engine, the CBI 4800 is more than capable in meeting the demands of tough wood waste and stump grinding tasks. |

Excavator Mounted
Flail-Type Mower
Most of our competitors use 12 metric ton excavators. Northern utilizes a 16 metric ton excavator for its mower applications.
The advantages are increased working horse power, more draw bar pull for climbing hills, sufficient lifting capacity for moving mats, 28" pads as opposed to 24" pads
Northern also adds a 6 cylinder, 155-horse power (as compared to a 4 cylinder, 125 horse power) auxiliary engine enabling the mower to mow heavier brush without waiting for engine recovery.

Flail-Type Mower
The Flail-Type mower reduces small trees and brush into a small shredded chip that is broadcast evenly over the grounds surface.
Unlike the Hydro Axe rotary type mower, the Flail-Type head when mounted on an excavator is able to mow up to and around obstructions such as rocks or posts, reducing or eliminating the need for follow up operations by ground personnel. Chip discharge is directed generally downward, making this machine safer than rotary type mowers. |

Excavator Mounted
Flail-Type Mower
An excavator mower working from swamp mats in a wetland. With cables attached to the mats, the operator is able to move the mats with the mower head by swinging them from behind the machine to the front. This enables the mower to proceed into new material as it mows.
In this photo the mower is working on top of a peat like sediment that is over 24 feet in depth. This organic sediment has accumulated in this lagoon since 1927. The lagoon was drained in the summer of 1999. Small trees and brush grew in from the edges and needed to be removed prior to the excavation of the sediment. |

Excavator Mounted
Flail-Type Mower The excavator mounted flail-type mower evenly disperses a uniform shredded chip that decomposes rapidly. The chips have the added benefit of providing a temporary mulch on the grounds surface that prevents soil erosion and aids in dust control during dry conditions. |
