Diamond MowersDiamond Mowers SK Drum Mulcher DC Pro X

The SK Drum Mulcher DC Pro X by Diamond Mowers is ideal for large-scale brush clearing, undergrowth removal, and vegetation management. Compatible with standard-flow and high-flow hydraulic machines, this powerful attachment is offered in 60” and 72” cutting widths and can shred trees and brush up to 9” in diameter, producing a fine mulch.

The proprietary helical tooth pattern is modeled after a vacuum brush to feed material efficiently toward the center of the drum, while the patented depth control rings control bite size for optimal infeed and material processing. Anti-wrap plates prevent material from wrapping around the drum cylinder.

For maximum versatility, this attachment can utilize three different mulching teeth options based on environment and operator preference: Four-Point Hardened Steel Teeth for applications with limited ground contact; Twin Chisel Planer Teeth for intermittent ground contact; and Twin Maul Carbide Teeth for heavy ground contact and use on rocky terrain.

Diamond MowersJohn Deere Unveils Intelligent Boom Control for the 900 MH-Series Tracked Harvester.

John Deere announced its latest operator assistance control feature, Intelligent Boom Control (IBC), for the 900 MH-Series Tracked Harvester. The development of this model is a result of global collaboration between the John Deere Wheeled Cut-to-Length and Full-Tree Forestry teams, aiming to implement IBC’s field-proven technology into the MH-Series tracked harvesters.

With IBC, operators no longer need to control each independent boom function separately. One joystick moves the boom tip horizontally, while a second guides it vertically, for faster cycle times and more precise control. IBC’s smooth and fluid motion actively dampens functional change of directions, protecting boom structures and increasing wear life. IBC also automatically controls swing speed based on the overall position of the attachment.

IBC is now available on the 953MH and 959MH.

New DENIOS Lithium-Ion Battery Stations Provide Safe Storage and Transport

Lithium-ion batteries are becoming increasingly popular for their ability to deliver power from a compact size. Although they are used in a vast range of equipment, from handheld devices to cars, they are not as harmless as they appear, requiring special handling and care. 

DENIOS, a worldwide leader in the design and manufacture of storage containers for hazardous materials, introduces Lithium-Ion Stations. Designed specifically for storing lithium-ion batteries, they are ideal for storing new, questionable, damaged, defective, or End-of-life lithium-ion batteries typically found in small handheld devices. Available in two standard sizes, the containers allow the storage and transportation of batteries from 1 KG to 10KG up to 100W, which are typically used in power tools, e-bikes, medical devices, laptops, tablets, mobile devices, forklifts, cars, and more.

Every DENIOS Lithium-Ion Battery Station features solidly welded construction for a long service life, with integrated vents for passive ventilation. Lockable, hinged lid and doors keep the contents safe from unauthorized personnel. Shelving and fire extinguishers are optional.

Komatsu 845-1Komatsu 845-1 12 Ton Forwarder

The Komatsu 845 12-ton forwarder is a versatile machine that performs well in thinning, but also in lighter final felling. The 2021 model has been updated with new components, including a new chassis, a new engine and a new control system, bringing it fully in line with the larger forwarders, albeit in a slightly smaller package.

The Komatsu 845 in the 2021 line-up boasts an upgraded design with the same popular cab as the larger forwarders. The work environment is spacious and comfortable with good visibility in all directions – over both the hood and the load area, which is especially important in thinning.

Designed to maximize performance with high power and torque with a Tier IV Final fuel-efficient engine, the sophisticated control system on the 845-1 automatically adapts to changes in engine load. Computerized HST system considers machine load, terrain conditions, power and torque output to give you exceptional tractive force. Hydraulic retarder overspeed protection ensures the driveline won’t run too fast.

TigercatTigercat Industries Develops Purpose-built Forestry Dozer and Launches New Brand.

Tigercat Industries has developed a forestry dozer. The new TCi 920 will be making the rounds at several U.S. forestry industry tradeshows this spring.

The dozer will be branded under the new TCi badge, as Tigercat Industries continues to design machines for applications beyond forest harvesting systems. All products falling under the TCi brand will continue to be designed, manufactured, and supported by Tigercat Industries.

Seeking to overcome shortcomings that harvesting professionals have experienced when applying standard-build, mass production dozers to forestry operations, the TCi 920 is designed specifically for use in logging applications.

Powered by the Tigercat FTP N45 Tier 4f engine rated at 101 kw (135 hp), the TCi 920 is equipped with a 190 mm (7.5 in) pitch heavy duty undercarriage, a responsive and efficient closed loop track drive system, strong, impact-resistant belly pans, and durable structural components throughout. The TCi 920 provides the power, durability, and versatility for deck clearing, road building, and clean-up activities on logging sites.

The carefully designed forestry cab offers the operator clear sightlines augmented by the sloped front hood and rear-mounted exhaust. The cab is quiet and comfortable with a heated and cooled air ride seat, ergonomic armrest mounted joysticks, and a large touchscreen machine control system interface.
