Valmet has Comfort, Production
Updates to the new Valmet 911.4 improve machine performance, harvesting speeds and operator comfort. It includes the new Valmet “comfort” bogie design for better maneuverability and stability. The bogie, combined with the refined hydrostatic transmission, delivers 22% more tractive efort to improve travel speeds, maneuverability and uphill harvesting. In-cab changes include 32% more cab volume. Including standing headroom, the added space is also reconfigured to provide more comfort, storage and room for a trainer. The operator seat now swivels 180-degrees for better all-around view, and the advanced ECC climate control for improving air quality is now standard. MaxiXplorerT computer control is more powerful and markedly faster, which makes harvesting faster. Work modes are more advanced, easier to use and more intuitive. Hydraulic head pressure (360.2 only) has increased to 280 bar for more effective cutting and improved fuel economy.
Valmet 941.1 Updates: The size, strength, comfort and productivity of the Valmet 941.1, has been enhanced with “dot-1” upgrades including “in-cab” storage and ergonomic updates. Plus, more powerful computer system updates with better communication between units. MaxiXplorerT is a windows-based computer control system that is far more advanced and powerful. The system is easier to use, manages information better and improves the operator’s ability to work faster and more effectively. www.komatsuforest.com
CFI saw the new 1270E harvester working in Finland last spring, our sneak peak at a series that will eventually include the 1070E thinning machine and 1470E final felling and large timber harvester. Changes over the successful D include an improved cab levelling and rotating system, with rotation now at 160 degrees and levelling to 17 degrees side-to-side and 10 degrees fore and aft. The harvesters also use the same Deere-made cab as the new E series forwarder. In fact, components, controls, and software are as identical as possible, allowing operators to jump back and forth between harvester and forwarder as painlessly as possible. As in the forwarder, controls have been placed for ergonomics, and low windowsills and arc-shaped windows maximize visibility.
The measuring, control and automation systems have also been improved. The TimberMatic system software has been made more user-friendly, and a single program allows operators to adjust all settings instead of the three required in the D-Series. Troubleshooting and all required maintenance documentation is now available from the on-board computer. The 1270E sports an all-new CH7 boom with higher lifting and slewing torque, yet according to Deere is more agile for select cutting. It also boasts very impressive reach numbers, out as far as 11.7 m (38.4 ft).
Backed by Caterpillar’s worldwide dealer network for parts and service support, the Cat 550 is equipped with a 147 kW (197 hp) Cat C7 engine with ACERT Technology, which integrates and controls fuel and air delivery for strong performance and compliance with Tier III emissions regulations. The 6WD harvester comes standard with a 8.23m squirt boom designed for a dangle head. Lift capacity at full reach is 2,268 kg. The boom’s V-shaped bottom extends the life of the wear pads and minimizes side-to-side movement as the boom telescopes in and out. The harvester can also be equipped with a fixed head boom with a lift capacity of 3,800 kg at full reach.
The 550 travels up to 19 kph, is easy to maneuver and provides a smooth ride with little vibration. The operator has an unobstructed view of the work area as a result of the cab forward design, large side windows and the boom and cab rotating together. The auto leveling mechanism tilts in all directions to give the operator better visibility and more comfort on steep or uneven terrain.
Rottne introduced their largest harvester, the H-20, to Canadian soil at DEMO International 2008 near Halifax last September, and through live demos at customer sites in Nova Scotia. It is a stable, powerful harvester with a head designed for big timber. In demos here and on logging jobs overseas the H-20 has proven itself to be a reliable and highly productive larger harvester with low operating costs. The modern cab offers superb comfort with air suspension seat, wide armrests with lever panels that are individually adjustable as well as air conditioning with automatic climate control. The operator has fantastic visibility as the cab swings with the loader and is self-leveling. The Rottne 700 harvesting head is controlled by the Rottne D4 measuring and control system, a can-bus based system that requires only seven wires to the head. All pressure settings to the harvesting head are easily checked and set from a large screen inside the cab. The large bogie in the front with 750/45 x 30.5 tires makes for a light footprint in soft ground, and can easily be equipped with tracks for deep snow or very soft ground. The whole power train with engine, pumps, and transmission as well as tanks for oils and diesel are located at the rear and are very service friendly due to tanks tilting sideways and large swing open door and side mounted radiator. The H-20 joins its little brother, the mid-sized H-14 thinning and clearcutting harvester, which shares a common cab and easy-access design.
The Prentice 2510 6WD harvester features a 147 kW (197 hp) Cat C7 engine with ACERT Technology. The patented ACERT Technology integrates and controls fuel and air delivery for strong engine performance and reduced emissions compliant with Tier III regulations. The harvester has a lift capacity of 2,268 kg at full extension. It travels up to 19 kph, is easy to maneuver and provides a smooth ride with little vibration. The V-shaped bottom on the standard 8.23m squirt boom adds to the life of the wear pads inside the boom and minimizes side-to-side movement as it telescopes in and out. The harvester can be equipped with either a dangle or fixed head.
The cab forward design, large side windows, and the boom and cab rotating together on the upper turntable provide the operator with an unobstructed view of the work area. The auto-leveling mechanism tilts in all directions giving the operator better visibility and more comfort on steep or uneven terrain.
The front entry cab allows for easy and safe entry and exit. An IQAN MDL computer with a full function graphics display monitor, Sure Grip joystick controls and a 360-degree lighting package are standard. www.prenticeforestry.com
