At SkogsNolia 2019, Komatsu Forest launched an upgraded product range, with the majority of the machines new 2020 models. The machines are equipped with a brand-new engine installation conforming to the latest emission legislation. The new, future-proof control system, MaxiXT, was also launched.
Alongside these, the company presented a number of quality improvements and new functions to simplify day-to-day tasks for machine operators and to increase profitability. These include the new MaxiVision service, which takes production planning to a whole new level.
All 2020 harvester models have been upgraded, from the agile Komatsu 901 thinning harvester through the bestselling eight-wheel Komatsu 931XC to the stately Komatsu 951. Among the forwarders, the three largest – the Komatsu 855, 875 and 895 models – have been upgraded.
One standout feature is the brand-new engine installation, which conforms to the latest emission legislation (Stage V). It also offers many other benefits, such as an all-new AdBlue system, a new exhaust system and hydraulic tappets. Despite the new, larger engine installation, the machine boasts the same slim design with good all-round visibility and views – right down to the wheels.
Another new announcement is the MaxiXT control system, the machine’s nervous system, controlling everything from the engine to the crane and the head. In connection with this, the Automatic Central Lubrication option is now integrated with MaxiXT, making it easy to monitor from the cab. What’s more, on harvesters the grease tank has been doubled in size, meaning less refilling for the operator. MaxiXT brings with it improved anti-theft measures as the operator must log in to the system to start the machine, or else use a remote key with a unique operator ID.
Yet another added feature is the ability to record signal sequences to send to support, for simpler and speedier troubleshooting.
As for the forwarders, they have been upgraded in a number of areas. Smaller but important details, such as better wear plates on the front blade, longer wiper blades on the side windows and less reflection from the gate. A much-requested new forwarder feature is the SpeedShift option – a smart solution that enables the operator to use the machine’s full speed range without having to stop to change gear. This makes travelling to the landing faster and, as the collapsible steering wheel has been replaced with a handy mini steering wheel, driving there is also more straightforward.
Another new addition is the Overspeed Protection option, protecting key transmission components from over-revving.
On the harvesters, offroad manoeuvrability has been improved in several areas. Parts of the rear axle have been redesigned, providing higher ground clearance and making it easier to tackle steep ditches and other obstacles in challenging terrain. On top of this, both the tractive force and the power steering have been refined, improving offroad manoeuvrability and increasing productivity. Harvester operators will also notice a large number of additional storage spaces, as well as practical finesses such as a portable lamp to better facilitate servicing.
Moving on to the heads, there is the new Komatsu C164, which is a perfect match for the Komatsu 951. This head is based on the same technology as the C124 and C144 models, with the stem held up by the feed rollers and the delimbing knives used primarily for delimbing. The head has four powered feed rollers and the Constant Cut function, ensuring an even cutting speed throughout the cutting cycle.
In addition to the new machine features, a brand-new service – MaxiVision – was launched as part of MaxiFleet. MaxiVision helps the operator to visualise the current state and conditions of the forest. Different map views provide the operator with data about ground conditions and the rest of the team’s production, enabling them to plan their work as efficiently as possible and with minimal forest impact. Since the service is cloud-based, updates occur in real time and any changes are immediately seen on-screen in the cab.
The 2020 models were launched in conjunction with SkogsNolia in mid-June.
