Taking a closer look at a range of new Stage V-compliant products from Timberwolf.

BUILDING on its reputation as a leading designer, engineer and manufacturer of woodchippers to meet the demanding arboricultural sector, Timberwolf has launched a new range of 6-inch and 8-inch road-tow and tracked machines fitted with emissions-friendly Stage V engines.

The Timberwolf TW 230HB is a direct replacement for the TW 230DHB and TW 230PAHB models, Europe’s bestselling sub-750 kg 6-inch road-tow woodchipper range. Available with a 24.8 hp Kubota V1505 diesel engine or a 37 hp Briggs & Stratton Vanguard V Twin petrol engine, the TW 230HB offers customers the power of choice with the option to choose the fuel type that suits them without compromising on power. All the features that made the TW 230 road-tow range hugely popular with arborists remain unchanged: the exceptional performance, easy access to the engine, the wide infeed hopper, the WolfPort for quick blade changes and the large positive feedback infeed controls.

The Timberwolf TW 230HB diesel-powered variant is the first Stage V-compliant woodchipper in its class to remain under 750 kg in weight. The Kubota V1505 diesel engine now delivers 24.8 hp but with intelligent engineering and design processes, the infeed power has been improved despite the lower engine rpm.

The Timberwolf TW 230HB petrol-powered variant has been enhanced with increased ventilation to keep the engine cool and an improved exhaust design. The exhaust system has been redesigned so it sits within the chassis to offer better protection from impacts when travelling over rough ground or road furniture, and a patent pending exhaust diffuser has been introduced, reducing exhaust gas temperatures by up to 150 degrees centigrade.

The Timberwolf tracked woodchipper range has grown with the addition of a petrol variant of the popular 6-inch tracked machine, the Timberwolf TW 230VTR. The introduction of a Briggs & Stratton Vanguard V Twin 37 hp petrol engine option ensures the demands of arborists who prefer to use this fuel type are met. The petrol-powered TW 230VTR has been redesigned to ensure the machine remains perfectly balanced despite the addition of a lighter petrol engine and improved ventilation ensures the engine bay is kept cool during operation.

The TW 230VTR diesel model is powered by the same reliable Kubota diesel engine used in the TW 230HB models and the hydraulics systems have been upgraded to ensure tracking speed is not compromised by the reduced engine rpm.

The TW 230VTR range has expanded but all the features that gave it the market-leading position as the go-to tracked machine for the professional arborist are still there, including the ergonomic ride-on platform, the WolfTrack two-speed smooth running tracks, the variable track width and the easily removable hopper which helps the TW 230VTR get through the narrowest of site access points.

The Timberwolf 8-inch tracked woodchipper range has evolved into a petrol-powered pack, with the TW 280FTR fixed track and TW 280VGTR variable gradient tracked woodchippers replacing the existing 8-inch diesel tracked range.

Product marketing manager Antony Alexander said: “With Stage V engine legislation adding additional complexity, cost and risk to the high-powered diesel engines commonly used in woodchippers, we made the decision to switch over to 57 hp Kubota WG1605 petrol engines for our 8-inch tracked range.

“Timberwolf owners love that our machines are easy to maintain, simple and quick to service and very reliable, and changing to a petrol-powered 8-inch tracked range means our customers get exactly what they want at the price they want it. To include a high-powered Stage V diesel engine would result in a product that needed specialist servicing, increased downtime resulting from the diesel particulate filter (DPF) cleaning cycles and high engine temperatures which bring their own risks to the equation. With engines using a DPF there is also the risk of significant engine damage if the wrong grade or contaminated fuel or engine oil is used and we did not want to introduce these issues for our customers.”

With the strength to complete the toughest jobs in the most remote locations, both the Timberwolf TW 280FTR and TW 280VGTR feature a low vibration and ergonomically designed ride-on platform with simple to operate tracking controls for ultimate operator comfort and safety. An extra-wide feed funnel with an open top section combine to provide users with better visibility and ease of feeding, whilst the class-leading 280 mm by 210 mm in-feed aperture can process 6.5 tonnes of material per hour. There’s also Timberwolf’s legendary ‘no-stress’ auto-feed control for smooth operation, combined with a heavier rotor providing added inertia to get the job done quicker.

The Timberwolf TW 280FTR uses the WolfTrack fixed-track dual-speed tracking system, featuring a low speed gear to negotiate difficult terrain and a higher speed gear to cover distance efficiently. The TW 280FTR has a ground clearance of 245 mm to tackle uneven surfaces and its wide, smooth running tracks and low centre of gravity enhance stability on different gradients. In short, this machine has been optimised to get you there safely and fast.

The TW 280VGTR features the innovative WolfTrack variable gradient tracking system. Using heavy-duty twin arms to support each of the wide, smooth running tracks, the operator has dynamic control over track width, ground clearance and machine tilt angle providing greater control and comfort, particularly whilst navigating uneven and sloping ground up to 30 degrees.

All Timberwolf woodchippers come with a three-year no-nonsense warranty as standard, which can be extended up to an industry-leading five-year warranty for complete peace of mind.

Timberwolf Finance offers specialist finance packages, designed specifically for the needs of the arboricultural industry.

Every Timberwolf owner has access to over 250 Timberwolf-trained technicians and a network of 34 dealer depots across the UK, ready to offer expert advice as well as spares and technical support.
