Timberwolf TW190

The 190 is setting new standards in design and operation for the 7.5" class of chipper.

It’s British-built and it’s quality. From the ground up, this is a substantial machine, particularly the chassis. It’s a 100mm x 50mm C-section chassis, made from five-millimetre-thick steel and built to take abuse. It also has two strength bars running up the middle like a reinforced A-frame, which, when combined with excellent ground clearance, make the machine suitable for towing around town and over speed bumps. But there’s more — this chipper is full of high-spec components and good ideas.
The flip-top rotor housing reveals a heavy-duty rotor comprising two heavy-duty blades mounted at zero degrees to the rotor. This means there is no need to reset the anvil gap when changing blades — just swap them.
The feed rollers are some of the most aggressive we’ve seen. They have 150kg of crushing power and just over 1,000kg of pulling power — the rollers are bladed so they can cut into the material. They bite and with their awesome grip they even tackle poorly snedded material. One tester finds it saves time on preparing the material prior to chipping.
The technology of this chipper is suitably matched to a power unit at the forefront of engine technology — a 35hp Kubota V1505 water-cooled diesel engine. It provides plenty of grunt and ensures that the team is constantly busy feeding timbers into the machine.
The feed hopper is big. At the front, where the pull is strongest, there is over seven millimetres of metal. The hopper is also fully supported by the chassis — it’s not just hanging on a fixing.
Our tester is impressed by the safety mechanisms. “They are a lot better than some I have seen. It’s a good machine to use,” he says.
This chipper has electro-hydraulic feed. It means the operation of the chipper is push-button. There are three control buttons above the hopper. The green gives forward pull and operates as soon as it is touched. Blue is the reverse feed and works only as long as it is depressed, allowing the wood to be freed before engaging forward again. The red button above the hopper and a second one at the front stops the machine. So does the safety bar. And that is all the safety bar does.
A tester likes the position of the safety bar along the bottom of the funnel and he says it makes him feel safe. The bar has been designed and engineered to eliminate false tripping — our team had no problems with it unnecessarily killing the machine. One of our men gives the push-button controls 10 out of 10. “It’s so simple,” he says. The 190 is fitted with a quick-reaction no-stress device.
It’s clear that Timberwolf has spent considerable time studying current and future CE-compliance and safety. There are the obvious things like funnel reach distance, rotor housing thickness and visible sound power level signs. The company goes further and indicates the sound pressure level for the 10m-exclusion zone distance. And to ensure that ejected materials do not pose a risk, the discharge chute rotates only 270°. It will not discharge over the operator.
We also like the opaque fuel tank. It holds a sufficient amount for day-long operation and it means you are able to check the fuel level at a glance.
