Vermeer has also provided this machine with an expanding undercarriage. This is a real advantage for anyone facing tight spaces and difficult terrain.
With both levers forward, the machine travels at a good pace towards our work site and then, with tracks retracted by 41cm, it passes through a narrow entrance to reach the stump. Once in position, the tracks are extended to the full 1.30m to provide all the stability needed for confident operation.
At the heart of the machine is a 60hp four-cylinder Caterpillar 3024 diesel engine. It’s turbo-charged and water cooled. It’s not as powerful as the Carlton, but then it doesn’t need to be. The SC60TX consistently grinds the stump by achieving the maximum horsepower to the cutter wheel through a fully mechanical gearbox drive system.
The Tier II compliant engine, combined with the direct drive system, transfers power from a 45? upper gearbox at the engine end to a heavy-duty 90? gearbox attached directly to the cutting wheel. It’s a system that also eliminates the need for daily belt adjustment or alignment.
At the business end of the SC60TX is a 66cm diameter, 2cm thick wheel mounted with 30 carbide-tipped Vermeer Pro teeth. Having so many teeth, and with them being closely spaced on the wheel, the shock of each cutter hitting the stump is greatly reduced — in effect, it is spreading the load, and that means less strain on the engine. The result is sawdust — lots of it.
Although the cutter wheel sweep can be adjusted manually, the SC60TX is fitted with Autosweep to take care of it automatically. Autosweep constantly monitors and controls the engine speed and adjusts the cutter-wheel sweep rate to suit, maximising power to the wheel while reducing strain on the engine, drive-train and structure. It also checks the system for overheating and lack of oil pressure and the setting can be altered to compensate for different wood types. This machine has a 1.75m arc.
A fibreglass steel-reinforced bonnet protects the components from the elements and reduces noise levels. Underneath is the hydraulic tank, with biodegradable oil.
The battery is well protected and there is a useful tray for storing spare teeth and sockets. Refuelling is easy — the fuel tank is at just the right height and there is a visual gauge on the side showing the fuel level.
The tough skirt keeps the grindings under the machine and, along with a polycarbonate panel, protects the operator from debris.
If you want to go remote, you can do so with this model. A wireless remote control is available to operate the machine from a safe distance up to 30m from the stump. It will cost you an extra £2,500.
Vermeer’s warranty provides peace of mind for one year or 1,000 hours of work. There is extended, three-year or 3,000 hour coverage on gearboxes and driveline.
