Power comes from a four-cylinder turbo-charged 66hp Kubota diesel engine. This power plant has 27 per cent more torque and 10 per cent more horsepower than the previous 7015 model, while also being quieter. The engine is completely enclosed.
The four-speed control allows the operator to choose between high-speed travel models and high-torque cutting modes at the flip of a switch. When grinding, the patented turntable design comes into play to allow a giant 70in (177.8cm) sweep.
The machine's wireless remote control ensures that the operator can stand a safe distance away from the noise and dirt of the grinding head. But we find the dirt does not fly - guarding ensures that.
"There is nowhere for the dirt to go," notes Jane, moving debris from the hole so he can see the remaining stump. Of course, he wants it to go deeper. On the positive side, he appreciates the extra power. "There is plenty of power in this one, and it is cutting the stump quickly," he adds.
The SP7015 is fitted with Carlton's Razor wheel and 32 teeth. Goulbourne is impressed by the build. "This is certainly a well-engineered machine," he concludes.
