The Vermeer SC252 stump cutter features a 27-hp engine and rubber tires. Control handles for travel, swing and raise/lower functions are equipped with sensors that recognize the presence of the operator’s hands. If the operator’s hands leave the controls for more than half a second, the clutch will automatically disengage. The cutter wheel brake will engage and the “cutting wheel engaged” indicator light will begin flashing. If contact with the handles is resumed within two seconds while the cutting wheel indicator light is still flashing, the cutter wheel brake will release and operation may resume.
