Our Carlton 35HP also known as our 'Big Yellow' is our four-wheeled self-propelled unit that features a 35hp motor with a cutting depth reaching below ground of 12", cutting height above ground is 34", 21-inch diameter cutting wheel, letting you grind faster and smoother through those larger stumps without breaking a sweat. Big Yellow is also narrow enough to fit through your standard side gate allowing us to complete those bigger stumps in tight access areas. If this machine doesn't fit our other machines sure will.
