It’s the best of both worlds: a larger than life rotary mower that devours acres of rough one moment, and the next is an ultra-precise cutting machine. The Toro Groundsmaster 4500-D does it all with more torque and power than any mower in its class. With full-time, bi-directional 4-wheel drive and individual wheel brakes, the Groundsmaster 4500-D delivers the kind of superior handling and control that keeps your operators moving at peak performance. Engineered to never lose its cool. Here’s the coolest advancement in our relentless drive to end downtime. When things start to heat up under the hood, our exclusive SmartCool™ system briefly reverses the cooling fan and blasts chaff and debris from the air intake screens. The result is nonstop productivity.
