The Groundsmaster® 4500-D continues to provide the clean quality of cut of a reel mower but with the maintenance ease of a rotary. At 109” width of cut, the free-floating Contour™ Plus Decks eliminate scalping, provide dramatic striping and deliver a picture perfect cut. Toro’s exclusive SmartCool™ system keeps your machine on the job and moving forward. Before things get too hot, SmartCool briefly reverses the cooling fan to blast chaff and debris from the intake screens. With a 55 hp (41 kW) Tier 4 Final and Stage V compliant turbo-diesel and the new Smart Power™ technology, that maximizes power to the cutting blades, the Groundsmaster 4500-D is an unprecedented blend of powerful productivity and refined results.
