2026 Grasshopper MidMount™ 400 Series 440 EFI 61"
Our full-featured, top-of-the-line MidMount™ mower series can be fitted with a 72-inch deck and powered by the legendary power of the Kubota® Clean Diesel engine or the Vanguard® BIG BLOCK™ gas engine.
Features may include:
- Unique four-spindle design evenly distributes loads of clippings out the back of the mower and away from the operator and engine.
- Trim ultra close to buildings, easements, and landscaping without worrying about scraping and damaging your deck—or the property you're mowing.
- Made from diamond-plated aluminum, this canopy mounts to the ROPS for added sun protection and all-day comfort.
- Airless tires that perform like pneumatic tires but without the inconvenience of flats. These tweels are available as turf drive tires, tail wheels, and deck wheels.
