When the job demands more than just mowing… step up to the 440 EFI MidMount.

Powered by a V-Twin 993cc Vanguard Big Block Engine, this machine is built to handle serious acreage without breaking a sweat. With 61" and 72" deck options, you get the flexibility to match your operation—while the G3 Hydrostatic transmission delivers smooth, reliable performance every pass.
And when it comes to productivity? This is where it separates itself.

A massive 12-gallon fuel capacity keeps you running longer, and with the ability to mow up to 7.2 acres per hour, downtime becomes a thing of the past.

Less stopping. More mowing. Real results.

Happy National Farmers Day.
