Features

Features

  • COVER THE TOUGHER TERRITORY: The 425 is outfitted with a larger, more aggressive tire package. This makes for a tractor with increased ground clearance and greater operational stability over challenging terrain. It means you can get on board and operate in the toughest of territory with complete comfort and confidence. With this increased operating confidence, you’ll be able to get even more out of what your land has to offer.
  • FRONT LOADER SIMPLY PUT, LIFT MORE: The pure power of the 425 means it has a loader capacity of 1,200 lbs. at the pivot pin. That’s power usually associated with much larger tractors. But that’s Yanmar’s strength- fuel-efficient diesel engines that help you do more.
  • PRECISE REAR IMPLEMENT CONTROL: Making sure your rear implements operate in a position that’s always repeatable means your tasks get done quickly and more accurately. And that’s what Yanmar’s unique True Position Control delivers. An easy-to-reach control lever adjusts the rear implement's operating height and makes sure it’s always right where you need it.
  • Cast iron transmission, front axle, and dual hydraulic pump
  • Two side-by-side hydrostatic transmission pedals
  • Full-frame chassis
  • Electro hydro independent PTO with one-touch on/off
  • Front-end loader capacity + quick hitch
  • Smooth, hydraulic power steering
  • Dual rear remote valve & 12V outlet standard
