The Hi-Flotation™ Option

Expand Your Seeding Window

The HF™ option allows you to get into the field sooner, providing your crop with an early start. In addition, HF™ provides you with confidence when traversing challenging or restrictive terrain such as soft and narrow roads.

Stay on Top with HF™

Stay on Top

The taller profile of the Hi-Flotation™ tires helps prevent the front of the drill from “diving” in in wet conditions and reduces draft in soft field conditions.

  • The large, front mainframe tires provide 65% more surface area than the standard dual tires, while the large singles on the front wing wheels increase the surface area by 27%. This much larger footprint keeps the drill on top in conditions that would cause regular seed drills to sink.
  • As much as 70% of the weight applied from the drill to the tires is transferred through the front running gear in a high draft scenario. For this reason, the majority of the additional rubber is focused on the front of the drill.

Superior Tracking

Effectively Manage Turns with HF™

  • Transport safety is greatly improved with the Hi-Flotation™ option, particularly on narrow roads with soft shoulders.
  • The wagon-style hitch provides superior tracking when negotiating narrow back roads and approaches.

Available Hi-Flotation™ options:

  • the Full Hi-Flotation™ option provides large tires on the front of the mainframe and large, single caster wheels on the front of the wings.  Larger rear wheels are also included. (available for select units)
