The durability and precise seed placement of the 3720 has been proven in the field for several years. A new evolution of this model now offers Producers another option to best meet their agronomic and logistic needs. The latest generation has evolved into two distinct series:

  • the 3720 Standard Edition which is offered on a solid frame platform; and,
  • the 3725 Quick Depth Adjust that incorporates the quick depth adjust frame.

The Bourgault 3720SE PCD solid frame design offers less moving parts with opener depth set individually on each opener

3720SE ParaLink Coulter Drill™

The Standard Edition is a basic system that provides excellent land following capabilities, straightforward operation and rugged durability.

  • The proven solid frame design provides a traditional approach of adjusting seed depth strictly at the opener level.
  • The solid frame design offers less moving parts, with opener depth set individually on each opener.

Producers have the unique ability to quickly and easily adjust seeding depth at the frame with the Bourgault 3725QDA PCD

3725QDA ParaLink Coulter Drill™

  • The Quick Depth Adjust drill frame offers the unique ability to adjust seeding depth at the frame quickly and easily.
  • Adjustment shims at each rear running gear provides a total of 3/4;" of total adjustment range.
  • Producers can adjust seeding depth from field-to-field and achieve the best seeding job possible without sacrificing productivity.
QDA Shims

The 3725QDA uses a hydraulic cylinder and shim assembly on each rear carrier wheel to set the seed depth. Adding or removing shims changes the angle of the frame, which results in seed depth change because of the unique geometry of the PLW opener. The total range of seed depth change with the Quick Depth Adjust is 3/4".

The Hi-Flotation™ Option

3720 ICD available with the Hi-Flotation option in select sizes

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.


Hi-Flotation Drill in Transport

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)
  • the Center Hi-Flotation™ option offers large front tires with wagon-style steering on the mainframe paired with the regular dual front casters on the wings.  Larger rear wheels are also included. (available for select PCD™ units);
