PHD™ Openers3330SE & 3335QDA ParaLink Hoe Drills™

Despite the distinct characteristics of each design, all three options incorporate the proven parallel link design to maintain consistent opener presentation to the soil during the seeding operation.

THE PLS™ OPENER

Consistent Results in Variable Conditions

The PLS™ Opener is highly consistent in the many different soil conditions that Producers have to face.

Note: Available only on 3335QDA ParaLink Hoe Drills™.

The PLS™ Opener incorporates a forgiving 2:1 contour ratio adapting to the many different topographical situations that you have to face.
The PLS™ is an updated version of the original PHD™ Opener where for every inch that the packer wheel moves vertically, the seed opener moves ½".
This dampening effect reduces seed depth variance due to a rough field finish or from higher seeding speeds.

Improved Approach to a Dual-Knife

The parallel linkage design maintains the fertilizer knife angle to soil flow as the arm follows field undulations.

The result is improved furrow development and more precise seed and fertilizer placement when compared to competitive dual shank openers.

Note: Available on 3330SE & 3335QDA ParaLink Hoe Drills™

The PLDS™ Opener provides a 4:3 contour ratio for the seed knife, placing the seed above and to the side of the fertilizer knife.

Just like competitive dual-knife units, the PLDS™ Opener will not guarantee adequate seed to fertilizer separation in all conditions. This close seed-to-fertilizer proximity can result in reduced emergence, especially with higher nitrogen fertilizer rates in dry seeding conditions.

The horizontal knife-to-knife distance of the PLDS™ Opener can be easily adjusted for increased separation, however, this adjustment further increases seedbed disturbance and reduces residue clearance. The solution is to combine the PLDS™ Openers with the Mid Row Bander^®Fertilizer Applicators to create the TriMax™ Triple-Shoot Delivery System eliminating the risk of seed damage from toxic fertilizer common to the dual-knife openers.

Close Contouring for Precise Placement

The PLX™ Opener provides a 1:1 contour ratio, the choice of Producers challenged with variable field topography. Essentially a rebranding of the XTC™ Opener, the PLX™ provides the same opener characteristics as it did with the 3320 ParaLink Hoe Drill™ Series.

Note: Available on the 3330SE & 3335QDA ParaLink Hoe Drills™ and the HD Frame Mounted Seeder™.

The precise 1:1 contour ratio means that for every inch that the packer wheel moves vertically, the seed opener moves the same distance of 1 inch. This, along with the closer positioning of the seed opener to the packer wheel, maintains the set seeding depth more closely over hills and through runs.

It's All About Choice

The Bourgault PHD™ seed drills allow you to choose the opener and packer wheel combination that works best for your conditions and farming techniques.

Opener Selection

The ParaLink™ Seed Opener maintains a consistent presentation of the seed opener tip to soil flow, regardless of its position. This feature allows you to select the seed opener tip that works best for your conditions and farming techniques.

Packer Options

The 4.5" V-Style Semi-Pneumatic Packer provides a more aggressive, narrow profile with excellent mud-shedding characteristics and is commonly used with narrow openers (¾" to 2").
The 5" VU-Style Semi-Pneumatic Packer provides a more rounded v-style profile with good mud-shedding characteristics and less prone to over-packing (¾" to 2").
The 4.5" U-Style Semi-Pneumatic Packer provides a wide, rounded packing profile and is typically matched with a ¾" to 2" wide opener.
The 5.4" U-Style Semi-Pneumatic Packer provides a wide, rounded packing profile and is typically matched with a 2" to 3" wide opener.

Note: Over the years, Bourgault has transitioned to offering only semi-pneumatic packers as they are immune to punctures/flat tires.

Interchangeability

PLS™ and PLDS™ Openers share the same platform

PLS™ & PLDS™

The PLS™ and PLDS™ Openers share the same platform, supporting conversion capability. This increased flexibility is appealing as farming practices change, or when trading in on a new or buying a used ParaLink Drill™.
