Features

ADF™ (ADJUSTABLE DOWNFORCE™ SYSTEM)
The ground-breaking advancement that sets the Bourgault eXtended Range harrow series apart from the competition is the patented in-cab Adjustable DownForce™ System.

This design employs hydraulically controlled downforce or upforce to each individual harrow section, ensuring a uniform field finish even when contouring to the extremes!

THE BENEFIT OF ADF™
With the competition's harrows, changes to the tine angle or section angle will inadvertently affect the set down pressure, and visa versa.

With the Bourgault XR Series Harrows, the ADF™ feature isolates the application of down or up force from tine angle or section angle, so adjustments to one setting does not affect the other two. You can set the XR Series Harrows more quickly to achieve desired results, particularly in challenging and variable conditions.

Once the hydraulic pressure is set, downforce remains constant even through hilly land and water runs.

POSITIVE BOOM CONTROL
The XR771™ and XR751™ are equipped with a solid pull arm system. The solid pull arm provides secure control when folding and unfolding and excellent stability of the wings in fields with hills or runs.

EFFECTIVE TINE OPTIONS

  • The XR771™ is standard equipped with 7 rows of ½" x 22" tines creating an effective 1.43" spacing across the entire unit. Producers can choose optional carbide infused tines on the front 2 rows with regular tines on the rear 5, or optional carbide infused tines across all 7 rows.
  • The XR751™ features 5 rows of ⅝" x 26" tines for an effective 2.4" row spacing . Select the optional carbide ⅝" x 26" tines for extended service life.

 

EXCEPTIONAL FLOTATION
The XR771™ & XR751™ Harrows are grounded with large, hi-flotation 21.5 x 16.1 mainframe tires, as well as 13.5 x 15FI duals on its wings providing unprecedented flotation for a harrow bar.

  • The wing dual wheels are mounted in board to avoid field hazards such as posts, trees and rock piles.
  • Hydraulically controlled boom wheels greatly reduce the distance required to fold and unfold the unit.

 

CONSISTENT RESULTS IN HILLS
Maintain the Harrow Angle of Attack
The XR™ harrow sections are connected to the booms with parallel arms; this parallel arm design maintains section tilt, or angle of attack, regardless of height adjustment or field contouring.

EXPERIENCE SECTIONAL FREEDOM
Harrow sections are designed for independent vertical travel, delivering uniform results even in hilly conditions.

CONVENIENT IN-CAB CONTROL
The XR™ Series Harrows feature the 500 Control Box to provide incremental downforce adjustment, switch to upforce, or go into float mode all from the seat of the tractor.

HYDRAULIC JACK OPTION
An optional hydraulic jack provides the Operator with an easy method for lining up the harrow tongue to the tractor hitch. Once the remote is activated in the tractor, the Operator can use a valve located on the hitch to adjust the height.
