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 XR871™ and XR851™ 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 XR871™ is standard equipped with 7 rows of ½" x 22" MAX LIFE carbide infused tines creating an effective 1.43" spacing across the entire unit.
  • The XR851™ features 5 rows of ⅝" x 26" carbide tines for an effective 2.4" row spacing.

 

EXCEPTIONAL FLOTATION
The XR871™ & XR851™ Harrows are grounded with large, hi-flotation 500/60R22.5 radial tires all-around, providing unprecedented flotation for a harrow bar.

  • The wing 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.
