MRB III
Overview
MRB® III
OPTIMAL NITROGEN PLACEMENT IN ONE-PASS SEEDING
 
Golden Rule of One-Pass Seeding - the goal is to apply all of the seed and fertilizer requirements in a single operation without the seeding operation itself incurring risk to the potential crop.
Mid Row Banders minimize the risk of fertilizer damage to your seed by placing the crop’s nitrogen fertilizer requirements between every other seed row eliminating the risk of fertilizer toxicity and salt effect, and eliminate seedbed quality issues such as soil lumping and excessive soil disturbance resulting in premature seedbed dry-down.
 
The MRB® III Fertilizer Application System is the most advanced and durable mid row banding system offered by Bourgault. The extensive use of well engineered cast components, convenient depth adjustment, and hydraulic engagement control will mean more time for you in the field seeding, and less time spent adjusting or maintaining.

Floating Carbide Scraper – The floating inside scraper maintains a good furrow in a wide range of seeding conditions.
Hydraulic Actuation – The hydraulically controlled MRBs are synchronized with the seed arms or shanks for efficient in-field operation.
Double-Tapered Roller Bearing Hub – You can expect a long service life with the high capacity hub and spindle assembly. 
Parallel Link Arrangement – The MRB body is mounted on parallel arms for a constant disc attack angle and seed boot / liquid tube orientation regardless of its operating depth.
Simple Depth Adjustment – Shims on the hydraulic cylinder are used for setting the depth.
Maintenance-Free Coulter Arm Pivots – The MRB arm pivots will stand up for the life of the seeding system, even in hard or stony soils.
Fine Scraper Position Adjust (Behind Cast Mount) – The position of the scraper relative to the edge of the disc can be adjusted in fine increments.
Coarse Scraper Position Adjust – Adjust the whole scraper/boot assembly to maintain the optimal scraper-to-disc position as the disc wears.
Combo-Boot – The versatile combo-boot allows you to select between dry, liquid, or anhydrous forms of nitrogen application.
Long Wearing Coulter – The large single bevel boron steel coulter is set to open the soil just enough to deposit the fertilizer.
