Surge Brake System & Pump Accumulator Brake System

New for 2016 - Surge Brake System
Sometimes it is difficult for the operator to detect when it is necessary to apply the brakes on the air seeder.  It can also be a considerable challenge to manually perform all of the necessary actions of turning a seeding system around on a downward slope while properly applying the braking system.  The Bourgault patent pending self-applying Surge Brake System provides a greater degree of safety and control by automatically applying the brakes as the air seeder hitch load changes from tension to compression.
The self-contained patent pending Surge Brake System is standard equipment on the 71300 & 7950 Air Seeders, and optional on the 7700 Air Seeders for the 2016 model year.
  • Compression in the hitch from slowing or traveling downhill provides braking pressure instantaneously.  A minimum amount of compression force is required to activate the brakes.
  • The Telescoping Hitch Design allows 2” of travel to supply oil and pressure to the brakes.
  • Dual calipers ensure a full tank can be controlled under normal field operation speeds.
  • Operators who have used the surge brake system provided very positive feedback regarding braking performance, even when seeding on very steep hills.
  • The biggest benefit is that the brakes will be applied when needed, without operator input.
The L7800 Air Seeder will retain the existing operator applied Pump - Accumulator Brake System, as the Surge Brake system is not designed to withstand the considerable vertical hitch load that is present on a leading air seeder.
  • Brake control is activated by a brake light, so a special tractor brake kit is not required.
  • Dual calipers ensure a full tank can be controlled under normal field operation speeds.
  • The incorporation of an accumulator in the brake system makes the brake response near-instantaneous, which is reassuring when dealing with possibly up to 85,000 pounds of towed weight.
  • The system is optimized to allow a simple switch box to brake the air seeder independently – the toggle will allow operators to momentary apply the brakes.
