MT-NH3 II

Improved anhydrous rate control!

The MT-NH3 II is an automatic rate controller designed specifically to control anhydrous ammonia. It provides a complete picture of critical application functions and an accurate record of work performed.


  • Built-in capability for future VRA
  • Records area and volume in 3 independent pairs of counters so individual jobs can be tracked
  • Enhanced reliability, precision and accuracy
  • Troubleshooting enhancements including "no speed" and "no flow" messages
Measuring Capabilities
  • TOTAL: displays total lbs. (kg) of NH3 applied
  • NH3 PER MINUTE: displays the total lbs. (kg) of NH3 applied per minute
  • TANK: displays lbs. (kg) of NH3 remaining
  • RATE: displays lbs. (kg) of actual "N" applied per acre (hectare)
  • AREA: keeps a running count of the total acres (hectares) worked
  • DISTANCE: displays distance traveled in feet (meters)
  • AREA/HOUR: displays current work rate in acres per hour (hectares per hour)
  • SPEED: displays ground speed in miles per hour (kilometers per hour)



The GSC-1000

Automatic Rate Controller for Granular Spreader Systems

The new GSC-1000 from Micro-Trak is a low-cost high performance easy-to-use dry rate controller that not only controls product rate, but also has an optional RPM input. Once the spreader constant has been determined by a simple calibration procedure, product density or gate setting can be changed by simply entering calibration and changing the density or gate height; no need to re-calibrate the spreader constant.


  • 3 independent Area and Volume counter pairs that can be used to record your daily, weekly & seasonal totals.
  • No Flow and No Speed messages to quickly alert operator of fault.
  • Displays Bin Level so operator always knows how much product is remaining (also has settable low bin alarm).
  • Monitors spinner RPM for accurate spread pattern. Displays Weight per Minute of product being applied.
  • Displays distance in feet for quick verification of Speed input accuracy.
  • Displays Rate of product applied down to one hundredth of a pound for ultra low rate accuracy.
  • Automatically stops apron if No Flow is detected and alerts operator to prevent over applying product.
  • Can be configured to control either the apron rate or spinner RPM.
  • Spreader Constant, once this has been determined, it never needs changing unless drive gear ratio is changed.
  • Gate Setting, when the gate height is changed simply adjust this setting to match, can be adjusted in one tenth of an inch increments.
  • Density, when the density of the product changes simply adjust this setting, can be adjusted in one tenth of a pound per cubic foot.
  • Product rate regulating valve can be used as shut off valve if the Auto Off feature is activated.
  • Bin level set point can be adjusted to alert operator when bin level is low.



MT-3405D

Dual Channel Automatic Rate Controller

The New MT-3405D Dual Channel Automatic Rate Controller simultaneously controls the application of TWO products from one controller!


  • Easy to use, eliminates cab clutter with one unit!
  • System operates in either "standard" mode where channel 2 controls a single independent boom with programmable width, or "injection" mode where channel 2 responds to channel 1 boom switches and widths
  • Heavy-duty console with built-in boom controls
  • Controls any combination of liquid, granular or NH3 products
  • Built-in capability for VRA
  • Records area and volume in 3 independent pairs of counters for each control channel so individual jobs may be tracked
  • Tank counter shows amount remaining in tank for each channel
  • Low Tank Alarm: "Fill" flashes in display when tank level is low (settable)
  • Troubleshooting enhancements including "No Speed" and "No Flow" messages
  • Independent on-the-go rate adjustment for each control channel in Auto control mode
  • Each channel has independent auto/manual control for spot treatments
  • Minimum flow feature to ensure proper application pattern as ground speed slows to extremes
  • Precise rate control regardless of field conditions
  • Flow-based control
  • Controls electric and hydraulic valves/motors
  • Master hold turns both channels ON or OFF simultaneously
