GRAHAM FORCE – The World’s First Electric Depth Control System 

Our patent-pending electric down pressure system utilizes self contained hydraulic chamber electric actuators that are controlled using our wireless electronics.  We eliminate the need for hydraulic hoses and control harnesses, but offer robust and fast responding depth control to ensure your seed placement depth is consistent and accurate no matter the terrain and ground you work in.

We have built this retrofit kit with simplicity in mind, utilizing the existing parallel linkage and adopt our mounting kit to work on any brand of planter.  Designed to pair with our Graham Command Pro electric seed meter drive solution, the Graham Force can also be used as a stand-alone product.  We have kits for all major planter brands including

  • John Deere
  • Case IH
  • White
  • Kinze
  • Great Plains

The Operator has the ease of using a Wireless Android Tablet to configure the default down pressure on each row unit as well as monitor performance during planting.  Our system uses a load pin on the gauge wheel for feedback to adjust pressure on the gauge wheel dynamically as the planter goes through the field.

Key system features include:

  • Elegantly Simple – 4” Electric Actuator with 100% wireless control
  • Robust Capabilities – Offers over 1,000 pounds down pressure
  • Android Tablet Control – 100% Wireless monitoring in cab using the Graham Command Pro Android Tablet
  • Individual Row Unit Management – Instantly adjusts pressure to manage planting depth
  • No Hydraulic Hoses – Eliminates the headaches of hydraulic hoses
  • No Air Bags – More responsive than Pneumatic Down Pressure
  • Quick Response – Each control board samples 125 times/second; each actuator able to adjust up to 500 LBs/second
  • Low Power Requirements – Each actuator control is designed to require less than 4 amps under normal conditions
  • Replaces Springs – Replaces the existing springs on your planter
  • Easy Install – Simple and Intuitive universal mounting kit
  • Any Row Unit Brand – Installs on any brand of row unit
  • Single Harness – Only harnessing required is power supply
  • Versatility – Works on any planter brand or planter type
