Control Valve | Drive Motor

HD 4180


The DICKEY-john® HD 4180 is a combination hydraulic motor and proportional hydraulic valve intended for use on planters and air seeders to rotate the seeding shafts, instead of using ground-driven gear boxes. The HD 4180 is designed to be used in conjunction with a ground speed control system to assist in the control of manual or variable rate adjustments to the seeding population per acre while moving through the field. 

Features and Benefits:

  • 0-4 gpm hydraulic flow delivers 4-180 rpm at 1,400-inch pounds of torque
  • Eliminates ground drive system to rotate seeding shafts
  • No need to change sprocket rations or gear box settings to adjust population
  • Install up to four units in series to control multiple planter sections or fertilizer application
  • Interface with a ground speed control system for variable rate control of planter and fertilizer application in the field
  • Manual override of hydraulic flow in the event of electrical failure
