Adjust Hydraulic Fan Speed

NOTE: Prior to fan speed adjustment, allow tractor hydraulic oil to warm up to operating temperature. Cold oil causes slower fan speeds.

    The recommended fan speed is:

  • 4200 rpm for 4 and 6 m versions.
  • 3600 rpm for 3 m version (3300 rpm for fine seed).

Adjust speed at valve (A) if the tractor does not have an SCV with variable flow rate. A gear-type motor (B) drives the fan shaft.

Fan must coast down gradually when the oil supply is shut off at the tractor to avoid damage. A check valve permits oil to flow in one direction.
