C Hydraulic control lever
This will control the pull of the 3-point implement. As the
load on the 3-point hitch changes due to various soil
conditions, the draft control system automatically
responds to these changes by either raising or lowering
the implement slightly to maintain a constant pull.
Set the implement pull with the hydraulic control lever.
C Draft ratio adjustment dial
Set the mode selector switch to the "DRAFT" position.
Turn the draft ratio adjustment dial to adjust to specific
application requirement. Make settings according to the
guidelines below.
