Draft control
The draft control lever (1) sets the desired depth of the
attached implement. Draft control is best when using im-
plements that operate in the ground, such as plows, har-
rows, or cultivators. The draft loading on the implement
increases and decreases as the working depth or the soil
resistance changes.
To set the draft control, move the position control lever
(2) to the full forward position. Then set the implement
draft depth lower by moving the draft control lever forward,
or set implement draft depth higher by moving the lever
rearward.
Implement depth will be proportional to draft, depending
on the soil conditions. With draft control, the lift keeps the
tractive effort steady automatically.
You can limit the range of manual draft lever operation by
moving and tightening the stop (3).
Combined draft and position control
You can use Draft and Position Control together to operate
in Draft Control but prevent the implement from sinking
excessively when soil conditions change. First set the
draft control lever (1) with the position control lever (2)
fully forward. Then move the position control lever back
until the link arms start to rise. The position control lever
sets the lowered position of the hydraulic lift.
Response control
The response control knob (1) varies the speed of drop of
the lower links.
Clockwise rotation -- Decreases speed of drop
Counter-clockwise rotation - Increases speed of drop
NOTICE: To lock implements in transport position when
driving on road, fully raise Position Control lever (2), see
5 and screw in (rotate clockwise) knob (1), see 5.
