Figure 3.106: Cylinder Lock-Out Valve
–
Open Position
9.
Open lift cylinder lock-out valve (A) on each cylinder by
turning the handle to the open position (in line with
the hose).
10. To check float, lower the rotary disc pull-type to cutting
position, grasp the front corner of the rotary disc pull-type,
and lift; the weight should feel like approximately 45 kg
(100 lb.) at both ends.
11. Repeat adjustment procedures until the desired weight is
achieved at both ends of the rotary disc pull-type.
3.15.2
Cutting Height
Cutting height is determined by a combination of the cutterbar angle and skid shoe settings. Adjust cutting height for
optimum cutting performance while preventing excessive build-up of mud and soil inside the rotary disc pull-type, which
can lead to poor crop flow and increased wear on cutting components.
Lowering the skid shoes and decreasing the cutterbar angle increases the cutting height, resulting in higher stubble that
helps material dry faster. This may be desirable in stony conditions to help reduce damage to cutting components.
Raising the skid shoes and increasing the cutterbar angle decreases the cutting height, resulting in a shorter stubble. For
instructions, refer to
Adjusting Cutting Height, page 88
.
To choose a cutterbar angle that maximizes performance for your crop and field conditions, refer to
To minimize cutterbar damage, scooping soil, and soil build-up at the cutterbar in damp conditions, the float should be set
as light as possible without causing excessive bouncing. For instructions, refer to
.
