FIELD OPERATION
The following procedure should be used for field operation
of your Summers Diamond Disk & DT9530.
1. Remove wing safety lock pins and transport locks and
place in their storage positions.
2. Lower wings for field operation.
3. Level disk. The disk should be adjusted in a level area
of the field.
IMPORTANT!
All pressure must be removed from cylinders before adjusting
eyebolts. Rest Disk on top of the ground, shut tractor off and
relieve pressure by cycling remote lever.
A. First, level the center section (front to rear) by adjusting
the threaded eye bolts connected to each hydraulic
cylinder.
B. Second, level the wings with the center section again
by adjusting the threaded eye bolt connected to each
hydraulic cylinder.
After determining desired tillage depth, set depth control
plunger accordingly. Standard plunger hole spacing gives
5/16” cylinder stroke adjustment. By rotating plunger 90
degrees, a half step adjustment can be achieved. See
drawing below.
