Hydraulic Hose & Light Harness
Refer to Figure 6
Note: The light harness
and hoses will be pre-assembled
and hooked up to cylinders, except for the wing cylinders.
They will need to be routed along hitch assembly
as
shown. They will be rolled up and fastened to center
frame during shipment. Untie hoses and light harness
with tractor couplers.
12. Remove the 1x6 1/2 Gr. 8 hex bolts and slide hitch pole
forward. The hitch pole should be extended far
enough to prevent the seedbed conditioner from contact-
ing the host machine during turns.
13. Unroll light harness and hoses and route them along
left side of hitch assembly , through hitch pole tube
and up through hose holder as shown. Leave about 3
foot of hose and wire harness in front of hose holder. Re-
install the 1x6 1/2 Gr. 8 hex bolts
, 1 lock washers and 1
nuts.
14. Remove hose clamps and route hoses and light har-
ness across blocks and re-install hose clamps . Snug
up the hose clamp bolts but do not pinch the light har-
ness or hoses.
15. Attach the hose wraps around hoses and wire harness
and be sure they do not drag on ground or get pinched
when turning.
Wings
Refer to Figure 7
16. Use fork truck or overhead hoist to move the wing assem-
bly closer to center section. Set wing assembly on
stands if available. Leave wing assembly folded in ship-
ping position until wings are installed and hydraulic system
is charged.
17. Remove 1x7 hex bolts and align holes in wing frame
assembly with holes in center frame and re-install 1x7
hex bolts , secure with 1 nylon lock nut. Bolts must be
installed so the head of the bolt is in the hex bolt stop.
Hinge bolts should be drawn down snug but do not torque
as wing needs to pivot freely.
18. Attach base end of outer wing cylinders to lug on inner
wing frame with 1x3 11/16 pins , secure with
1.5x1.00x0.75 machine washer and 3/16x2 cotter pin.
19. Do not attach rod end of fold cylinders until system has
been purged of air or connect hoses to tractor until hoses
are hooked up to cylinders, See “Purging Hydraulic Sys-
tem” on page 10.
