Disconnect Implement
The pull link that is the hitch between implement and
cart is replaced during this update. Removing the old link
early eases access for cart and implement updates.
Prepare Implement
29. Re-connect all harnesses and cables at cart hitch.
30. Raise and unfold the implement.
31. Set jacks or stands under the rear mainframe, under
the weights. Set their height to slightly higher than
the lowered position of the frame.
32. Lower the implement.
33. Set all hydraulic remotes to Float to relieve pres-
sure.
34. Connect jack to tongue. Unhitch tractor. Disconnect
all electrical connections between tractor and cart.
35. Adjust tongue height with jack until bottom edges of
hitch side plates are level.
Disconnect Primary Hoses
Refer to Figure 10
36. Verify that each primary air hose
, at the meter
end, is marked with the letter of the port to which it
is connected. If any markings are missing, write the
port letter on tape, and wrap it around the hose.
37. The the meter outlets, loosen eight:
800-180C 2 1/2 AIR HOSE BAND CLAMP
Slide these clamps several spirals onto to the
hoses . Re-tighten the clamps enough to pre-
vent loss. Pull the hoses off the meter outlets.
Equipment Damage Risk:
Disconnect all electrical connections between cart and tractor
prior to welding. Welding can induce high voltages and/or
high current flows that could damage sensors, WSMB and
WSMTs on the cart or implement.
