Preparation and Setup
This section helps you prepare your tractor and 7000
Series II Disk Harrow for use, and covers tasks that need
to be done seasonally, or when the tractor/Disk Harrow
configuration changes.
Before using the Disk Harrow in the field, you must hitch
it to a suitable tractor, inspect systems and level the Disk
Harrow. Before using the Disk Harrow for the first time,
and periodically thereafter, certain adjustments and
calibrations are required.
Prior to Going to the Field Checklist
Complete this checklist before routine setup:
❑ Read and understand “Important Safety Informa-
tion” on page 1.
❑ Check that all working parts are moving freely, bolts
are tight, and cotter pins are spread.
❑ Make sure your tractor horsepower matches the
implement you are pulling. This is important so the
implement can do the best possible job.
❑ Clean all hydraulic couplings and connect to tractor
as shown on page 14.
❑ If machine is folded, make sure the fold stop valve
located on the front of the machine at the bulkhead
bracket is open. Make sure no one is under the
wings and slowly unfold the unit.
❑ Check again for hydraulic leaks and watch that
hoses do not get pinched in hinges, wing stops, etc.
❑ After the machine is completely unfolded, raise and
lower the Disk Harrow several times to purge air from
the hydraulic system. Again check for hydraulic leaks
and tighten or replace if necessary.
❑ Check safety chain hookup. Make sure all warning
lights are hooked up and functioning correctly.
❑ Check that all grease fittings are in place and lubri-
cated. See “Lubrication” on page 30. The hubs will
come pre-greased and will not need greased at this
time.
❑ Check that all safety decals and reflectors are cor-
rectly located and legible. Replace if damaged. See
“Safety Decals” on page 5.
❑ Inflate tires to pressure recommended and tighten
wheel bolts as specified. See “Tire Inflation & War-
ranty” on page 33.
❑ Refold the machine slowly. Turn the fold stop valve to
the shut postion to lock the fold hydraulics. Put trans-
port locks in place. Always use the transport locks
when moving from field to field and while in storage.
❑ You are now ready to go to the field.
