The T2R arid T4R Cultivators on a 3010 or 4010
Tractor are con- trolled by the rockshaft control
lever on the tractor. Push the lever for- ward
to raise the cultivator (both front and rear
rigs) and pull it to the rear to lower the
cultivator. Use the depth stop to regulate the
working depth of the cultivator. See your tractor
operator's manual.
The T2F and T4F Cultivators on the 2010 Tractor
are controlled by the rockshalt control lever.
Use the depth stop to regulate the working depth
of the cultivator.
When the tr actor hydraulic sys- tem is set for
independent lift arm operation and the front
rockshaft is split,' ' the front rigs canbe
raised and lowered independently. The rear rig,
however, is raised and lowered with the r
ight-hand rig.
When the T2 F or T4F Cultivator is on a 3010 or
4010 Tractor, the front rigs are controlled by
the re- mote cylinder operating levers, Use the
adjustable stop on the hydraul ie cylinder to
control the working depth of the cultivator. The
rear rigs are controlled by the rocks halt
control lever.
When the dual hydraulic sistem is set for
parallel lift arm opera- tion, all rigs are
raised and low- ered at the same time.
See your tractor operator's man- ual for
instructions regarding inde- pendent and parallel
lift arm opera- tion.
Install hydraulic cylinders and operate the
hydraulic controls as instructed in your
tractor operator's manual.

In order to do a good job of cul- tivating, the
front frames of the cul- tivator must be level.
To check to see if they are level stand in front
of the tractor and sight under the cultivator
frame bar and over the tractor axle.
If the frame is not level, move the uppe r truss
rod bracket away from the tractor to raise the
outer end of the frame. To lower the outer end of
the frame, move the upper truss rod bracket
toward the tractor.
FRAME BAR
To determine whether or not the front frames of
the T2 Cultivator are level, stand in front of
the tractor and sight along the cultivator frame
bar.
To move the frame forward, move the lower truss
rod bracket away from the tractor. To move the
frame to the rear, move the lower truss rod
bracket toward the tractor.
If it is not level, adjust the nuts on the truss
rods until the frame is parallel and level with
the tractor axle.
Be sure to tighten all nuts on the truss rod
brackets securely.

The gauge wheels determine the depth of
cultivation of the rigs on which they are used.
Set all gauge wheels to operate at the same depth.
Two types of gauge wheels are a vat 1ab l et h e
mastering gauge wheels shown below and the rigid
type shown at the right. Castexing gauge wkeel
Adjust the rigid gauge wheel for a working depth
of approximately 1 to 2 inches by loosening the
clamp bolt and moving the shank to the de- sired
position. The rigid gauge wheels should be
attached so that the wheels are under the rig
pipes as shown above and the shanks are
positioned to the right and left of the rig pipes
as shown below. Loosen the set screw and adjust
the cultivating depth by setting the gauge
wheels 1 to 2 inches above the floor or ground,

these rigs by hand until they come in contact
with the tractor. Then se- cure the upper collar
down next to the swivel. The upper collars on the
outside rigs of the T2 Cultivator (if gauge
wheels are not used) should be set the same
distance from the top of the rod to the swivel as
on the in- side rigs. On the T4 Cultivator, to
cheek the upper collars on the rigs controlled by
gauge wheels , lower the cultiva- tor until the
inside sweeps on the No. 1 and No. 2 rigs just
touch the floor. The upper collars should be
positione d approximately one inch above the
swivels. To recheck this setting, raise the
cultivator. If additional lift is desired,
lower these upper collars a slight amount. This
upper collar setting may require change in the
field, depend- ing upon the depth of
cultivation. CAUTION Once these upper col- lars
are set, be careful when chang- ing this setting
or the setting of the clamp on the cultivator
lift rods or lift pipes. Changing one or both of
these settings could cause the culti- vator to
damage the tractor when the cultivator is raised
or it could cause the cultivator not to raise
high enough.
SWIVELS
RIG RO To cheek to see if the rig lift rod
collars are set properly, raise the
cultivator. If raising the cultivator for the
first time, raise it slowly making sure the
rig pipes do not hit the lower rig links and
the shanks do not strike the underside of the
trae- tor. If the cultivator does hit at either
one of these places, loosen all the upper
collars on the rig lift rods and continue to
raise the cultivator to lts fully raised
position. E after the cultivator is fully
raised, additional lift is needed on the number

The rear rigs are operated by the tractor
rockshaft and controlled by the rockshaft
control lever.
If the rig stop does not hit the rear rig beam
after the rear rig is fully raised, lift the
outer rig by hand until it does and reset the
upper col- lars.

The height of Ult for rear rigs not equipped with
rear rig stops is controlled by the location of
the up- per collars on the rig lift rods and
lower collar on the center rig.
Rig stops When the rear rigs are equipped with
rear rig stops, the he ight of the outer rigs is
limited by these stops. When the rear rigs are
fully raised, the stop should come in contact
with the rear r ig beam.
The amount of down pressure on the outer rigs is
determined by the location of the lower collars
on the lift rods and the upper collar on the
center rig. Adjust them to secure the desired
penetration of the sweeps.
naisinherearriforthe first time, raise it slowly.
If the stop comes in contact with the rear rig
beam before the rear r igs are fully raised,
loosen the upper collars and continue to raise
the tractor rock- shaft as high as possible.
Lift the outer rear rigs by hand until the stop
comes in contact with the rear rig beam and set
the upper collar next to the eyebolt.
Depth of cultivation Depth of cultivation is
controlled by the upper collars on the outer rigs
and the lower collar on the drawbar mounted
center rig. Adjust upper collars on the outer
rig and the low- er collar on the center rig so
all the sweeps touch the floor at the same time.

Tool bar type rear rig
These instructions apply to the SOA Series
Rear Rig and to the 3- point hitch mounted
center rig on the other series of rear rigs. On
T2R and T4R Cultivators and T2F Cultivator on a
2010 Tractor, the working depth is controlled by
the length of the lift links on the 3-point
hitch. Check this length atter the working
depth of the front rigs has been deter mine d.
Use the adjusting cranks to lengthen or shorten
the lift links so the rear rig will oper- ate at
appr oximately the same depth as the front rigs.
Keep the tool bar level. On T2F and T4F
Cultivators on 3010 or 4010 Tractors , use the
ad- justable depth stop on the roekshaft control
lever to set the working depth.
The recommended length for the center link on
3010 and 4010 Trac- tors is 26 inches. The length
of the lift links on the 3-point hitch can be
changed for leveling if require d. NOTE With
the 50A 11 0B and 130B Series Rear Rigs, if
greater depth of cultivation is required, ii is
possible to more the center rig at- taching writs
to the upper set of holes.
leveling wigs After the upper collars on the out-
er rear rigs have been checked as explained on
page 11, lower the rear rigs. All the sweeps
should touch the floor at the same time. If they
don't, adjust the lift links and the center link
until they do. Timing rockshaft arm (T2R and T4R
cultivators only)
It is important that the rockshaft arms attached
to the tractor to op- erate the cultivator are
properly tlmed. If the cultivator is equipped
with a rear r ig and the arms are not timed, it
could mean the front and rear rigs will not
operate at the same depth. The rockshaft arm is
timed prop- erly when the timing mark on the arm
is in line with the timing mark on the tractor
rockshaft.
On the 3010 Tractors the recom- mended length A
for the right- and left-hand lift links is
26-3/4 inche s. On the 4010 Tractors the recom-
mended length 'A for the right- and left-hand
lift links is 28-1/2 inche s. On the 2010 Tractor
set the dis- tance at ' 'A to the minimum
setting as stated in your tractor ope
rator's manual.

Flexibility of rigs with gauge wheels UPPER
COLLARS
I FT ARM
LOWER WHEEL COLLARS
Adjusting down pressure on front rigs To
increase down pressure on the front rig shovels
or sweeps, raise the lower collars on the rig
lift rods. This will increase spring tension and
force the shovels or sweeps down- ward. (If no
down pressure is de- sired, loosen the collars
and let them slide to the bottom of the rod.)
The front rigs of the T4 Cultiva- tor equipped
with gauge wheels are designed to "float" with
the level of the ground.
When operating in the field, there should be 3/4-
to one- inch of space between the upper collars
on the rig lift rods and the lift arm. This will
allow the rigs to "float."
After the gauge wheels have been set so the
cultivator will cultivate at the desired
depth, this 3/4- to one- inch clearance is
controlled by the position of the upper
collars. When cultivating in the field, ad- just
the upper collars so there is the desired
clearance.
