Brinly PP-1200 - Upper Link; Depth Adjustment; Leveling Adjustment; Coulter Adjustment

DEPTH ADJUSTMENT - The plow point pitch or suck is
controlled by 3-point hitch top turnbuckle link. Shortening
upper l ink will cause plow to go deeper; lengthening upper
link will cause plow to run shallow . With upper link ad-
justed as in Fig. 5, plowing depth should be 5"-6 " when
tractor wheels are running in prev iously plowed furrow. Al -
ways readjust gauge wheel after changing plowing depth.
Loosen two bolts attach ing plow bottom to standard; turn
land adjust ing bolt clockw ise two turns; ret ighten plow
bottom attaching bolts securely. Repeat adjustment as
necessary until plow follows correctly. Plow is prope rly
landed when running clearance between lower links and
tires is approximately equal and upper link extends
straight behind tractor.
LEVELING ADJUSTMENT - When tractor running in pre-
viously plowed furrow , at desired depth and width of cut,
stop tractor with plow in ground and view plow from rear.
Plow standard should appear near vertical from g round . If
plow standard appears to be leaning to the right , raise R.H.
hitch link by turning R.H. lift link control clockwise , or lower
L.H. link by turning L.H. lift link control counter-clockw ise.
The
opposi te ad justments would apply when plow standard
leans to the left .
COULTER
ADJUSTMENT - Coulter should be adjusted to
slice 2 "-3" deep. While making this adjustment, the coulter
limit stop pin should also be set to prevent coulte r from
swinging into plow beam or bottom. If properly adjusted,
coulter will be free to swing outward a lim ited amount from
beam, but will not be free to swing in to touch plow beam or
bottom .

WHEN TO PLOW - Make sure the ground is in proper
plowing condit ion before start ing. Never plow when the
soil is wet . If it is too dry , it wil l be difficult for the p low to
penetrate the soil. Avoid low places , old roadways, paths
and other plces where the soil is overly packed. Expect to
have
trouble with a thick sod which has not been plowed in
several years.
However , by finding the correct setting of the
plow and hitch, you should be able to do a satisfactory job
under most cond itions. H igh weeds or grass should be cut
down with the rotary mower before plowing .
LANDING
ADJUSTMENT - The plow bottom w ill react
s imilar to a rudder wh ile ground engaged . If plow po int is
too fa rf rom left of beam, plow will tend to over cut and leave
a ragged furrow
wal l. This cond ition can be read ily correct-
ed by
making the following adjustment:

TO BEGIN PLOWING - This plow usually works best at a
depth of appro x imately one -half its w idth ; i.e. 12 " plow :
6 "-7" . To turn plow po int into ground, lower plow w ith
hydraulic lift lever . Be sure lift control is in float position.
Note : In some soils it may be necessary to shorten top
hitch link to get satisfactory penetration on first and
second plowing passes .
After making first two plowing passes, adjust top hi tch l ink
so that landside heel runs from level to )14" up from bottom
offurrow. See FIG . 8 . After the dead furrow has been mad e,
the plow will level off by runn ing right tractor wheels in
previous ly plowed furrow . Variation in plow depth will
affect level attitude of plow . (See leveling instructions.)
