Timing is accomplished by setting the top roller rotation
to mesh with the bottom roller using the timing notches
ground into the upper roller shaft. At the factory, the
key way on the lower roller shaft is aligned at the
1:30 position with notches ground into the upper
shaft at the 7:30 position
. A new chain should align
exactly in this position. A well-used chain will align in a
slightly different position as caused by longer chain
between roller sprockets. Refer to 6 AG SHIELD
RECON 200 GEAR DRIVE/ 540-1000 CHANGEOVER
page 21.
Set the top roller to have 3.3mm (1/8”) clearance
between lug and body of bottom roller, which is the
normal lowest setting with the machine height in a low
enough position that the 50 chains are not lifting the
upper roller. Rotate the rollers by hand to align the key
way of lower roller at 1:30 with notches ground into the
end shaft of upper roller at 7:30.
If this cannot be done, loosen the 80 chain drive at
spring tensioner, and jump chain over sprocket teeth
on lower roller until timing is correct. If timing cannot be
corrected with above procedure, then chain stretch has
caused upper roller to rotate counter clockwise (as
viewed from right side) in drawing and 3/4”
measurement will be decreased.
The chain should be replaced when 12 links of chain
exceeds 314mm (12 3/8”), an increase of 3% or 3/8”
from new length, in the opinion of some chain
manufacturers much sooner.
On serial numbers 1803113, top roller lug is 2.5mm
(1/16”) from barrel of bottom roller, and the spacing
from rear side of lug on bottom roller to front of lug of
top roller is 22mm (7/8”).
5.1.4. Roller adjustment vs crop damage
Refer to “D”. Ag Shield ReCon 200 drawing, pg. 20
Rollers are factory set to have 1/8” or less between the
lug of top roller and the round barrel of lower roller
when the roller Quik Set (part # 320230) is at minimum
thickness. This setting will give a very aggressive
crimping action required for fastest dry down. As the
forage becomes drier in swath, it may be desirable to
move the rollers further apart. The rollers can be
quickly raised 8mm (5/16”) to reduce crimp, or 16mm
(5/8”) to leave slight overlap of lugs on rollers, or
24mm (15/16”) to have only a fluffing action on the
swath.
If increasing the gap between the rollers does not
reduce crop damage to an acceptable level, consider
reducing the roller speed, by reducing PTO speed as
low as 60% of normal rpm.
5.1.5. Deflector adjustment
The adjustment of both top and side deflectors is
critical to obtaining desired results. Both of these
adjustments are in turn modified by changes in
forward speed
. A small change frequently causes
dramatic changes in swath shape, position, and
degree of inversion.
Refer to “E” on drawing following this section.
The top deflector changes the place of contact of the
swath on the side deflector. Use lower setting in high
(cross) wind conditions to keep material from
scattering excessively. Use highest setting to raise a
swath up and drop down on same location. Use any
setting to alter the degree of inversion of swath by
directing to different position on rear deflectors. In
hemp, a low setting will be preferred to keep heavy
stocks from scattering.
Side deflectors have a high degree of adjustment to
give maximum flexibility in machine usage. The factory
setting will allow swaths to be moved to left or right,
inverted, or the combining of two cuts into one swath,
while the 2
nd deflector provides wind protection for the
process. Swaths may be shaped into a high narrow
configuration by causing material to tumble off of the
end of deflectors, or left in original width by setting side
deflectors wide enough to avoid contact.
When operating in high crosswind conditions, consider
changing side deflector at each end of field to throw
primarily down wind.
If 2 conditioning passes (in grasses or hemp) are
anticipated, leave the swath wider during first pass,
narrowing during second, If bleaching of green color is
primary concern, consider more side deflector action to
invert and mix swath.
Swaths may be combined with your ReCon 200 by
driving one direction and throwing material to the side,
and returning on next swath deflecting second swath
on or beside the first. Two 12 ft swaths may be
combined using standard side deflectors, two 14 may
be combined into a single 28ft swath by using optional
extensions (part# 320301).
5.2. OPERATIONS
5.2.1. Lubrication-
Grease using standard high quality grease according
to the following table.
Do not over grease wheel and
roller bearings to the point where seals are damaged
or pushed out.
