HD Spike & Reel Settings
Refer to Figure 12
9.
On the hd spike drag, start with 5 links hanging from the
chain
in drag arm bottom slot. (This is the starting
point for worst conditions). The cleaner the ground, the
shorter the pull chain may be pulled up. Always make
sure that the drag is never pulling off of the hang chains
. If so, shorten pull chains.
10. Adjust nut to where spring is just making contact
with front plate .
11. Turn nut another 1” further on spring rod to set pre-
load on spring .
12. Lengthen turnbuckle to adjust front mini shank to
run more aggressive and shorten to run more passive.
13. Be sure the fold catch assembly is aligned 3 7/8” from
back of rear angle iron of fold catch to rear of arm as
shown.
Coil Tine Settings
Refer to Figure 13
14. On coil tine drags start with the top eyebolt centered.
Then level drag mainframe by changing position of
leveling bolts . There are two holes in the arm and four
in the mainframe. One of these will get you where you
need to be to be level. To lay teeth back, remove the clip
pin
on each end and move strap adjustment by push-
ing the handle forward. The strap has 5 holes that will
let you lay the teeth back several degrees. If it is desired
to set one row, usually the first, different than the rest as
far as the angle is concerned, it can be adjusted individ-
ually by loosening the u-bolt and set-screw on each end
of the drag bar. Down pressure on the drag is achieved
by lengthening the eyebolt
on the top bracket.
Depending on the amount of down pressure, you may
need to re-level the mainframe.
Reel Settings
15. If a reel is added, adjust the amount of down pressure by
either shortening the eyebolt for less pressure or length-
ening for more pressure.
