Dual Weight Kit
If unusual soil conditions require more weight for coulter
penetration, one or two weight bracket kits are available,
each kit containing tow brackets (one for each wing). The
brackets attach to the wing mainframe, and accept up to
five standard “suitcase” tractor weights, approximately
500 lbs (227 kg) per bracket or 1000 lbs (454 kg) per kit.
The empty weight of the kit itself is 121 lbs (55 kg), or 61
lbs (28 kg) per bracket.
The weight kit is field-installed, and does not include
weights. See also:
“Install Weight Brackets (Option)” on page 19, and
“Frame Weight” on page 68
Frame-Mounted Coulters
All 3N-40 drills support frame-mounted coulters. The
3N-4010HDF alternatively supports unit-mounted
coulters (page 122). It is not possible to install both types
on the same drill.
Frame-mounted coulters are recommended for heavier
no-till conditions and rocky soil. They are independent of
row-unit down-force and may be set to different (usually
higher) force levels.
Because the weight of the drill is used to deliver both
frame-mounted coulter and row-unit opener/press-wheel
down-force, extra weights may be required with
frame-mounted coulters. Each coulter itself adds 61 lbs
(28 kg) to the drill. See page 26 for weights of various
drill confgurations.
When ordered with a new drill, frame-mounted coulters
are factory-installed. They may also be ordered for field
installation. Each kit equips an entire drill.
See “Frame-Mounted Coulters” on page 63 for adjust-
ments.

Transport Hazard: Adding more than the recommend weight
to the drill frame could cause a tire to blow during transport,
leading to a serious road accident and personal injury. Do not
add more than 2000 pounds (907 kg) to the drill frame.
