BOLT TORQUE
Mounting bolts and hardware
Before operating the Viper opener for the first time, check to be sure that all hardware is
tight. Check all hardware again after approximately 50 hours of operation and at the
beginning of each planting season.
All hardware used on the Viper opener is Grade 5 unless otherwise noted. Grade 5 cap
screws are marked with three radial lines on the head. If hardware must be replaced, be
sure to replace it with hardware of equal size, strength and thread type. Refer to the
torque values chart when tightening hardware.
Important: Over tightening hardware can cause as much damage as when under
tightening. Tightening hardware beyond the recommended range can
reduce its shock load capacity.
The chart below is a guide for proper torque. Use it unless a specified torque is called out
elsewhere in the manual.
Torque is the force you apply to the wrench handle or the cheater bar, times the length of the
handle or bar.
Use a torque wrench whenever possible.
The following table shows torque in ft. lbs. for coarse thread hardware.
Lubricate all bearings and moving parts as assembled and make certain that they work freely.
WARNING: Never work around the toolbar/implement while in a raised position without using safety
lockups.
CAUTION: The Viper opener and its attachments are very heavy. Pay extra attention to lifting techniques
while handling and or maneuvering the opener during assembly. Failure to do so may lead to
personal injury.

INSTALLATION INSTRUCTIONS
STEP 1. Attach the shank to the coulter assembly using two ½” x 3” bolts and lock
washer.
STEP 2. Assemble the 5/8” jam nuts to the 5/8” set screws, and then insert the setscrew
into the 3000-300 clamp castings. Next, insert the ½” bolts into the 3000-300 clamp
castings and assemble to a clamp plate.
7
INSTALLATION INSTRUCTIONS
STEP 3. Install the clamp assembly onto the shank; slightly tighten a 5/8” set screw to
temporarily hold the clamp to the shank. Insert the 3/8” x 2” bolt through the top hole of
the shank; secure it with the 3/8” lock nut.
STEP 4. Attach the coulter/shank/clamp assembly to the fertilizer toolbar using the 3000301 wedge, clamp plate and ½” lock nuts.
8
INSTALLATION INSTRUCTIONS
STEP 5. Move the coulter assembly to the desired distance away from the seed furrow
2”-4”. Then fully tighten the ½” clamp bolts. Torque the bolts to 90 ft. lbs. NOTE: During
the season, check the tightness of the clamp bolts daily.
IMPORTANT: Never locate the opener to place fertilizer closer than 2” to the row.
STEP 6. Setting the height of the coulter assembly, loosen the 5/8” setscrew and raise or
lower the coulter/shank assembly to the desired height. Tighten the setscrews to hold the
coulter/shank assembly in place. NOTE: Field adjustment of the shank position will be
required to accurately place the fertilizer at the desired depth. Factors affecting fertilizer
depth: toolbar height, shank adjustment, gauge wheel adjustment, spring pressure
adjustment, and soil tilth. When the coulter shank is adjusted to the desired height, triple
tighten (tighten, loosen, tighten, loosen, tighten) the 5/8” setscrews so that the cup point is
properly seated into the coulter shank.
NOTE: Regularly check the tightness of the setscrews.

OPERATION
VIPER FERTILIZER OPENER
The Viper II single disc fertilizer is designed for use in conventional, minimum and no-till
field conditions. Placement of fertilizer with the single disc fertilizer opener is
recommended at 2”-4” from the row. The opener is designed to hold the blade at a set
angle so the knife and fertilizer tube operate in the shadow of the blade. NEVER locate
the opener to place fertilizer closer than 2”. Maximum operating depth (16” blade - 31/2”)(18” blade – 4-1/2”). Check the fertilizer hose clearance after adjusting opener
depth. Torque the setscrews and jam nuts to 100 ft. lbs.
WARNING: Operating the Viper opener in soils containing many large rocks is not
recommended. The opener’s upper movement limit stop is incapable of supporting the planter
frame weight as the opener rides up over large rocks.
ADJUST KNIFE TO BLADE CONTACT on each opener so the blade will turn by hand
with slight resistance, but will not coast or freewheel. In loose soil the knife adjustment is
critical. If adjustment is not maintained, soil or residue may wedge between knife and
blade, resulting in the blade not turning. Because of blade run out, rotate the blade one
full revolution after adjustment. Re-adjust knife as needed. Never strike the knife with a
heavy object or damage may occur.

OPERATION
STEP 1. Check/Set the planter frame height to the manufacturer’s recommendations.
