1) SET COULTER DEPTH: On the 605NT, lower the drill until desired depth is
achieved and set the cylinder stop on the master cylinder. (The cylinder on the left
side of drill.). Raise the drill up and drive forward lowering the drill as you are
moving. Recheck the coulter depth and adjust, by doing this the coulter depth will
always return to the same depth.
On the 3P605NT the coulter depth is controlled by raising or lowering the front
drive wheel. Do not use the tractors three-point to raise the drill without adjusting
the drive wheel. The front drive wheel must always make contact with the ground or
seed skipping will occur.
A) If the cylinders are completely retracted and the coulters are not penetrating,
add weight to the drill. DO NOT re-adjust the coulter shanks, as lowering
the coulter shanks will not increase coulter penetration.
B) Coulter springs are preset at the factory giving the coulters an initial
operating force of 400+ lbs. This setting is adequate for most field
conditions. Re-setting the coulter spring shorter than 9¾ inches can cause
premature failure of parts.
