Landoll 5211 Grain Drill - Manual (Page 63)

OPERATION AND MAINTENANCE
4-33
Coulter Hitch (Option)
The Grain Drill may be equipped with an optional coulter
hitch (See Figure 4-30.) Coulters may be used to provide
additional tillage in front of the openers. The coulters
operate on a separate hydraulic remote which operates
independently of drill. A reference depth gauge is
located on the left side of the hitch for coulter depth.
Operation - The drill may be operated with or without the
coulters lowered to the ground. When turning with the
drill, the main drill lift hydraulics should allow the coulter
gangs to clear when turning without having to operate the
coulter hydraulics.
The amount of down pressure needed to operate the
coulters will vary with soil conditions, moisture and
residue. For accurate seeding depth you must adjust the
drill and coulter depths to match the current soil
conditions. Be careful not to operate the coulters too
deep, particularly in wet conditions. Coulters can
throw/remove too much soil in front of the opener that the
opener may not be able to properly close the seed
trench. Excessive coulter down pressure in dry/hard
conditions can raise or limit the travel of the openers
creating inconsistent planting depths.
