Unit Mounted Coulter

The unit mounted coulter can be used to assist the TRU-VEE ™ opener to penetrate tough soil conditions and to cut or displace residue commonly found in reduced tillage conditions.

The coulter blade penetration depth is controlled with the opener gauge wheels and weight adjustment.

Down force springs are recommended with this attachment.

CAUTION: Raise machine and install service locks.

CAUTION: Coulter blades are very sharp. Use caution to avoid being cut.

IMPORTANT: Bottom edge of coulter blade should be approximately 10 mm (3/8 in.) above bottom edge of seed openers in normal conditions. (Check this dimension with machine in planting position on any level surface.) This dimension will minimize the force required for penetration and help maintain a constant seed depth. In heavy straw, penetration and cutting action may be improved if bottom edge of coulter blade is positioned slightly below bottom edge of seed openers.

As blade wear occurs, loosen nut (A), lower arm to next notch and tighten nut.

NOTE: Do not operate coulter deeper than seed opener when soil penetration is a limiting factor.

To adjust unit mounted coulter, proceed as follows:

Adjust coulter blade so it is directly in front of TRU-VEE ™ opener and is not running at an angle to direction of travel.

To align side-to-side, loosen cap screws (A) and slide coulter.

If coulter blade is running at an angle different than the direction of travel, remove cap screws (A) and add washers, as required, between back surface of coulter casting and front of planting unit.
