Unit Mounted Coulter

CAUTION:

A44347
A44347-UN-16DEC97

Avoid crushing injury or death from a falling implement. Install service locks before performing any service or adjustments under a raised machine:

Shift tractor to “Park” or set the parking brake, stop engine, and remove the key.

CAUTION: Coulter blades are sharp. Use gloves when handling blades.

IMPORTANT: Bottom edge of coulter blade is placed approximately 10 mm (3/8 in.) up from bottom edge of seed openers in normal conditions. (Check this dimension with machine in planting position on any level surface.) The force required for penetration and the help to maintain a constant seed depth is minimized.

As coulter blade wears, adjust coulter depth.

IMPORTANT: An option in heavy straw is to position bottom edge of coulter blade under bottom edge of seed openers, but doing so can affect seed depth.

A - Cap Screw

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 depth is controlled with the opener gauge wheels, weight adjustment, and cap screw (A). As blade wear occurs, loosen cap screw (A), lower arm to next notch and tighten nut.

If the soil is dry on top but moist underneath and the coulter blade is lifting mud to the surface, mud can accumulate on the gauge wheels and alter the seed depth. Either raise the coulter slightly, use a less aggressive blade, or remove coulter in these soil conditions.

Down force springs are recommended with this attachment.

A - Cap Screws

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 from the direction of travel do the following:

  • Remove cap screws (A).
  • Add washers, as required, between back surface of coulter casting and front of planting unit.
  • Reinstall cap screws (A).
