Abstract
A seeding apparatus includes an implement frame mounted on wheels and a plurality of furrow openers mounted on the implement frame. A primary air seeder cart is pivotally connected about a vertical implement pivot axis to an implement hitch on the implement frame, and an implement pivot limiting system is operative to limit a degree of pivoting of the primary air seeder cart about the implement pivot axis with respect to the implement frame to a selected degree chosen to reduce bending of conduits. A secondary air seeder cart can be pivotally connected to a cart hitch on the primary air seeder cart about a vertical cart pivot axis and an cart pivot limiting system is operative to limit the degree of pivoting of the secondary air seeder cart about the cart pivot axis.
Claims29
A seeding apparatus comprising:
- an implement frame mounted on wheels for travel in an operating travel direction, and a plurality of furrow openers mounted on the implement frame;
- a primary air seeder cart pivotally connected about a substantially vertical implement pivot axis to an implement hitch mounted on the implement frame;
- and
- an implement pivot limiting system operative to limit a degree of pivoting of the primary air seeder cart about the implement pivot axis with respect to the implement frame to a selected degree chosen to reduce bending of conduits,
- wherein the implement pivot limiting system comprises a pivot control configured to selectively activate an actuator to pivot the primary air seeder cart to the right and/or the left with respect to the implement frame,
- and wherein the pivot control is configured to be movable to a float position where the actuator exerts no force.
