Abstract

An agricultural implement has a ground opening and closing assembly that readily allows for adjustment of a pair of closing disks into different, discreet or infinitely variable, home positions that vary in height, disk spacing and fore/aft dimension. In one form, a pair of disk mounts have a pair of mounting receptacles for each support arm. Each support arm is configured to be inserted into one of the receptacles to set the height and fore/aft position of the associated closing disk. Mounting openings can be formed in the disk mounts and the support arms, and a simple pin mechanism received in aligned mounting openings can effect manual disk adjustment without tools. The disk mounts and the support arms can have multiple mounting openings spaced apart differently from the ground opening member to vary the spacing between the closing disks.

Claims19

Dependent claims

A disk assembly for an agricultural implement having a ground engaging implement coupled to a support frame, the disk assembly comprising:

a first bracket coupled to the support frame on a first end and defining a pivot axis through a second end;
a first disk rotatably mounted to a first support arm;
a first mounting assembly pivotally coupled to the first bracket along the pivot axis;
a first plurality of receptacles included in the first mounting assembly, the first plurality of receptacles providing a first plurality of mount openings, each of the first plurality of mount openings being configured to couple the first support arm to the support frame;
and
a first mounting pin releasably coupled to the first mounting assembly through one of the first plurality of mount openings to couple the first support arm to one of the first plurality of receptacles of the first mounting assembly;
wherein the first plurality of mount openings are disposed at different positions with respect to the ground engaging implement so as to selectively mount the first disk in a plurality of different home positions with respect to the ground engaging implement, the plurality of different home positions for the first disk varying fore/aft distance, height and lateral spacing of the first disk with respect to the ground engaging implement;
further wherein, the first mounting assembly pivots about the pivot axis.

A disk assembly for an agricultural implement having a support frame, the disk assembly comprising:

a ground opening member coupled to the frame;
a first mounting assembly coupled to the frame and having a first pair of receptacles opening to a first side of the ground opening member;
a second mounting assembly coupled to the frame and having a second pair of receptacles opening to a second side of the ground opening member opposite the first side;
a first closing disk at the first side of the ground opening member coupled to the first mounting assembly by a first support arm configured to be positioned partially within one of the first pair of receptacles;
a second closing disk at the second side of the ground opening member coupled to the second mounting assembly by a second support arm configured to be positioned partially within one of the second pair of receptacles;
fasteners for releasably connecting the first support arm to the first mounting assembly and connecting the second support arm to the second mounting assembly;
wherein the first and second mounting assemblies are configured with a plurality of mount openings for coupling the fasteners thereto;
further wherein each of the plurality of mount openings are spaced differently from the ground opening member for varying the spacing between the first closing disk, the second closing disk and the ground opening member;
and
further wherein each of the plurality of mount openings are used to set different home positions for the first and second closing disks to vary fore/aft distance, height and lateral spacing between the first closing disk, the second closing disk and the ground opening member.

7 more elements

An agricultural implement having a ground opening member coupled to a support frame and a disk assembly comprising:

a return assembly coupled to the support frame;
first and second mounting assemblies coupled to the return assembly for pivotal movement with respect to the support frame, the first mounting assembly having a first pair of mounting receptacles opening to a first side of the ground opening member and the second mounting assembly having a second pair of mounting receptacles opening to a second side of the ground opening member opposite the first side, wherein the first pair of mounting receptacles or the second pair of mounting receptacles of each of the respective first and second mounting assemblies are spaced apart in a fore/aft dimension and a height dimension, and wherein the first mounting assembly includes a first plurality of mount openings that communicate with the first pair of mounting receptacles and the second mounting assembly includes a second plurality of mount openings that communicate with the second pair of mounting receptacles;
a first closing disk and a second closing disk mounted to a first support arm and a second support arm respectively, the first and second closing disks spaced apart on the respective first and second opposite sides of the ground opening member, the first support arm being configured to be received in one of the first pair of mounting receptacles and the second support arm being configured to be received in one of the second pair of mounting receptacles, wherein the first support arm has a first support arm mount opening defined therethrough and the second support arm has a second support arm mount opening defined therethrough;
and
a first mounting pin configured to be received in the first support arm mount opening and one of the first plurality of mount openings of the first mounting assembly for releasably securing the first support arm in one of the first pair of receptacles of the first mounting assembly;
and
a second mounting pin configured to be received in the second support arm mount opening and one of the second plurality of mount openings of the second mounting assembly for releasably securing the second support arm in one of the second pair of receptacles of the second mounting assembly;
wherein, the respective first and second mounting pins are used to set a home position of each of the first and second closing disks at a particular fore/aft distance, height and lateral spacing with respect to the ground opening member.
