Abstract

This eccentric bushing is designed to save mechanics/operators of agricultural planters money and time in replacement of common bushings formerly employed in these machines. Primarily, the bore of this bushing is eccentric/skewed on its axis and is received on a pin of a frame of a planter, and by its manual adjustment will cause a rubber depth gauge wheel to re engage a disc of the planter to keep the disc sharp.

Claims

1. An eccentric bushing assembly for worn out machine adjustment of an agricultural planter comprising an eccentric bushing formed with a through-bore eccentric and skewed with a longitudinal axis of the bushing;

a mounting sleeve for receiving the bushing;

a mounting pin having an enlarged mounting end and an internally threaded opposite end for insertion into the bushing through-bore; and

, a locking bolt threadably engageable in the threaded end of the mounting pin thereby to lock the mounting bushing between the mounting sleeve and the mounting pin, whereby slackening the locking bolt enables adjustments of the rotational position of the eccentric bushing relative to the mounting sleeve.
