ABSTRACT:
An upstanding housing is provided and mounted in trailing relation to a depending tool shank by generally horizontal upper and lower pivot links having their forward ends pivotally supported from the tool shank and their rear ends pivotally supported from the housing. A driven power shaft is journaled in the upper portion of the housing and an output shaft is journaled in the lower portion of the housing. A chain is trained about sprocket wheels mounted on the shafts and has a spring biased idler sprocket wheel is engaged with one reach thereof for tensioning the chain. A rod weeder shaft has one end supported from the output shaft and additional laterally spaced depending tool shanks include trailing journal structures mounted for limited vertical shifting relative thereto and the rod weeder shaft has longitudinally spaced portions thereof journaled by the journal structures. Front-to-rear extending connecting links are pivotally connected between the journal structures and the corresponding tool shank lower end portions and the journal structures include laterally spaced mounting flanges having vertically spaced transverse bores formed therethrough in which pivot pins are received for selective vertical adjustment of the pivot connections between the journal structures and the rear ends of the links and the link rear end portions include the pending tang portions oscillatable with the links to prevent soil buildup between the mounting flanges.
