A gauge arm (and concomitant method of retrofitting an existing gauge arm) comprising an arm portion, a receptacle portion for receiving two or more sealed bearings, and two or more sealed bearings inserted into the receptacle portion. The receptacle portion is smooth bore, with the sealed bearings being press fit into same. The sealed bearings can be of different dimensions, such as one being a gauge wheel and closing wheel bearing, and one a round bore grain drill bearing. The receptacle portion then comprises a stop within the bore thereof.

An assembly for rotating a chain or toothed belt includes a shaft and a sprocket rotatably mounted on the shaft. The sprocket includes a plurality of teeth configured to engage the chain or toothed belt. The assembly further includes a shield assembly covering at least a portion of the sprocket. The shield assembly has an interior groove formed therein defining an enclosed interior space. Each of the teeth of the sprocket rotate through the enclosed interior space during a full rotation of the sprocket.

A vehicle light guard for protecting from damage an exposed vehicle light mounted on a fender of a tractor or on a fender of a similar type of vehicle. The light guard includes a tubular-shaped housing. The housing is adapted for receipt around the tractor light. The housing has sufficient width and diameter to cover the tractor light. The housing includes a light cord slit opening and a housing post hole adapted for receiving a threaded post attached to the tractor light and an electrical cord connected to a tractor battery. The post hole is center on a bottom portion of the housing. The threaded post and electrical cord are attached to a bottom of the vehicle light. The light cord slit opening and the housing post hole eliminate the need to disconnect the threaded post from the electrical cord, when attaching the tubular-shaped housing around the tractor light.

A scraper blade for a row unit of a planter. The scraper blade has a connecting portion that connects to the pivot hub of a depth-gauge assembly. The connecting portion connects to a blade portion. The blade portion is positioned in a gap formed between the pivot hub and the contact surface of the depth-gauge wheel. The scraper blade is connected to the depth-gauge assembly in a static and stationary position at a pivot point. As a pivot arm and the depth-gauge wheel move about in relation to the pivot point, the scraper blade maintains a fixed position at close tolerances with the depth-gauge wheel to remove soil and debris from the depth-gauge wheel.

A work vehicle includes row units. The row units each include an air pressure device configured to generate a pressure differential for retaining a commodity against a metering element to singulate and meter a commodity. The air pressure device includes an exhaust structure with a passage configured to direct an exhaust substance to the ground as the row unit travels.
