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 agricultural vehicle includes a frame, a wheel supporting the frame, and a rockshaft coupled to the frame and operable to pivot with respect to the frame. The rockshaft has an outer surface, an inner surface and an open end. An internal end cap is positioned on the open end of the rockshaft. The internal end cap has an inner surface and an outer surface. The inner surface of the internal end cap contacts the outer surface of the rockshaft. An external end cap is positioned on the open end of the rockshaft and contacts the outer surface of the internal end cap. A fastener connects the external end cap to the frame to retain the external end cap on the rockshaft.

A mounting structure for mounting a pivot arm to an implement has a cylindrical member, an adjusting sleeve, and a mounting bolt extending through the cylindrical member and adjusting sleeve to fix the cylindrical member and adjusting sleeve together. The cylindrical member extends through a bore of a bearing housing for rotation within the bearing housing. The adjusting sleeve has a threaded external surface. A disc spring is positioned on the adjusting sleeve. An adjusting nut is threaded onto the threaded external surface of the adjusting sleeve. The adjusting nut can be tightened to compress the disc spring to create a lateral bearing force against the bearing housing. The bearing housing can be integral with a pivot arm for mounting a gauge wheel assembly on a planter row unit, or the bearing housing can be a fixed part for mounting a pivot arm for a closing/press wheel on a drill.

An improved tilting bearing assembly (100) is provided that includes a support bracket and a tilting bearing; the support bracket and the tilting bearing, along with methods of replacing the same are also provided. The support bracket generally comprises a substantially planar upper portion lying in a first plane and having two opposing ends and a pair of elongated openings, each elongated opening extending in a first direction entirely through the upper portion of the support and having a closed end and an opposing open end, the closed end of each elongated opening being equidistant from respective ones of the two opposing ends; and two opposing leg portions, each leg portion projecting at an angle relative to the first plane, extending at respective upper ends of each leg portion from one of the two opposing ends of the upper portion and terminating at respective lower ends of each leg portion.

Adjustable gauge wheels are provided on a row unit planter adjacent the opening disc. The wheels are adjustable laterally for proper spacing adjacent the discs. The camber of the gauge wheels relative to discs is also adjustable. The lateral adjustment is accomplished via a wear bushing and pivot bushing extending into the wear bushing for each gauge wheel. A grease zerk is provided on the end of each pivot bushing to supply grease to the inside of the adjustment wear bushing. The camber adjustment is accomplished via a slot in the row planter frame and bolts extending into arms on a pivotal member.

A concentrated high-speed rigid hub allows for heavier planters, high-speed planting and seeding devices in multiple and multiple challenging applications such as No-Till, High CEC soils, Compact Soils, Moist soils, High concentrations of Stubble and or Bt crops, and Cover or Green crops with massive structured root systems. The hub is made of one of high strength forging steel and medium carbon cast steel, whereby the hub lessons hub flexing, hub bending, cracking and premature failure. The hub comprises rigid, heavy duty deep bosses or gussets which increase structural strength and maximize the strength of attachment points adapted for either bolts or rivets attachment to a blade or object.
