Abstract

An earth moving implement for forming a ditch when towed across ground includes a frame, a tow arm connecting the frame to a towing vehicle, wheels supporting the frame for rolling movement along the ground, and a blade assembly comprising a plurality of earth moving blades. The blades include two main blades arranged to be configured to extend rearwardly in opposing lateral directions from a blade apex of the blade assembly such that the earth moving blades diverge rearwardly from the blade apex, and two outer blades supported on the main blades respectively. The orientation of the outer blades relative to the main blades and of the main blades relative to the frame can all be adjusted while the bottom cutting edges remain level with one another to readily vary cutting width and the lateral direction of earth movement by the blade assembly as desired.

Abstract

When using a cross auger assembly on a crop harvesting header with a flexible frame having end frame sections pivotal relative to a centre frame section, mounting devices are coupled between the bearing housings at opposing ends of the cross auger assembly and the outer ends of the end frame sections. Each mounting device includes a first mounting structure fixed relative to the outer end of the end frame section, a second mounting structure fixed to a portion of the respective bearing housing, and a flexible mounting arrangement between the mounting structures to accommodate variation in lateral positioning of the bearing housings relative to the ends of the flexible frame as the flexible frame flexes over varying ground contours without requiring a telescoping shaft arrangement on the cross auger assembly.

Angled stripper for a cross auger on a crop harvesting header

      
Application Number 15007899

Status In Force
Filing Date 2016-01-27
First Publication Date 2017-07-27
Grant Date 2017-11-21
Owner AG Shield Ltd. (USA)
Inventor Mccrea, Thomas Edward

Abstract

The stripper is a flange member supported on the upright backboard of a crop harvesting header to span a gap between the backboard and a cross auger. The cross auger is supported above a draper on the header to assist in guiding the cut crop being conveyed by the draper to a central rear discharge of the header. The stripper flange member extends forwardly towards the cross auger at an upward inclination so as to be oriented at an angle of greater than 90 relative to a portion of the backboard of the header immediately below the stripper flange member. The stripper flange member is thus better oriented to guide cut crop which rises up the backboard to be deflected forwardly into the cross auger, instead of acting as a stop to accumulate cut crop thereon when the flange member is oriented perpendicularly to the backboard.

Abstract

A land roller implement includes a wheel aligned with the respective gap between the inner roller and the outer roller of each wing in which the wheel is pivotal between a packing position in the working position of the rollers and a transport position supporting the rollers in the transport position of the implement. The wings can also include a drive motor associated with each transport wheel to drive forward rotation of the wheel for displacing the wings from the transport position to the working position without displacing the implement in a rearward direction. A levelling beam attachment and a seeding attachment can also optionally be used on the land roller implement. Optional latchable brace members pivotally supported on the wings may provide additional support to the wings when using the levelling beam attachment.
