Abstract
An agricultural toolbar employs at least two wing assemblies for following the contour of the land in a working position and foldable to a transport position for transit on public roads. The principal use in working position benefits from having a wide range of movement to accommodate variations in land contours and soil types. The principal use in transport mode benefits from having a compact configuration to better meet road regulations. End-uses that condition cultivatable land at multiple locations will benefit from the toolbar.
Claims20
An agricultural toolbar comprising:
- a center support, said center support defining a first longitudinal axis and second longitudinal axis, said first longitudinal axis perpendicular to said second longitudinal axis;
- a first arm member having a first arm member aperture and pivotally attached to said center support about said second longitudinal axis;
- a second arm member having a second arm member aperture and pivotally attached to said center support about said second longitudinal axis;
- a latching mechanism having an alignment member having an alignment member aperture in general alignment with each of said first arm member aperture, said second arm member aperture and an alignment pin, and said alignment member being mounted to said center support;
- and
- a latching member having a latching pin in general alignment with said alignment member aperture, said first arm member aperture, and said second arm member aperture, and said latching member in slidable engagement with said alignment pin,
- wherein each of said first arm member and said second arm member has a wing assembly having a first support member and a second support member mounted thereto, a pair of stabilizer assemblies having a mounting member, and a movable member, said movable member mounted to said mounting member, and said mounting member mounted to each of said first support member.

An agricultural toolbar comprising:
- a center support, said center support defining a first longitudinal axis and second longitudinal axis, said first longitudinal axis perpendicular to said second longitudinal axis;
- a first arm member having a first arm member aperture and pivotally attached to said center support about said second longitudinal axis;
- a second arm member having a second arm member aperture and pivotally attached to said center support about said second longitudinal axis;
- a latching mechanism having an alignment member having an alignment member aperture in general alignment with each of said first arm member aperture, said second arm member aperture and an alignment pin, and said alignment member being mounted to said center support;

An agricultural toolbar for use with a tractor operating in a field and in transport, the agricultural toolbar comprising:
- a center support having a first end portion and a second end portion, said center support defining a first longitudinal axis and second longitudinal axis, said first longitudinal axis perpendicular to said second longitudinal axis;
- a first arm member having a first arm member aperture and pivotally attached to said center support about said second longitudinal axis;
- a second arm member having a second arm member aperture and pivotally attached to said center support about said second longitudinal axis;
- a latching mechanism having an alignment member having an aperture in general alignment with said aperture of each of said first and second arm members and an alignment pin, and said alignment member being mounted to said center support;
- a latching member having a latching pin in general alignment with said aperture of each of said alignment member and each of said first and second arm members, and said latching member in slidable engagement with said alignment pin;
- and
- an actuation member mounted between said alignment member and latching member, actuation of said actuation member in a first direction passes said latching pin through said aperture of said alignment member and each of said first and second arm members, movement of said actuation member in a second direction disengages said latching pin from said alignment member and each of said first and second arm members,
- wherein said alignment member has a pair of plate members being spaced apart and said first and second arm members each having a latching ear, and said latching ear being positioned between said pair of plates during actuation of said actuation member in said first direction.
