Abstract

A tillage implement comprising a main frame, a front group of coulter blades carried by the main frame and extending generally laterally, and a rear group of coulter blades carried by the main frame and extending generally laterally. The tillage implement additionally comprises a set of wheels configured to support the main frame and positioned generally between the front and rear groups of coulter blades. The tillage implement additionally comprises a group of harrow assemblies carried by the main frame and positioned rearward of the rear group of coulter blades. The tillage implement additionally comprises a front group of finishing reels carried by the main frame, extending generally laterally, and positioned rearward of the group of harrow assemblies. Furthermore, the tillage implement comprises a rear group of finishing reels carried by the main frame, extending generally laterally, and positioned rearward of the front group of finishing reels.

Dependent claims

A tillage implement comprising:

a main frame;
a front group of coulter blades carried by said main frame and extending generally laterally across said tillage implement;
a rear group of coulter blades carried by said main frame and extending generally laterally;
a set of wheels configured to support said main frame on a ground surface, wherein said set of wheels is positioned generally between said front and rear groups of coulter blades, wherein said set of wheels is configured to adjust a height of said main frame with respect to the ground surface such that said tillage implement is shiftable between an operating configuration and a transport configuration, wherein said main frame is positioned closer to a ground surface in the operating configuration than in the transport configuration,
wherein when said tillage implement is in either the operating configuration or the transport configuration said set of wheels is positioned closer to said rear group of coulter blades than said front group of coulter blades,
wherein when said tillage implement is in the operating configuration a distance D1 is presented between said set of wheels and said front group of coulter blades, wherein a distance D2 is presented between said set of wheels and said front group of coulter blades, and wherein a ratio of D2 to D1 is in the range of 1:1.2 to 1:1.7;
a group of harrow assemblies carried by said main frame and positioned rearward of said rear group of coulter blades;
a front group of finishing reels carried by said main frame, extending generally laterally, and positioned rearward of said group of harrow assemblies;
and
a rear group of finishing reels carried by said main frame, extending generally laterally, and positioned rearward of said front group of finishing reels.

A tillage implement comprising:

a main frame;
a first gang of coulter blades carried by said main frame, wherein said first gang of coulter blades is configured to rotate between a minimum gang angle and a maximum gang angle, wherein said minimum gang angle is less than 2 degrees and said maximum gang angle is at least 7 degrees;
a second gang of coulter blades carried by said main frame configured to rotate between a minimum gang angle and a maximum gang angle, with the minimum gang angle being less than 2 degrees and the maximum gang angle being at least 5 degrees;
a set of wheels configured to support said main frame on a ground surface, wherein said set of wheels is positioned rearward of said first gang of coulter blades and forward of said second gang of coulter blades, wherein said set of wheels is configured to adjust a height of said main frame with respect to the ground surface such that said tillage implement is shiftable between an operating configuration and a transport configuration, wherein said main frame is positioned closer to a ground surface in the operating configuration than in the transport configuration,
wherein when said tillage implement is in the operating configuration and the transport configuration said set of wheels is positioned closer to said second gang of coulter blades than said first gang of coulter blades,
wherein when said tillage implement is in the operating configuration a distance D1 is presented between said set of wheels and said first gang of coulter blades, wherein a distance D2 is presented between said set of wheels and said second gang of coulter blades, and wherein a ratio of D2 to D1 is in the range of 1:1.2 to 1:1.7;
a set of rolling harrow assemblies carried by said main frame and positioned rearward of said second gang of coulter blades;
and
a plurality of rear finishing reels carried by said main frame and positioned rearward of said set of rolling harrow assemblies.
