Abstract
An agricultural tillage system including a carriage frame assembly, a plurality of tillage elements coupled to the carriage frame assembly, an actuator and a residue reactive system. The actuator is moveably coupled to the tillage elements, and is directly in control of a soil contact depth of the tillage elements. The residue reactive system is in controlling communication with the at least one actuator. The residue reactive system reduces the soil contact depth of the tillage elements when the residue mass on the soil is reduced and/or the slope of the soil is above a predetermined value.
Claims10
An agricultural tillage system, comprising:
- a carriage frame assembly;
- a plurality of tillage elements coupled to the carriage frame assembly;
- at least one actuator moveably coupled to the tillage elements, the actuator being directly in control of a soil contact depth of the tillage elements;
- a residue reactive system in controlling communication with the at least one actuator, the residue reactive system reduces the soil contact depth of the tillage elements when at least one of a residue mass on the soil is below a first predetermined value and a slope of the soil is above a second predetermined value;
- and
- a residue mass determiner that provides the residue reactive system with residue mass values for locations in a field of operation, the residue mass determiner includes a use of a yield map of the field, the residue mass on the soil being estimated from yield data of a previously harvested crop of the field at a geographic position of the agricultural tillage system.
A depth control system for an agricultural tillage system having a carriage frame assembly and a plurality of tillage elements coupled to the carriage frame assembly, the depth control system comprising:
- at least one actuator moveably coupled to the tillage elements, the actuator being directly in control of a soil contact depth of the tillage elements;
- a residue reactive system in controlling communication with the at least one actuator, the residue reactive system reduces the soil contact depth of the tillage elements when a residue mass on the soil is below a predetermined value;
- and
- a residue mass determiner that provides the residue reactive system with residue mass values for locations in a field of operation, the residue mass determiner includes a use of a yield map of the field, the residue mass on the soil being estimated from yield data of a previously harvested crop of the field at a geographic position of the agricultural tillage system.
