Abstract
A work machine with a first tire having a first tire pressure sensor configured to identify a first tire pressure, a load sensor coupled to the work machine and configured to measure an actual load weight, and a controller in communication with the first tire pressure sensor and the load sensor. Wherein, the controller identifies a tire pressure value with the first tire pressure sensor and the controller determines a current load weight threshold from a plurality of load weight thresholds with the tire pressure value.
Claims20
An implement, comprising:
- at least one frame section configured to be coupled to a work machine through a hitch assembly;
- a ground engaging mechanism;
- at least one work tool defined along a tool axis and pivotally coupled to the at least one frame section and configured to pivot relative to a transvers axis defined through the at least one frame section to alter the tool axis relative to the transverse axis, wherein the transverse axis is defined transversely relative to a longitudinal frame axis;
- a load identifying sensor that identifies a load value acting on the ground engaging mechanism;
- and
- a controller in communication with the load identifying sensor;
- a work tool actuator coupled to the at least one frame section and configured to selectively pivot the at least one work tool to alter the tool axis relative to the transverse axis to change a tool angle defined between the tool axis and the transverse axis to an orientation wherein the tool axis is not parallel to the transverse axis;
- wherein, when the load value is not within a load threshold, the controller initiates a response that comprises altering the tool angle of the at least one work tool in a fore direction or an aft direction relative to the transverse axis of the at least one frame section with the work tool actuator.
A system for monitoring engagement of an implement with an underlying surface, comprising:
- a positioning system configured to reposition a second frame segment relative to a first frame segment;
- a controller configured to communicate with a load sensor and the positioning system;
- a user interface configured to communicate a desired tool depth of a work tool to the controller;
- and
- a ground working mechanism having a tool angle defined between a tool axis through the ground working mechanism and a transvers axis defined transversely relative to a longitudinal frame axis;
- wherein, the controller initiates a response when a load value of the load sensor is not within a load threshold as the work tool transitions to the desired tool depth;
- wherein the response initiated by the controller includes changing the tool angle of the ground working mechanism with a work tool actuator in a fore direction or an aft direction relative to the transverse axis to an orientation wherein the tool axis is not parallel to the transverse axis.
A method of controlling the height of an implement over an underlying surface, comprising:
- providing the implement having a controller configured to:
- store, in the controller, a load value threshold;
- monitor, with the controller using a load identifying sensor, a load acting on a ground engaging mechanism;
- and
- initiate a response, with the controller, when the load acting on the ground engaging mechanism is not within the load value threshold, the response comprising changing a tool angle defined between a tool axis through a ground working mechanism and a transvers axis defined transversely relative to a longitudinal frame axis with a work tool actuator in a fore direction or an aft direction relative to the transverse axis to an orientation wherein the tool axis is not parallel to the transverse axis.
