A hydraulic control system is disclosed for an excavation machine including a tool linkage system. The hydraulic control system may have a first actuator configured to move a first link of the tool linkage system in response to input from an operator of the excavation machine, and a pressure sensor configured to generate a signal indicative of a pressure of the first actuator. The hydraulic control system may also have a second actuator configured to move a second link of the tool linkage system in response to input from the operator. In addition, the hydraulic control system may have a controller in communication with the pressure sensor, the first actuator, and the second actuator. The controller may be configured to automatically affect operation of the first actuator based on the pressure signal at times when movement of the second actuator is being requested by the operator and movement of the first actuator is being requested by the operator at a level less than a threshold.

Boom assist management feature

A method of operating a machine at a worksite includes determining data associated with at least one of a machine operation at the worksite and a worksite condition, and determining, based on the data, that one of machine propulsion and machine retarding will be required for greater than a corresponding threshold. The method also includes determining, in response to determining that machine propulsion will be required, a desired propulsion gear, and recommending the propulsion gear to an operator of the machine. The method further includes determining, in response to determining that machine retarding will be required, a desired retarding gear, and recommending the retarding gear to the operator. In such a method, the retarding gear is determined based on a maximum temperature associated with the machine.

Worksite management system with gear recommendation

A worksite management system for use with a mobile machine is disclosed. The worksite management system may have a control module located onboard the mobile machine and configured to store a least one operational relationship, and an offboard controller located at a worksite of the mobile machine in communication with the control module. The offboard controller may be configured to generate an analysis of machine performance at the worksite. The offboard controller may be further configured to cause remote reconfiguration of the at least one operational relationship based on the analysis to positively affect performance of the mobile machine.

Worksite management system implementing remote machine reconfiguration

A worksite management system for use with a mobile machine is disclosed. The worksite management system may have a control module located onboard the mobile machine and configured to control operations of the mobile machine, and a controller in communication with the control module. The controller may be configured to anticipate a non-failure machine performance irregularity, and determine an adjustment to an operation of the mobile machine that positively affects the machine performance irregularity. The controller may also be configured to cause implementation of the adjustment before the machine performance irregularity occurs.
