Abstract
This document relates to an agricultural implement with hydraulic functions and a method of controlling an agricultural implement comprising receiving a speed signal which represents the advancing speed of the agricultural implement, receiving a control signal from a first user interface, allowing, if the speed fulfils a predetermined criterion, the activation of a first actuator function and of a second actuator function based on a control signal, and, if the speed does not fulfil the criterion, restricting the possibility of activating the first actuator function based on a control signal.

Method of controlling an agricultural implement comprising:
- receiving a speed signal which represents an advancing speed of the agricultural implement,
- receiving a control signal from a first user interface,
- allowing, if the speed signal fulfils a predetermined criterion, the activation of a first actuator function and of a second actuator function based on the control signal,
- restricting, if the speed signal does not fulfil the criterion, the possibility of activating the first actuator function based on the control signal,
- supplying the first actuator function via a main regulator, wherein said activation is permitted in that the main regulator is opened,
- allowing, if the speed signal does not fulfill the criterion, activation of the first actuator function based on the control signal only if there is an input from a second user interface, whereby the main regulator is by-passed by way of the second user interface.
Method of controlling an agricultural implement comprising:
- receiving a control signal from a first user interface,
- determining a position of the first user interface,
- allowing, if the position is an safe area, the activation of a first actuator and of a second actuator function based on the control signal,
- supplying the first actuator function via a main regulator, wherein said activation is permitted in that the main regulator is opened,
- restricting, if the position is not in a safe area, the possibility of activating the first actuator function based on the control signal, and
- allowing, if the position is not in the safe area, the activation of the first actuator function based on the control signal only if there is an input from another user interface, whereby the main regulator is by-passed by way of the second user interface.
Agricultural implement comprising:
- a first actuator function,
- a second actuator function,
- a first user interface,
- a second user interface,
- a first speed sensor configured to detect an advancing speed of the agricultural implement, and
- a control unit which is configured to receive a speed signal from the first speed sensor and which is configured to control the first and second actuator functions based on a control signal from the user interface,
- a main regulator via which one of the first and the second actuator functions is supplied with power, which can be by-passed with the aid of the second user interface,
- wherein the control unit is configured:
- to allow, if the speed signal fulfils a predetermined criterion, the activation of a first actuator function and of a second actuator function based on the control signal, and
- to restrict, if the speed signal does not fulfil the criterion, the possibility of activating the first actuator function based on the control signal by permitting activation of the first actuator function based on the control signal only if an input from the second user interface is provided so that the main regulator is by-passed.
Agricultural implement comprising:
- a first actuator function,
- a second actuator function,
- a first user interface,
- a control unit which is configured to receive an activation signal from the user interface and which is configured to control the first and second actuator functions,
- a position sensor for determining the position of the first user interface,
- a main regulator via which one of the first and the second actuator functions is supplied with power, which can be by-passed with the aid of the second user interface,
- wherein the control unit is configured:
- to allow, if the position is not in a safe area, the activation of a first actuator function and of a second actuator function based on the control signal, and
- to restrict, if the position is not in the safe area, the possibility of activating the first actuator function based on the control signal,
- wherein restricting the possibility of activating the first actuator function is achieved by permitting activation of the first actuator function based on the control signal only if an input from the second user interface is provided so that the main regulator is by-passed.
