Claims14
An agricultural implement comprising:
- (a) a center section comprising (i) a center bar coupled to a first inner wing section and a second inner wing section and (ii) a first and second center wheel assembly;
- (b) a first and second outer wing section, with each outer wing section comprising an outer wing wheel assembly and an outer wing fold actuator;
- and
- (c) a control system comprising:
- (i) a fluid control system comprising a pressurized oil port and tank port that are in fluid communication with a control valve;
- wherein the control valve is in fluid communication with the first and second outer wing fold actuator and is configured to fold the first and second outer wings when the control valve is opened;
- and
- (ii) a monitor in electrical communication with the control valve;
- wherein the monitor is configured to adjust the pressure in the control valve associated with the first and second outer wing fold actuators;
- and
- wherein the monitor is configured to receive a signal from a first and second outer wing wheel load sensor, each of which is associated with the first outer wing wheel assembly and the second outer wing wheel assembly, respectively;
- wherein the first outer wing fold actuator is pivotally mounted to a first end of the first inner wing section and a second end of the first outer wing section, and the second outer wing fold actuator is pivotally mounted to a first end of the second inner wing section and a second end of the second outer wing section.
