A method for automatically operating a dredge having a swingable and elevatable ladder with a cutter head having a speed comprising the steps of:
- (a) providing an automatic swing sequence for the ladder;
- (b) providing a rate control for the cutter head;
- and
- (c) providing an automatic raise control sequence for the ladder.
A method for automatically operating a dredge having a swingable and elevatable ladder with a cutting head having a speed comprising the steps of:
- (a) providing an automatic swing sequence for the ladder, wherein said automatic swing sequence includes an automatic swing rate control and an automatic swing rate speed decrease control;
- (b) providing a cutter head rate control wherein said cutter head rate control includes an automatic head speed decrease control sequence which includes the further step of measuring the pressure at the cutter head;
- (c) providing an automatic ladder raise control sequence;
- and
- (d) providing a material discharge line including the step of measuring pressure at said discharge line.
