Adjustable harvester systems and methods for use in liquid environments

A harvester system for removing solid material from a liquid environment, the harvester system comprising:

• a cutter assembly including a housing and one or more blades within the housing, the housing including a front opening configured to receive the solid material from the liquid environment into the housing to be cut by the one or more blades;
• a vehicle supporting the cutter assembly in the liquid environment such that the cutter assembly moves between (i) a first configuration in which the cutter assembly is located at a first vertical position above a surface of the liquid environment, and (ii) a second configuration in which the cutter assembly is lowered to a second vertical position so that the front opening of the housing is at least partially submerged into the liquid environment;
• and
• a pump hose operably connecting the cutter assembly to a pump such that the pump causes the solid material cut by the one or more blades to be pumped out of the housing and away from the vehicle.

A method of removing solid material from a liquid environment, the method comprising:

• submerging a cutter assembly including a housing and one or more blades at least partially into the liquid environment in an area of the liquid environment containing solid material;
• moving the cutter assembly through the liquid environment while operating the one or more blades so that the solid material flows into the housing and is cut by the one or more blades;
• and
• pumping the solid material cut by the cutter out of and away from the cutter assembly via a hose operatively attached to the housing.
