摘要： A light weight, portable aquatic vegetation cutter having a handle disposed at one end of a mounting rod, a motor at the other end of the mounting rod, the motor being disposed essentially centrally between two reciprocating type cutting blade assemblies ranging in opposite directions from the motor, the handle being adapted substantially to indicate the horizontal disposition of the cutting blade assemblies and permitting their realignment relative to the direction in which aquatic vegetation cutting takes place, the position of the motor with the cutting blade assemblies, being adjustable in two directions relative to the vertical, that are perpendicular to each other, a boat mounting attachable from the mounting rod, providing three additional directions of yieldable freedom of motion, audible and visual means for signaling a problem in cutting ability of the aquatic vegetation cutter, a switch enabling momentary reversal of the polarity of DC current to the motor, for freeing matter caught between the toothed reciprocating cutting blade and toothed stationary cutting blade of a cutting blade assembly, and a switch for preventing turning the motor on when it is not immersed into a sufficient depth of water.

摘要： An underwater weed cutter comprises a generally W-shaped object which is cut out of a plate or sheet of metal and is configured similar to two scythes whose opposite ends are joined together to form a unitary object which has a line attached to it to provide for pulling it along the bottom of a body of water to shear off and collect underwater weeds. The weed cutters are configured such that the outside or convex boundary of one of them is complementary in shape to the inside or concave boundary of another of them so that there is no metal waste developed between the cutters when they are being cut from the plate.

摘要： A plastic tube serving as a rake head has teeth disposed along its undersurface and a pair of spaced-apart aluminum tubes. The plastic tube is injected with buoyant filler material to make the rake floatable. A rope is secured to the outer end of one aluminum tube, extends to form a loop, and is secured at its other end to the outer and second of the aluminum tube. An inner handle bar is slidably disposed between the looped rope outward of the aluminum tubes, and an outer handle is disposed at the end of the loop, allowing the user to retrieve weeds from water by first using the outer handle bar, and to remove the weeds by using the inner handle bar.

摘要： An articulated-boom hoist is attachable to a motorized vehicle and structured to transfer an aquatic rake and rake float between a carrier and a body of water to be cleaned of aquatic plants. The aquatic rake is placed on the rake float. The rake float on the body of water is propelled to a select distance from the motorized vehicle. The aquatic rake is then removed from the rake float, dropped into the body of water and pulled towards the motorized vehicle with a winch and winch line attached to the motorized vehicle which is anchored appropriately in resistance to the winching action. Aquatic plants are uprooted from a bed of the body of water thereby. The articulated-boom hoist is then employed to lift the aquatic rake with aquatic plants gathered thereon from the body of water and position it above a transport vehicle or other dump site. The aquatic rake is tilted appropriately to cause aquatic plants to drop from it. Then the aquatic rake is repositioned back on the rake float to repeat the process as desired. The articulated-boom hoist can be either vertically swivelable or both vertically and horizontally swivelable, depending on use-condition tradeoff factors. If the articulated-boom hoist is horizontally swivelable, the motorized vehicle to which it is attachable need not be moved to dump aquatic plants from the aquatic rake. A float boom is optional for positioning the rake float with the aquatic rake thereon for drag-line cycles of operation.

摘要翻译： 铰接式起重机提升机可附接到机动车辆上，并构造成将水耙和耙浮子转移到载体和水体之间，以清理水生植物。 水耙放在耙浮子上。 水体上的耙子浮动被推进到与机动车辆的选择距离。 然后将水耙从耙浮体中取出，落入水体，并用连接在机动车辆上的绞车和绞车线向机动车辆拉出，该车辆适当地锚固在绞车动作上。 水生植物从水体的床上被连根拔起。 然后使用铰接式起重机将水耙与从水体聚集的水生植物提升，并将其放置在运输车辆或其他倾倒场所上方。 水耙被适当倾斜，导致水生植物从其中掉落。 然后将水耙重新定位在耙浮子上，以根据需要重复该过程。 铰接式起重机可以垂直旋转，也可以垂直和水平可旋转，具体取决于使用条件的折衷因素。 如果铰接式起重机葫芦水平可旋转，则可附接的机动车辆不需要移动，从水耙倾倒水生植物。 浮动吊杆是可选的，用于将耙浮子与水耙定位在其上用于拖曳操作循环。

摘要： A semi-submersible flotsam harvesting vessel is provided which has gunwale floats and a hinged bow section and which cooperates with a floating receptacle to unload the harvest. The method of harvesting includes swamping the vessel by lifting the bow section to float the flotsam into the hold, closing the bow and energizing the motor to put the hull on plane to drain the water from the flotsam for high speed travel to the floating receptacle where the vessel is again swamped to float the flotsam into the container as the vessel withdraws with bow open.

摘要： A weeder capable of removing large and small sized weeds from inland waterways is arranged for towing off the back of a row boat as well as for manual operation. The weeder is in the form of a rectangular expanded metal section pivotally attached to towing ropes at opposite ends. The sides of the expanded metal section are sheared to form a V-groove or slot configuration for trapping the weeds along the bed of the waterway where the roots meet the weed stalk. The expanded metal perforations allow the weeds to be carried to the surface of the water while allowing the water to escape between the perforations. One side of the expanded metal section is provided with an additional expanded metal section to form V-grooves of smaller width to remove the smaller weeds.

摘要： A harvester for plants and weeds, particularly aquatic plants, pulls the plants by winding them onto a rotating, endless cable. Tension in the cable is controlled, and an operative portion of the cable is positionable for varying its height and angle to the horizontal. The harvester is mountable on a boat having an adjustable freeboard and multiple, individually driven, retractable paddle wheels provide maximum maneuverability during use and compactness during transport.

摘要： Aquatic plants and their entangled roots can be removed from a lake or other body of water by pulling a lake rake out onto the lake, then pulling the lake rake, with a load of plants and their roots, back in to a central collection site on shore. Multi-purpose teeth of this rake are shaped and positioned to glide across the surface of a lake on the outbound trip, to dig below rooted plants on the inbound trip, and to pass over small crevices or uneven joints on a ramp, truck or trailer at the collection site. Embodiments of the invention may be constructed in a variety of sizes from standard size materials that are commercially available, such as aluminum, steel or plastics.

摘要： A cutting tool for use in conjunction with the propeller assembly of a boat to prevent underwater foliage from fouling the drive mechanism of the boat. The shank end of the tool is secured to the motor housing and supports the cutting blade end thereof in close proximity with the propeller hub. As the hub rotates, underwater foliage encountered by the propeller assembly is swept into contact with the cutting edges of the blade whereupon the foliage is cut and the cutting thrown away from the motor.
