An amphibious vehicle for operation in a liquid manure lagoon has a first liquid manure mover (e.g., a propeller or a nozzle) that is vertically adjustable through a closed-loop linkage assembly to change the vertical position of the first liquid manure mover with respect to the surface of the liquid manure lagoon. The vehicle has a second liquid manure mover (e.g., a propeller or a nozzle) that is angularly adjustable to adjust the orientation of the second liquid manure mover with respect to the surface of the liquid manure lagoon.

Aspects of the present disclosure generally pertain to an amphibious vehicle (or amphibian) that is viable on land as well as on water. Aspects of the present disclosure more specifically are directed toward an amphibious vehicle that employs hydrofoils and other features, for example, for efficient cruising when in water. The amphibious vehicle may be embodied as a personal amphibious vehicle.

A transmission for a vehicle, particularly a skid-steered vehicle, that employs motive power from a prime mover delivered through an input shaft to drive left and right drive shafts at a nominal speed and input power from an electric motor to vary the speed of the left and right drive shafts according to steering commands from a steering control structure. The speed of the left and right drive shafts is directly related to a speed of the input shaft and the nominal speed of the left or right drive shaft is varied upwardly or downwardly by a ratio of the speed of the steering shaft via a speed varying structure. The speed of the left and right drive shafts is simultaneously varied in opposite directions (i.e. upwardly and downwardly) relative to the nominal speed by an equal number of rotations.

Techniques are directed to a modular vehicle belly armor kit, as well as systems and methods which utilize such a kit. The kit includes a bottom plate, a top plate, and a plurality of wall sections connecting with the bottom plate and the top plate to form an armor structure that protects a belly portion of the vehicle. After the modular vehicle belly armor kit is positioned underneath a vehicle, the bottom plate may be placed in contact with the vehicle. After the bottom plate is placed in contact with the vehicle, the bottom plate may be fastened to vehicle.

A combination of a marsh buggy is coupled with a modified skid steer. The skid steer has a frame, and hydraulic lines for attaching to hydraulic driven motors for driving a track or wheeled drive system. The skid steer further having an engine and a hydraulic system, including a pump and hydraulic tank, and valves; an operator's cab positioned on the frame, said operator's cab further comprising a set of hydraulic controls connectable to the hydraulic system for controlling the drive system and a hydraulically driven lift system, including two booms, each boom comprising a first arm and a second arm, the first arm being pivotably mounted to the frame, the second arm being telescopically coupled to the first arm by a hydraulic cylinder controllable from the operator's cab. The marsh buggy includes a first and a second floatable pontoons, the two pontoons coupled together in a parallel but offset relationship. Each pontoon has an endless track including a chain and treads coupled around the periphery of each respective pontoon, and a series of sprockets coupled to the chain on each pontoon; each sprocket connected to a hydraulic motor. The marsh buggy further has hydraulic motors and drive sprockets coupled to the hydraulic system for driving the endless track. The skid steer is mounted on the marsh buggy, between the two pontoons, and the hydraulic motors of the marsh buggy are operationally coupled to said hydraulic system of said skid steer so that said hydraulic controls in said cab are operationally connected to said hydraulic motors to control the drive system on the marsh buggy.

An Amphibious Vehicle (AV) is capable of planing with less power than prior similar size amphibious vehicles and using mostly off-the-shelf part. The AV uses an outdrive and propellor instead of a pump, and also include leading rear wheel well flaps which are spring biased forward against the hull bottom for on-road use, and pivot back to fill a gap between the hull and rear tire, reducing drag during in-water use. The combination of the propellor and wheel well flap allows planing with less horse power. An engine faces to the rear and either reversing differentials to reversing carrier and hubs provide correct wheel rotation. A reversing gear box attaches to an engine front and reverses rotation providing correct rotation for an outdrive and propellor.

Various embodiments of an amphibious submersible vehicle for use in non-destructive testing of pipe interiors and walls are disclosed herein. In one aspect, the vehicle is operable for amphibious submersible operation such that pipes of various diameters can be inspected under full, partially full, and dry conditions. In another aspect, the vehicle is equipped with a plurality of propellers for travel when fully or partially submerged in water and a plurality of wheels for traveling when in contact with a pipe wall or for traveling over debris. In some embodiments, the vehicle is equipped with a plurality of sensors configured for imaging and navigation which enable the vehicle for pipe inspection and identification of problem areas.

An amphibious vehicle has a floatable vehicle body; ground engaging propulsion structure having a plurality of ground engaging elements powered by a hydraulic motor; a fluid pump for pumping liquid manure; a power source connected to a hydraulic pump and configured to provide power to both the ground engaging propulsion structure and the fluid pump; and, remote control structure for controlling the ground engaging propulsion structure and a flow of fluid from the fluid pump. The speed and/or direction of the vehicle is remotely controllable by an operator remote from the vehicle when the vehicle is ground engaging and when the vehicle is floating.
