The instant invention is a machine / implement used for soil preparation and seeding intended for farming and gardening that mounts on a standard three point hitch and is powered by the tractor's power-take-off (PTO). The implement integrates the processes of ground breaking, tilling, fertilizing and planting in one adjustable unit. The adjustments include the spacing and depth of the ground cutting and tilling blades and the openings of the fertilizing ports to prepare the ground for planting in defined strips leaving the majority of ground only lightly disturbed. To achieve these goals, the apparatus is comprised of two frames, a lower one that contains the blades that break the ground crust ahead of the tiller tines that grind the soil into finer particles for planting. The lower frame also has a rear flap that levels and marks the tilled soil and also supports seed boxes with a mechanism that allows the seeder / seeders to set seed at a constant depth on uneven ground. The spacing of the seed boxes are determined by mounting holes in the apron. The upper detachable frame contains a bin that filters, holds and dispenses the fertilizer by mixing it down through adjustable ports directly above and forward of the tiller blades to be mixed with the earth during tilling thus making it possible to break the ground, till, fertilize and seed in a single pass.

A hydraulic lock of a tiller-based watercraft steering system is responsive to tiller release to lock a watercraft's steered element in the last commanded position upon tiller release. The hydraulic lock can be controlled through an actuator assembly that is provided between a tiller arm and the watercraft's steered element. One or more cables connect the actuator assembly to other components of the hydraulic lock. A thermal compensator regulates pressure within the hydraulic lock by accommodating changes in temperature related characteristics of the fluid within the hydraulic lock Increases in fluid pressure due to thermal expansion can be mitigated within the thermal compensator by automatically or manually directing a volume of fluid from the hydraulic lock, through a compensating valve assembly, and into a reservoir. Decreases in fluid pressure can be mitigated by directing fluid from the reservoir back into the hydraulic lock.

A directional nozzle for the jet output that is attached to a control cable system. This cable turns the directional nozzle, which causes the trust of the jet output to turn the boat. Thus, the boat can be steered without having to turn the entire motor. Two different mechanisms are disclosed that enable the steering. The first is a tiller system that operates much like the traditional tiller on an outboard motor. However, unlike those tillers, this tiller operates the directional nozzle and does not turn the entire motor. The second mechanism is a bicycle handlebar system that is placed forward of the motor, much like a traditional wheel. The handlebar system, when combined with the directional nozzle system, produces faster steering response without the effort required to turn the wheel to make large sweeping turns.

A freestanding self-propelled device for moving objects. The device includes a chassis having lower frame portions and upright frame portions. A single motor-driven drive wheel is centrally located between the lateral ends of the chassis and coupled to the chassis so as to be pivotable about a substantially vertical axis. The drive wheel is located between sets of support wheels coupled to the lower frame portion of the chassis. In combination, the drive wheel and the support wheels result in the device being freestanding. The drive wheel projects below the sets of support wheels so that the device is supported by the drive wheel and by only one of each set of support wheels at any given time, thereby establishing a three-point contact with the surface supporting the device. A tiller equipped with controls is pivotably coupled to the drive wheel for pivoting the drive wheel about its vertical axis.

A steering mechanism includes a handle with a tiller arm coupled to the handle via a flexible joint allowing relative movement of the handle about the tiller arm. A handle centering mechanism forming part of the steering mechanism includes a first end fixedly secured to the handle and a second end extending into a channel of the tiller arm. The second end compresses bumpers disposed on opposing sides of the second end. The bumpers urge the handle toward a neutral position wherein when a force is applied to move the handle away from a home position relative to the tiller arm, one of the compressed bumpers of the pair of compressed bumpers is further compressed. When the force is removed, the handle is returned to the home position by action of the pair of compressed bumpers. Preferably, the steering mechanism includes a torque sensing arrangement having a sensor and a magnet. The sensor produces a signal based on movement of the handle relative to the tiller arm by sensing changes in the magnet field of the magnet proportional to the torque exerted on the handle regardless of the angle of the tiller arm.
