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.

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 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.
