Research

• Spader Function - is to till the soil in preparation of the next planting process, seeding.

• Tilling - consists of agitating the soil through means such as digging, stirring, and overturning. Tilling aids in soil aeration, organic matter dispersal, and weed removal.

• Soil Aeration - refers to the spacing out of soil as to make the soil less compacted. Soil aeration improves drainage and reduces puddle formation.

• Organic Matter Dispersal - refers to the spreading of plant material throughout the soil as to improve the uniformity of nutrient concentration within a given volume of soil.

Conceptual Notes

• Front - includes the towing mechanism that allows the spader to be pulled by a tractor.

• Middle - includes the frame, covers, and rotors of the spader.

• Top - includes the hydraulic circuit of the spader.

Development

Overview

• Spading System - consists of rotors, spades, and tines that make actual contact with the soil.

• Hydraulic System - consists of the hydraulic components that power the rotation of the rotors in the spading system.

• Structural System - consists of the chassis and the cover used to strengthen and protect the spader, respectively; the cover also contains the movement of overturned soil.
