    Ground-Driven PTO Forecart converted from antique tractor

    Ground-Driven PTO Forecart converted from antique tractor

    This ground-driven PTO forecart is made out of a CASE VC tractor. We split the engine off of the rear end, and built the rear end up into a cart, adding a deck, tongues, a seat, and a railing. Generally, a forecart is used in between a team of draft horses and a piece of farm equipment and includes a place for the teamster to stand or sit while operating the machinery. For us at the Northland Sheep Dairy that means a 14 ft rotary tedder (tested and functional) but it could be used for many different PTO-driven pieces of equipment--perhaps even combines and balers. This project was undertaken at the Northland Sheep Dairy by Donn Hewes.

    Outside Air Exchange Control

    This tool demonstrates the use of two thermostats to provide a control system for an air exchange fan that draws cold outside air in to cool a storage room for winter crops. The control essentially provides a differential temperature control which may also be applicable to other processes (curing, solar hot water, etc.)

    A "sweat box" style germination chamber built using readily available parts and a broken chest freezer.

    Self Contained Mobile Biodiesel Processing Trailer

    Self Contained Mobile Biodiesel Processing Trailer

    The farm based self contained mobile biodiesel plant constructed by GreenStart is based on a common aluminum beverage trailer platform. The heat and power is provided by a 3 phase diesel generator coupled with a 10hp air compressor. Each functional component is designed to fit the standard beverage skid of 36" square which enables swapping of components. The shutter sides provide secure weatherproof environment for storage and transport. The low deck height also facilitates operation and maintenance from the ground level.
