MacDon Industries, LTD. is an OEM (original equipment manufacturer) headquartered out of Winnipeg, Manitoba. They have been world leaders in the technology, innovation and manufacturing of high quality, high performance harvesting equipment for over 65 years, beginning back in 1949 as Killbery. MacDon has a global presence of over 40 countries, on 6 continents. These products range from hay equipment such as rotary and auger header pull-type windrowers, to pick-up and draper headers for combine harvesters. Additionally, they produce a line of self-propelled windrowers designed to operate rotary, auger and draper headers for a variety of uses to producers.

A used self-propelled windrower can cost roughly $100,000 from a reputable dealer and a new windrower can cost upwards of $150,000. Purchasing a tractor after the purchase of an expensive windrower can be a difficult proposition. For many small farming operations it is not economically sound for them to make this kind of investment. A farming operation that requires the use of a windrower also requires a tractor to power implements such as small, square and round balers as well as grain augers and other low horse power non-tillage implements. MacDon’s patented Dual Direction® windrowers (U.S. Patent 7159687B2), provides the opportunity for a unique solution to this issue. By mounting a drawbar and hydraulically driven PTO (power take-off) to the header connections, the MacDon M155 windrower can replace many tractor functions.



Problem Statement

The goal of this project was to create an economical and reliable apparatus to attach to a MacDon M155 windrower, using the attachment points that come factory installed on the windrower.

Scope of Work

The scope of the project covers the design, prototyping, and testing of a hitch assembly to attach to an M155 windrower. The hitch assembly was designed with a multi-position drawbar, hydraulically powered PTO, and a bank of hydraulic outlets. The overall cost of components was modeled within MacDon’s criteria to make the system more desirable to consumers. Missing Link Engineering explored the feasibility and practicality of the system having a self-contained transport system as opposed to it being free standing for hookup. The deliverables of the project include an apparatus capable of trailering and powering small non-tillage implements with either a transport system or an apparatus to make the apparatus self-supporting when not mounted to the windrower.
