Janke Bros Engineering (Australia) is a progressive manufacturing company
specialising in minimum tillage machinery for the agricultural market. They specialise
in the customisation of machines to suit the customers farming practices, this enables
the grower to purchase a machine that will do several separate operations with minimal
Currently they manufacture two main lines of direct drill planters, a fixed tyne unit and
a parallelogram unit. The parallelogram unit gains the majority of the attention from
customers. The features that appeal to the customers are the ability for the parallelogram
to follow the contours of the ground and the leading coulter disc that is able to cut the
trash ahead of the tyne.
In the current market place there is a trend towards minimum tillage farming, which
incorporates the use of double and single disc openers. However disc openers are not
able to work in dry conditions, they are not able to reach through the dry crust to the
moisture below where a direct drill tyne is able to. To obtain the best of both worlds
Janke intend to redesign the current F500P parallelogram unit to have interchangeability.
This would enable the customer to remove the leading coulter and tyne,
replacing it with either a single or double disc opener, depending on the planting
The design process involved: - Design the double/Single disc unit, using as many of Jankes current range of
products as possible, and the new attachment system. - The newly designed disc opener and attachment is to be tested on a finite
element analysis (FEA) package. Allowing a better visualisation of the
attachment method and eliminate the need to redesign the attachment system
after testing. - A prototype can be constructed and tested in the field, enabling Janke to produce
the new design for the next winter crop planting (April-May 2005).
