This year’s Farm Inventions competition was packed full of bright ideas conceived in the farm workshop.

Entries flooded in from all corners of the country and included everything from simple fencing tools and sheep handling kit to hefty cultivators and complex drills.

As always, the format of the competitions remains the same, with entries falling into three categories: simple, intermediate and complex.

Simple machines are those that took a day or so to knock together. Intermediate ones involve a bit more time and thought. The complex category covers those impressive inventions that have taken days, weeks or even years to design and build.

See the category winners below and for more on the winners, runners up and our best picks of the competition see the full feature: The best farm machinery inventions of 2015.
