How to wire in a combine side knife

More and more modern combines come with built-in side-knives, meaning there are increasing numbers of bolt-on units lying in the corner of farm workshops and occasionally popping up on eBay.

That means it’s now more affordable than ever to have the ultimate luxury that any self-respecting combine driver dreams of – side-knives either side. With one on the left and another on the right, it’s no longer compulsory to cut in lands and striking out through the middle of a crop is pure pleasure.

But getting them installed correctly is pretty important, particularly if the electrical jiggery-pokery of your prized new find looks a little dubious. We got hold of wiring kits from spare-parts supplier Spaldings and the importer of Matrot side-knives, Garford, and set about fitting them.
