An irrigation gantry
What do you do with a retired linear move irrigator? If you're Hugh Ritchie, you donate it to the LandWISE MicroFarm.
The Ritchies replaced their original Drumpeel Farm linear after about 16 years and 16,000 hours of on-site use. They donated its parts to make a single span machine for the MicroFarm. And last Saturday, Hugh arrived with a truck and trailer carrying the cart and parts and a Manitou to put it up with. We have gone for a single span machine, with the cart moving up and down the MicroFarm centre access track. The span will cover one micro-paddock width at a time. We will pivot it at the end of each full length run to return up the other side. The parts were there for two spans and a centre feed, but that would cause problems with tractors and sprayers. A single span machine lets us move it fully out of the way of one side of the MicroFarm at a time.

What we have now is effectively a gantry that (almost) spans our micro-paddocks. It doesn’t have any nozzles yet, and we may not use the span pipes to carry water. We’ll only be pumping 4.8 L/s – a tenth of what the full machine used. So a smaller pipe will fill quicker and reduce drainage at the end of each shift. Thanks to the Ritchie family we have a critical part of MicroFarm infrastructure in place. It is five steps up from last year and our hand-shift mini-gun tied on a clapped-out rideon mower!
