Midwest Machinery supplies several brands of travelling irrigator, with Williams being the most popular. The other brands we can supply are Numedic and Briggs.

The Williams Greenback Spider model features a new simple speed change procedure with a choice of five travel speeds, allowing greater control of effluent application depths. This in turn allows greater control of soil absorption rates, optimising the benefits of the natural fertiliser. The Williams Green back travelling irrigator is known for its reliability after many years of harsh use.
