The Ferguson Windmill is very sturdily constructed and has been designed to give a long life of useful service. The simplicity of design makes for fewer things to go wrong and therefore you can expect many many years of trouble free running. The tail-less fan and pivoting head run on high quality regreasable ballraces. The crank bearing is also regreasable. The pump is constructed from non-rust materials, i.e. bronze body - stainless steel pump rod - leather washers and stainless steel inlet valve in a brass body whilst the mast, pivoting head, blades, fan arms, screw anchors, etc. are all hot dip galvanised.
