I own a few acres around my house which I manage with tractor/ mower/ digger/ dumper etc as well as smaller tools like chainsaws. When these breakdown you often just need the right part, not a mechanic. R.S Components stock a vast range of fittings which an amateur can identify by the picture or part number, without knowing its name. This week I was missing a little roller arm from a contact switch that tells a mower that its hydraulic grassbin is back in position. £80 from the supplier for a new switch: £3.50 for the roller from R.S. which arrived in 24 hours. Transformational!
