The primary function of engine oil is to reduce friction between the countless moving parts within the engine. This friction, if left unchecked, can lead to wear and tear, resulting in costly repairs. Engine oil not only lubricates but also cleans the engine, preventing the buildup of sludge and varnish that can impede performance. Additionally, oil helps in sealing the gaps between pistons and cylinder walls, preventing combustion gases from escaping and optimizing engine power.

Historically, ridge ploughs were simple wooden or metal tools operated manually. These early models were affordable, but their efficiency was limited. Over time, manufacturers began to innovate, introducing more advanced materials and designs. The transition from traditional hand-operated ploughs to modern mechanical ridge ploughs has been a game-changer for agricultural productivity. Today’s ridge ploughs can be attached to tractors, allowing for much more extensive and efficient tilling of land.
