A tractor is a vehicle designed to provide high torque at slow speeds for hauling trailers or machinery used in agriculture and construction. It provides power for mechanizing agricultural tasks like tillage through implements that can be towed behind or mounted on the tractor. A cultivator is a farm implement used for secondary tillage through frames that pierce the soil or machines that use rotating disks or teeth to till the soil similarly. A shovel is a hand tool used for digging, lifting, and moving bulk materials like soil, consisting of a broad blade fixed to a medium length handle, with blades typically made of steel or hard plastic and handles usually made of wood or fiberglass.

1. A tractor is an engineering vehicle specifically designed to deliver a high tractive effort (or torque) at slow speeds, for the purposes of
hauling a trailer or machinery used in agriculture or construction. Most commonly, the term is used to describe a farm vehicle that provides
the power and traction to mechanize agricultural tasks, especially (and originally) tillage, but nowadays a great variety of tasks. Agricultural
implements may be towed behind or mounted on the tractor, and the tractor may also provide a source of power if the implement is
mechanized.

2. A cultivator is any of several types of farm implement used for secondary tillage. One sense of the
name refers to frames with the teeth(also called shanks)that pierce the soil as they are dragged
through it linearly. Another sense refers to machines that use rotary motionof disks or teeth to
accomplisha similar result. The rotary tiller is a principle example.

3. A shovel is a tool for digging, lifting, and moving bulk materials, such as soil, coal, gravel, snow, sand, or ore. Shovels are
used extensively inagriculture, construction, and gardening.
Most shovels are hand tools consisting of a broad blade fixed to a medium-length handle. Shovel blades are usually made
of sheet steel or hard plastics and are very strong. Shovel handles are usually made of wood (especially specific varieties
such as ash or maple) or glass-reinforced plastic (fibreglass).
