The disk harrow is used first to slice up the large clods left by the mould-board plough, followed by the spring-tooth harrow. To save time and fuel they may be pulled by one tractor; the disk hitched to the tractor, and the spring-tooth hitched to, and directly behind, the disk.
A plough or plow (both pronounced / p l aʊ /) is a farm tool for loosening or turning the soil before sowing seed or planting. [1] Ploughs were traditionally drawn by oxen and horses but modern ploughs are drawn by tractors. A plough may have a wooden, iron or steel frame with a blade attached to cut and loosen the soil.
A disc harrow is the preferred method of incorporating both agricultural lime (either dolomitic or calcitic lime) and agricultural gypsum, and disc harrowing achieves a 50/50 mix with the soil when set correctly, thereby reducing acid saturation in the top soil and so promoting strong, healthy root development.
A spring-tooth harrow is a type of harrow, and specifically a type of tine harrow. It uses many flexible iron teeth mounted in rows to loosen the soil before planting. A drag harrow more specifically refers to a largely outdated type of soil cultivation implement that is used to smooth the ground as well as loosen it after it has been plowed ...

In the mid-1930s Frank and Herbert Petty of Doncaster, Victoria, Australia developed the Petty Plough. This steerable plough could be pulled by either two horses or a tractor and the disc wheels could be steered in unison, or separately allowing the operator to plough the center of rows as well as between and around orchard trees.
The Howard patent plough was a great success and made in huge numbers. However a diverse range of different types of agricultural equipment was made, for example an advert in 1891 lists their famous ploughs and harrows plus disk harrows, horse rakes, mowers, reapers, cultivators, land-rollers, hay presses, straw trussers, grass harrows, horse hoes, vine cultivators, sheaf binders, scarifiers ...
This redirected the plough's resistance into downward force on the drive wheels, which enabled Ferguson's tractor to be much lighter and more manoeuvrable than earlier models of farm tractor with equivalent tractive force and traction. As a result his tractor could operate on soft ground and caused less compacting damage to the soil in ...
