Cultivators are usually either self-propelled or drawn as an attachment behind either a two-wheel tractor or four-wheel tractor. For two-wheel tractors, they are usually rigidly fixed and powered via couplings to the tractors' transmission. For four-wheel tractors they are usually attached by means of a three-point hitch and driven by a power ...
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. The result is a smooth field with powdery dirt at the surface.
A 4-foot drag harrow A larger, 12 foot drag harrow simply uses three four foot sections that are connected. A drag harrow, a type of spring-tooth harrow, is a largely outdated type of soil cultivation implement that is used to smooth the ground as well as loosen it after it has been plowed and packed.
A few farms did invest and used Caterpillar tractors to move the outfits. Tractor-drawn combines (also called pull-type combines) became common after World War II as many farms began to use tractors. An example was the All-Crop Harvester series. These combines used a shaker to separate the grain from the chaff and straw-walkers (grates with ...
The All-Crop harvester or All-Crop combine was a tractor-drawn, PTO-driven (except the All-Crop 100 and the All-Crop SP100) combine harvesters made by Allis-Chalmers from the mid-1930s to the early 1960s.
Typically, rollers are pulled by tractors or, prior to mechanisation, a team of animals such as horses or oxen. As well as for agricultural purposes, rollers are used on cricket pitches and residential lawn areas. Flatter land makes subsequent weed control and harvesting easier, and rolling can help to reduce moisture loss from cultivated soil.
Forage harvesters can be implements attached to a tractor, [4] or they can be self-propelled units. In either configuration, they comprise a drum (cutterhead) or a flywheel [5] with a number of knives fixed to it that chops and blows the silage out of a chute of the harvester into a wagon that is either connected to the harvester or to another vehicle driving alongside.
Around 1920, as IH's motor cultivator died, a team of IH engineers had evolved the motor cultivator into an all-purpose tractor, replacing the horse in every job including cultivating. [5] By 1923, [3] [6] they settled on a configuration, and their informal name for the project, the "Farmall", was selected as the product's official name. [3]
