Cultivator

**History of Cultivators:**
– Soil scratching for weed control dates back to ancient times, initially done with hoes or ploughs.
– Harrows were created by grouping hoes together and utilizing draft animal power.
– The powered rotary hoe was invented in 1912 by Arthur Clifford Howard in Australia, leading to the establishment of Austral Auto Cultivators Pty Ltd in 1922.
– Tractors in North America transitioned to smaller, lighter machines in the 1910s.

**Industrial Use of Cultivators:**
– Commercial cultivation is mainly powered by tractors, particularly row-crop tractors.
– Industrial cultivators can vary in width from 10 to 80 feet, with hydraulic wings for easier road transport.
– Various cultivator types are employed for field preparation and weed control.
– They can be trailed behind a tractor, mounted on a three-point hitch, or attached to a frame beneath the tractor.

**Functionality and Types of Cultivators:**
– Cultivators are utilized for secondary tillage in agriculture, stirring and pulverizing soil before planting or during crop growth.
– They disrupt weeds near crop plants without disturbing the entire soil surface.
– Cultivators can be self-propelled or attached to two-wheel or four-wheel tractors, with different power mechanisms.
– Rotary tillers combine harrow and cultivator functions into a single machine.

**Challenges and Modern Adaptations:**
– Herbicides have significantly reduced the need for cultivating in commercial agriculture for weed control.
– However, herbicides are not always suitable, especially in organic farming practices.
– Wise management involves exploring alternative methods like mechanical cultivation alongside herbicidal weed control.
– Row crop cultivators and garden cultivators are designed for specific applications and weed control methods.

**Variants and Trademarks of Cultivators:**
– Rotary tillers are popular for large vegetable gardens, typically powered by a petrol engine.
– Mini tillers provide cost-effective alternatives to four-wheel tractors.
– Two-wheel tractors, also known as walk-behind tractors, offer versatility for various farming needs in different terrains.
– Specific cultivator models like the Howard Rotavator and Pubert SAS cater to unique speed adjustment and farming requirements.
