Tractor Tillers
Tractor Tillers – Origins and How They Work
By Jason Gorka
It was Arthur Clifford Howard who invented the first powered rotary tiller while working on his father’s farm in 1912. He used a steam-generated tractor engine as the power source and this method of tilling to leave the soil just as smooth and unpacked as if it had been done by hand.
The first design that Mr. Howard created ended up throwing the soil off to the side when it cultivated until he redesigned the blades into an “L” shape and set them on a flange to provide more tilling power.
In the early spring of 1922, Mr. Howard formed an independent company by the name of “Austral Auto Cultivators Pty Ltd.” that later went on to be called “Howard Auto Cultivators”.
Tractor Tillers Have British Beginnings
Mr. Howard based his business out of a northern section of Sydney but would soon move on to Britain in the late 1920′s and become the founder of “Rotary Hoes Ltd.”, in east Horndon, Essex by the summer of ’38.
Since then rotary tillers have become a popular small tool for working the soil of smaller gardens while its larger counterpart, the tractor rotary tiller continues to be used by the owners of larger farms and land areas.
Types of Tractor Tillers
There are different types of tractor tillers that are able to till through varying degrees of soil.
A standard rotary tiller is similar to design and function in all brand names. It sits on a box section steel frame with pin brackets that are bolted to the perimeter of the framework but can still be adjusted for various ground tilling levels.
Standard tractor tillers have a forward pulling motion that separates the soil behind the blades, but the digging action is shallow. Rear tine tillers work better at cultivating ground for gardens and landscaping.
Most standard tractor tillers are equipped with up to 540 rpms of PTO and provide slip-clutch protection to lessen driveline damage. These tillers also have universal driveline joints and rotor shaft bearings with greased fittings that enhance the life of the equipment.
Oil Bath Keeps Tillers Working Smoothly
Both an input gearbox and a side gearbox are installed for maintaining the transmission.
The gear fittings are bathed in oil during each rotation to ensure that all tractor tiller parts run smoothly and efficiently.
Among some of the other features included with standard tractor tillers are an adjustable rear shield to help the tines work more thoroughly through soil beds, adjustable skid shoes that can be set in four positions for terrain depth, and curved tine tips that are fashioned from durable steel for maximum tiller performance.
The heavy-duty models also feature a gear drive with high-speed tines for making the perfect till in one pass. These heavy-duty tractor tillers can be supported on the I and II category, 3-point hitches.
Standard tractor tillers are perfect for cultivating rough, wet, and rooted ground.
Reverse rotation tillers have all the same workings as a standard tractor rotary tiller but they till in the opposite motion of the tractor. This method provides a deeper, more intense line of tilling and is generally used to plow smoother, softer terrain.
Both the standard and reverse rotation tractor tillers can be purchased in the gearbox or the chain driven option.
