Petty Plough
The Petty Plough was a steerable plough developed by brothers Frank and Herbert Petty of Doncaster, Victoria, Australia in the early 1930s.
Frank and Herbert Petty were orchardists, growing apples, pears, lemons, cherries and peaches. The entire orchard was cultivated. The Petty Plough was designed to plough between and around the fruit trees, working right up to the trees, eliminating the need for slow and tedious manual cultivation between the trees.
The Petty Plough could be pulled by two horses or by a tractor.
The Plough was fitted with lever and foot controls which operated four straight disc wheels. These were turned in and out of the trees as the operator desired. The wheels would sink into the ground about 2.5 inches, giving good control and preventing side slipping often associated with ploughing uneven surfaces. The cutting discs were on an extended floating arm, which followed the land they were working. Depth was regulated by two levers and the discs could be reversed to turn soil towards or away from trees. Soil was turned towards the trees in autumn and away from the trees in spring. This facilitated drainage in the wetter months and conserved water in the dryer months. The plough was manufactured in two types: light and heavy. The light weighed 7 cwt and the heavy 8 cwt 2 qrs.
It could be used as a single furrow, double furrow or triple furrow plough. The single furrow plough had one 23-inch diameter disc, the double furrow had one 23-inch disc and one 20-inch disc, while the triple furrow had three 23-inch discs.
"The Petty Orchard Disc Stripping Plough is the greatest labour saver of all time. It eliminates a lot of back-breaking work in cutting out the strips between trees. The operator is able to ride on the plow seat, thus sitting down and doing the job in comfort."
Frank Petty probably conceived the idea for a steerable plough, although the source of his inspiration is unknown. He invented many useful objects for use on his orchard. He developed and marketed the 'Whirlpool Spray Mix' a device not unlike a giant eggbeater which clamped to the inside of a drum of fruit spray, with a handle which when turned was designed to mix the spray.
On 10 October 1932, Frank made a 'Provisional Application' for a Plough and Cultivator. This lapsed in 1933.
