Seed grading history
1915 - Wet Wheat Pickler
1915 : Hannaford Wet Wheat Pickler
Designed to improve efficiency and overcome drudgery.
1923 : Hannaford 'Ideal' Dry Pickler
Designed to use dry seed dressing such as copper carbonate, which replaced wet pickling. Could handle 35–40 bushels per hour.
1927 : Hannaford 'Ideal' Combined Grader and Dry Pickler
Designed to provide combined processes of grading seed and pickling it with dry seed dressing. This was the first machine of its kind on the market. Could treat 35–40 bushels per hour.
1929 : Hannaford-Carter Model 'K' Wheat Grader, Separator and Dry Pickler
1929 - Model 'K' Wheat Grader
Designed for contract seed grading, incorporating the Carter Pocket Disc Barley and Oat Separator. Mounted on a motor truck, thus making it mobile, the operator travelled from farm to farm to grade and pickle farmer's grain for a small nominal charge and no capital outlay by the farmer. Had a capacity of 75 bushels of wheat per hour.
1932 : Hannaford-Carter 'Junior' Wheat Grader, Separator and Dry Pickler
Designed as a farmer's plant incorporating the Carter Separator Pocket Disc. Comprised all the essential parts of the larger machine, and maintained the same high degree of efficiency. Had a capacity of 25–30 bushels of wheat per hour. This machine was regarded by wheat farmers as a highly efficient plant.
1934 : Hannaford-Carter Model 'M' Wheat Grader, Separator and Dry Pickler
Designed to provide increased capacity for contractors. Being mounted on a motor truck, the machine travelled from farm to farm grading and pickling farmer's grain for a nominal charge. Had a capacity of 130–150 bushels of wheat per hour. This machine had incorporated within its framework the Carter Separator pocket disc as well as increased separation by a large cylindrical screen.
1935 : Hannaford-Carter Grass Seeds Machine
Designed to incorporate the Carter Separator Pocket Disc. Enabled the growers of small seeds and legumes to grade seed on-farm and sell direct. This machine was used to grade all pasture seeds as well as cereals. It was specially designed with large winnower and airzone apartments for accurate grading of fine seeds. Cylindrical screens were provided with special apparatus to prevent them clogging.
1950 : Hannaford-Carter Model 'M' Seeds Machine with Dry Pickler
Designed to incorporate in one framework a machine to carefully grade a large variety of seeds grown in Queensland and southern States, as well as apply dry seed dressings. Mounted on a motor truck, this machine was transported to the farm by the contractor where the seeds were treated instead of being sent to a warehouse, making the plant a mobile seed-cleaning warehouse.
