FMJ; those are not nice words you are calling me. Do I call you Names that should not be posted on this type of site?
Ploughs come in many different sises. The use of a plough requires no great skill. In the farm lands of the Prairies almost every farmer had a plough. Granted very few were of the three point hitch variety as the tractor with a three point hitch at that time were not common for various reasons. The major one being to small. Most were a draw bar pull type pulled by tractors that did not have adjustable wheels. All had adjustments that the farmer of day knew how to use and adjust to suit his tractor and the conditions he was ploughing in. There was no resident Plough Guru that traveled the country to set up ploughs as all the residents were gurus!
Ploughs have evolved to suit different needs and different means of pulling over the years. What worked best for a two bottom horse drawn plough may not be compatible to a plough being drawn at probably three times the speed by some of todays larger tractors.
And yes they did leave dead furrows but that is quite common when the fields get a little larger and driving across the headland gets tiresome because it is not productive time.
Does any knowledge that is not within your ken cause you so much angst you must call people disgusting Names?
Most of the Prairie Farmers had loaded tires plus wheel weights!
