I understood the theory but couldn't quite get the details. Thank you for the very detailed information. The pictures are great. My experience with tractors is pulling logs and pushing dirt, very cool to see the other side of tracked machines

i knew they had rippers and scarifiers didnt konw there was cult wheels, cutter bars etc quite the range certainly enough to rival the Ferguesson system of 3 point lif implements that is pretty much the way its done today.

Great information. It clears up questions that I had on several old pieces of equipment. Thanks. Grant.

Neil, d4jim should clear up your question, he's a real farmer. But i think theres some regional parts of the farming community involved and what they called different methods of farming. Back in the day if a farmer/fabricator fitted up a tool to the bar and it did the job it was farmer fixed.

I have a question - what's the difference between a lister and a furrower and a ridger. They all seem to be roughly the same shape and seem to produce a similar outcome. Is it just the size and spacing?
 

Neil, if you get 2 farmers talking about something they usually have 3 opinions. With that being said...................
A lister is a farm implement that creates a furrow(s) in which the seed is planted in the furrow between the ridges formed by the lister all in one operation.  It was common before chemical farming as the cultivators could be used on the ridge to control the weeds.  Now most use a planter that buries the seed just below the surface of the ground with no ridges or furrows.
A furrower is just that in that it creates a furrow or ditch(s) and often used to direct water in gated pipe irrigation systems. 
A ridger forms ridges and piles the soil in a ridge on top of the ground. Of course it has to get the soil somewhere so it forms furrows on each side of the ridge!!!  The ridge is often used for planting such crops as potatoes etc.  Some planters actually plant the seeds halfway up on the ridge. 
The above is not the complete Gospel as there are many variations of each.
