Aren't those considered chisels? Not for very deep work. killifer made hd stuff.

what i have used for mounting scarifier tines and light rippers are the u type wedge and clamp system all you need is a hammer to install them.

they can be made from normal flat bar stock or you can buy the factory made versions

I am new enough to dirt work that I dont know much of the proper terminology. I have some old books on farm implements but they are not very informative. I am learning more on this site from the people with knowledge. What is the difference between a chisel and a ripping tooth and their uses? I also am not sure if the Killefer should be called a ripper or an implement carrier, since it can be used for anything that clamps onto the tool bar. I have played with Cats for years but I am now getting a bit more serious about expanding my orchard and doing some road building on my rather steep land. This site is a great source of information. Thanks, Grant.

well a chisel point is shaped like a chisel. there are several style of points and what style you use depends on the soil conditions and what you are trying to do.

a ripper often has a fixed point ie the cutter is welded on. some are simply made by welding a piece of wear material such as bisalloy to the ripper shank or building the shank up with hardfacing welds others have bolt on or drive on tool points like excavator bucket teeth. some tools are called different things in other countries. thread taps for example what we and the brits call a plug tap american machinists call a bottoming tap, what they call a plug tap has a one thread width taper where as a bottoming tap is square cut which does make sense as it cuts right to the bottom. what yanks call wrenches we call spanners. what your calling a killifer would be called a tool carrier. particularly if its mounted on wheels.

This is good. I am starting to learn a proper vocabulary. Yes, I agree it is a tool carrier on wheels. Nothing on the data plate says tool carrier but I figured it out earlier. Over the next few days I hope to post more photos and ask more questions. This forum is great. Thanks. Grant

the widest variation in points is for what are scarifiers these are for weeding interrow areas and breaking up soil after ploughing which is done after ripping.

a scarifier usually will have spring tines often curly tines and there are a few different points to choose these are normally stamped out of high grade steel sheet or bar stock

Killifer was a brand name of tillage tools sold by John Deere. And with wonder of google Killifer Manufacturing Company was started in 1892 in Los Angles Ca. John Deere purchased the company in 1937 and operated the LA plant until 1969.

yes originally deere was a machinery dealer before they started manufacturing ploughs

i thought John Deere developed the steel walking plow in 1837?

Yep!  John Deere was a blacksmith and went from the cast plow to a steel one that scoured well in the soil. Seems like he sold over 1000 plows his first year in business and the rest is history.  His philosophy was to sell quality equipment and not cheap stuff.  He learned to polish the plows by observing his father smoothing sewing needles in his tailor shop.
