Difference between a spring tooth and a spike harrow

I know both a spring tooth and spike harrow like a harrowgator
are used as finishing tools, but whats the pros and cons of
each? Ive never used a spring tooth, only a harrowgator.
 
Pa had a spike tooth harrow, I had a spring tooth harrow. I always figured I could set mine to go through heavy trash without leaving bunches better then he could with his spike tooth. If no heavy trash there is no difference in performance.
 
Spring tooth could be set to go deeper and work the top layer of soil. Spike tooth or drag harrow would just smooth out the top. Neither one worked very good if there was still a lot of straw or stalks left on top.
 
What is the difference between those style harrows and a field cultivator? I use a field cultivator that is spring tooth on the front and has sturdy spike tooth drags on the back as levelers. Works well.
 
Same principle. Spring tooth and spike or drag were common decades ago. Modern field cultivators incorporate the same principle with the two often combined into a much larger, heavier, higher capacity implement.
 
You can start a hour sooner in the morning with a spring over a spike harrow---Tee

A spike tooth will break up large clods and leave a smooth surface, working the ground down. A spike tooth fluffs the ground, working deeper ground up, works well if the ground is still a bit wet to help it dry faster.
 
Also a spike tooth harrow is virtually useless on stony ground. A spring tooth will dig down between the stones.

We have some ground that looks like a patio made of tiny flagstones.
 
Put the spike tooth behind the spring tooth for a nice seed bed. I have used both pulled in combination behind the field cultivator,
