Which style coulter?

Hello,

Today I finally mounted the coulters on our 3-14 Oliver plow. The blades are in various stages of wear and they all need to be replaced. They are the type with a 4" center hole, 5 1/4" 4 bolt BHC and I believe were 15-16" when new.

We will be using this plow to open ground that has not been worked in over 20 years, we need the coulters to do a good job cutting through small roots and whatever else will be in a field that hadn't even been mowed in over a decade previous to the last two seasons when we've been bush hogging the ground.

I saw that Agri-Supply has quite the selection, what would work best for our situation?

Any and all advice will be greatly appreciated!

Thanks,

Erik

There's not too much trash on top, we mowed the field down two year ago and what was on top has decomposed pretty well. It was more than grasses in these fields, we mowed down bushes and small trees, some over 10' tall with +2" trunks.

I'm more worried about root mass in the ground causing problems.

Thanks for the reply!
