I am going to try a situation where we are going to use a discbine-type blade arrangement.........and I noticed that discbines apparently only have two (swinging) blades per discbine blade carrier.

Since my situation would not have the blades cutting near to the ground, or near to each other, I was thinking that I would use sickle sections bolted to the discbine blade carrying unit........and put on as many of them per unit as the "disc" would hold.  Objective would be to give the cutters as much chance as possible to cut plant stalks when point of cut is higher up on the plant, and plants would obviously be less rigid.

Any operational reason for limiting the number of blades per blade carrying unit, other than meshing with the unit beside it?

Thanks.
