I have used the Mohawk closing wheels, and more recently added some Zipper wheels, for several seasons now in both no-till and tilled ground, and have planted corn, soybeans, and milo with good results. I like how the wheels still maintain the same depth of penetration even if I’m a little too heavy on the down pressure. No flipping chunks of soil and seed out.
In watching the planter run this spring, it seems like the Zipper wheel might have a little faster “sewing” action than the Mohawk, meaning when the soil was a little heavy or no tilling into fall killed sod, the Zipper rows seemed to have a little more fluff to them.
In normal no tilling situations, both wheels performed great.
An advantage for the Mohawk is if your planter closing wheels are in good shape, you swap the rubber tire for the Mohawk and you’re ready to go at an attractive cost.
I don’t see how anybody can go wrong with either wheel.
