My Kinze planter has always had the marker disks set so they throw the dirt outward. The blades would be oriented like those on the front gang of a disk. Now I am seeing Kinze planters with the marker disk blades set so the dirt is pulled inward towards the planter to make the mark. Just got to thinking that sometimes the marker disk will bury itself if it hits an ammonia fertilizer slot. A few times I have even seen it push up on the center pivot of the flat fold markers while the marker disk is trying to stay in the ammonia slot. If I would turn the marker blades around it wouldn't push up on the center of the two piece markers since the blade would be pulling outward. Looks simple to change them - loosen four bolts and turn the blade around. Might have to end for end the mounting brackets. Maybe they wouldn't dig so much. The ground last year was soybeans. Planting no-till corn. Advantages or disadvantages????? Thanks.
