Planter marker orientation - curved outward or inward???

andy r · Apr 16, 2017

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.

Sure. Give it a try. Seems like years ago marker discs threw in. Then somewhere that changed. Maybe with the JD 7000 series?

They are that way to cut better in no-till. Go ahead and change them. Ours are pretty fine haired getting them to cut enough to see. Or cutting a furrow to deep.

I find posts like this interesting, showing regional differences. May I ask what part of the country you are in?

Around here, (north central ND) you could drive for HOURS and hundreds of miles in planting season (we're not quite there yet) and be hard-pressed to see a single planter/drill/seeder with markers, nearly ALL GPS/autosteer.

My 1760 throws in. It's a no till. I end up changing the pitch frequently, sometimes field by field based on conditions. I can plant so much better by marker than GPS, so I use both. I snap my line to start with the GPS and use the markers from there on out checking the GPS continuously to make sure it is all in line for spraying by GPS later on.

I would think in hard no till ground here the marker throwing out would put lots of torque on the marker arm. I rarely break sheer bolts on markers. I wonder if it varies regionally due to soils.

My 7200 Deere with regular smooth opener disks pushes out. I looked into converting to notched disks for no till and was told by the Deere parts man it would take all new hardware on the end of the marker because the notched disc will be pulling in.
