Couldn't find exactly what I was looking for locally, so I cobbled together a combination 3 point hitch tooth harrow/seed row marker, for my 1025R tractor.
Had a single row cultivator laying around, so I removed the C tines added another 5 foot piece of angle iron. I used the existing holes where the C tines were attached and drilled a whole bunch more in the added angle iron to add points to.
Also in my left over parts bin I found a bunch of threaded rod cut offs collecting dust so I used them for the points.
...... and... no welding req'd... all bolt on stuff..
The added angle iron also serves to level the ground in preparation for seeding crops like onion seedlings etc.
The 5 foot width covers all tire tracks.
Seems to work fairly well.
