So the removable point one is the new version. They cost about $280au and the old ones just the boot cost $143au. they place the seed 75 mm apart and the fert 15mm below. We put them on our flexi 820 on 180lbs due to sheet rock in spots. From asking around about blockages basically the blokes in heavy mud /clay said they don't have any problems. I do know he makes a contour/ paralink version but im not sure about conservapak . Jason from rootboot is very helpful worth having a chat to.
Root Boot - Innovative Seeding Systems - ROOTBOOT
I have used stilletto, rootboot, primary single, agmaster.
Started with a Flexi 820 on 350lbs, Stillettos. Worked fine in sandy loam and sandy gravel. Soon as we hit heavy dirt the trouble started. With 350lb the tynes drag back and the seed boots point into the air and seed above the ground. Also in both cultivated and notill the fert tubes and sometimes seed plug constantly. Trialed rootboots that year on outer wings and worked fine running straight but plugged outer seed run when turning in clay. Jason said it was an operator problem. We said so you expect us to not seed 10% of our country??? We have to turn with the bar in the ground due to twisty breakaway country.
Next year bought a JD1820 with single shoot Primaries on 10inch, 550lb tynes. Works pretty well but we want double shoot for extra crop competition. This year we fitted agmaster paired row. Found to be pretty good, lost some due to rocks and the silly clips coming off. To their credit when I mentioned this at Dowerin field day they sent me 10 replacement points with new design clips. We had trouble with wheat and oat stubble blocking as the boots are wider and push up a bow wave of soil in front of the tyne. Mostly fixed by fitting agmaster strawguards on the front two rows. We are also making sure that no matter how heavy the crop we are cutting at beer can height. Where we cut high last year and sheep pushed it down flat was where we had trouble blocking. Standing tall straw was not too bad.
We also used more fuel as the agmaster puts a lot of steel in the ground so increases draft. I think the rootboot may be a bit better in this regard.I really like the tungsten on the agmaster as they look like new after 2500ha (6250ac)
Hope this helps.
Edit. Had another look at the photo of the new rootboot. It looks like they have changed where the seed exits, can't be certain but he seems to have changed it so the seed exits to the rear. The ones I trialed had the seed exits open to the side a bit. As soon as we turns to go around rockheaps, breakaways etc the runs on the outer wings plugged. Maybe Jason did listen to me after all!! Credit to him if so.
