A backwards disk chisel, (chisel disk?) to make food plots

I've seen his inpliment before, but, what does the disc on the front do? It almost looks like when set straight, it almost is a gauge wheel?

It pierces the sod in advance of the chisels. Makes for smaller clumps. I always wondered if it would make more sense to have the chisels in front and angled disc gangs in back.

So, that APP is almost the same as what I got, although mine is an older Massey/Ford/deerborn/who knows. It does a good job, and actually is better heavy duty, as long as A, you going at a medium slow speed, and allow the springs to trip and reset; and B, you don't turn to sharp with then down. Replacement complete tine assemblies, with springs, rippers, and tips are like $111, so not cheap, but if you do need to replace 1, it's not the end of the world.

It should pull those rocks up towards the surface, for gathering, piling, ect.

What is APP?

What is APP?

All Purpose Plow, Bushhog and maybe another Lienbach? call it APP

I haven't used mine in sod, just sand pasture that I think original owners goats ate the top layer of sand... but it did work well on pulling roots, and breaking the soil up. I could see the disc working in a heavy existing sod.

In my thread on mine, trying to ID it and parts availability, it was mentioned that some of the newer, lighter, ones use a narrower tine, and either don't have replaceable tips, or use a non standard through bolt. I'd have to go back, but I think mine are just under 3/4" tines, but some are only 1/2?

This is exactly what I was wondering about building. Figure some wide spaced serrated discs and it could in theory mulch sod pretty good.

Don’t quote me on this, but I think we have a cultivator at work that’s Disc-chisel-disc. Been a minute, I’ll look closer next time I go past it.

Straight discs in front of shanks is to cut grass, weeds, corn stalks etc. so they are less likely to wrap around and plug the shanks.

Angled discs are for stirring or turning the soil. Disc rippers like Case IH 870 or 875, Deere 3720, Kuhn, Dominator, etc. typically have angled blades in front and behind the ripper shanks to cut or size trash and help bury trash. These implements are heavy, our 18 ft is around 20,000 lbs. I think smallest size is 12 or 14 ft so not something you will pull with 5000 Ford.

Depending on tire type, soil type, tractor weight you may struggle with 7 ft chisel at 5 - 6” depth.
Huge difference in tilling light loam vs heavy clay.

Great insights. We also have a dominator set up that way at work, boy it just shreds stubble.

My tractor has 18.4-30 R1s that are basically new. Loaded rears, and with the loader she comes out around 9-10k gross. Not a light gal thats for certain.
