Pulling a 10 ft. disc

[jenkinsph]

I used to have a 6' Amco offset disc that neither of the above tractors above could pull beyond second or third gear.

With larger blades and plenty of set you can make a sign and cut deeply, otherwise your just rolling across the ground.

What is the proper speed?

I am going to be discing up some pastures for a seedbed next year. I have a 12' 32-20 hay king that I will be pulling with a John Deere 5525 (75 PTO).

Any tips would be appreciated.

Thanks,
D.

I like to travel 4-5 mph when discing. Can go a little faster up to 6 mph but then can get too rough and disc doesn't penetrate the ground as well. Pasture is difficult to disc because the ground to too hard in my area to get good penetration. What do you plan to plant?

Last year I converted CRP land to crop land. Mowed and baled the grass off in the fall. In the spring sprayed Round up (or equivalent) on the short grass and then planted/drilled in the Round up ready soybeans. Sprayed Round up one more time later. Perfectly clean beans with no tillage. This is a common approach to planting crops in CRP. Otherwise it is labor and machine intensive.

Pics of when I first bought the disc. Tractor without weights and FEL.

thats some disk, what did that run you?

I don't remember for sure, but I think around $5k.

Guys! why are your disks so big for the small size of your tractors! I got a JD 6420 with a 637 Disk 12Feet wide. 18 feet with like 50 horse are you kidding me?

I would be glad to pull a 36 feet with my tractor.

Edward S,

That was my thoughts,

I would rather pull a more narrow disc with larger blades and more weight per blade. Suspect less maintenance with this too. Less passes to get the same results.

I looked into buying a disc for my compact 4520 about a year ago and considered an 8ft pull type Frontier 1508. Cost was around $7000 IIRC, anyway I decided the compact tractors were not big enough to make this worthwhile and passed on it. The Deere 673 tiller (6ft, 7" penetration) is a better match for these higher hp light weight tractors IMO.

It seems that all I see on here are small garden tillers and makes me wonder why there are so few large tillers? With larger diameter rotors these can be pulled at a faster ground speed and till 8" to 11" depth. This would be a better match for the high hp to weight ratio compact/utility tractors such as the 4000 and 5000 series tractors. The added bonus is the tractor doesn't need to carry as much weight all the time with this method, instead use the pto to transfer the hp to the ground.

If I had it to do over again I would have selected the Deere 681 tiller for the 4520 (60hp) and could pull it about 1.5 to 2,0 mph with good results. i would think a 5525 could pull an 8' tiller with larger rotors slightly faster.

My 5525 pulls my 12' disc OK. You can tell when you don't have it in 4wd - that is for sure. That is the biggest disc I would consider with that tractor.

If I had to do it over, I would probably buy a used disc (lots of them out there in this size) and a tiller. Probably a CCM tiller. I may still buy a tiller, just have enough projects going on right now.

I suspect my 4520 with R4 tires would have a hard time pulling much more than a 8' with decent penetration. Not enough traction - maybe with R1s and a lot of ballast.

I don't do much ground prep - so not a big deal. This winter I will be using my disc to clean up some pastures and overseed.
