I am looking to buy a 10-12 ft transport type disk for finish disking after breaking the soil up with an offset disk. My soil is a very sandy loam type soil. I have read on the forums that the older IH and Oliver disks were very good, fairly heavy weight disks. I am also going to look at a Deere 111 disk which may not be as heavy as some of the older disks. With a light, easy to fracture soil, would a lighter weight disk produce tend to provide good leveling and finishing?

Nobody answered so I will get the ball rolling. I live on Houston Black Clay and it is either a sink hole or a rock. Trick is to sneak in between the extremes and do some farming.
In heavy clay you have to wait till it dries out somewhat. Definition of that is that it doesn't readily stick to your implements. Since the soil is dense, it takes a lot of weight to get some depth.
So on my 7' Offset I have 4 JD rear wheel weights at about 150# as I recall and on my 6' tandem disc I have 4 ea Ford rear wheel weights at about 85 each. This helps the implements do the job that has to be done.
So for me, weight makes it work. For you I know not of the soil, but common sense tells me that you don't need a lot of weight.
But as I said, I kicked this off and one of the sandy loam type soil guys will chime in.
HTH,

I have a little IH disk with a narrow and it does a nice job 37o I think
Thanks for the reply mark. I don't need disc scrapers as my soil does not tend to stick to anything. I guess if I could always add some weight if needed. I am also interested in knowing the difference in how larger or smaller diameter disc blades perform by comparison. I think the deere 111 that I want to look at has 20" blades in front.

As big as you can get is how I feel. Since a good part of what you plow with your harrow is on top aka above the surface (undisturbed dirt prior to tillage), I don't like the axles limiting my ability to cut as deep as possible. Getting the 20 give or take dishes solves that problem. 6" is where I like to go, below the surface when/if I can.
For a follow up I use a JD chisel harrow with shanks on 9" centers and 10" sweeps. Attached to that are 3 rows of spring fingers. I have posted pics of it on here in the past. It's home made in that I added the spring fingers for the smoothing effect and saves a trip with the spike harrow.
This makes for 2 passes and you go from dormant dirt to a prepared seed bed ready to drill.
