disc harrow weight vs width

[tw30]

I've been looking on athens plows website and it seems like you can either get a wide disc that's light or a narrow disc that's heavy. Im looking at the model 66 disc 15'3" weighs 2600lbs

I want to know in unbroken ground how many more passes it would take then say their 187 model 14' that weighs 5700lbs

Im beating there's a significant price difference to. 3pt vs a transport.

You really cant compare the 2. Ones a lightweight pulverizing disk, the other a heavy breaking disk. Kinda like comparing apples to oranges. Some soil conditions such as heavy grass sod and dry weather or hard packed soil on a cattle operation, the lightweight disk cannot make enough passes to equal the breaking disk performance. On the other hand, under ideal conditions it wouldnt make much difference. But who here always disk in ideal conditions. If your in the market for one, get yourself a mid range disk and dont look back.

Might I ask why you don't want to plow first and then use the lighter disk?

What size tractor will you be using?

 

[tw30]

Ford tw30. Has 143 dbhp. Couldn't a ripper be used on virgin soil to loosen it or would it be better to use a mold boas to losses the soil. Rippers are easier to find locally than a plough and cost less . I could robably pull a 3 shank ripper. I know I could pull a 20ft disc. But I figure a 14-15ft would be more ideal. Puts less load on the tractor and easier to transport

A v-ripper or chisel plow is what we use for deep tillage and to loosen soil. Your tractor will handle a 20ft disk easy. It will also sink a 5 shank v-ripper with ease.

You mean like a john deere 915 or a older international vripper. I see alot of repainted international vripper on tractorhouse priced pretty good. Ill look into those more.

 

[pjbci]

Yes. Some of those international rippers had shorter shanks on them. You could probaly pull a 7 shank depending on your soil type. Heavy clay content is like concrete down here in the fall so we always stuck with a 5shank for our 145 hp tractor. But during the spring when ground was softer it would drag the frame of our long shank ripper.

HEavy disc's with larger blades will have larger spacing and used as primary tillage. Lighter disc's will have smaller diamter blades and be closer together for finish tillage.
