    HP to Disc Ratio?

    Is there a good HP/weight ratio that is used for a Disc? I'm looking at two models offered by JBar Manufacturing. I'm looking at their models since I will be using them only a few times a year. They look built fairly well and are cheaper than the landpride, king kutter etc.

    I'm looking pretty hard at the B700 with a 6' wide cut. They weigh in at 850lbs. Is that too heavy? The step down is actually 6 1/2' wide and 560lbs.

    Untitled Page

    Probably going to throw in a rotary cutter as well and he said he can get a 5' heavy duty dual rear wheel rotary cutter and the heavy duty B700 disc for 2600 out the door.

    Any and all input is much appreciated

    A disc is a poor mans attempt at doing work a tiller can do,,
    why buy a disc when you already have a tiller??

    If you do get the disc, get a moldboard plow at the same time, they are used together,,,

    Disc is to be used down at my Hunt club. Don't really need a perfect seed bed that my tiller can produce, plus I don't want to tear up my tiller down at the Hunt club. The disc would be faster to prep an ok seed bed.

    Disk size will depend more on weight/traction than HP, IMO.

    Your 2032 should easily be able to lift 850 lbs on the 3 point, so I don't think it's too heavy.
    Also, weight is your friend with a disc. More is better. 6' should not be a problem.

    Very true. I hope someone with a similar weight/size tractor with a set of discs will provide some insight

    The weight of the disk is not the issue. Traction is your main issue. I use an 8ft tandem disk that weighs 750# and have to use 4WD on my 4066R. Leave the bucket on the loader and maybe fill it with dirt or something heavy for better traction in 4WD. The second thing is to make sure that you have enough width to cover your tracks when you have it angled. My 8ft disk barely covers my tracks when angled and the tractor is 6ft wide. In A drive, you will have enough power, provided you have the traction.

    Apparently you haven’t used a disc much and are not aware of the benefits of using them. They have a place in tillage work, where a tiller does not. A tiller is designed more as a finishing tillage piece of equipment. I have farmed with discs and know millionaire farmers who use a disc. It is not a “poor mans” piece of equipment.

    I only had access to an 8' transport disc, the 2038 struggled a little bit in really wet soil. You should be fine with a 6'.

    Wow, you were able to pull that 8' pull-type offset disk with a 2038R? That soil looked wet too! I'm quite surprised.

    A pull-type (wheel) disk will be MUCH heavier than a 3 point mounted disk. More weight helps the disk to cut deeper...which is good.
    However, it also makes it pull harder.
    Looking at the Rhino Ag website, most of their 3 point disks are about 35 lbs per blade, and their pull-type wheel disks are about 95lb per blade.
    Significantly different.

    I also think this contributes to the conflicting views in earlier posts about the effectiveness of a disk. The "millionaire" that uses a disk almost certainly uses a heavy pull-type disk. There isn't much more effective and efficient at covering lots of acres than a heavy pull-type disk.
    ...and folks who know me recognize how much I love my tiller.
