Assuming equal weight per disc, a pull-type will pull significantly easier than a 3-point. If you handle the 8 ft, 3-point without any trouble, then you will certainly have no issues with the 10 ft pull-type. I use an 8-foot pull-type behind my 43 hp, 4wd tractor and it doesn't even know it is back there. The 6-foot, 3-point I had previously, pulled significantly harder. I like my equipment on the small side for my available power because it lets me get the job done before soil conditions are perfect. I personally cant stand 3-point discs, but there are many folks who dont know no better so you should have no problems selling yours. You will also notice significantly less fuel usage with a pull-type disc compared to a 3-point. The fuel is saved because less "work" is done with the pull-type, but the ground gets ready to plant sooner because all areas are worked to a uniform depth rather than some places not touched at all and others worked extra deep as occurs with the more ridgid 3-point disc. Pull-type discs are always adjustable on the angle so you can simply set it less aggressive if you are concerned with power. I can use my 8-footer at the most aggressive angle behind my 43 hp, 4wd in any field conditions, but I have to set it up at less angle behind my 20 hp 2wd. After the ground is worked a couple passes after plowing, even that 20 hp 2wd will handle the 8-footer at the steepest angle. I have yet to see a 3-point disc that I thought was worth more than its weight in scrap metal.
