Mulch finishers

I am looking for opinions on these. Any brand better than another? I have a 72 JD 4320 to pull it. What size can it handle in heavy clay soil?
 
Are you talking about a 'pulvi mulcher'/roller harrow? if so,a 4320 will handle 16 ft(teeth down) easily.I like my Brillion 'camel back' the best.
 
I think your talking about the more modern finishers with a disk gang then field cultivator shanks with some type of leveling on the rare. With your JD 4320 your going to be limited to a 13-15 foot finisher. Truthfully a 13 ft. will more than likely be it in heavy soils. You need to maintain ground speed for them to work best. The require about 10 HP. per foot.

As for brands. JD, Sunflower,and Landall make good finishers. You want a new enough one for the disk gangs to throw the dirt in rather than out like the early models did. They do a better job leveling. The older one would throw the dirt out past the edge of the machine and you can easily end up with ridges in your field. I like a heavy harrow for clay ground. The newer five bar flexible harrows work real well. The top of the line would be the three bar with a rolling basket behind it.
 
We pulled a 15ft. Forrest City Do-all behind a 4040. ALL it wanted 6mph set shallow. It has spring teeth. Rolling cutter with grader blades then a heavy flexable harrow .pull it now with a.GX126 Kubota.
 
I pull a Kent Disc-o-vator with 5 bar harrow and like it. Great plains bought them and I think you can buy a similar one from them (and parts). From Kent, there were different models and the last ones were the best. I like mine and for the price you can't beat it. Mine went over all my ground last year, didn't even use the field cultivator once because of some weedy stuff that crept in too fast. I pull a 28' with 240 engine hp and no problem.
 
A Krause landsman does not pull to hard. We have a 23 footer and the 43 will pull it but gives it a work out.
 
Go with a Landoll. Along my road in a five mile stretch every farmer but one has a landoll for a total of eight of them.I have the small one and have never plugged it yet and it does a good job of leveling. There were a few Krause machines but the owners said they ridged the soil. There are few Deere's around as well. Tom
 
Unless your 4320 has the pump cranked and is breathing fire I wouldn't think it would want much more than 16' maybe 18'. We always pulled a late model 22' Kent Discovator with the 4640 fastest it would pull it is about 5 mph, maybe 6 on the good flat ground. We got a 4650 fwa last spring . The dyno sheet said 193. It pulls the same finisher 6-8 mph easy on most our ground except the tough clay hillsides.
