Stormtruck2,
I really like my King Kutter II 3-point tiller. It's all gear driven, and it's one tough beast. I think you'd be very happy with it.
There's no sure way of knowing how many hours I've put on the tiller, but I'm pretty sure it's well over 200 hours so far. The people driving by while I'm working will usually stop to ask if I'm available to do custom work for them. I've tilled up a lot of gardens in town.
The King Kutter II tiller can be found at most any Tractor Supply store, but there are many other dealers that handle that line, as well.
Figure about 5 horses per foot when looking at tillers. If the ground is mostly hard clay, figure between 6 and 7 horses per foot. If you've got 35 horses at the PTO, you should be able to run a tiller 6 feet wide without any problems at all. That will also allow you to cover your tire tracks.
Hydrostatic drive is very valuable when tilling. If your tractor is a gear model, you might want to see if your tractor will go slow enough to handle the 6 foot tiller. If not, you may need to go down to the 5 foot model.
Hope that helps.
Joel ....

My 4600 is a HST so the hydro is covered. The ing cut is gear driven, compared to a hydrolic or what other drive types are there? Our soil out here is heavy black clay so it can be hard as concrete.Thanks

Storm;
My tiller is a Land Pride 1558 58 inch model for the 4310, it's been a good machine. Most all of my three point equipment is Land Pride, not the cheapest but top drawer quality. The other types of drive are chain and Deere built a hydraulic drive for their lawn tractors at one time. Mine is a chain driven, the chain is enclosed in an oil bath situation. I don't think there is enough difference between gear and chain to even talk about so long as both are properly maintained.
Land pride also builds a reverse rotation model. I've never saw one used, their claim is that they will never "Float" out of the ground because they are always pulling down being they run backward. I've never had that problem so far. I've always wondered if the reverse rotation models would work better in trashy conditions in that they would throw the trash up and over the knives rather than wrap like a front rotation machime will??
If you have operated any tiller you already know that rocks and trash are not their best friend so be sure you get one with a slip clutch in the PTO drive. Shear bolt drives are also used and acomplish the same thing as a slip clutch except you have to replace the shear bolt after each encounteer with sometning.
Mine has a sideshift feature that allows you to move the tiler to one side of the hitch to cover the wheel track on that side if the tiller is narrower than the tractor. That feature will allow you to use a narrower tiller instead of buying a more expensive machine to match the width of your tractor. Mine does cover both wheel tracks but on your tractor it may not.
Nothing wrong with finding a used one, as most won't have enough hours to even talk about. ....

Stormtruck2,
Hard clay won't be a problem at all. Just go slow.
If you find that the tractor or tiller is having a hard time of it, just move over into the previously tilled area a couple of feet (overlap) so that you aren't breaking up as much packed soil with each new pass. Your first trip down will be the hardest for you.
You could also adjust the skids for a shallow cut on the first pass, then adjust them for a deeper cut on the following passes.
The King Kutter II tiller is fairly heavy. I've never had a problem with it lifting out of the ground as it breaks up sod. My 5 foot model weighs 690 pounds. The 6' tiller weighs 780 pounds.
The King Kutter II tiller has a very heavy, adjustable rear gate. If you close it down you'll get a very fine soil. If you open it a couple of chain links, you'll find that you'll be able to travel a bit faster, but the finished soil won't be ground up quite as fine.
The King Kutter tiller comes with the PTO shaft and the adjustable slip clutch. The PTO shaft may have to be cut to length to fit your tractor. It's not difficult to do, but it's important that you do it correctly.
Be prepared to add oil to the drive end on any tiller you buy. The drive housing will be drained when you receive the tiller. You'll also need to grease the end bearings, PTO shaft, and U-joints. Setting the cutting depth is done by adjusting the outside skids. You'll need a couple of wrenches.
