I agree with sagebrush and think the BIO-90 is the best option when it comes to the four available chippers. The problem with these small chippers is the fact that they have such small throats. Sure, it'll chip 3" for the BIO-100 and 3.5" for the BIO-150. But, unless you're chipping very straight, limbless branches, you can't physically GET the material into the chipper. I took on a job with my BIO-100 a couple years ago, cutting and chipping up some buckthorn. It was brutal. I ended up taking three times as long as I thought I would. Every limb had to be cut at any hard bend, any branches over 1 inch need to be trimmed - the prep work took up an immense amount of time. Once I prepped the material, I had to feed every bit in, one at a time. The hopper doesn't allow you to drop a stick in and let it self-feed. I sold the BIO-100 this past spring for $500 and I repeatedly warned the buyer of my issues with it. Frankly, the BIO-100 is the oldest design. You'll notice the other three units have a very different, better design.
With the BIO-90, there is very little need for prep time - if it's under 2.5 inches, just toss it in. The throat is 8 inches at it's bottom and is so big you can just drop the branches in and grab the next one - no manual feeding. You need to be sensible about it, though. You can definitely push too much in or put too big of branches in. Its limit is 2.5 inches. It also calls for 13 hp, but I think Joel is being too cautious with it. 11 hp is fine if you don't jam the material in too fast. It also will not take any wet material, green leaves on just-cut branches are fine, but any garden waste won't go through.
I think the best lot clearing combo would be a Berta Flail mower and a Caravaggi BIO-90 on either a Grillo 107d or a BCS 853. The flail mower will shred on-site all green vegetation (including your leaves in the fall), and the chipper will chip any woody material under 2.5 inches. Anything over 2.5 inches gets lumped up and used to heat the house or for family campfires
