The B7100 is a little light on the PTO HP necessary to run most chippers. Most want 18 HP or more. There are some light duty ones that may work if you go slow and don't put anything very large in. I have noticed reciently that some of the 4 blade models cut with 2 of the blades at the the OD of the flywheel and 2 of the blades closer to the ID. This means that each blade is only cutting half the wood on each pass and may require less HP but would also be slower.
I posted the following last year after I bought a chipper, maybe it will be of some help.

Last week I purchased a PTO woodchipper for use with my B2400. I had been looking at different brands for a couple of years. I decided on the Danuser model 18P. This is a 4 inch chipper with power feed. Even though it is rated to take 4 inch diameter wood, the actual infeed opening is 6 inches square. This aids in fitting branches through the opening without getting jammed. The power feed is gear driven off the chipper power shaft and feeds at 55 feet per minute. Many other brands have hydraulic power feed. The gear drive does not allow the feed to be reversed in the event of a jam, however it does not require a hydraulic connection to the tractor.
The chipper is built of heavy gage steel with hefty bearings and shafts. The 106 pound flywheel turns at 1280 RPM with 540 RPM PTO speed and there are 2 cutting knives. Most of the other brands have the flywheel turn at 540 RPM. A slower flywheel stores much less energy than a faster turning one. The higher speed also results in more cuts per minute even though some of the other brands have 3 or 4 blades. The speed increase is accomplished with belt drive. These pulleys have 8 belts side by side to handle the torque load. The belts act as a mechanical fuse if things get jammed, preventing damage to either the chipper or the tractor.
The chipper is rated for 18 to 45 HP. My B2400 is on the bottom end of this rating producing 18 PTO HP. I did succeed in stalling the tractor on a piece of 3 ½ inch dry maple. The tractor stalled after about 7 feet and yes the belts did squeal when this happened. I guess I should have disengaged the power feed. Interesting enough the tractor RPM never even never dropped on anything else I chipped all weekend including some 4 inch oak.
The chipper has a built in fan on the back of the flywheel that lifts the chips up and discharges them out a chute. I built a plywood extension and top for my trailer and shoot the chips into it.
I am satisfied with the quality of construction and ease of operation. The power feed is great. I decided on the power feed because it will pull small branches and vines as well as the large stuff right into the chipper. It eliminates kickbacks which can happen with the last foot or so of the branch without power feed. It is also rated as quieter than many other chippers.
I paid $3475 for the 18P, the model without power feed (18G) was $1000 less but is being discontinued. The first dealer raised the price $600. since I priced it with him last fall. I contacted the manufacturer and was told the list price had increased $100 during that time. I found another dealer that sold it to me for $75 more than I was quoted last fall.
