The Rhino SE7 requires a minimum PTO HP of 45.
Your New Holland TN 55 has a PTO HP of 42.
Usually you want even MORE HP than the minimum required for a rotary cutter. You have less than the minimum, so I would not recommend this combination.

He could go with the SE8 "pull type" and be ok as it has a minimum pto horsepower requirement of 30.

Although Gatorboy has a point about the recommended PTO HP "requirements", I ran a cutter the manufacturer recommended 20 (PTO) HP minimum. I used a 16.5 PTO HP tractor to operate it..other then having to take partial passes when it got really thick, I had no problems at all. This was a field that had grown for two or three years...the stuff was thick and as tall as the cowl (or higher in some places).
My current tractor, a Deere 790, has 24 HP @ the PTO...I'm running the same cutter and have no doubt this tractor could handle a 72" cutter if used with a modicum of common sense. The weight of the cutter would be more of an issue with my 790, then the "minumum" HP requirements.
So, I'd go for that 84" cutter...your 42 PTO HP will be more then adequate if you use common sense.

Personally I would not want to run something that I couldn't use 100 percent of the capacity 100 percent of the time. And the point of weight issues is a valid concern also, especially in rough and hilly terrain.

I know absolutely NOTHING about your tractor.... I know a little about that mower....
Here's what I DO know. I use a 7' Woods BB840 behind a 6500 lb (including ballast) Deere 2440 (60 PTO HP) That mower weighs enough to give my tractor a work-out....I do commercial mowing. When cutting HEAVY brush and weeds, it gives the 60 HP engine a work-out.
My opinion, for what it's worth.... You could handle 7' if you're just clipping pastures, or maintaining a field that gets mowed quite regularly. I'd say you wouldn't be too happy with the results in heavy weeds or grass. Weight-wise, I'd about bet you'de be disapointed....
All just opinion.... I have little "factual information" to base this on, OTHER than my experience with ANOTHER brand of tractor, as well as ANOTHER brand of 7' mower.

I'm also looking at the SE7 and SE6. for about 800 less and 1 ft less capacity you can get the SE6, which would likely be easier on your tractor. Mine could handle the SE7, but I think my pocketbook would like the SE6 better /forums/images/graemlins/smile.gif.
