Interesting information :-) Might help clear up a bit of a mystery, by finding out where son purchased, rototiller's model, make, any information that could be tracked down.
I must admit that what's got me puzzled, is tractor's ground speed issue. 8N (& NAAs) slowest speed is reportedly too fast for allowing tiller's rototines to do a deep, thorough job of it.
Conceivably, one could upgear PTO speed on rototiller and that would make tines turn more quickly at tractor's lower forward speed, and that would take care of the RPMs needed, but what about necessary power?
Gear tractor is in and throttle setting both affects tractor's speed, but it also affects PTO speed on 8N (no live hydraulics, but there is a "How To" article to provide live hydraulics: http://www.ntractorclub.com/howtos/pdfs/How-To-Provide-Live-Hydraulics2.pdf)
At lower engine speeds, and lowest gear, 8N can be made to move slowly forward, at the sacrifice of power and torque (which comes with higher RPMs). Reportedly, even in the slowest gear available, 8N is moving faster than the one to 1 and 1/2 mile per hour "creep" best served for rototilling.
With such opposing information: 1) you having personal experience showing NAA can effectively run this particular rototiller in those specific conditions, and 2) opposing information from folks who couldn't get their tillers to work satisfactorily?
Definitely a conundrum! I'll be most curious indeed, finding out how this "mystery" plays out :-) Where's Jessica Fletcher When you need her? (Don't think I'd want to live in Cabot Cove; Maine: that place's got to have the highest per capita murder rate in the world! ;-p ...Now Jessica's gone & disappeared and we can't find her?!! No way I'm going to Cabot Cove looking for her, got enough of a mystery here to solve. ;-) lol)
Typically what's reported: needing previously worked soil, soil type sandy or otherwise conducive towards rototilling, low depth of tilling cut per pass, multiple passes required for adequate depth and soil texturing.
