I have used a 10 ft wide double roller cultipacker behind my old 1999 honda 400 foreman atv for 15+ yrs and atv still runs perfectly!
so I doubt you will wear out a atv using a packer larger than 7 ft IF its the right atv for the task, belt drive smaller CC atv's, OK I can see it maybe hurting one of these
, but a larger sized atv or a honda gear drive ATv, I doubt you will hurt it at all!, unless your in super hilly area's, or your trying to pull it way too fast in too high a gear! LOW range and good to go for yrs! IMO! and the proof to back it up 15+ yrs and still running like new!(averaged about 10 acres a yr too of plots and packing with it!, spraying and adding fertilizer too and even pulling atv sized disc's and harrows)
Now as for adding transport wheels, I think this would come down to the design of the packer itself and if its feasible to do so, as GOOD heavy packers at 7 ft wide might eb way too heavy for the average human to flip over, my 10 fter weight well over 1200 lbs! even if I lost the second roller, that would still be in the 600+ lb range! more than I woudl wanat to try to flip over alone! a 7 ft would I guess be about 400+ lbs? still a handful
maybe you could add some drop down wheels with a screw jack like set up? one to each side and weld them on(axles on ends) then you can simply screw them up or down to run down roads
as I could see why wheels would be helpful for many places, as cast iron packer wheels are NOT made to be pulled fast and can be damaged if done so!
I never pull mine more than maybe 7-8 mph! unless on fresh soft soil or grass without any rocks, which is rare here LOL
