I'm not familiar with the 2 that you link, but we've got quite a few yrs experience w/the Hopper Walker products. Had them on 10" swing arounds for years, then added 13" augers this year. Updated to the newest Hopper Walkers & they work fine. Making sure you have enough ground clearance under the swing around is a necessity. We also foam-fill all the little tires. Seems like always the little tires that come with swing-around, plus the Hopper Walker tires would go flat occasionally. If you try to operate the Hopper Walker w/a low or flat tire, you'll roll the tire off the rim. Foam filling ended the problem...forever.

As another poster said, just sit in the tractor cab & operate the truck traps w/the electric trap control & move the hopper walker w/it's remote & life is better, quieter, & cleaner.
