I think those splitters are meant for towing around the yard and in and out of the woods, not down the road in any significant capacity. The couple times I've had to move one, I just grab a buddy and heft it into the bed of my pickup, then ratchet strap it down.
That may be true for some of them, but my Huskee 22-ton manual specifies the splitter for on-road towing up to 45 mph maximum speed. They have a whole section on road towing instructions and precautions, if I recall. I only towed it on the road twice, myself, but it did fine.
Similarly, the Iron and Oak splitters (same basic chassis) rented by stores and rental companies all over this country are towed on a daily basis. If stores are allowing customers to tow them, or more importantly their business insurers are permitting that rental, then it must be specified for such by the manufacturer.
That said, if I were to tow it again today, I'd throw it on my trailer. I hated towing something that was too small to see in my mirrors, or that I couldn't back up if I needed to.
