I really dunno, I have not seen my brother do anything with his 700 Prowler any faster than I can get done ith my 450i, I'm sure he can go faster and maybe pull more weight, but I haven't seen him do it, in fact, I haven't seen him use his Prowler for anything close to the capabilities of even the 450i, he has other equipment (log skidder, excavator, tractor, dump truck, even an old Oshkosh) that he uses for heavy lifting
