Bought a holdover Ariens 28'' 420cc pro model this year to replace my 74'' model Ariens with a 7Hp Tecumsuh. During this latest big dump I brought it out and I wasn't overly impressed. I felt like the machine kinda had to many features lol. One thing I'm not big on is the safety auger engage/disengage lever. I'm used to the old machine which was always turning once you enaged the lever. I feel like I could have been done faster with the old machine! The other thing I was kinda not impressed with was that I figured the 15hp motor would absolutely power through the snowbank the plows left for me. When I started in, I put it in a low gear and began but to my suprise it bogged a bit. Now granted the snow banks are dense from the plows but I would have thought it would obliterated it with no bogging in the lowest gear! My old machine would bogged some but it was half the power! I don't know but I'm wondering if I should have kept my 38 year old beast!
