I 've searched and have not acquired the information I am looking for. I'm confused on what V plow would be best suited for my snowplowing needs. I push half driveways and half commercials lots under 2 acres. The questions I'm concerned about is which V-plow will back drag the driveways the best. I've been told that the Hiniker V hydraulic cyclinder does not hold straight when back dragging because the cyclinder does not lock. On the other hand, Boss has an optional $275.00 Smart-Lock Cyclinder that claims it locks when back dragging! Has anyone purchased the Smartlock and how does it perform on back drags? Another question is under these conditions ---Live in Indiana -maybe 4 good snows a year tops- I would be putting this plow on a 99 F-350 4X4 (single rear wheel) truck; should I go with an 8ft or 9ft V -plow given this information. I currently have an 8 ft straight blade on another truck now. Its seems in all the threads that have been posted, that majority favor the efficiency of the V-plow and how well it works. But will it work for me? By the way, I have listed these 3 V plows since they are the only dealers within 50 miles of home. Thanks for any feed back.
