Come along for a ride as I plow one of our neighbor's driveways. This snow was light and didn't give me any trouble (aside from the front end not gripping the hard pack)
I too run a X758 with the 54-inch front plow blade. No side extensions on the blade though. I've got the rear weight set up with six 42lb suitcase weights and chains on the rear tires. Turf tires. Are you allowing your blade to "float" when you plow? Also, my area is all gravel, so the blade shoes (upgraded to the round ones) are set to keep the poly edge about three inches off the ground. I'm fine with hard pack forming and the only problem I've run into is with deep/wet snow which is a ton of weight to easily move. Just my two cents. Thanks for a great video!
