It has held up very well. I've had it now for 16 years and last year I replaced the front tires that were about bare. My property is close to ¾ acres with a large u-shaped drive of an equivalent length of 260 feet. No major slope for the driveway. The backyard (towards the community lake has a 16 foot rise from the lake to the front of the house. This is no problem for the LX178 at all. My lot is on a cuildesaq (wrong spelling I know) with a lot of good neighbors so besides my driveway I clear snow from 4 to 6 others as well. A couple of them have quite steep drives. (I put on the pants of a rain suit so I don't get wet from melting snow.) I have to use chains. It would help to have added weight as I only weigh about 170#. I don't have nearly as much snowfall as you do so my extra driveway clearance probably makes up for the amount of your snowfall. I do wear out the skids fairly frequently (every two years or so). My biggest difficulty is breaking the drive belt for the snow blower and for whatever reason the auger shear pin has never sheared. Overall I don't see the snow blower putting any greater effort/stress on the tractor than grass cutting. Mine is a water cooled engine and the engine continues to run just fine.
