I would say it depends on how often you use it. It's 225lb's sitting on the front end when installed so I would imagine your springs would sag a bit if they weren't upgraded.
I'm not sure of your exact situation but it looks like the smallest size blade plus the mounts will cost you $2k USD w/o tax and free shipping. Since you've plowed before I won't go into specifics but if you set up the blade to provide the least amount of resistance and used it at low speeds in 1st or 2nd in 4wd I think the Pathy would hold up just fine for the occasional plowing. Certainly cheaper to plow your own drive than have a service.
Not sure how things are up in your neck of the woods but around here I could find a pickup with a plow for $2.5k or less. If you have that opportunity I'd push for that route as plow vehicles take a beating. Just keep it on the property and don't license or insure it. Of course if that's legal in your area that is.
Save the wear and tear on the pathy.
