I'm down near Middleburg. Our "official" total was 39". I have an 1845, 425 and Kubota
L3901. The 1845 needs some maintenance (wheel circuit filtered due to pump work) and my 425 is out of service due to a blown motor and my decision to replace with a 35HP Subaru.
So, at home, we used my neighbor's 425. This is the tractor I originally purchased about 15 years ago and sold to him when I got the 1845. The 425 did an amazing job. At my dad's house, 1.5 miles away, I used my 3901. Frankly, the 425 was much faster. It's so quick to forward and reverse. Plus, the articulation allows you to dump the snow off to the side much easier than the 3901.
Comparing all three tractors, I'd say the 425 is easily my favorite, given the capabilities and cost. Although I only have 6 hours on the 3901, I'm not that impressed. Easy to get the tractor stuck or in a "scary" predicament. If you need to pull a plow or large tiller, which I do, then it's the best option. For everything else, the PT is much better in my opinion. I'll give a more detailed review once I get more seat time with the 3901.
BTW, we should consider a PT get together for the NOVA owners.
