The PT-425 has four hydraulic motors on the wheels, and I think they are plumbed in two circuits, so it's a four wheel drive, but there is a differential effect that - I'm just not exactly sure how it works. I had traction that flat out surprised me in our big snow this year, and I could "crab" the PT with the articulated steering if I got in a spot where all four wheels spun.
On the G152, I had to rebuild the front PTO. There is nothing hooked up to it in that pic, but there is an electric winch on the front. I bought the tractor with a belly mower, which works pretty well if I adjust all of the mounts regularly. It has a small brush hog (3pt) which it struggles to power so I have only used it a few times. A Bolens front mount snow caster, which I tried this winter but I struggled with the cable lifts and I am not sure I get the rpm out of the G152 to actually launch snow out of the caster. Maybe the blade needs a weld on the screw where it meets the shoot to close the gap up some. Will have to figure that out this summer. Also have a snow/dirt blade on the front. I took a tip from the PT blade and put a horse mat rubber lip on it. I garbage picked a Deere 3 PT finish mower, but I think it was designed for much higher RPM as after a refurb, I can't really get it to actually cut grass- another project to figure out. The previous owner put a HF winch on the front to raise and lower the blade, but I think I have the cables from the 3 PT almost figured out, because the winch has a lot of lag so it's hard to be accurate. I think I need weight in the rear, but I'm not sure how much . .. I couldn't drive around in the snow with the caster mounted, which is probably a good thing since I didn't get the caster working so well anyway yet. It's really a good time figuring all of this out while I go, and the G is such a forgiving tractor to learn on it seems.
