JD440IC plowing snow? Hey, I've got one of those...

Pretty basic video; I shot it myself by sticking my phone to a rock with some snow. You can't tell from the camera angle, but I've got the blade angled to discharge left. When the snowpiles get big enough, you can see the front end of the machine is forced to the right because of the blade angle.
This machine is brand-new to me. It was running, barely, when it arrived. So far I've done nothing but clean out the entire fuel system, overhaul the carb, and change the engine oil. Still looking forward to tearing into the starter and cables (it cranks real slow on a brand-new battery), the generator (it's not charging), ignition timing, valve adjustment, some new grease fittings...
AND, some attention to the clutches and brakes. Note in the video that it squeaks whenever I brake the right track. Something's wrong on the right side. I've popped the covers, and not liking what I see on the right. The right lever travels a long long way before the throwout bearing contacts the fingers. Compared to the left (which seems to work normally as far as I can tell) the fingers on the right are a LOT farther away from the bearing. Kind of like they're stuck down (but the clutch doesn't slip). Also, I can see some of the brake band when I look down to the bottom of the right housing, like it's slipped inboard. However, on both sides, the clutches clutch and the brakes brake, and it transmits power just fine to both tracks as you can see in the video. Not sure what's going on with that right side.
