My Gravely that I had before the 4010 had a 4' snow blade, a huge thing for such a small tractor. It worked fine.
For a bigger tractor (e.g. 2305 is about 3 to 4 times heavier than a Gravely), you'd want a snow blade with a trip mechanism. The Gravely's didn't have this. If it hit anything, the tractor would fairly easily shift to the side.
If you get heavy, especially heavy wet, snow, you'll may need some chains. The Gravely needed them until I put dual wheels on it. They had enough traction for most snow conditions.
On my 4010, I use the
FEL and a back blade. This rig works for snow falls up to around 6" or so. Beyond that, the back blade may be a bit short (in height). Don't really know because we haven't had too much snow since I've had the 4010. The
FEL can easily handle deep snow but is very slow because you keep having to turn and dump.
