My 4010, which is the same weight as your 2305 but geared differently because of the way the wheel shafts go straight out for greater clearance vs. down like yours, sounds rougher in
4wd on paved surfaces. This is because the front wheels are designed to go slightly faster than the rears. This is tougher on paved surfaces.
On pavement with snow, you won't notice any problem. The front wheels can overslip a little bit on the more slippery surface.
