I have a 2305 and a had to use it with a 84" Woods rear grader balde to remove about 6" of sudden snowfall off my 300' crushed stone drive. I did not have the time or light to remove my BH448 off the 4720, so thought I'd give the the little guy a chance. That Woods HBL84 with shoes weighs probably 600+lbs and the 2305 shined uphill/dowhill pushing snow. It only had approx. 8" ground clearance with the blade in full upright position and would only work pushing snow backwards with blade curved backwards, but it proved itself. Here's a pic...I find the 2305 to be a great little tractor. If it is a measuring stick for the 2320 and 2520, then I fully endorse moving up...as doing so can only bring you closer to realizing greater performance. Ground clearance and 3ph control are the weak points of the 2305, but still a great machine...no regrets.
