Hey all! Today I was pushing snowbanks back & my 2320 made a screeching noise followed by clicks & stopped moving. It was in low range. Under no strain It'll move itself. High range still works fine. It's a 2010 year model & only has 103hrs on it. It's had its 50 hr service. Any ideas? I'm mechanically inclined but wanted to ask first; don't want to make it worse! Thanks in advance.
