Pulling empty recycle bin in my toy trailer, 37F, slushy road, locker switch engaged, one wheel on pavement, the other on packed slush, slight grade. Suddenly "click," and no drive. Cycled disengagement "wire," nothing. Cycled electric dash locker switch. Nothing. Next scene pulling machine with car up slight grade and into shelter. Grunt grunt, 800 lb beast. No attempt yet to diagnose. The tractor has never pushed snow and only used locker to evade mud holes. I am hoping (somehow, Murphy) that this is some "minor" linkage problem and not fatique/snap of axle shaft which would be a great disappointment. Please chime in with theory.....ha ha ha (always wait 5 sec after actuating locker switch)
Later. I reread my bloated thread and see a warning about a shear pin weakness on the locker engagement drive. RATS if I have to go in when I have babied this thing. (Probably due to OCD gear oil change when not really necessary)
3/13/23 I am too wimpy to get under the Husqy for initial look (37F, no heat). Prolonged search does not reveal any obvious, or named " shear pins" in rebuild kits or in several (long) youtube K66 rebuild videos. Perhaps something upstream. Any ideas?
