looking for some help on a problem in this cold weather, I have a LX 865 been parked for a few weeks, in below freezing temps went to use it today and left side drive works, but right side doesn't budge an inch> I left motor run a bit hoping maybe heat from it would thaw anything frozen up< after 15 minutes, NO go so took a torpedo heater and left that run about a half hr, and, she was back to working I am new to these machines and never worked on one really,. and NO great MR fix it This past Aug, I had a local NH dealer, change ALL fluids as if doing a 500 hr service, which was supposed to have included drive fluids but at this point I am thinking they didn;'t do what they charged me for?/ SO question is, HOW do I solve this problem, what and where do I have to drain fluids from I don't have a shop on site and don't have away to move machine right now, its parked under a small 3 sided building with a gravel floor, that just fits the machine in it with NOT much room on either side? I am sure if I need to use again, I can just heat up again as I did, but I prefer a better fix if its something simple I can do? can anyone explain what all I need to do?? Machine ran just fine for about an hr after I got it free'd up too>
