Ok today was a bit crazy. So I have a b2710 with la402 loader. Curtis cab and rear tire chains on turf tires. I livd in vt. It was around 12 deg ferenhight when this happened. So was dumping a load of sawdust for beef barn out side and bickering it in to bin. Trailer dumped sawdust stayed in trailer it started to freeze. So was digging out with bucket and dump body in air had made a dozen trips in and out of barn then notice a stream of wet. Stoped immediately. Got out and the right of tractor rear shaft that wheel bolts to hydraulic fluid is streaming. Not good get down wipe clean with rag, slide the seal and what I assume is a bushing back in place, back together. Leak stops ran tractor for hr or so after checking and toping hydraulic fluid off. Little bit. Seamed fine. But question is y did that happen ? Is it need replacing? What holds that part In? What dose it in tale to change or am i going to damage something if i keep running it. I use the tractor like 20 hrs a week right now, plow truck is broke down so this is my snow plow, feeding cleaning firewood moving all around machine right now.. thanks in advance. Also sugaring season coming cant afford for this to be down durring sugaring.
