Yes, it was dumb. I started to mow with my L3400 and I got stuck. I forgot where the front wheel drive level was. The tractor started to roll backwards and I panicked a bit. (I'm an older woman alone.) So I turned off the tractor, forgetting to disengage the PTO. Now since the PTO is engaged, I can't turn the tractor on to left the implement or do anything. Is there a way out of this mess?
