I'm not sure why folks worry about putting hrs on their tractor???
Personally, I wouldn't buy a tractor that I couldn't leave at pto speed for hours or even days at a time. I would do it with mine and not worry about it at all, after all, isn't that why you bought the tractor in the first place?? To be used when you need it most? How often does your tractor need to be left running for days at a time over it's life to worry about that??
Over the years, we have had some big storms and some of them have caused power outages. I can honestly say, I've never needed my tractor to run full time during an outage, so it is available for use during those down times.
During an major outage, either the rain is pouring down and I don't want to go out and "clean up" during that, or it's snow that caused the problem and there's no hurry clearing that out, as the roads aren't open anyway, so where am I going to go? We are the type of people who keep enough food and other supplies around here, so we don't have to run every day!
As for convenience, there's no doubt it's more work to have to go out and start a tractor than sit in the house in front of the TV, but I do not run my pto gen set unless it's an long term outage, I wouldn't want an auto start genset wasting fuel/money starting every time there's a little blip in the power either. We have LED lights scattered around the house and a couple LED lanterns too.
For long term power outage, which isn't often, it's no big deal to me to use my pto genset. Of course, some one else may be a lot more power Hungary than we are.
