Regardless of how you arranged things last year with your old neighbors, its a whole new ballgame now. Without knowing all the specifics, I gather that you and your new neighbors share responsibility for maintaining a common road/driveway thats between your houses. Paying and sharing the costs for someone to come in and do it would be ridiculous since you have the equipment to do it yourself. On the otherhand, you don't like feeling that your new neighbors are taking advantage of your generosity. You also stated that they may not be able to afford an outside contractor, but this may not always be the case in years to come. I imagine that being new to the neighborood, they came out to the country and bought the biggest spread they could afford, ill prepared for the environment and ignorant of the type of equipment they would need to maintain their property. I see this happen all the time...I was even a country newb myself once upon a time. No way could I afford a CUT in those days when I first moved out to the country, though I bought an 8N the second year. Fortunately for me, I had an understanding neighbor that would come over and plow my 200' driveway after seeing (and perhaps laughing at) me on my little garden tractor trying to clear snow. I did everything I could to repay his kindness...cases of his favorite adult beverage, offers of help when I'd see him outside working on his equipment, and let him pull hay off of about 5 acres of the 10 that I had at the time. As it happens, he worked days, and I worked afternoons (though I'm off all summer /forums/images/graemlins/grin.gif). In the winter time though, once I got my own tractor, if it snowed during the early morning hours, I'd do his drive as well...and if it snowed at night while I was at work, he'd do my drive. We went on to have a great friendship, and I still keep in touch with my first country neighbor to this day...15 years later.
My point is this. Be a good neighbor, and regardless of the ultimate outcome, your gonna feel good about yourself. Let your new neighbor know that there are expenses involved in the upkeep and don't expect to be paid as if you were in the business. Ask for an occasional tank of diesel fuel, or a case of the beverage of your choice, or perhaps a home made pie every once in a while. After a few years, when they catch up with the logistics of country living, I'm sure they'll be right there to help pitch in, as I was....and then ask if its ok that their kids call you 'Uncle Chris". /forums/images/graemlins/grin.gif
