I dunno, I have a neighbor who lost her husband, so I cleared the brush off their leachfield as a favor, her husband was good to my family. My kids use it at their new house. We got the tractor as an extension,of our business, and a way for wife to make money. For actual customers we charge. Maintence, fuel, insurance, wear and tear and the monthly payment can add up. If you can personally afford to do favors,I say go for it. I have bartered in the past, but had bad experiences or poor work done in return. I have had friends who wouldn't respond when I needed something, but most friends are dependable. plowking
