Had a similar thing happen this summer. Good friend had some unexpected family issues come up. Called his wife and said I was headed for their field and would be cutting before the day was out. The move to his field required most of the day to shuffle equipment. Her response was what about my personal crops. Told her I was not worried about it and she need not worry either, God would provide. No one else showed up which was understandable as I did not put out the word, however when I was back on mine a good neighbor showed up and wanted to help me which I did accept. Ended up we helped each other for the rest of the summer. The friend I had helped was able to come with a truck latter in harvest and help also. Just do the right thing even if you do not see how it will work out and I firmly believe God will put it all together for you. You just need to make that first step in faith.
