If you live in an ag area there should be a number of equipment dealers that rent equipment. Even large farms rent equipment or outsource certain operations because the capital investment does not pay off if you only need to use the machine once or so a year, but the activity is essential. I think it is often better to ask a neighbor farmer if you can pay him/her to come in and do something for you as that way they feel you value them and also you won't break their equipment. Once you own equipment you will find things break. Generally equipment from a rental outfit will be ready to go to work and most agreements cover who pays for wear parts such as cutting edges, etc. My own experience is the large rancher/farmer in my area has been very generous to help. I buy some hay from them and I have got to know them. I ask questions about when do you do certain things like drag harrow your field. The next thing you know they are offering you to use their harrow if you want. I find that even the big guys with thousand of acres want to be good neighbors and also they like to see other people that love the land and want to be productive.
