What does custom farming involve?

Custom farming typically refers to a type of agricultural arrangement where a farmer uses their machinery and services to perform farming tasks on someone else's land for a fee. This process often includes activities such as planting, harvesting, or maintaining crops on the property of another farmer or landowner.

In this case, the correct answer highlights the aspect of using the insured's farm machinery away from their own premises, which is a defining characteristic of custom farming. This arrangement allows a farmer to utilize their equipment and expertise to help others manage their agricultural needs while receiving compensation for their services. Custom farming is beneficial for both parties: the service provider can generate income without having to own or lease additional land, while the landowner benefits from professional farming practices.

The other options do not accurately capture the essence of custom farming. Using insured's machinery for personal tasks, farming for family members without charge, or planting for neighbors in exchange for goods doesn't involve professional agricultural service for compensation, which is a fundamental aspect of custom farming practices.
