One other purpose for which Farmer Fitzgibbon uses his tractor in "Mrs. Frisby and the Rats of NIMH" is for harvesting the field. The tractor is used to prepare the land for planting crops and then later for collecting the ripe crops during harvest season.
There are several different ways the word "proceeds" can be used. Proceeds are the value of land, goods or investments when converted into money or something else of value. Proceeds indicates a change in form of an asset. Proceeds can be the amount of money received from a sale. A more interesting example is provided in Black's Law Dictionary: If a farmer borrows money from a bank to plant wheat, giving the bank a security interest in the harvest, the harvested wheat is considered collateral. Alternatively, if the farmer exchanges some of the harvested wheat for a tractor, the tractor becomes the proceeds of the wheat.

What once took days in the past, is achieved in hours using a tractor and modern equipment.

Generally, if you will be driving the tractor on private land, then when the adults in your life can make the decision as to when you are old enough to safely drive the tractor.
That depends on the size of the tractor trailers (they come in different sizes/models). and how many roadways you will need to get them on/off the land.
