The purpose of the annual bulb harvest in "Mrs. Frisby and the Rats of NIMH" is for the rats to collect bulbs from the farmer's garden to use as a source of food during the winter months when their normal food supply is scarce. This harvest ensures that the rats have enough sustenance to survive during the colder season.
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.
