The Tractor

The tractor is the primary instrument of dispossession in The Grapes of Wrath, a machine that transforms the agrarian landscape and the lives of the people who work it. It is not merely a piece of farm equipment but a symbol of the industrial, corporate power that severs the bond between humans and the land, replacing families with efficiency and profit. The tractor's arrival signals the end of a way of life, and its operation is depicted as a kind of violence—a surgical, unfeeling process that leaves human wreckage in its wake.

The Machine and the Monster

The tractor is introduced in Chapter 5 as the tool of the bank and the large landowners. It is described as a "monster" that "the bank—the monster has to have profits all the time." The men who drive these tractors are not farmers but operators, often local men who have been turned against their own people. One such driver, Willy Feeley, is a former neighbor who now drives the "cat" that plows under the Joads' home. The tractor itself is a "snub-nosed monster, raising the dust and sticking its snouts into it, straight down the country, across the country, through fences, through dooryards, in and out of gullies in straight lines." It ignores the boundaries of human life—hills, gulches, water courses, fences, and houses—cutting a straight, indifferent line across the land. The driver is dehumanized, "gloved, goggled, rubber dust mask over nose and mouth, he was a part of the monster, a robot in the seat." He cannot see the land as it is, cannot feel its warmth or power; he is a mere extension of the machine, which is itself an extension of the bank's will.

The Destruction of the Joad Home

The tractor's most devastating personal impact comes when it destroys the Joad family home. Grampa Joad stands out with a rifle and shoots the headlights off the machine, but the tractor comes on anyway. Willy Feeley, the driver, knows Grampa won't kill him, so he simply drives the tractor through the house, "bumped the hell outa the house" and "give her a shake like a dog shakes a rat." This act of mechanical violence breaks something in old Tom Joad; "it took somepin outa Tom. Kinda got into 'im. He ain't been the same ever since." The tractor does not just destroy a building; it destroys a man's spirit and his connection to the place where he was born and raised. The house is left "mashed at one corner" and "pushed off its foundations so that it slumped at an angle," a physical testament to the machine's power to unmake a home.

The Tractor as a Symbol of Systemic Change

Beyond its immediate destructive power, the tractor represents the systemic transformation of agriculture from a human-scale enterprise to an industrial one. The owner men explain to the tenants that "one man on a tractor can take the place of twelve or fourteen families." The machine makes the tenant system obsolete, not because the land is poor, but because the bank demands profits that only mechanization can provide. The tractor is the instrument of this new logic, and its operation is described in terms of rape and surgery: "Behind the tractor rolled the shining disks, cutting the earth with blades—not plowing but surgery... and behind the harrows, the long seeders—twelve curved iron penes erected in the foundry, orgasms set by gears, raping methodically, raping without passion." This language strips the act of farming of any human connection, presenting it as a cold, mechanical, and ultimately violent process. The land itself suffers under this regime: "The land bore under iron, and under iron gradually died; for it was not loved or hated, it had no prayers or curses."

The Tractor and the Exodus

The tractor is the immediate cause of the Joads' journey west. It is the force that "tractored all the tenants off a the lan'," as Muley Graves puts it. The machine is the physical embodiment of the economic pressures that drive families from their homes and onto Highway 66, the "mother road" of flight. The tractor's work is the catalyst for the entire narrative: the dust, the drought, and the bank's demand for profit all converge in the tractor's blade, which cuts through the dooryard and through the lives of the people who lived there. The tractor is not just a machine; it is the agent of a new social order, one in which the land is no longer a home but a commodity, and the people who work it are no longer farmers but migrants.
