¹⁵ For example, in 1860 Manny listed the f.o.b. cash price as $135 or terms of $50 cash (which is assumed to be paid on July 1), $50 on November 1 and $45 on January 1. These terms imply an interest rate of 29 percent. The Northwestern Farmer, V (June 1860), p. 238Google Scholar.

¹⁶ This is the figure cited in Hutchinson, Harvest, p. 74. We do not know how it was calculated, and the true rate may have been substantially higher.

¹⁷ Robert Ankli has convincingly raised such reservations about the wage rate and the labor saving (or productivity) or the machine. See Robert Ankli, “The Coming of the Reaper,” unpublished manuscript, Department of Economics, University of Guelph. Ankli has independently developed many of the ideas explored in this paper.

¹⁸ It is difficult to make precise statements of these revised thresholds since using the higher interest rate requires a reduction in the initial price. Since the prices used by David included an unknown proportion of both cash and credit sales, it is impossible to determine how much of an adjustment is needed. In any case, the threshold calculations are not very sensitive to small changes in machine prices.

¹⁹ There are numerous accounts suggesting this latter line of causality. For example, “They [mowers and reapers] have placed the farmer above the contingency of finding extra hands for securing his crops at a critical juncture, and on this account can extend his breadth of sowing with the confidence of being able to secure what he raises.” Thomas, J. J., “Farm Implements and Machinery,” in Report of the Commissioner of Agriculture for the Year 1862 (Washington, D.C.: G.P.O., 1863), p. 421Google Scholar; see also Hutchinson, Harvest, p. 76.

²⁵ The following discussion is based on data found in McCormick Company ledgers entitled “Reaper Sales,” for the years 1854, 1858, 1859, the McCormick Collection in the Wisconsin State Historical Society Library. A random sample shows that 24 percent in 1854 and 23 percent in 1859 of the reapers were jointly purchased. Cases where one of the individuals was identified as a financial backer securing the note of the other were tabulated as single rather than joint purchases.

³² The following examples represent only a small sampling of the statements found in advertisements and catalogues. An 1849 McCormick advertisement states: “Many farmers who have purchased one have earned its cost in one year in harvesting for their neighbors …,” The Wisconsin Farmer and Northwestern Cultivator, I (June 1, 1849), 144bGoogle Scholar. A similar claim is found in an advertisement reproduced in Hutchinson, Seed, opposite p. 330. An 1853 Ketchum advertisement quotes D. W. Schoonmaker of Seneca, New York: “I go round mowing; there has not been a day since I commenced mowing but I have from five to ten persons after me to mow. I have mowed in four towns …,” Ruggles, Nourse, Mason, & Co.: Catalog for 1853 (Worcester, Mass., 1853), p. 80Google Scholar. In an 1861 Manny circular Whiting, R.

Bidwell and Falconer cite 62 1/2 cents per acre as the cost of hiring a mower in 1858.

Within these pages are also several related county society reports on mowers.

Although this paper only touches on British sources there is at least some evidence of similar sharing behavior there. “A considerable number of these machines [reapers] have been worked on large farms, their price and bulk. rendering them comparatively inapplicable to smaller farms. This objection is, however, obviated … by persons letting them out to hire, the farmer supplying the horses to work the machines, and the owner sending a man to attend to it whilst working. On some estates the landlords have purchased them, to afford their tenantry an opportunity of hiring.” Journal of the Royal Agricultural Society, XX (1861), 127Google Scholar.

³⁵ If individual fanners in fact faced an upward sloping supply curve for labor then we must abandon the assumption that there were no diseconomies of scale to harvesting by cradle.

⁴⁴ Ketchum, the first producer to specialize in mowers, sold nine machines in 1849. The estimate of mower sales is based on figures found in Hutchinson and in company circulars and advertisements. These data indicate about 20,000 mowers were sold between 1850 and 1858.

⁴⁸ Hutchinson, Harvest, p. 393. David apparently errs in claiming that “McCormick did not manufacture a self-rake model until the introduction of the ‘Advance’ in the post Civil War period,” for Hutchinson notes that McCormick made his first self-rakers in 1861 and by 1864 two-thirds of his entire output were self-rakers.

Danhof asserts that “The need for several teams militated against the machine in the eyes of countless farmers who possessed only one team, or perhaps a lone horse.” See Danhof, Changes in Agriculture, p. 232. Numerous design changes increased reaper versatility. Besides the reduction in draft discussed above, the Kirby machines marketed in the last half of the 1850's introduced independently suspended finger-bars. “This independent action and flexibility of the finger-bar, lessens the liability to breakage when in contact with obstructions.” The finger bar could also be easily set at any desired height.
