The Association of Equipment Manufacturers reports sales of under 40-horsepower tractors jumped 23 percent in October compared to last year. That represents an eight percent increase for the year. AEM Senior Vice President Charlie O'Brien noted that many of these tractors are going into small-acre farms and the livestock sector, where economic conditions have been more favorable compared to row crop operations. Sales in the two-wheel drive 100-horsepower and above category dropped 29 percent for the month when compared to October of last year, resulting in an overall reduction of 23 percent this year.
