Eska D17 Pedal Tractor
D17 Series I at Marshalltown, IA
The D17 Allis Chalmers originally came out in 1957 as a replacement to the WD45. It, along with the smaller D14 introduced the "power director" clutch. The power director used two clutches - one a conventional foot clutch, the other, a hand clutch. The hand clutch had both a high and low position. Another innovation was the roll-shift front axle, which allowed you to use tractor power to help make front axle adjustments. The tractor was tested at Nebraska under test 635 and 636. The 4 cylinder 226 ci gas engine developed 52.70 hp, the 262 ci 6 cylinder Allis diesel produced 51.14 hp. The tractor was produced in four series, until 1966 when it was replaced by the 170. The D17 series four included live hydraulics and 3 point hitch. The real and toy D17 tractors are very popular collector items today.
