TAS Country : September 30th 2010
22 Tasmanian Country Friday, October 1, 2010 Tractors The Deere with the The model 435 had the distinction of being the first tractor to be tested at the Nebraska test institute with a 2-speed power take off unit and was no doubt a popular option to be had. TRAGIC Tractor Glenn Shaw BY the time of the model 435 tractor's release, three point implement mounting was becoming regular fitment to most general purpose tractors. For those requiring it, remote hydraulics could also be optioned to best tailor the model 435 to your requirements. Being based on the gasoline model 430W, the model 435 diesel was a standard tread tractor with row crop adaptability by axle adjustment. At the front end was a standard axle that offered track adjustment from 48 to 80 inches wide on 5x15in diameter tyres or the option of a wider axle that could take adjustment out from 56 to 88 inches on the same 5x15 inch tyres. If a tighter turning circle was required you could have a third axle option which was a swept back design with 56 to 80 inch track adjustment. At the rear end the standard wheels ran on axles of two and a half inches diameter with sliding hubs that allowed infinite adjustment between 48 to 98 inches on the optional 10x34inch rear tyres and 56 to 90 inches on the rears. Optional fitment were the power adjustable rear wheels fitted onto a dished centre. The dished design of the wheel centre allowed 56 to 80 inches of adjustment with the centre wheel dish facing in, or 64 to 88 inches of adjustment with the centre wheel dish facing out. Self energising disc type brakes featured on the model 435 which were operated by foot pedals independently. The disc brakes were an extremely effective unit and didn't require the frequent adjustment that was necessary on the band type brake design. Apart from customising your model 435 with the options available there are differences to look for in respect to factory modifications and the main one to look for is the change to the design of the governor guard on the GM 2-53 engine. At tractor serial number 437928 the holes in the governor guard were deleted --- a novice playing around in this area on a supercharged 2-stroke diesel was asking for trouble if they were not sure of what they were doing. A few tractors later on, from serial number 437937 a change was made to the throttle lever and other smaller changes to be implemented to the model 435 included a new type of fuel tank valve elbow and a modified fuel tank vent line at serial number 436527 and 437626. While most model 435 diesel tractors were built at the Dubuque Iowa factory, there were 371 examples built at John Deere's factory south of the border in Monterey, Mexico. The last John Deere model 435 was built on February 29, 1960 ending the shortest production run of any John Deere tractor. Despite this, John Deere managed to produce some 4626 examples of the model 435 so in terms of numbers built it is not rare in quantity, but its distribution is. As soon as the ''new generation'' of multi- cylinder John Deere tractors was released the model 435 was dropped and replaced with the 4-cylinder model 1010 which used virtually the same rear end as the two-cylinder model 435. To some, the 1010 was a poor replacement for the 435, a big criticism was the rev range/power delivery of the 1010 was nowhere near as good. While John Deere in USA had given up on the model 435, it got somewhat of a rebirth in John
