In determining the radiator’s forward and aft location, the distance between fan and radiator core was held to the same as for the JD “H.” Shimming between radiator and FES for elevation plus radiator mount centering would align the JD “H” fan and fan shroud. The radiator chosen was from a 1935 JD “B” and to accommodate the lower tank required widening of the front end support (FES). Starting point: Since the relationship between fanshaft and governor on any JD tractor is very delicate, this was the place to begin. Some liberties would be taken, but in general, even the decals would be selected to date this tractor as a vintage 1935 JD “HNH.” Design criteria called for a “finished” look in all areas.
The new tractor must appear to be one that could have come from a Deere factory. The unstyled JD “B” pedestal would be remanufactured to accept a vertical spindle shaft with yoke from a “BN” tractor to convert to a typical Hi-Crop configuration to fit the JD “H” chassis.Įngineering and design: The result was to be a new tractor, but of vintage 1935. Since narrow front and higher crop clearance would be even more rare, conceived final construction would have a single yoked wheel up front and 38 inch rears.
The concept: “New Johnny,” as it soon would be named, was to begin with a working JD “H” tractor, serial number 10,000 or higher, the front parts from an early unstyled JD “B” tractor plus (perhaps) some wheel parts from various tractors if needed. The idea: If John Deere were to have built an unstyled model “H” tractor in 1935, this was to be the tractor Deere would have built. Unstyled JD “HNH” – Conceived October 2006, built 2007
