Intel , My DK50 looks identical to the older DK45 with out the sloped hood . Its drivetrain looks identical to the newer DK45 and the cabs are the same the newer hoods just look different. My 50 is basicly a DK45 with a turbocharged DK40 engine. I beleive the last year they were built was 2004. The front axles should be identical. Although the last few years they have made upgrades. Such as beefier hydraulic steering cylinders and upper steering knuckle (kingpin caps?) braces. I study the larger kiotis religiously to see what is new and has changed. I constantly stop and look at tractors when i see some that look interesting. The DK55 is much larger although some early models 2003? looked to have the same front axle as the 45 & 50 only with spacers out at the ends to widen them. If Deprat or Wallace are on here I would like to know If there is an upgrade kit for the knuckles to add the upper braces. I know they made them for the early DK55s. nice talkin. FRENCHIE
