AMT Bulldozer 1/25
This is the AMT kit that was originally titled "Caterpillar D8H" but has been re-released as the generic "construction bulldozer." It's a great kit, very detailed, and very much capable of even more scratch-building detail. I limited myself to adding hydraulic lines to the main cylinders, lines behind the dashboard, and lines connecting the 'dozer to the ripper attachment. Shortcomings of the kit would be the tracks, which are individual links but not very accurate, no numbers on the parts, and of course, no actual Caterpillar decals.
I painted mine Implement Yellow in a rattle can, then shaded the upper surfaces with Vallejo Air Yellow for fading affect. The bare metal surfaces are Testers Rubber, with Testers Rust in spots. Tamiya Tan was used for the dirt color - the dirt being made of Tamiya body putty and dried play-doh under the treads.
It's not exactly a tractor, but is a nice addition to my tractor collection. I hope you enjoy it.
