Here is an improved version of a backhoe that I whined about earlier.
modifying my train engine let me add the blade and shovel while keeping the proportions a healthier 2x1. I like the different sized wheels , so I'm content with not getting a color change, like on the bulldozer or excavator.
This uses the narrower shovel which looks better, but does require folding into 32ths, making for a very thick arm and shovel.
