What is in this image? Be very specific. Scientific, Engineering style! No emotions, no opinions, no metaphors. Just the facts, as detailed as possible.

The image depicts a simplified, cartoon-style drawing of a tractor towing a trailer. The tractor is to the right facing left and the trailer is attached behind it.**Tractor Details**- The tractor has a prominent, rounded cab with a noticeable roof and a large, somewhat rectangular front window.- Towards the back on the top of the tractor, there is an exhaust pipe sticking vertically.- The front of the tractor shows a small, square like feature, possibly representing a headlight or a brand mark.- It has two large wheels, both circular with basic inner detailing suggesting wheel rims.**Trailer Details**- The trailer has a semi-elliptical shape, appearing almost rounded on top and flat at the bottom where it meets the wheels.- It features a series of evenly spaced circular patterns along its side, with a total of ten visible circles, possibly representing rivets or decorative elements.- The trailer has two wheels, similar in design to those of the tractor but slightly smaller in proportion.Both the tractor and the trailer are connected by a simple, short cylindrical hitch. The overall image is outlined with bold black lines, ideal for coloring. The styles of the wheels and the shape of the trailer provide ample space for creative coloring.
