A metal mixer drum is a decisive requirement for some collectors. If it is yours, this comparison ends quickly: the inspection identifies a plastic drum on 71033 and metal on 71075. If appearance matters more than drum construction, the choice becomes less one-sided.
| From red 4700 · 71033 | To blue 4900 · 71075 | Does it solve your need? |
|---|---|---|
| Plastic drum | Metal drum | Yes, if drum material is mandatory |
| Two chute extensions | Three extensions | Only if the resulting arrangement fits; count is not measured reach |
| Simpler mixer outline | Movable pusher and tag axles | Yes, for auxiliary-axle configuration interest |
| 7.375-inch listed length | 8.75-inch listed length | A larger unspecified-pose outline, not a working-envelope measurement |
The additional equipment does not remove the front steering restriction documented on both trucks. It also does not verify the 4900 merchant’s door-opening claim. Those limitations should remain outside any argument that the blue truck is the better-equipped choice.
For the red truck buyer, the meaningful sacrifice is drum material and axle interest—not every function. The 4700 still provides drum rotation, chute positioning and engine access. Choose its decoration deliberately rather than treating it as a failed version of the longer truck.
