Hello,

in the past few weeks I decided to mod the Set 42121 and create a compact excavator in scale with my truck models (around 1:21).

I tryed to minimize the use of extra parts, for this reason you see, for example, a clear operator seat.

 

The movement range of the arm is improved compared to the official set, now the bucket can be closed a little more.

There is also a functional blade. 

All functions are manual.

Here you see a photo of the excavator working with my Man Tgx:

Instructions for both models are available here:

Very clean, playable and presentable sets.  Well done....

I'd say it's more of a midi than a compact, but good job nonetheless.

Yes, midi excavator is the right definition.
