The Caterpillar 301.7 CR Mini Hydraulic Excavator weighs around 1.8 tonnes.

It is used for smaller earthmoving and other applications.

Packaging

The model comes in the usual excellent packaging.  There is an outer shipping carton which contains a tin which is protected by a nylon bag.  The tin is high quality and includes pictures and details about the real machine.

The review model had no missing parts or defects.

A mini catalogue of the Diecast Masters range is included.  A simple instruction sheet describes how the operator can be inserted in the cab, and a tool is provided to help with the task.

Detail

The undercarriage is metal and the tracks are rubber.  They track frames do not have working rollers, but a nice small detail is the tiny graphics on each frame.

The dozing blade has got wear plate detailing and the hydraulic ram has a protection cover on top.

The open cab has got plastic mirrors and the grab rail is modelled as a solid part of the cab frame.   The plastic roof has a window.  Inside the detail is very good with Cat on the seat back.  An operator wearing bright high visibility clothing can be fixed in the cab. 

The body casting has indented panels and the Cat graphics are very sharp with the rear lights painted.  Grilles are represented by graphics.  

The boom and stick connections are made by painted rivets.   The hydraulic rams look a little thick.  There is no hydraulic hose detailing but there is a Cat graphic adding detail.  The quick connector at the end of the stick is plastic.

Three work tools are provided.  A digging bucket and grading bucket are metal parts.  A small hydraulic hammer is metal, and a plastic auger is also included.

Features

The rubber tracks are tight, but can be made to roll by hand.

The blade moves down significantly, but upward movement is limited.

The boom, stick and bucket movements are compromised but most normal poses can be achieved.  The boom can also be angled from side to side by a reasonable amount. 

The operator can be installed in the cab for when the model is posed working, or the cab can be empty to represent the machine being parked up or transported.

The four tools give a variety of display options.  They clip on to the connector fairly easily.  The auger is long part and the boom and stick cannot be raised high enough for it to hang vertically.

Quality

It is a robust model with some plastic used.

The paint is good and the graphics are sharp.

Price

It is reasonable value.

Overall

The Diecast Masters packaging and presentation is excellent.  This is a very small model in 1:50 scale but it looks convincing.

Footnotes

The model became available in May 2019.
