The Caterpillar D7E in pipeline configuration has an operating weight of around 26 tonnes.  In this configuration it has a rear winch fitted.


The model comes in first class 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.

An instruction sheet describes how to install the operator and a mini catalogue of the Diecast Masters range is included.  Two spare fixing screws are included.


The underside has some detailing within the casting.  The metal tracks are nicely detailed with bolt heads.  The track frames do not have working rollers and the drive sprocket is plastic with a slightly off colour match.

The cab structure is metal with a plastic roof, and there are plastic grab rails.  Inside the cab the detailing is very good, with the Cat logo on the seat back.  A separate operator is in the usual Diecast Masters style. 

Behind the cab there is a nice grille and also a plastic access ladder.  The winch is mainly modelled in metal other than the winch cover.  Hydraulic hoses are included.

At the front the engine cover has grille details formed by graphics and the exhaust and air intake are plastic.  The front grille is plastic and it looks good.

The metal dozing blade has wear plates detailed at the bottom.  There are hydraulic line running to all cylinders.  The blade frame is secured by black screws so they stand out a little, but that has been done as they are designed to be easily removable.


The tracks roll very easily in the hand and are spring-loaded. 

The operator can be installed or removed by detaching the roof, and this gives good display options.

The winch can be rotated.

The blade can be raised and lowered and the mechanism is reasonably stiff.  There is no usable tilt function.   Out of the box the blade is angled to one side, but by undoing a screw on each side the blade can be repositioned to straight or angled in the opposite direction.  However, the blade is not removable.


It is a good quality model with a high metal content.

The paint is good and the graphics are sharp.


It is good value.


This is an interesting variation of a Caterpillar track-type tractor, and it is enhanced by the adjustable blade angle and removable operator.  It would be nice if a future model has a removable blade for transport displays.


The model first appeared in August 2018.
