This model set traces the history of Caterpillar D7 Track-type Tractors.  It includes models of the D7C and the D7E, and also a book describing the history of the D7 series.

This set as one of Diecast Masters Evolution series.


The set comes in excellent packaging.  There is an outer sleeve which covers a high quality box.  The box has a hinged lid with a ribbon restraint.  Inside the box there are reprints of relevant marketing sheets, and various photos of  machines in the series.

The review set had no missing parts or defects.

A mini catalogue of the Diecast Masters range is included and there are two parts which have to be fitted.

The set includes a comprehensive 64 page ring-bound book.  It starts with a written history of this series of machines, and there is a large photograph section.  There is also a comparison of machine specifications.  It is an excellent reference work to accompany the models.


The models are fixed to a base plate which has nice quality badges embedded.  The models are fixed by screws with stands. 

The D7C has nice metal tracks and the old fashioned spoked drive sprocket looks great.  At the rear there is a towing hitch and a large plastic winch arrangement.

The operator's area has replica levers and it is nice to see an operator which is is fixed in position and is in period clothing.   A plastic umbrella provides protection.

The engine block has a plastic engine which is detailed, and the exhaust pipe has a hole at the top.  At the front the radiator grille looks convincing and it has the Caterpillar name on top as well as couple of work lights.

The blade has wear plates on the bottom and a tiny Caterpillar logo.  The track frames look good too, with black screw heads the only blemish.

The D7E 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 lines 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 D7C tracks can be rolled.

The blade can be raised an lowered.  It can also be repositioned from angled one way to straight or angled the other way by removing two screws.

The D7E tracks roll easily. 

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.   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.


The models are very good quality with nice paint and graphics.

The presentation of the set is excellent.


The set is good value for two models and a reference book.


Once again the Diecast Masters Evolution Series delivers another exceptional package, with the book being an excellent reference work. 


The set first appeared in 2019.
