Impressive mining model.

The Caterpillar D11 Dozer - TKN Design has an operating weight of around 104 tonnes.  It is used for large quarry operations.


The model comes in the usual exemplary 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.  There was a slight blemish which had been painted over in the factory but was still visible.

A mini catalogue of the Diecast Masters range is included, and a single sheet describes how to place the separately provided operator inside the cab using the included tweezers.


The underside has some detailing including the transverse beam connecting the track frames. It has the model number 85565 in the casting with 85604 added as a graphic. The metal tracks are very good and have bolt head details.  The track frames do not have working rollers, and the high drive sprocket is plastic with a good colour match. A tiny graphic is applied at the back end of the frames.

The triple-shank ripper assembly is metal and the teeth are sharp.  The rams are plastic but they are detailed, and there are many soft hydraulic hoses.  

The cab structure is metal and the side wipers are formed within the casting.  The black hand rails are metal and thin, and the only plastic rails are on the track frame.  The inside of the cab is detailed with the Cat logo on the seat back and graphics for the instrument clusters which is a nice enhancement of detail.  The roll over protection structure (ROPS) has small lights with cabling highlighted in black.  The folding access ladder on the side is plastic.

The new style Cat logo is applied around the model, and a number of incredibly small graphics provide enhanced detail.

The walkway around the cab has a textured surface, and there is fire suppression equipment at the rear with red coloured hoses.

The standard Diecast Masters operator can be placed in the seat. 

At the front the engine cover has grille details formed by graphics and the exhausts and air intakes are plastic.  The front grille is very good and there is a tiny Cat logo on top.

The metal U blade has wear plates detailed at the bottom and it is good to see perforations in the grille on the top edge even though that part is plastic.   There are hydraulic lines running to all cylinders.


The tracks roll very easily and are spring-loaded. 

The ripper assembly is very stiff and has very good movement.  It can be parked high or positioned with the ripper down, and the angle of the rippers can be adjusted.

The blade can be raised and lowered and the mechanism is reasonably stiff.  Some side tilt is possible and the forward tilting function has an excellent range of movement.

The rotating access ladder sits well in the parked position, and clips in while the dozer is operating.

There are opening engine covers on each side and they allow a view of some engine detail.

The ROPS and cab roof is removable allowing the operator to be placed in, or removed from, the cab.  This is flexible arrangement allowing the model to be posed working, or parked with the operator in the cab or out as appropriate.


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

The paint is very good and the graphics are sharp.


It is good value for a large model.


This latest version of the D11 from Diecast Masters is improved and in particular the detailing level is higher with some tiny graphics added.  Overall, the model looks great.


The model was announced at the Nuremberg Toy Fair in 2020 and was released in May 2020.
