The Caterpillar CT660 Vocational Truck line was introduced in 2011 and was Caterpillar's first entry into the commercial truck sector.

This model is a day cab tractor coupled with a Trail King lowboy trailer.


As usual for a Norscot model the box is the standard style with the model tied very securely to the base.  The review model had no defects or missing parts.

The box mentions the engine of the tractor but there is no other detail about the real machine.  There are a few details about the model.


There is some detail under the CT660 although the transmission is incomplete and one of the plastic mouldings is hollow underneath.  The engine and gearbox look good, and the tyres have a good tread pattern and are mounted on plastic hubs.

At the front the radiator looks realistic with all the shiny chrome work being plastic.  The air horns look too short and the exhaust stacks too thin compared to photos of the real truck.  Under the hood the engine is well detailed.  Mirrors are plastic.

Inside the cab the seat backs have Cat printed on the back, although the steering wheel appears set too low.

Behind the cab the detail is fairly simple with completely smooth wheel arches, the light bar has lights coloured, and there are real rubber mud flaps.

The trailer gooseneck has a good structure with simple details, and some good graphics.  Underneath the deck, the structure is reasonable and the deck width extenders are represented within the casting.  The trailer deck is good with a realistic timber patterned surface.  At the rear hoses are modelled within the casting on the underside and the rear light bar has painted lights and small graphics.


The front axle steers a moderate amount before the tyres foul on the wheel arches, and the wheels are loosely mounted on their bearings.

The hood of the tractor opens forward fully and can stay posed open.

The gooseneck of the trailer can be detached from the trailer by unlocking a clip underneath although it is initially very hard to pull off probably due to paint thicknesses. 

The loading ramps can be folded up, or down for loading.


This is a moderate quality model with significant plastic on the tractor.  The paintwork and graphics are satisfactory.


In terms of price it is an inexpensive model given its overall size.


It is good that this model of the CT660 has been produced although it has not been pitched at the higher end of the truck collectibles market in terms of detail and quality.  However it would fulfill the requirement of any collector wanting to display their Cat construction machines being hauled.


The model was produced in tandem with the introduction of the real machine and became available in mid 2011.
