|  Comment on this model.
The Caterpillar 621K is a single-engine Wheel Tractor-Scraper and it has an operating weight of around 36 tonnes.
Packaging
The model comes in a Caterpillar-branded box with windows. Inside the box the model is held in a large plastic former secured with poppers.
The review model had no missing parts or defects.
The box includes a small collector card which has some information about the real machine and a photo.
Detail
The underside has detail within the castings. The tyres are good and they are mounted on plastic wheels.
The tractor is detailed well, with some fine casting of textured areas. The black grille at the front looks good and it has a Caterpillar logo. The handrails are metal with various access ladders being plastic.
The metal cab has good detail inside with nice controls including an offset steering wheel, and there is a Cat logo on the seat back. Small aerials and a horn are on the roof, together with a painted beacon light which does not look as good as a clear plastic version would. There is a windscreen wiper on the front windscreen.
The connection to the bowl is very detailed with plenty of soft hoses, which all looks convincing. The elevating mechanism for the bowl is also detailed with hydraulic hoses. The bowl is metal with some nice graphics.
At the rear the anti-spill guard is modelled in metal, as is the robust pusher point at the back. The handrails and laser sensor are soft plastic.
Features
The wheels are free rolling. A particular plus point is the steering which achieves an angle of almost 90º between the tractor and the bowl.
The gooseneck hitch can be elevated using a small hydraulic ram although it struggles to hold an elevated pose.
The elevating mechanism for the bowl is stiff but it allows realistic cut and carry angles.
The apron raises and lowers and poses in any position.
The ejector can be moved forwards and backwards although it is a clunky mechanism.
Quality
This is a nice model with a high metal content.
The paint finish is very good and the graphics are sharp.
Price
It is reasonably priced.
Overall
This is a good scraper model with a blend of detail and features.
Footnotes
The model was available in Europe from mid 2015.
