The TerexTG190A Motor Grader.
Terex picture box.
The front axle steering has a good hard lock, and it is helped by articulation at the cab.
The blade at the front lowered.
Slightly tinted windows on the cab.
Highly articulated floating rear axles.
Travelling as a load on a Nooteboom Pendel X Low Loader.
Motor graders are used to provide a finished surface on excavations, mostly roads, prior to laying surfacing such as asphalt.  With a skilled operator they can work to fine tolerances and minimise the waste of expensive materials.  The Terex TG190A has an operating weight of nearly 19t (41,000lbs), and is capable of travelling at 40km/h (25mph). 


It is supplied in the standard box style for Terex models and is held tightly within expanded polystyrene trays.  The review model had no defects or missing parts.

No information about the real machine is provided with the model which is a pity.


The tyres have a good tread pattern and they are mounted on very good metal hubs which are different for the front and rear axles, and they all have metal mudguards.  The wheel nuts are also detailed.

There are metal ladders which lead to the cab, which has front and rear windscreen wipers, and grab rails and mirrors.  The glass of the cab is slightly tinted so obviously grader drivers are a higher class of operator.  The seat and steering wheel is provided, with the wheel having a knob for one handed steering. 

Behind the cab, the simple lines of the real machine are replicated well and there are metal lighting stalks and an exhaust pipe.  At the rear a six tine ripper assembly is of heavy construction and features nicely delineated teeth.

The front frame structure is a simple casting, and hydraulic lines to the moldboard, front axle and front blade provide detail.  The circle and A-frame drawbar are neat, and the hydraulic assembly for control of the moldboard is very good, with particularly good detail on the hydraulic cylinders.  A very small pair of signs warning of danger are legible.  At the front, there is a metal light bar with painted lights, and the front blade has a wear plate on the lower edge.


The front axle has a good range of steering although not quite as much as the 45 of the real machine.  It also has an oscillating range up and down, although this version of the machine does not have an option to lean the front tyres.

The steering is also aided by articulation of the front frame and this approaches the 30 possible on the full size grader.  The rear axles also oscillate and the range of movement is surprisingly good.

At the rear, the ripper assembly can be raised and lowered, and the same is true of the blade at the front.  Movement of the moldboard is very good.  It can be raised and lowered, and rotated on the circle.  It also has a range of tilt movement (both side to side and forward and back), and the blade has significant side-shift available.


The quality of this model is very good, with very little plastic used.  The paintwork is to a high standard and this is matched by the quality of the graphics.


This model is very good value for the quality and functionality offered.


NZG have executed this grader model very well, with all the main functions of the real machine replicated as working features.  The detail level is also high resulting in this Terex model being highly recommended.


The model was announced at the Nuremberg Toy Fair in 2007.  It appeared as model 638 also, which was a version in yellow, the colours of HBM-NOBAS, the original manufacturers of the machine.

The model held tightly in the box.
The moldboard (grading blade) is lowered.
Ripper tines at the rear.
Rippers down.
An impressive model.
