Comment on this model.

The PR 736 XL is a hydrostatically driven tractor.  It has an operating weight in the range of 21 to 24 tonnes, and has a maximum travel speed of 11km/h.

Packaging

The model comes in a Liebherr-branded box and it is held between expanded polystyrene trays. 

There were no defects or missing parts on the review model.

No information is provided about the real machine and as the model is complete in the box no assembly is required.

Detail

The metal tracks are excellent and very well detailed with each shoe showing bolt locations.  Most of the rollers in the detailed track frames do roll.

At the rear there is a ripper attachment complete with a hydraulic cylinder with an authentic looking rubber hose.  The 3-shank ripper has teeth which are sharp and the connection pins are very small.   There is also a towing hitch at the rear and it has an accurate pin.

The body is finely detailed with highlighted bolt heads.  The cab has windows with highlighted seals together with windscreen wipers and plastic lights.  The grab rails are thin plastic.  Internal details are very good too, with the controls clearly visible. 

The engine cover has an exhaust pipe which is plastic and solid, but without a hole.  The graphics on the panels are sharp, including those used to represent grilles.  At the front the metal grille is very good albeit without actual perforations.

The semi-U blade looks good with wear plates on the bottom edge.  The blade mounting beams are metal and the hydraulic ram jackets are plastic and with thin pipes highlighted.

Features

The tracks are a little stiff but can be made to roll and they are tensioned by spring-loaded idlers.  The track frames are transversely linked and can oscillate a little to facilitate travel on rough terrain.

The ripper moves up and down with a very good range of movement. 

The blade has a good range of movement up and down, and it also can be tilted forward and backwards with three pinning points.  The small pins are loose and easily drop out if the model is tilted.  A degree of side-to-side rotation of the blade is also possible. 

Quality

This is a solid model with a high metal content.

The paintwork and the graphics are of a high standard.

Price

The model is good value.

Overall

NZG has produced another very nice crawler tractor model for Liebherr.  It is mainly metal with a high quality feel. It would have been nice if the blade and ripper had been removable to provide a little more display flexibility.
