The PR 736 G8 is a hydrostatically driven tractor. This is the low ground pressure version with wider tracks. It has an operating weight in the range of 21 to 24 tonnes, and has a maximum travel speed of 11km/h.

This model is an update of previous models to reflect Generation 8 of Liebherr Crawler Tractors.


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.


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 on this version of the model are painted yellow. 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, and is painted black to represent 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 6-way blade is good with wear plates on the bottom edge and the hinged corners are represented in the casting but are not functional.  The blade mounting is complex with multiple hydraulic hoses.


The tracks roll easily and they are tensioned by spring-loaded idlers.  They are formed of individual hook links so care is required not to separate them as reforming and fixing a complete track is a challenge.  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 angled from side to side.   A degree of rotation of the blade is also possible. 


This is a solid model with a high metal content.

The paintwork and the graphics are of a high standard.


The model is good value.


This update to previous versions of the model is a different combination of blade and tracks, but in other respects changes are cosmetic.  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.


The model first appeared in November 2014 as NZG #926 and #927.
  This revised version was announced at the Nuremberg Toy Fair 2020 and appeared in March 2020.
