Using the Caterpillar Tractor body, Benbros developed a second model in the series by attaching a large dozer-blade to the front via the axles. It made a chunky toy at over 140mm long but had excellent play (or push!) value.

As with the large Tractor, the body was a single hollow casting which included a solid front grille, engine detail, a seat, a rear hook and had 'Benbros Qualitoy' and 'Made in England' cast underneath. The two-part metal rollers were fixed to the body on nail-head & crimped axles with the outer part painted and the inner parts normally unpainted. The rubber tracks could be dark-green, bright green or mid-grey.

There was a separate metal driver of an unusually spindly casting with its arms pointing forward. It was held in place by a peg fitting into a hole in the seat and was painted red or green. Later this figure was dropped in favour of the driver previously used for the Ferguson Tractors.

The Bulldozer attachment had a front blade mounted on two side arms secured to the axles outside the rollers. The rear ones were just a hole through which the axle passed but on the front the arms had slots to enable the blade to be raised and lowered. 

Benbros produced the Bulldozer in a variety of colours. One was red with a black blade and black or yellow rollers and silver trim on engine parts; another was yellow without silver trim with a red blade and red or black rollers. Next there were two variations with metallic paint, a blue one in various shades with a yellow blade and yellow or orange rollers, and a metallic-green model with red blade and yellow rollers, both with silver trim on engine parts & grille.

The Bulldozer had its own brightly illustrated box with 'Bulldozer' in a panel on both picture faces. The end-flaps had the 'Benbros Qualitoys' crest-like logo.

Finding the Caterpillar Bulldozer is quite difficult and the box is rare. Mint examples of such a play-friendly toy are very rare.
