The last of the Tractor 'sets' in the Benbros TV Series was No.19 Tractor & Trailer, the others being No.10 Bulldozer, No.11 Tractor & Hay Rake, and No.17 Tractor & Harrow. Like these the first version of No.19 had an orange tractor with green tracks and silver trim on the engine and grille without an apparent seat for the driver. Benbros soon recast this to include a seat for the remaining models. 

The Trailer had several variations. It was a low-level model with good detail on the upper side but with an underside which was quite smooth without identification. It was a single casting including the towbar which attached to the little hook at the rear of the tractor.

The first issue of No.19 had an orange tractor, initially without a seat, and a green trailer fitted with unpainted metal wheels. It came in a numbered TV Series box (TV3).

At about this time Benbros was switching all models into the Mighty Midget range and as part of the new look the tractor colour changed to deep yellow for the new box but kept the same green trailer. There was still no identification on the tractor or trailer.

Next, the trailer had a colour change to red which later became a darker crimson-red. The wheels remained metal but eventually were replaced by black plastic when the change to darker red happened. The axles for all the trailer versions were nail-head & crimped.

The final change to the Tractor saw the addition of identification in the form of 'Benbros Made in England' cast on the left side above the rear roller and beneath the mudguard. It was not easily seen behind the green track. These versions were painted a more lemon-yellow colour and often had a lot of scarf and infil around the driver from the poor casting.

No.19 Tractor & Trailer is fairly easy to find in nice condition but the first issue TV3 box is rare and the red trailers are more scarce than the green ones.
