Can anyone help identify this tractor and harrow?

Hello, I am sorting out some old Matchbox model vehicles with a view to selling. Can anyone help identify these two items? And do they have rarity value? I don’t know if they originally formed a set.

(1) A 1950s caterpillar tractor. It has no name or number imprinted on it but it is similar to the Matchbox Lesney 8A models. However it differs in several ways from any of the other models I have seen photos or descriptions of.
It is yellow (like 1955 and 1957 model).
It has a yellow driver (like 1957) but the remaining paint on driver’s hat is also yellow (1957 models apparently have black hats).
It has yellow wheels (like 1955).
The area below the steering column, between the driver and the engine, is filled in (in other models it is open).
The back of the driver’s seat is lower than in other models.
The engine is narrower and more ‘open’ in style than any other models I have seen.
The ‘chimney’ is a different shape and near the centre of the engine (other models have it near the back of the engine).
The tow hook is set lower on the back than in some models.

(2) A harrow, which seems to be the same scale as the tractor but is a slightly different shade of yellow. It has no distinguishing marks but it is known to date from the same era as the tractor and is assumed to be Matchbox brand. I have not found anything else quite like it. Does anyone recognise this?

Many thanks! It was so similar to the Matchbox ones that I didn't realise it was another make. From the link you gave it looks as if it normally came with a hay rake, not a harrow. Can I assume the harrow is also Benbros make?
(Edit: I have answered my own question now. Just found it. The harrow came with the tractor as Benbros number 19. Many thanks again)

I think I have just answered my own question. The harrow came with the tractor as Benbos number 17 . Many thanks again for the speedy response!
