hi there. Was just wondering when approximately the front ends went from round to square?

im of the understanding it was around 1947, though I am not 100% on this, so I stand to be corrected by someone with better knowledge.
Cheers

47 was the year that the VAK1C Cropmaster went into production but they had the rounded
Front end then. I'm after the approx year when the square block front was introduced

The square front models were introduced in April 1950.

I disagree on that Andy, my 1949 Cropmaster has a square front casting and this isn't an item that's been changed.

I always thought that the front casting changed in about 1951 with the introduction of the diesel Cropmaster.

The Cropmaster Diesel was first producuced (production model)in November 1949, the early prototype had a rounded front.
There were/have been various rumours that the early ones had rounded fronts but I think it is a rumour.
The date I gave is the one in the Stuart Gibbards book (part 2) which is the date for the petrol/TVO (I should have been clearer on the TVO bit!!!)

Since my earlier comment I have realised that you are after the date for the VAK1C front end, my apologies, I was mistaken and used my VAD1C as an example, this being 1949 with a square front. I will check the date stamp under it tomorrow to check it is the correct one for the age of tractor but it could well be that the Diesel Cropmaster had the square front before the Petrol Cropmaster did and that others are correct with their dates.

The early castings held water that could freeze and crack the casting, as a result some earlier tractors had newer castings fitted which could throw things a bit, I had one. One thing that I have learnt playing with motors is that you can never be too sure of their service history, where it has been or what it has done.

Hi Dex,

yours should have the square front fitted (all the diesels had them), there were/have been rumours that the first 200 or so built had round fronts but I once got into a conversation with Darrell Clegg and he told me none of the production models had round fronts but the early dealer demo (Harrogate Show) and publicity pics show a round front model being used (chances are the square castings hadn`t arrived!!) and it went into production a month after it debuted at the Royal Show
Just out of curiousity what is the chassis number on yours???

It should also have twin fuel tanks fitted, the first 5500 built had dual compartment tanks fitted.

Cheers

Andy

The rounded casting should not fill with water, freeze and crack because there are bolt holes in the bottom to bolt in the front weights so any water should drain unless the holes are blocked and if the weights are in there not much, if any, water would collect and sit there.

Andy.....
She has indeed got the square front, it has also got the twin compartment fuel tanks, as have my other 2 diesel Cropmasters.
For curiousity purposes, it is quite an early one, I would prefer not to say number out here as I don't know how safe it would be from "malicious" sorts who could use the info in a bad way, but if I said the date stamps on the castings were 14/11/49, that should give an indication of approximately how early it is :lol:
Cheers

I have also heard of the 'rounded' casting cracking, I know they should not crack, but they clearly do. Presumably they get filled with dirt / soil etc. The DB castings are prone to accumulating dirt, even on later Selectamatic type models, which have several holes.

We have a thresherman which has had it's rounded front casting stitched back together

The rounded castings are very thin.
