Hi all,
My names matt, I’m a new member on this site and already a fan with the info I have read.
I have recently inherited my grandfathers 1952 David Brown cropmaster diesel. It’s completly original and that’s how I intend to keep it.
I have a few questions if there’s anyone on here that can help, firstly I need to get a couple of new battery’s, I believe they are 6v units, where is the best place to get these?
I intend if possible to use the tractor for road runs and also topping a small paddock, I’ve been looking at a few toppers but do I need to look for anything specific? Size etc? Will they all fit?
I’m not too clued up on any of this yet.
Thanks,
Matt

I personally use batteymegastore.co.uk
Most people use the largest 12 volt battery that will fit in the battery carrier in place of two 6 volts. You can still obtain 6 volt batteries but they are expensive and most of them are of dubious quality. To keep the original look you can use dovetailed wooden boxes with a CAV logo with a modern battery inside.

Welcome to the Forum. You have a very desirable tractor and with it's history will be something that you can talk about on treks and be able to offer the history of it in your family.
Banking 6v batteries will obviously work but as advised they are expensive and due to the low manufacture rate are fairly ordinary. Consider running the 12v battery and confirming the polarity of your system as it should be positive earth and then checking the output of the generator as you will need it to be a 12v system.

Thanks for the replies. It's seems a single 12v battery might be a better option.
I will get some pictures added over the weekend.
Regarding implements, does anyone know what the cropmaster is capable of power wise? I think really all I will use it for its topping a paddock,
There's a 6ft topper for sale local to me, would this be ok on the back or should I go for a smaller 4ft one?
Thanks

Driving a small topper would not be a problem in my opinion. There could be a problem with the hydraulic system lifting capabilities. The hydraulic pump is old and new ones are not available.

Thanks db2d.
Il stick to Looking for a small 4ft topper.
It's looks like there are loads around but they all say for a compact tractor, does this mean they will not fit mine? I was under the impression that any implements will fit?
Apologies for the very simple questions.

They should fit, check that they are category 1 lower links your DB should be cat 1, if not you could change the pins on the topper easily, also check the distance between the lower arms , some implements for compact tractors have a shorter distance between the lower links. also check the pto shaft length and the diameter of the of the end that goes on the tractor should be 1 3/8".

Just another thought, a 4' topper would not cover the tractor tracks, try and see if you could get one that is offset, that would solve the track problem.

The problem here is that there are two "types" of off-set. The first one just protrudes outside of the RH (o/s) tractor wheel. The problem with this type is that one wheel (two actually if you include the tractor front wheel) are always going to run on uncut grass and because the wheels push the grass away from the cutters then that strip will not be cut as low as the other grass is and after a couple of day when it's sprung back up again I always think it looks a bit untidy.

The other sort is the fully offset which swings out onto grass that is about to be cut and has not had any wheels running over it. But almost certainly a Croppy won't manage one like this. I think if I was looking for something to go behind that size of tractor I would look at one of the old trailed foragers that were fully off-set. Like a Kidd, Bamford, Lundell or a DB. This Bamford would do the job well but I would take the shoot and funnel off and just throw whatever is cut on the ground behind the machine. It would make a very tidy job.They do come up on eBay.
