Your battery carier is the same design as mine and it is a 1954 model. I too like the patina on your tractor. It would not take much to adapt a dynamo if you felt it would help.

Cobbadog—- The tractor is an early Cropmaster not a 30C . It was not equipped with electrics when it left the factory. The electrical systems available as an optional extra, were six volt with a gear driven dynamo and a small battery case. Fitting a conventional dynamo is not really a viable option due to the cooling system configuration

Hello db2d

Ok here is the starting handle - no idea if its right but its a perfect fit and length.

Also - your comment to cobbadog got me thinking, another thing that came with the tractor was a feed bag with an old magneto in it - so I think you're right its been changed over to the current coil & distributor at some point. Its only ever been on 1 farm in Scotland so I guess they had plenty of time over the years to 'improve' it!

All very interesting though - its certainly something I intend to keep.

Cheers
Chris

That is a DB handle supplied with later tractors and was intended for maintenance purposes rather than hand starting. The correct handle has a shorter crank making hand starting considerably easier.
Originally it would have had a magneto.

My crank handle is off a Bedford J truck. Correct length, only a fraction large for going thru the grille.

Hello all,

A productive weekend with flywheel and starter now in place - thanks for all the advice, which was invaluable and it was a good weekend to be working under cover!

I've obtained a period looking starter button and a solenoid which I'll be hiding out of sight.

So its now just a case of wiring it all in, looking at others it appears to be the positive earth cable moves to a starter mounting bolt - is it straightforward solenoid wiring from that point on? Just conscious of the positive earth arrangements...

Thanks for the help guys - really appreciated.

Chris

This is the original starter solenoid - connected to a cable on the R/H side under the fuel tank.

Of course, these are more readily available, and wire in to a push button - https://www.ebay.com/itm/274370059937?h ... SwLgNaaR6J

Generally, the wiring principles are fully the same irrespective of + or - earth system. The "not earth" wiring should be insulated and the chassis works as return path for the current. The only things that have to be considered are those that are involved with dynamo/regulator or an alternator, ast they tend to be a bit miffed if the polarity isn't correct.

The Cropmaster had a manually operated switch for the starter—not a solenoid. These are readily available and also from WWW.DAVIDBROWNPARTS.COM
Early starters had the switch incorporated on the front.

Thanks everyone - I'll forge ahead with the wiring and report back to (hopefully) close this one out.

Is your magneto a complete unit? If so it can be made work again providing your cap is in good condition.

Dont forget to include a fuse close to where you connect into the supply.

Sorry db2d, my 1st link - I meant to call it a start switch, as it is close to the original.
