30D smoking and gov not working

My 1950 Cropmaster with the 30D motor is causing me some problems...it runs well-ish, but it smokes hot or cold, and if I am running an implement or driving, if I set the throttle at say 1400RPMs, let out the clutch and it will drop to around 800 or so depending. Also on the open road, I can get it ...

Re: Cropmaster Clutch

When I fitted a new clutch assembly in my 30C I just put the old assembly on the counter, gave him the details of the tractor and he looked up the replacement assembly which too 2 days to get in. Complete assembly including the thrust bearing. Was not a hard thing to find here in Oz. I figured it w...

Re: Cropmaster Clutch

Thank you. What clutch did a 25D come standard with? I have a pressure plate off a 25D and a pressure plate off a narrow pulley Implematic(was thinking a 900 but poss 850?). The 900 clutch has yellow springs - what would that be rated for - heavy or light?

Cropmaster Clutch

Hello, As some of you know, I put a 30D motor into my 1950 Cropmaster(and put the original petrol clutch on the motor), and I am finding that the clutch is far too light when I am operating a topper. It is chiefly starting off it slips majorly if I'm not extremely careful. Is it possible to upgrade ...

Steering box and hydraulics

Hi, Will a 780 steering box go onto a 990? Not sure if the 990 is red or white, the person asking didn't specify. Also, I've got a implematic 880 and with good revs the hydraulics lift a fraction every 5 or more seconds. I've checked and the valves aren't stuck. That was the problem with my uncle's ...

Re: David Brown Cropmaster speed?

Never thought about doing a swap over with a TEa20 carby. It actually works alright, stud pattern etc. I got an adaptor built for it too. But only if you don't have a functional carb! Have put up a picture of carb. It is for sale - https://www.trademe.co.nz/business-farming-industry/farming-forestr...

Re: David Brown Cropmaster speed?

I was told "no, shouldn't have put the diesel in as its not compatible with diff gearing" but I said that the gearboxes are all the same(well, almost). Is this correct? I believe that those sort of changes were only in the later model tractor reduction units. On the petrol 30C the governor had been ...

Re: David Brown Cropmaster speed?

I like your Cropmaster Valiant, looks a very nice project and now a diesel powered one. I just looked in some of the old booklets I have and the largest size rear tyre listed with speeds is the 11.25 x 28 @ 2000RPM = 18.95 mph. they do list a 12.25 x 28 but no other info. As for our 30C I fitted 14...

Re: David Brown Cropmaster speed?

Hi Geoff, I'm in Palmerston North, I sold you those two engines a while back. Does it damage the engine to run it without the governor? When I put a 25 petrol in my 30C the governor had been removed and it scared me at times till I fixed that. How is the 25D engine compared to the 30D engine? Late m...

David Brown Cropmaster speed?

Hi all, I have a David Brown TVO Cropmaster, gear-driven generator, square front. I recently put on a reconned 30D engine I picked up off Trade Me as the petrol engine is seized. A question though - what speed is this DB capable of? No dash, best guess is, casting date is 1950. Picture is of it in i...
