RE: DB 780 - Three place control mechanism

This is how it goes in simple terms, other people will give you a deeper understanding! Height is for an implement above ground (eg a manure spreader or a transport box) and is not linked to the top link at all. You can set the "marker" to the lever's position so that you can go back to the same hei...

RE: Steering problems with 1212

I had a similar problem with my 995, but it had all new ball joints (the old ones were somewhat sloppy!) - if you have a side-mounted ram, try changing its oil seals. I had more than one expert who suggested the orbitrol was wrong, so changed that first - not cheap compared to new ram seals!

RE: Cropmaster not running well on TVO

I can't add much other than to say that when I used a Fergy many years ago (in the 70s), the local garage said 4:1 and a bit of two stroke oil too - this helps replace some of the oil that Kero washes off the bores! The Fergy had been brought back to life as the 990 Imp had sheared the rivets in the...

RE: 1490 three point hitch

I suspect the selector valve is in height rather than depth (draft and position are MF terms!) and, in height, the arms won't go right down: most implements need to be clear of the ground when working in height! The selector "switch" has the Depth position to the left (ie lever pointing roughly to t...

RE: 780 Foreloader (or Front Loader)

There's a photo of a 770 with loader in the "DB Tractor Range" section that shows the pipes, though will need to zoom in a bit to see them!

RE: 780 Foreloader (or Front Loader)

I would suggest a tap on the loader's feed if it is connected to the tipper pipe. If you don't, there will be a time when you need to lift or lower the loader while using the lift arms and have to reconnect the Dowty coupling (which you would have to unscrew with the loader up if you leave the loade...

RE: Spark plugs wanted

A handy place is "The Green Spark Plug Co"

The link to the NGK plug is here:

http://gsparkplug.com/1x-ngk-spark-plug-f23.html

It also lists alternatives, which may help if you can find those locally!

RE: Lift pump lines still leaking (990 implematic)

The tip I was given by a heating engineer is to wrap some PTFE around the olive and give it a good smear of red gasket sealer before screwing the union in - just don't overdo the PTFE though! Obviously, some heating unions are larger (and new olives!), but the principle applies and seems to work wel...

RE: What is it about balers ?

The B45 was a really slow baler compared to the B46 - I seem to remember that it had a much smaller flywheel and the drawbar was crude (if memory serves you had to move the tractor's drawbar). I can't remember exactly if the B46 could handle poly string - the 45 certainly couldn't but I seem to reme...

If you want pedantry, it is draft (as ollek has spelt it) and not draught! My 995 has a brilliant example of the latter - I must put the panel back below the windscreen as it really makes the fingers cold without it! It's a long time since I saw the film, but perhaps it was phrased so that someone w...

RE: Starter Issues

Yes, ollek is right - a battery will have around 12.5v when not loaded. I was thinking in "Ideal" terms rather than real world ones! "Ideal" meaning the battery has no internal resistance and the meter has no loading effect: in the real world, that never happens. Out of passing interest, I measured ...

RE: Starter Issues

If the battery is only giving 12v it is either flat or is getting to the end of its life - it should be giving a good 13v (13.2 typically as each cell should be at 2.2v). Check the voltage when cranking - it may be going too low to be effective. Connecting a second battery by jump leads should impro...

RE: different sizes of weight frames????

This was discussed a while ago, I remember Scooby pointing out to me that the fold-down frame could be used with a weight frame (and then I noticed the photo of his 1212 with both earlier in the thread!). The topic is here, though the photos are no longer visible (or wern't from my computer!): http:...

There is a section of the forum for shows etc and I am always willing to add shows to it. the section has to be "managed" by moderators so that the shows end up in date order and thus the section should have the "next" show at the top of the list.

It will probably be repeated during the week too! I thought there was an odd inaccuracy or two. Apparently David Brown made his money making farm tractors in the second world war!
