Thanks for the reply Martyn. When I first looked at the picture I thought the pin eyes on the bucket were side by side.
I'll guess it was a sluggish old beast on the move with a Fordson Major engine.

It was a monster on the road, from the road surface to the tip of the dipper in traveling position the height was 19 ft .. you really needed a full 45 gallon drum and as many buckets you can cram in the front bucket to steady the beastie on the road...

Regarding the JCB 4 range i found these pics on my files, its 1970 JCB 4D, i belive this one was found in Evesham,Worcestershire, and i think i am right in thinking that this is the one that Mike Eacock is restoring.

You could get some serious trenching done with that backhoe, I notice on the very large JCB backhoes like the 3D and 4D have the backhoe kingpost (?) fixed in a central positon without the rails to slide it left or right like the smaller 3C.

IBH.. no it was only the 4D that had the kingpost fixed to a central position, the 3D had a sliding kingpost belive it or not

I could not find a decent pic of real 3D so had to put up a pic of one of my model 3D mk2's ..the 4D had the same boom as the 3D but a much bigger dipper, and from experience the 3D was one hell of a digging machine, you had to be careful if you had the kingpost set to the side with a 3ft bucket full of muck not to slew out from the machine, thats one of the reasons why the 4D had the kingpost set in the middle.

I came across this photo of a JCB 4D mk2 taken in late 60's .. shame the guy who took the photo missed out the 22 RB to the right of the picture

The corner of the RB is probably due to the marketing department trying to emphasise that the (then) new, all modern JCB's were pushing out the old technology/methods of the RB, that or the photographer was stood in the wrong place :lol:

I'm sure I've seen on a 4D brochure, a 4D with the small II in red lettering so typical of early JCB livery. Anyone have any ideas what the differences between the original 4D (Mk1 I guess you'd call it) and the 4D MkII?

I've seen a couple of 4D's on eBay over the years, I'd love to see one in the flesh even if it was just standing there in a yard.

Whitlock built a competitor to the JCB 4-series, called the 605. It too was a fixed pivot machine, I think I've seen a picture of one that was on a farm in the Netherlands somewhere. I'll see if I can find that picture, might still have it on a cd somewhere.

Gavin ..there was never a 4D, just the 4D mk2 ..it did have a face lift in 1970 with shorter hydraulic housing,tool box housing and parallel lift arms

There is a brochure saying 4D
JCB 4D MK 2 yellow cab.jpg

But it was the 4D mk2 ..you will notice the II just behind the 4D

Yes thats the very same brochure where I noticed the II.

Is there a definite number how many 4D's were built, I keep hearing this magical figure of "a couple of hundred" but can anyone say for sure just how many were made before production ceased?

I thought seeing 2 of them on eBay was quite remarkable, seeing one in the flesh would be spectacular.
