Is the backhoe loader a thing of the past?

Just watched that and the previous
420k in USA !! Just how do you make that ever osy for itself?
Incidentally then went down the rabbit hole and you can tidy looking used one for 40k in Sweden....🙃😊😍 One day..
I remember talking to the Swedish Steelwrist team about Huddigs, they basically said "they're for companies that don't know thier numbers"

I'd still love a go in one!

Re. poor man's backhoe, a good effort BUT he has failed to address two issues (unless it is only to work on totally flat land) the motor would have a short life because of these. What he needs are two valves from Flowfit that will stack onto the motor port flange & seal between one another with O rings.
First an anti cavitation valve, this needs a third hose from the tank to its extra port. It would be ideal to make a small ball & spring valve to slightly pressurize the main return into the hyd tank to about 7 psi. Tee off the third hose just before this & take to the anti vac / anti cavitation valve port as a make up supply for the valve.
Second issue is momentary pressure spikes, if someone just dropped the lever at speed going downhill, so the second stacked valve is a cross line relief between the two main hoses - set to relive any spike above the general system relief valve (MRV) The motor CLRV just dumps the spike across into whichever hose is returning LP at the time, so needs no extra hoses. (Remember the main block MRV is out of circuit to its ram once the ram type spool closes to neutral) This is a classic case of problems of a motor with likely overrun mechanical forces fed by a ram spool.
(some wheel motors have the anti vac valves built in along with a shaft drain port - so you would only need the bolt on CLRV for spikes)

Other way is to have specified a motor with built in negative brake - must be fed by a true 'motor spool valve' not a ram one. Maybe upstream of the existing block & must contain its own MRV & be capable of 'power beyond / high pressure carry over' to provide a feed to the existing services.

Many small makers have come unstuck with the above problem. The motorization castor as above was common on early Menzi & Kamo spider walkers. Kamo at least went down the third hose & valves route (I drove one in Italy years ago). Sorry if this is dull / anal

Re the beast, I think FAI became part of Komatsu some years ago & made TBL's badged Komatsu even before. Might be an 'orphan machine' with regard to spares. I would guess the hystat drive would be bought in by FAI & someone would specialize in rebuilds if ever needed, would be worth checking before buying. Guess axles would be Farraro as Italian made. Might have to look in Italy for any used parts. Finding parts would not be quick if it broke down. Alternative 2CX / 3CX Compact much more known over here but more costly.

do it as well as you can,but learn to do it better
FAI 360,s were also rebadged as Hymacs in the late Gordon Brown era, 121, 141, 161, 181,191 201 & IIRC a 211
went to look at this 121 many years ago, pre-'Drema purchase

not sure if the 1501 was FAI or not

Great pics of the 121 etc, thanks. I remember several 121B's locally & a 141. No personal experience of them but have driven a 580D - think this was the last of the UK built Hymacs. Think designed & first made in Rhymney but later production in W Mids? after IBH collapse? This was an 84 model, cab moved to left, ISO side lever controls, no pedals except aux / hammer feed. A real step forward from the 580BT I earlier drove. Should really have been more of a success than it was but £ very high (N sea oil) making imports seem cheap, & not much new kit selling anyway. I never got why early Hymac had to have the dipper controlled by pedals - (partic bad in gum boots), & there was an aux circuit on one of the sticks! I was told by an elderly driver of the very original 480 model that the pedals controlled slew - while three individual levers controlled the digging rams (an old USA Deere / Case set up) This seems better as precise hand control is needed when say grading a batter.
580D was mainly used as a hammer carrier & general loading - I never tried deep trench pipelines or anything similar. Demolished a couple of old brick /tile works with it inc all the old kiln blocks, very sound to use

I looked up FAI in a 1999 What Plant book - no reference at all for 180 or 360s or indeed anything. must have been part of Kom by then. The beast may be a FAI 555 or 555B 50 hp & 5.4 t weight. If in GWO I would imagine the centre pivot articulation & 4 equal sized wheels would give a front end performance close to a tracked shovel without all the costs. There are some spares sold in Poland. I am very nearly 65 with a now non driving wife - 10 years ago before the white fuel thing I would have loved to try it. But If I roaded it I would be stranded with no van & no way of getting back. So now only a trailered item for me. Weight wise it is close to the 2CX. Palazanni used to make something very similar. Last man standing is VF Venieri in these
PS the poor mans backhoe is maybe one of these working in video - digging quite heavy clay - maybe ok on a smallholding but inability to dig close to a wall a big drawback - welds a bit ying tong!

Kubota also made a pivot steer backhoe and manitou made an unwieldy thing with a telescopic boom but I think it was 4ws
