Interesting all round, I was most interested in if the 4 equal sized wheels would provide a more powerful front end tool able to work somewhat closer to the performance of a Drott without the huge costs & lack of mobility tracks involve. One thing that is said by the Italians is with the artics, the front bucket follows the cross angle of the ground under the front wheels rather than the rear ones, making levelling / grading in a confined space easier,
but they do find the AWS ridged machines more stable in use. Palazzani & Venieri offer both platforms in a size range. I did find these tyres on the net, being an alternative possibility on ground that would likely cause many punctures solidcushiontires.com/flat-proof-tires/ Maybe on an extra 'spare' set of rims??
There are many narrow lanes round here where a lorry cannot access to unload bricks/materials direct to site, so a small self mobilizing machine capable of handling a full pallet of bricks on the front forks may be attractive to 'Joe Bloggs Builder' as against a mini digger. To be honest the only thing the weirder makes have over the 2CX is a little more road speed, 25mph as opposed to 21.5. The downsides are more complexity, no aftermarket parts. (For instance this firm - was Saville tractors,
www.diggerparts.net/about-us/ is near me, as is Interpart - I dealt happily with the latter firm over the years)
The Italians offer something in between the 2CX & 3CX @ about 7 tonnes & 6ft 8in wide. They go smaller but you lose the good road speed.
The 3CX Compact (really a 2CX but with Bosh Rexroth Shift on Fly hystat trans) is 25 mph - but more complex & first built Sept 2015 - so too 'new' at present cash wise.
It really comes down to investing either in a costly tow vehicle & trailer before you pay for a 2.5t max mini digger
or putting all the money into a self mobilising machine that may earn you more & have fewer competitors. As to the guy who needs a Drott? well he would have to buy this himself - do the job & move it on as this is no tool for a one man band - I did wonder if there was a halfway house machine that may satisfy both needs. I have only ever seen one 4CX - it belonged to an electricity utility & was adapted to carry poles with a frame over the cab, really too big for where I may find a customer base
Firms like 'Triple Crest Planing' have used 2CX's for years - so they cannot be all bad - as to the 25 mph - it sounds slow but watching my van speedo it is amazing how much time traffic is moving at under 30 locally!
Venieri do have a dealer near me (RVH Pugh) he is new to the make but presumably understands hydrostatics? & Venieri do seem to be the market leader of the smaller Italian machines. The others have no UK presence. Looked at Huddig as far as I can tell they are fixed centre post hoe.
