I'm sure I've said it before when I've seen your pictures but the 802 and 802.4 were decent machines. The 803 from memory was always too heavy from a towing prospective but again decent.
Is the middle one of the 3 bigger machines an 8027 or an 8032
Its an 8027 and was a dud tbh, got it from an expat going back whom I used to do jobs for over here and even drove that machine a bit for him, paint was tatty on the metal parts so resprayed those bits, it was prob the worst mini jcb made imho, was reliable but digging envelope terrible and wouldn't track along without scratting if you were cross track, didn't keep it long but the French loved a JCB as they had a great reputation back then(which has gone unfortunately) so did well on it.
Of the machines in the picture I ran the 806 / 802 / 801 - I bought 2 x 801's and kept the best, selling the other paid for the transport + maybe 1/3rd of the one I kept.
Bought the 802 from the firm I left in the u.k as I drove it from new.
Paid 10k for the 806 and I remember thinking how much money earning potentiel was in that 10k machine when it arrived, it had a inj pump issue, the fellow in u.k who I bought it from (knew him well) paid for the repair and then we had 4 or so pretty trouble free years with it, obviously a very basic machine and not comparable to the wacker et65 but wasn't about netflix ..even a hydr hitch was rare

that one had a manual 3cx hitch and used cheap 3cx buckets, it was all about getting going for minimum outlay.
Liked the simplicity of the machines back then compared to now, when you were new in a foreign country,limited language, in the sticks with no contacts, simple was good.
