The new ones havn't got the same cross country capability as the 410's and also the one that we have doesnt have side shift forks. I believe there is capability for them but reduces the weight it can lift.
Ive not had much time in either of them as not much need to use them but when i have operated them much prefer the 410 for field of vision and ability to do minor adjustments when loading ie using inner carriage and side shift
I never liked the new JCB initially but when we used them on Op Outload I found they beat the old 410 hands down. With practice a good operator can do the same job in half the time and the reach means no more spooning of pallets onto beds.
As everyone syas the new JCB does take getting used to but after a bit it does have advantages. Operator vision of the forks is a bit restricted but then you get used to it. All ours have side shift so i can see where this would be difficult with out it. Another good thing is its ideal to charge up your mobile phones on ex!!
