Just wait, one day soon you will have to Sit or rather Push for a wheelbarrow test to gain your License, then that wheelbarrow itself will also need to be Licensed, Insured, have Garden Emissions Duty added and then MOT'd, after about two years you'll also need a CPC to go along with your Wheelbarrow licence along with a current D4 medical in case you collapse pushing it on your allotment.
On the Plus side your Wheelbarrow GVW (Gross Vehicle Weight) will be reduced to comply with some EU directive or other and also the Wheelbarrow Tachograph Rules will mean that you can only Push it for so long over so many days....so at least your lot will become easier even if your allotment becomes unworkable due to your allotted pushing time being reduced.
