I have been trying to track down one of those wheelbarrows with a ball
instead of a wheel as I think it would do less damage to my muddy, clayey
lawn. Since i decided to get one I can't find one anywhere in the local
(North London ) garden centres , or after doing quite a long search on the
net.
Any Ideas??

My ball barrow now needs a new ball as the original one has split sadly.. I think they're great but cannot track down a replacement ball. Fantastic on the allotment.

Have you thought of doing a google search?
