I still find the wheelbarrow (it is now 60 YO) a handy tool. With lots of Osage Orange around my place the thorns kept my air filled tires a flat. I tried inner tubes for awhile, but finally settled for the solid tire....and yes....the ride isn't as smooth as the air filled especially on rogh surfaces. BTW it has new handles and some welded seams from much wear..plus a paint job.... Us old Irish geezers grew up with wheelbarrows pushing uphill...riding downhill ...thru mud...heat...snow...carrying rock, coal, concrete and our little kids for fun.
Cheers,
Mike
