I never noticed until I uploaded this that they're both from the same company, "TruTemper." The wheelbarrow, we've had for at least 15 years. We've replaced the tire (maybe the whole wheel). The yard cart is only a couple of years old. We've worn out two others, maybe different brands.
We have three little ramps in the yard, for the wheelbarros. When I take the garden cart on them, I teip it over to one wheel. Maybe someday I'll bring photos of the ramps.
