Having purchased a wheelbarrow some years ago of the rather standard design, I never liked it. The design is an "A" frame of 2x2-ish lumber attached to the metal "bucket" area. Ahead of the tire the 2x2's are tied together with a metal cross brace. The problem with the design is that this cross brace is too low and too likely to snag on the ground, especially if the ground is uneven.
A few days ago I finally decided to saw that "nose piece" off, so I did and the result seems quite adequate, and MUCH LESS ANNOYING. If I ever decide to add strengthening perhaps I'll build a brace above the tire or add angle iron to the bottom of the wooden frame, but I doubt that will be necessary.
