I like the wheelbarrow lineup you have. I have one too. I picked up 1/2 dozen wheelbarrows from the various neighbors when we have neighborhood cleanups and the county picks up piles of trash from the street. Many people toss them out when the tire goes flat and they can't figure out how to fix it.
I also got from my work a Radio Flyer wagon, a dumping plastic tub wagon, and a 4 wheeled cart that folds up but will hold 2 large wheelbarrow loads. All for free!
I like to have more than one tool to move heavy objects. I'll sometimes be moving something heavy/bulky and need to move something else to put my first load there. The extra tools are handy. I also have 1/2 dozen ladders so I don't have to keep moving the one around, and 4 different hand trucks and assorted dollys for engines/transmissions/ transfercases/etc.
All were free. I even found one appliance moving dolly/hand truck in the middle of an intersection. While waiting for a light to change, I loaded it in the truck and took it home.
Tools are my friends!! Can you
ever have too many tools?
