Wheelbarrows are very useful tools for gardeners or any person moving heavy or loose materials from one location to another. They come in a variety of sizes and shapes and each type is designed for a specific type of use. Some have two wheels, but most wheelbarrows used in home gardens have a single wheel. Over time the bucket, if it is metal, will often dent and rust and sometimes develop holes. Plastic buckets are subject to cracking and holes as well. When this type of damage occurs it is time to replace the bucket.
Purchase a replacement bucket that matches the size and shape of your existing wheelbarrow. Take measurements to the garden store since the buckets look alike on the shelf.
Turn your existing wheelbarrow upside down. Loosen and remove the carriage bolts holding the bucket to the wheel frame. Remove two additional carriage bolts to the tray brace or front support if you have them.
Lift the bucket off of the wheel frame and set it aside.
Brush the tray brace and connection points between the bucket and the wheel frame. This is particularly important if there are metal contact points that have developed rust. Use your wire brush to remove any rust. Clean your carriage bolts as well. Wipe off any dust.
Spray any formerly rusted spots on both the wheel frame and bolts with a rust-preventing spray paint and allow the paint to dry 10 to 15 minutes.
Mount your new bucket onto the wheel frame and tray braces using your existing carriage bolts. Tighten down the bolts until the wheelbarrow feels solid and secure when you move it around.
