A broadcast spreader is a convenient tool to use when spreading fertiliser or seed on your lawn. A common problem with broadcast spreaders is having the wheels lock up. Broadcast spreaders use two wheels: one turns the axle and the other is a free wheel. The axle rotates a gear that operates the spreader plate. Fixing the wheels on a broadcast spreader does not require adjusting the wheels. It requires adjusting the shaft support plate between the axle and the spreader.
Turn the broadcast spreader upside down so that the wheels are pointing up. Remove the screws securing the cover over the support plate with a Phillips-head screwdriver, if your spreader uses a cover.
Loosen the nuts securing the support plate to the bottom of the spreader with a socket wrench. Loosen the nuts just enough that you can move the plate by tapping on it, but not so loose that the plate moves without effort.
Tap the edge of the support plate with a hammer just enough to move the plate no more than 1/8 inch. Rotate the drive tire by hand and feel how freely the wheel and axle move.
Continue making small 1/8 inch adjustments to the support plate until the wheels and axle move with little effort.
Use a socket wrench to tighten the nuts that secure the support plate.
Although this is the general way to free up the wheels on a broadcast spreader, consult your owner's manual for specifics for your brand.
