I recently saw a post on the Walker Mower Forum on Facebook that someone repaired a catcher. It was cracked on the lower frontend by the lift handles.
A catcher cracks by the lift handles because the catcher shock has broken and the force when dumping stresses the plastic, causing it to crack. This usually happens on the 9.5 and older 10.0.
Did you know that Walker has a kit and two parts that could be used to repair a broken catcher? Kit# 8515-9 goes between the catcher and the catcher support frame. Part# 8515-13 goes on the left and part# 8515-14 goes on the right. These parts and kit sandwich the lower frontend of the catcher and reinforces it along with the lift handles to help secure the plastic.
