Mystery Sears Craftsman LT11 riding mower.

Looking for a little clarification on why this mower has the foot controls only on the right side and not the left like most riding mowers do. The owners manuals I have found online all show the foot controls on the left side (see link)

Model Number of lawn tractor: C45960311
Serial Number : 870568A

Anyone know why?
