Heres a few pictures and measurements. The deck is 5.5 " deep. The blades are about .25 inches from the internal baffles. The front of the internal baffle is only 4" as it tapers down in the front to let grass stand up I assume. It's about 4" from the front baffle to the front of the deck. You can see where the front baffle tapers to a shorter lenth up front. If you need more measurements let me know. This was kind of a quickie job not knowing exactly what you were looking for.
