Thank you!
Here's what I found;
HRC215 PXA (DIFFERENT AIR FILTER)
HRC215K1
HRC215K1 PDA - MZAU 6100001-9999999 manual transmission
HRC215K1 SDA - MZAU 6100001-9999999 flywheel brake
HRC215K1 SXA - MZAU 6100001-9999999
So I think I got the SXA because no flywheel brake, self-propelled, and after 6100001
