Brockport Bill 1,660 #1 Posted June 11, 2021 on the Interchangability chart it shows a 42 inch rear discharge # 0542mr04 fitting a 520HC -- but a few years later after 88-89 of course, the 520HC isn't listed - so my question is.... the 90's mower version of 42 inch RD is model 78355 - does that fit to a 520 HC ? I assume same carriage assembly - but not sure about the mule ?? thanks Share this post Link to post Share on other sites
Brockport Bill 1,660 #2 Posted June 11, 2021 as clarification -- i see the chart shows 78350 as distinguished from the 78355 - first is apparently a standard RD and the other is recycler RD - don't understand how that would change the assembly carriage adaptability to HC -- especially since it lists the H as a fit?
