Hi ademan

Here are parts lists and pics ,I'm thinking the Mk4 is a very similar set up and may use the same blade attachment
method.

It looks like there is a plate / hub that holds the side of the blade shaft and the plate/ hub is bolted to the side rail ,I rarely
ever play with reel mowers but might be able to get some MK6 pics if it helps or someone else may know the
Mk 1 more than i do.

Cheers
Max.
