Get a reducer?

You could use an old rectus 19 fittings , male and female, if you have one. Heat the hose up with hot water, put them on , o clip them, then you can gaffer tape them up to protect them as they go over the ground..
I’ve used different methods over the years. This one works well. Pole hose to reel hose.

Use a 6mm straight connectorWrap  PTF tape round the joining probes warm the hose and use O clips to fasten, cover with tape to protect.
