Tim Lamb used his keyboard to write :
My rideon mower struggles with collecting wettish grass.

Rather than mulching (which creates lines of finely chopped grass and
eventual sward damage) I now mow and go back next day when it collects
happily.

Rare is the time when mine will collect it, it would need a few weeks
of drought. Even when not collecting, it (and its predecessor) have
always choked up their duct heading to the bag at the rear. The duct
goes over the back axle.

I now drive it around with a stick, so when it does choke up, which is
often - I can just stop it, jump off and poke it clear then carry on.
