If your clippings are dry you could leave them in the bags.
otherwise tip them out for a day or so to dry a bit more then bag, seal and
leave them, should compost down.
You could always add shredded paper. cardboard etc to the bags with the
grass.
I cut yesterday, more like hay ,will have around 3 trailer loads when it's
dry.
