Have a look on gumtree for shredders. You may pick up one cheap, or now its end of season, the sheds(A & Z et al ) will be reducing them
Getting the bits small is essential. You can use a rotary mower, but a shredder does a better job. I use builders bags for the first heat up. Put all your shredding in and mix in all the grass clippings. That heats up, and may go a bit dry. Then mix in the next lot of grass clippings. It often heats up again at this point. I then shovel it all into a bin to mature. If its a bit dry, turn the hosepipe on it. Let the worms play around in it for a month or three.
If its still a bit chunky, use it as mulch. Worms take down the fine stuff in to the soil, leaving chunks on the surface as mulch.
