Here in England with our famous unpredictable weather, the grass can often grow lush, so it is normal practice to bag the cuttings. Also we cannot always wait for a dry day to come along so we have to try to keep cutting when its wet. My company favours solid catchers made from reinforced plastic type materials rather than fabric catchers as we find the latter do not fill so well when the grass is damp. Due to the size and type of property we service we tend to mainly use Etesia 18 inch or 21 inch walk behinds - Etesias are manufactured in Europe specifically for collecting damp, lush grass. Do you have these conditions in parts of North America and what types or makes of mower and catcher do you guys use to collect in the wet?
