Rover Mowers Limited Chip `N Shred OPERATION
3.8 Screens
Two screens are supplied with the Chip `N Shred, the
standard screen consisting of numerous holes in acurved
plate and a bar screen consisting of widely spaced bars
between two side plates.
The size of the mulch produced by either shredding or
chipping is dependent on the screen fitted to the Chip `N
Shred
The screen to be used depends on the type of material to be
processed. The standard screen suits most types of material
found in the garden. If moist, pulpy or soggy types of material
are to be processed the bar screen should be fitted to avoid
blockages.
