A new entry-level mounted sprayer - the Alto - and a
"greeneræ and more convenient plumbing installation for the Racer
trailed sprayer are among developments in theBerthoudrange.
The Alto replacement for the Pulvasol comes in 300 to 800-litre
sizes with 7m to 12m manually folding booms and optional hydraulic
lift.
Unlike the sprayer it replaces, the newcomer features an
integrated clean water supply that can be used to flush the
spraylines without diluting the tank contents. It also benefits
from the addition of a high pressure filter and a venturi to
increase self-filling capacity.
Manual valves and a basic pressure set system are standard but
Martin Shackcloth of Berthoud UK thinks British buyers are more
likely to go for the electric control package, which provides
automatic pressure compensation for changes in ground speed within
any gear.
Installing Dualmatic multi-port valve plumbing on Berthoud's
mid-range trailed sprayer to create the
Racer EX not
only brings the machine up to date in terms of control convenience
but also significantly reduces the machine's residual liquid
volume.
First introduced on the higher-specification
Tenor sprayer
two years ago, Dualmatic replaces as many as seven individual taps
and attendant pipes with two close-coupled multi-port valves.
Selecting different functions is said to be almost foolproof
because there are just two handles to set three markers indicating
that a particular function has been set up. The reduction in
pipework minimises the quantity of spray solution remaining in the
system when spraying has finished.
Dualmatic has been further developed for the
Raptor
self-propelled and Tenor trailed sprayers by fitting actuators and
an electric control system. All the operator has to do is select a
function on either of the two control panels - one mounted on the
sprayer, the other in the cab - and the system's "brainæ works out
the required combination of valve ports.
