SEEDER MAT MCK 2500 SX 

2. General description 

The 

SEEDER MAT MCK 2500 SX 

is a multifunction electronic computer designed to 

be used on pneumatic or mechanical seed drills. 
Its main function is to automatically shut off certain seeding rows in order to a leave a 
non-sown row to be used as a “path” for the subsequent passage of the sprayer. 
In addition, the computer can process the signals arriving at two inputs that can be 
used to control the rotation of the turbine and of the distributor. The computer can be 
programmed to  warn the operator by means of an acoustic alarm or a visual alarm 
when one or both these devices are turning too slow or have stopped (

HOWEVER, 

THE DISTRIBUTOR RPM IS NOT SHOWN ON THE DISPLAY)

. 

During sowing operations the display can show the following readings: 

 

travel speed (km/h) 

 

hectares sown, through 2 independent counters (total and sub-total) 

 

linear distance travelled 

 

turbine RPM 

For information on how to program the alarms see chapter 5 “Programming” on page 
21. 
The  computer  performs  these  functions  by  means  of  the  following  sensors:  an 
inductive speed sensor, which should preferably be installed on the machine’s wheel 
axle; an inductive sensor that measures the turbine RPM; a capacitive sensor to be 
installed  in  the  seed  tank  to  measure  the  seed  level;  a  third  inductive  sensor  to 
measure the distributor RPM; finally a magnetic sensor to be installed on the arm of 
the  row  marker  disc  or  on  the  machine’s  lifting  point  (see  paragraph  5.6)  when 
leaving un-sown “paths” (

tramlines

).
