I’d be tempted to check the metering unit isn’t binding anywhere before splashing out on a motor. Did a bit of work on a pronto years ago that had dodgy metering unit and was pulling to many amps. If I remember right it was just a case of cleaning out the unit properly and making sure everything was free. The power supply connection had been getting hot as well due to the increased load and needed replacing.
our co4 threw a wobly last night , we think we know what it is but wanted to run it past a horsch enginer before we spent a fortune but heis not returning the call. really want to be ready to go after this rain pass's.
If it has the agtron modules at the front, under the tank, make sure that nothing has rattled loose, mine did and i had the same problem.
Sorrow to ask the obvious, but do you have the correct roller fitted for the required output at the expected forward speed range?, also, is it showing the usual rotations of the shaft that you would expect for 250kg/ha at whatever speed you are doing?, does the shaft appear to be constant in it's rpm at an even forward speed? Yesterday, drilling at 190kg/ha, with the black fluted roller, the screen showed it was rotating around the 40 or 41 rpm at a constant-ish 10 kph. (I don't usually pay much attention to the shaft speed monitor on the screen as I need my glasses to read it, but I did have my glasses with me yesterday).

180kg/ha at 13kph is about (60 to 65 revolutions . Memory going.hazy) and draws about 2.9 to 3.2 amps on sprinter 4m here this week. Black fluted roller used on wheat.
Is there any chance the control box thinks its a 'narrower' drill ie 3m not a 4m therefore your needing to trick it to put more on and spin the motor fasterThanks. That tallies in fairly well with what I've got going on.
180kg/ha at 63rpm is 2.86kg/rpm
My 260kg/ha (seeding) at 85rpm is 3.06kg/rpm.
Not a million miles away from one another given the potential 1kph speed difference etc.
It just makes little sense that I need to tell the computer 400kg/ha to make it do 260kg/ha. I'm going to assume that it has a shaft speed sensor somewhere in the motor counting the revs.
Not sealed on 4m machines.Make sure that the seed bin door is air tight. If it is leaking air the seed rate goes down.
Is the speed sensor the one which goes into the back of the seeding meter on the left of the picture?View attachment 1141917
