What is the maximum accuracy variation in seed metering?
As good as 2% variation between rollers
Accuracy can be affected by various factors such as rates, slope, crops, and the use of splitters.
What is the typical accuracy range for seed metering?
Commonly in the 3-4% range @ meter
What effect do 1890 splitters have on accuracy?
Decrease accuracy by 2-3% in most conditions
How does seed metering change displacement?
By changing speed instead of meter exposure (as on box drill)
What is a unique feature of seed metering regarding speed and exposure?
Speed AND exposure are always exactly the same between meter sections
What is the implication of not zeroing out feed cups in seed metering?
No zeroing out feed cups
Fill in the blank: Accuracy in seed metering can be affected by rates, slope, crops, and the use of _______.
splitters
