High-Low Drive Range (Twin Row Machines Only)

Variable Rate Drive Machines Only: Variable rate drive sprocket may need to be switched from high to low range depending on seed population and seed disk selection. See table below.

Variable Rate Drive Population Rates at 5 MPH Ground Speed
Low Range = Large Diameter Sprocket High Range = Small Diameter Sprocket
	Single Row Population (Seeds Per Acre)				Twin Row Population (Seeds Per Acre)
	Low Range		High Range		Low Range		High Range
Number of Cells in Disk	Minimum	Maximum	Minimum	Maximum	Minimum	Maximum	Minimum	Maximum
30	8000	37 000	21 000	98 000	16 000	74 000	42 000	196 000
40	11 000	49 000	27 000	131 000	22 000	98 000	54 000	262 000
45	12 000	55 000	31 000	147 000	24 000	110 000	62 000	294 000
48	13 000	59 000	33 000	157 000	26 000	118 000	66 000	314 000
50	13 000	61 000	34 000	164 000	26 000	122 000	68 000	328 000
64	17 000	78 000	43 000	210 000	34 000	156 000	86 000	420 000
90	23 000	111 000	61 000	295 000	46 000	222 000	122 000	590 000
108	28 000	133 000	73 000	355 000	56 000	266 000	146 000	710 000
Low Range and High Range sprockets generate population rates that overlap for a given ground speed.
If ground speed is 5 mph or slower and target population is within the low range rates shown in chart, use low range sprocket to avoid low motor speed warning.
