Planter Capacity Calculators
Hydraulic Oil Flow Rate Formula (assumes 1:1 gear ratio)
To calculate hydraulic oil flow requirements to select the optimal hydraulic control valve for use with a hydraulic motor, use the following formula:
Hydraulic motor in3/rev x motor RPM required divided by 231
Adjust the cells to calculate the oil GPM required
Hydraulic Motor RPM Formula (assumes 1:1 gear ratio)
To calculate motor RPM required to achieve maximum application rate enter values for pounds per 1 REV, max application rate, ground speed, and spread width.
Adjust the cells to calculate the oil GPM required
Hydraulic Oil Flow Rate Formula (assumes 1:1 gear ratio)
To calculate hydraulic oil flow requirements to select the appropriate hydraulic control valve for use with a hydraulic motor, use the following formula:
Hydraulic motor in3/rev x Motor RPM required divided by 231
Adjust the cells to calculate the oil GPM required
Hydraulic Motor RPM Formula (assumes 1:1 gear ratio)
To calculate motor RPM required to achieve maximum application rate enter values for seeds dropped per 1 REV of planter row unit, max application rate, ground speed, and row spacing.
