8.0 HYDRAULIC DRIVE
All aircarts equipped with the Raven Viper Pro™ monitoring system have
hydraulically driven meters. These motors have a maximum speed of 113 RPM
and a minimum speed of 2 RPM. Speeds in excess of the maximum may result
in premature wear or failure of the motors. Reducing the rotational speeds of the
motor below 2 RPM may result in erratic metering which may affect the seeding
rate.
Each hydraulic motor requires a flow rate of 1.0 gallons per minute. The
maximum torque output is 26 ft-lbs. The maximum inlet pressure of the hydraulic
motors is 1500 psi. The inlet pressure is regulated by a pressure reducing valve
as mentioned in section 8.1.
