VACUMETER™ Hydraulic Requirements
The hydraulic motors used on the VACUMETER
™
are a low flow, high pressure motor and are designed to operate on a closed-center hydraulic system. If an operator attempts to connect a VACUMETER
™
directly to an open-center hydraulic system, the fixed displacement pump in an open center system will send most of the hydraulic oil over the relief valve. This will produce too much heat for most tractor oil coolers to dissipate. Connecting the VACUMETER
™
to an open-center system is not recommended. See your John Deere dealer for more information.
