Summary

• Total system integration of an OBVP solution

provides optimized driveability

• Options are readily available to address mechanical

systems and the transmission PTO

• The OBVP User Interface defines the operator’s

interaction with the system

• TIG based OBVP systems can meet the needs to

fight today’s fight and tomorrow’s
