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
