DT12-V Vocational Transmission
Gearing A wider overall ratio for improved startability and low speed maneuverability with a new planetary gear set design for greater input torque and GCW limits with improved durability.
Rock-Free Mode Staying in drive and using the accelerator pedal gives the ability to break free from wheel-stuck situations and related downtime.
Off-Road Mode Specifically designed to take on off-road driving conditions with optimized shift maps for extreme road conditions.
Paver Mode The DT12-V enables a constant flow to paving machines by shifting from Neutral to Drive without depressing the brake pedal.
Bottom PTO The DT12-V’s bottom PTO provides dependable performance and, when combined with the rear PTO, offers dual PTO usage that further increases job flexibility and application coverage.
Power Launch Automatically increases engine speed up to 1,200 RPM during launch for smooth, powerful takeoffs with heavy loads while protecting the clutch and driveline.
