Frequently Asked Questions

What is the minimum RPM I should operate my PTO, so that my vehicle will perform Regeneration during PTO mode?
Regeneration in PTO Mode - when a vehicle is being operated in PTO mode and a diesel particulate filter (DPF) regeneration is commanded, the engine must be run at a speed above the minimum speeds listed in the tables in Body Builder Manual, Section 9, Table of Contents / Regeneration in PTO Mode. The minimum speed setting can be affected by ambient temperature and/or altitude.
On Mack mDrive, with PTO engaged while in neutral, and then selecting Drive the PTO stops turning. Why?
Remember that the mDrive is an automated manual transmission with a clutch. With the PTO engaged while in neutral, when selecting Drive, the clutch is released, then the transmission shifts into gear. When the driver takes his foot off the brake pedal and presses the throttle pedal the clutch will reengage and the PTO will start to turn again. The transmission will not shift gears and driver is limited to about 6 MPH.
Our customer chassis has an mDrive and has a need for moving PTO operation. What PTO is recommended?
Transmission mounted PTO’s are primarily used for stand-still operation, with the gearbox in neutral. However it is possible to engage PTO in vehicle speeds up to 6 MPH. If the vehicle is to have a moving PTO operation, an mDrive with a REPTO or FEPTO is recommended.
