Maintain 1500 to 2000 RPM when driving uphilltractionExcessive speeds can cause engine to bounce, lose surface when covered in loose materialMaintain smooth steady control when driving
on hard dirtKeep moving when driving though mud, sand or loose
Watch for brake fadeKeep heel on floor to avoid bouncingBe in same gear you would be using to go up hillMaintain rolling friction (don’t lock up brakes)
, shift at bottom prior to starting the climb.st If you think you’ll need to be in 1gear st Always come to a complete stop prior to shifting into 1gear depending on slope st or even
1 nd Should be in 22000 RPM-Maintain 1500
OFF ROAD DRIVING Release spring brakeApply accelerator slowlyEngage Transmission (low gear)Foot on brakestarting on hill -ReShift to neutralStopProlonged stops on a hill
If vehicle starts to slide, steer slightly downhill into the slideKeep a steady line taking path of least resistanceMove slowly and avoid rocks, ruts to maintain traction
Don’t confuse degrees of slope with percentage of slope45 degrees slope would be 100% slope30 degrees slope would be 58% slope
OFF ROAD DRIVING Know limitationsrun would be a 20% gradeExample: 20 feet rise over 100 foot RUNX 100RISEfeet of horizontal runFeet of vertical rise divided by PERCENT OF SLOPERULES
