  • Use GUTB when the load pulled requires less than 70 percent of the tractor's power.
  • Engine speed can usually be reduced by 20 or 30 percent below rated engine speed.
  • Don't overload or lug the engine. Visible black smoke is often an indicator of an overloaded diesel engine.
  • Make periodic checks for optimum GUTB settings. Work for a short time at desired speed and throttle setting. Then quickly open the throttle. If the engine easily speeds up, the setting is suitable. If the engine does not respond, shift down a gear or increase the engine speed. Perform the check again and adjust as required.
  • Remember that GUTB also reduces PTO speed and reaction time for tractor hydraulics.
