LADIES AND GENTLEMEN, REV YOUR ENGINES!

LET'S SAY YOU ARE DOING LOADER WORK WITH YOUR YT347 OR 359.....
Keeping the engine RPMS at the desired level keeps the lift & lower functions, bucket dump, and return actions on your front loader prompt and responsive to make the job go quickly and comfortably.

Throttle Boost can also help when you need to maintain the power to the wheels.  For example; you need to drive the loader bucket into the material you are trying to scoop, without stalling the engine.

Yanmar YT3 Series tractor come with a standard THROTTLE BOOST feature. The Throttle Boost control button is conveniently located on the loader joystick so you don’t have to move your hand from the joystick control to increase the engine RPMS when needed.

Often, when you are doing loader work you are in a limited space such as a hay shed, horse or cattle barn, or doing construction/landscaping work close to buildings and other obstacles. You definitely don’t want to increase your travel speed by boosting your engine RPM in these areas; you don’t want to have to rebuild that barn or gazebo!

KEEP THIS IN MIND:
When operating a Yanmar YT3 series tractor, avoid performing loader work with the range shift lever in the 3rd speed range position. When the range shift lever is at 3, Throttle Boost is turned off. Throttle Boost is only active when the range shift lever is in the 1st and 2nd speed range positions.
Also, remember that the Throttle Boost engine RPMs will not exceed the maximum RPM setting for the A/B mode settings you are simultaneously using.
