1. To engage/disengage hydraulic pump
2. To engage (540/1000) landrive & neutral for the PTO
3. To shift between high & low torque multiplier under load without using the clutch.

Hi and thanks!
My problem is that suddenly the hydraulic does not work.

1.How should the stick/shaft be turned to engage the hydraulic pump?
Forward or backwards?

3. What is "torque multiplier"? I do not understand the english expression. Could you please explain in words? When is it used?

Thanks, Hans, Sweden

hallo, torqe amplifer betyr momentforsterker. dvs du kan gire ned og opp traktoren et halvt gir uten bruke kltsjen bare ved og flytte spaken fremover eller bakover.jeg har ogs en 8011 s du kan godt sende meg en privat mail hvis det er noe du lurer p!! Skal helst skrive p engelsk p disse sidene

Sorry the language Renze, but i think its ok to help people???.
I just tried to explaine what a torque amplifer is.

Per Olav, i only have trouble when people do not use English on the forum, out of lazyness..
In this case it was necessary

Actually i do know what you said to him, because our languages are of the same Germanic language family.. when you say momentforstarker, and klutsjen, i know exactly what you're talking about
