TD 60 engine. Some time soon i will try to make such a video.

[@Beosaw]

djmaskin Great, TD 60!!! Sounds good, will wait for. Very good tractors this 800 series. Rare here in germany but often to find in the near netherlands. They are often used for farmpulling. Very strong!

Whats that whistling sound in between gear changes called ?

Blow off valve

[@2optima222]

Lauri Määttänen Blow off valve on a diesel..? That's called "turbo surge". The sound you hear (tjoohoo) is the air bouncing back to the impeller in the turbo and slowing it down, with a b.o.w you releace the pressure (phyyycch) when you let of the gas to prevent the air to bounce and keep the turbo spinning. A diesel dont have a throttle body, it's strait open in to the engine. So at low rpm and low boost the engine is "swallowing" the boost/air but at high rpm and boost, the engine cant get rid of it and it is bouncing back.

JohnDeereScania It's called turbo flutter or just flutter.
