Combines 7720 combine speed

[St]

Hi... we have a 6622 turbo (1980) and in 4th gear, the speedometer reads 13.5 - 14, yet the flager said I was doing near 20 MPH. Anyways, if you've noticed a decrese in other gears, then you might have Hydro problems, but I'm not completely sure.

your bellcrank is worn out. It is at the end of the control cable coming from the cab. When the hole is egged out, the thing wobbles around enough not to get full travel out of the hydro control lever.

We have a 7720 in which we have put an acre meter on in which the acre meter gives the m_ph and the one with the header is about 1_6th slower than what the acre meter says if thats any help to you.
