I've got a problem trying to understand the hydro adjustment process on the 1650. I know I'm thick headed, so it don't sink in, so I was hoping someone could explain it to me.
Here is what it's doing, or not. With the brake on to start, and the control lever in the N position you can hear that the brakes are holding it back from moving. The conrtol lever is in the N position. After it is started you hear the hydro whine sound, (trying to explain it) then take off the brake and the tractor creaps forward, ever so little. I have to pull the lever back just below the N position to stop the tractor, and it stops the noise.
I know it's the adjustment to the linkage, (I think) and that's where I don't understand.
It says to adjust the cam bracket to eliminate the noise. It talks about using a hammer and punch to adjust the cam bracket downwards to stop the wheels.
Don't understand, anyone explain it to me different?
