Ok , i just had the seed rate go down during the day earlier this year ,wasn’t sure what the problem was, after a few tweaks here and there this cured problem. The metering wheel ran smooth just slipping a little !!
Have you made sure the thumb screws are tight, the metering wheels can slip on the shaft if not, a quick tweet with the pliers doesn’t hurt to make sure.
Thanks for replies. I bought a used machine this year intending to put low disturbance tines on in future but with it breaking back all the time I can’t see how it wouldn’t disturb the top, but maybe if they pull through easier they may be ok. Do the springs weaken with age?
Are the terragrip tines on these machines the same as on a express st bar because on mine they seem to be breaking back all the time. It acts more like a heavy spring tine than deep soil loosener. I’m not really sure if this is how they are meant to work ?
