Good Evening, I have a Reekie 5254 S destoner and I am having trouble with the front paddle rotor. As soon as it is lowered to working in the soil it stops and makes a banging noise. To get round this I have raised the rotor to the maximum height to continue with work. As a result I lose soil out the front (sides) as the rotor is not feeding soil up the machine. I have had a look at the drive from the front and looked at slip clutch cant see anything obvious. Any ideas much appreciated.
