I have a M4800 that has a new aftermarket hydraulic system that was added by the Kubota dealership. It has worked for the past few years with a 7' Kodiak Cutter. No other hydraulic implements on farm. I replaced the 14' hydraulic line but it doesn't move the cutter. The hydraulic fluid is full and the line appears to fit right. Does it have to be primed or any suggestions would be appreciated.
