Good evening all ok I’m struggling with the 1928 safe track. The chipper doesn’t seem to want to pull in on the feed roller due to it not revving higher than 800rpm it’s been working absolutely fine until today I’ve checked the fuses and a 40amp had blown second one down replaced that checked the roller solenoid and cable tension any help would be much appreciated many thanks Andrew

Hello, 

 

Just seen this. Is it a mk1 with an Isuzu or mk2 with a Kubota?

 

If Kubota you should have an electric throttle. We had one recently with similar symptoms where the ball joint knuckle on the end of the electric throttle solenoid was worn and would "jam out"  not allowing the machine to rev up. If you get someone else to use the throttle buttons / hand throttle make sure the linkages are working fully in / out and the lever on the fuel pump hitting the stop screw.

 

 

The screen speed is flywheel RPM and as you know the stress control won't allow the rollers to work at 800. That wants to be up around 1400 - 1440 when running full speed with no material.
