Timberwolf 125 stress. Control not working

[Tree cutter]

I’ll check the sensor and yes the rollers still turn on low revs

If it's hydraulic feed roller then it could be a faulty valve block or solenoid allowing oil to keep trickling through.

 

When you disconnect the sensor wires do the rollers stop ?

Mine was the same from new under guarantee but they couldn’t fix it.

So under warranty the TW dealers disabled the stress control?

No they keep going?

[GarethM]

What about the solenoid block?.

 

That would be my first thing to check, usually two wires and a single retain nut. I tend to use a test lamp for such situations when scrabbling around fault finding tractor hydraulics.
