Timberwolf 150 stress control issue

[Jlgriff97]

Recently bought a Timberwolf 150 2006 model, runs well except when I put a larger bit of timber through the streets control

didn't seem to work and the machine conked out.

 

Could somebody help me identify where the sensor is on this model, am I right in thinking it’s not working as also when on minimum revs the rollers still turn.

Someone may have bypassed the stress controller,, in the engine bay on the fly wheel housing there's a black box on do it and look for wires twisted together. Long time since I was told how to bypass it but sure someone will be along and tell us.
