As has been discussed, the box of tricks takes a feed from the alternator to know it's speed probably by sensing the alternator amperage.

 

Probably best checking for loose connections, but if the chipper is charging the battery the stress control box would be my initial guess and or the feed switches and emergency stops.

 

Granted, last Kubota one I repaired had a black sensor next to the flywheel on the starter side of the engine and used SP4 shown in the diagrams.

Iv been trying to find this sensor as I belive it’s a speed sensor 

but I carnt find any images of it and its location on Manuel and internet

The alternator produces three phase alternating current which is rectified using a diode pack to dc. The W terminal is connected to the ac side so produces an ac pulse that is proportional to the rotational speed and so can be used for speed monitoring.

If the drive belts to the flywheel are slack the stress control won’t function properly.

ive had it happen a few times 

they need to be pretty tight

Update guys 

 

after dropping off to a Timberwolf 

approved dealer 

the problem was the plug under the hopper 

had (corroded pins) 

 

 

it’s the same plug I checked for my self I obviously dident know what the bad pins looked like as they all looked the same just a bit of  green discolration 

so it’s been fixed but cost me a nice few quid for some pins in a plug 

😫

 

hope this helps any one eles with this problem 

 

next time I think I’ll try and jump wires over the plug to the other plug wires  to see if that works then get a new plug and wire up again when tested 👌 for the fault

A can of spray contact cleaner can work wonders followed by some wraps of self amalgamating tape.

Yes a school boy mistake I should of tried a spray cleaner  but I tried the old wire brush and it dident do for me 😔
