OK - I was in 2 minds as to wether to post this - but hey ho, I's man enough (Shush all those that know me )
Underneath where the centre front seat or cubby box sits is a plate, like the battery cover plate under the passenger seat, underneath this sits a switch, very similar to a hand break switch. When the PTO leaver is engaged this presses the switch and activates the alarm buzzer and warning light - it is at this point my engine would stall.
On the wing top next to the winch controls is an emergancy engine stop button... I guess you can see what's coming...
Whenever I've tried the emergancy stop button in the past it has not done anything and so presumed it to be not working and added it to the to do list. The red knob was broken and a friend removed it with the intention of taking it to work to see if he could "find" a replacement, this just left the thread of the switch showing.
Needles to say, over the weekend I found out that this cut off switch only works when the PTO is engaged, and someone had depressed it, with little or no visble sign of this, I's spent several weeks trying to work out why my engine stalls when PTO is engaged.
Hence, there is now an old gear knob on my wing top where otherwise a big red button should be, and all's well with the world.
Thanks to all for your help.
