BX -- low oil, or low oil pressure engine shutdown?

[keyman1808]

I would be afraid of hauling a load down a steep hill when it would suddenly cut out due to low oil. That could cause the tractor to break away and free wheel. IDN if would want the shut because of this possible scenario

how about this... add a counting circuit when the oil lamp comes on. if the oil light comes on and the timer goes from 5 secs to zero it would trip a saftey switch circuit that is part of seat/hst pedal start/pto on start that in turn will engage the fuel solenoid on the BX engine to shut it off.
One thing to keep in mind, you will need to have a transistor to disable that low oil shutoff feature when the key is in glow plugs position.
this is gonna take a electronic geek to come up with a circuit board for.

A simple solution would be to have a switched relay to activate the shutoff solenoid. A signal from the oil pressure switch could activate the relay that would in turn provide power to the shutoff solenoid. There could be a manual dash switch included for when you don't want the system to be active (such as crossing roads, etc).

I occasionally have my tractor running a PTO generator for my house during power outages. A safety system like this could be good peace of mind. Might even be worth wiring it for high temp protection as well.

Perhaps an audible alarm would be a better idea. Granted there will always be those who can not hear..(me). But with all the safety devices and cut outs in place, it could be a sound that should be heard in the drivers seat, and should make your ears bleed..(not really but close...)......next up cattle prongs...hehe

Mobile equipment usually doesn't have such a shutdown as the machine could stop in a dangerous situation like crossing a road.

X2...rules different for stationary vs mobile...

good point I havent considered..

Look at murphy safety shut downs. I would kill the power to injector pump and electric fuel pump if equipped. Temp senders close at about 220. Oil pressure is open until it builds about 20 psi.

Murphy has dominated this space in the marketplace for many decades.
