Does the ford tractor 860 diesel have a neutral start switch as used on the 8N and Ford Jubilee?

No diesels in the 800 series tractors. It's either a 8x1 or some sort of transplant.
 
fredstev,
Wrong identity for my friends tractor. May be an 801. The engine looks like the engine in my ford jubilee. The injector pump fits where the distributor fits on my Jubilee.Did a lot of work on the tractor to get it running.
Thanks for the reply

Any pre-1965 4 cylinder Ford 4 cylinder tractor would have had a neutral safety starter switch when it was new. Lots of them have had them bypassed over the years.
 

The safety starter switch (if one can call it a switch) on any non-SOS Ford tractor built prior to 1965, is a mechanical plate that prevents the starter button from being depressed unless the gearshift is in the neutral position.

There is nothing electrical about it. 861 is one of these tractors. If the transmission is in neutral, the starter button can be depressed, thus giving the solenoid engaging coil a ground to complete its circuit and pull the solenoid contacts in.

SOS models, on the other hand, have a safety starter switch under the transmission cover. It completes the solenoid ground circuit only when the SOS transmission is in Park.

The safety part is a plate that keeps the button from being depressed unless the gear selector is in neutral, but the button itself is indeed a switch, and it controls the flow of electricity, so there is indeed something "electrical" about it. The button is the switch that completes the circuit to ground. Why are you saying that the internal switch on an S-O-S is a switch and the button on the manual transmissions is not a switch?

you're reading things into my reply! The plate that prevents the starter button from being depressed has nothing electrical about it! The starter button is just that, a starter button. It's not the part that enables the safety. Whereas, if you knew anything about an SOS, you'd know that it has an electrical switch that that is closed by the shift shaft cam in the transmission when in Park to enable the ground.

The original question was about the "neutral start switch". The button is the switch and it is electrical. The plate is merely the safety lockout that only allows the switch to be activated when the gear shift is in neutral. So there is no "neutral start switch" as a single part. it is a combination of the parts that makes it a "neutral start switch".

My friends tractor is an 861. Due to the "Stay in Place" state of Washington state I am unable to drive the 100 miles to help him. You are correct, My knowledge is limited on an SOS, that is why I asked the question on the forum to learn. The two tractors I have, ford jubilee, ford 8N, both have the safety start switch. I replaced the safety start switch on my jubilee and yes I understand that the switch is allowed to open related to position of the shifter fork. Wasn't my intention to indicate the plate has something to do with making the switch work.
Talked to my friend yesterday and I think his safety switch is faulty. He told me by working the shift lever he was able to get his tractor to start. Transmission is different on his 861 than on my jubilee or ford 8N
Thanks for the reply, have a good day.

Sean,
Thanks
for the reply . Talked to my friend yesterday and his tractor is an 861 ford diesel tractor. The engine looks like the engine in my ford jubilee which is gas. The injector pump on his tractor goes in the place where the distributor goes on
my ford jubilee. Similarity ends here. His 861 develops a lot more power than my jubilee.
Have replaced the start switch on my jubilee.
 
Sean,
Just my lack of explaining correctly with the English language.Probably my lack of understanding regarding the switch Yes, Switch to start on my jubilee, ford 8n, and the 2 n I sold is a switch, electrical.
What I didn't know, does the 861 ford tractor, have a swicth such as on my ford tractors. It is my opinion that the plate is simply a holder for the switch.
 
Your knowledge regarding the 861 starting system is appreciated. Have helped him with his tractor the last couple of years. He called me yesterday and told me nothing happened when he tried to start his tractor. He worked the shifter up and down and the tractor started and continued to start remainder of the day. Told him to start with the battery, check the voltage, then check all the cables for connections.
Thanks, Chris
 
The 861 does not have a Select-O-Speed transmission. It has a 5 speed manual transmission. The shift pattern is different from the 4 speed that you are accustomed to on your 8N, but the neutral safety starter button lockout plate and push button switch operate in pretty much the same way. If he has to wiggle the shifter to find an exact spot where the starter button will work, then the plate itself or something else in the shift linkage is worn.
 
Sean,
Very helpful information. You obviously are familiar with ford tractors
When I got the jar someone had bypassed the neutral start
I replaced the neutral start and it works as ford intended

Bob?s 861 does have a different transmission than our ford jubilee. It
may have some type of low range or the low gear is just extra low
Thanks
Chris
 
The middle digit "6" in the model number tells you exactly what transmission it has. The 801 series of tractors was made up of different models that were specified by the middle digit in the model number as to what transmission, hydraulics and PTO options it had:

811 - S-O-S transmission and lift but nor PTO
821 - 4 speed transmission with no lift and no PTO
831 - 4 speed transmission with lift but no PTO
841 - 4 speed transmission and 540 rpm non-live PTO
851 - 5 speed transmission and 540 rpm non-live PTO
861 - 5 speed transmission and 540 rpm live PTO
871 - S-O-S transmission and single speed 540 rpm independent PTO
881 - S-O-S transmission and dual speed speed 540 and 1000 rpm independent PTO
