PTO Help 1975 C160 Auto

[Krice58 24]

Working on getting my grandpas old tractor running and I’m a bit confused. There’s a switch and wiring left for an electric pto clutch, but from what I can gather it looks like it’s been converted to a manual pto. It still has the pto safety switch that comes in contact with the engagement lever, I’m just very confused as to how I’m supposed to wire it because I was going on the assumption it was electric but it doesn’t seem to be. I’ll include pictures to show what I’m talking about. Do I even need the clutch switch on the dash if it’s manual? And what about wiring for seat switch and interlock switch?

Looked at the 1975 ipl and it shows a manual pto.

What is your model number and serial number off the ID plate?

I recall a wiring diagram that showed both the manual and electric pto on the same drawing. It may have been a mid-model year change. Took me a while to figure it out.

Here is the wiring diagram for manual pto which is what the ipl shows.

Click on the tractor in this link. You can also download the wiring in pdf format.

There was a special electric pto dash switch that controlled the starter and ignition as well as the electric pto.

If you have the switch at the manual pto linkage that controls the starter and ignition use that.

I believe this is the electric pto switch back then

This is what the ipl shows for a manual pto switch

Awesome thank you. The more I look at it, I believe it was just a manual pto from the factory. The only thing I can think of is maybe they just used the same dash for multiple models with and without the electric pto and must’ve just plugged the hole for the toggle in the one’s not equipped.

That is correct.  

Wheelhorse was well known for using the same parts long term.  

The early 70's had electric PTO.

@Krice58     You have two posts going asking the same questions about  the same tractor. Have you looked at the responses to your other post?

Whoops. Didn’t mean to start another thread. Yes I did read through that one, it was very helpful, just was thrown off by the electric clutch switch. But I think I got it figured now.

Your PTO is a manual unit, the switch is a part of the safety switching. 104680 as shown by @gwest_ca is the correct switch. See my reply to your other post for wiring information.

I have a 1973 14-8 with a mechanical PTO clutch.  The dash has an unused spot for an electric PTO switch. 

 

Wheel Horse was a thrifty company.  Why have two dashboard part numbers ( electric and non electric PTO) when a 3 cent hole plug can cover up the switch hole when not needed, instead of tooling up and controlling inventory for a second version of the dash.  My opinion, anyhow.

My '76 C-120 has a manual PTO, but also has a spot on the dash panel for a toggle switch for an electric PTO. The hole was filled with a plastic plug. Last night, it became the hole for a toggle switch for flashing lights I added - for working near a busy street.

@953 nut -twas a case of brain fade.  Motor Wheel is where I started my engineering career in the automotive parts supplier industry.  As @gwest_ca points out, there is a Motor Wheel connection to Wheel Horse through REO.  I think that Motor Wheel owned the REO lawn and garden business for a while.

 

In the first few years of my career, I spent many hours in the old REO building for meetings and working with the CMM in the QA lab there.

 

I'll blame the slip up on the heat........
