Kohler Series II 19HP PTO

Hi all,
I have a Kohler KT 19HP series II fitted to my Ariens (in place of the old 18HP). The engine is missing the front PTO clutch (basically a bare shaft comes out of the front engine stop plate). Can anyone tell me the correct part number or a suitable OEM equivalent so I can finish my tractor

Many thanks

We need the model number of the engine and mower to help. Did you transfer the front shaft off the old engine or did it come with the engine? Single pulley PTO or double pulley?

Hi Chuck,
Thanks for the reply, I got the tractor with the motor already fitted, although I have a serial number I don't have a decal plate with the model which is why i'm struggling.

I believe that the shaft is the one that was in the 19HP engine and not transplanted from the old 18hp. from the stickers that are on the motor I can see it is a series two twin power pack but that's it.

The serial number starts 140 so I believe it is a 1984 but again I have no idea.

I measured the output shaft and it appears to be around 28mm or 1 1/8th inch

Looks like the first engine was produced 1987 and last 1995. Now I do not know this for sure. Now back to your problem. I found nothing for a front PTO but once again that does not mean anything. I would guess it was just a pulley attached and not an electric PTO. I can somewhat confirm this with a picture of the front of the engine. This is the manual I found quick and easy.

Hi Chuck,
It is a PTO, it is used to drive the cutting deck. The serial number starts 140 which when I looked it up gave me the date (but there are so many intenet sites with wrong data I don't trust it tbf).

Simon.
We need to know a little more if we are to be of any help
1) what is the model Ariens Mower / snow blower that you are talking about.?
2) is the engine mounted transverse with the pto pointing to the front & the flywheel pointing to the rear ?
3) is the engine mounted for & aft with the PTO shaft sticking out one side ?
4) did it have 2 pulleys on the shaft ?
5) if so was the outer ( blade ) one engaged mechnically or electrically ?

The actual PTO is part of the equipment, not the engine.
Kohler supplied it with either a shaft at both ends or just one shaft.
Ariens decided what size & type of pulleys would be fitted to the shaft.
I have seen these engines fitted with both a mechanical ( cone ) clutch to the impliment drive belt ( it was a rotary hoe ).
Or an electric clutch ( this was a lawn tractor ).

It is an Ariens GT18 with a Kohler 19HP retrofitted, I understand the front PTO drives the lawn cutting deck which is what I want

2) is the engine mounted transverse with the pto pointing to the front & the flywheel pointing to the rear ?

Yes

3) is the engine mounted for & aft with the PTO shaft sticking out one side ?

No, the is a PTO on the front (missing) and a shaft that goes to the rear with a spate PTO for rear attachments

4) did it have 2 pulleys on the shaft ?

Unknown as the front shaft is currently bare after the engine, there is a tensioning pulley underneath and a splined shaft to provide power to the cutting deck

5) if so was the outer ( blade ) one engaged mechnically or electrically ?

It was actuated by a pull switch which appears to be electrical, I don't have much knowledge of this sort if thing but can see wires coming from the back of the pull instead of a cable

Thanks for the help

I trust very little also.

And before you fit it make sure the stop is in place.
The clutch will have a slot or hole in it which goes over a HEAVY bracket of some sort so that it stays still while the pulley rotates.

Chuck has obviously dug out the parts breakdown so if we ask him nicely he will hopefully post the stop pat number as well.

I have an '82 model Ariens GT-17 (931XXX series) with a series 1 KT-17 Kohler. The PTO side of the engine faces forward with an electric clutch with two belts that drive a jackshaft with splined shafts on each end used for driving the mowing deck from the rear facing spline and a snowblower or a broom from the front facing spline. The flywheel side of the engine faces toward the rear of the tractor and has a flywheel mounted shaft that is connected to a drive shaft that goes to the rear of the tractor and drives the hydro pump and an electric clutch that operates a splined rear PTO shaft for a rotary tiller. The tractor is in great shape with only about 600 hrs on it but the mowing deck is worn out and have no need for a snowblower in Alabama. Have looked for several years to find a new or used mowing deck but had no luck.

PTO looks like it connects to a piece of plate steel that sits in between the engine and PTO. I have been looking for the part it attaches too since I posted the other info. Picture of PTO break down.

As it sounds like Simon is missing a lot of the PTO system could you post some photos please.
It looks like the Bolens Durotrac, latter troy Buit GTX series and the Ariens GT-17 are all same design and most likely all built at the same factory.
If Simons Ariens is missing all of the PTO arangement then he has a lot of work to do as nearly all of those bits are NLA.
I have a customer with the Troy Built version but alll he buys is parts so I have never had a really close look but it does look identical to the Bolens GX-18 that I do service.

Yes, Ariens has discontinued production of parts for the GT series. The GT design actually started out as a New Holland in the late 1960's which Ariens bought the Garden Tractor line from New Holland in the 1970's. The front jackshaft which drives the mower deck is mounted under the engine and has two belts with an idler arm/pulley arrangement mounted 90 degrees below the engine crankshaft with electric clutch on the engine crankshaft. The jackshaft is mounted in a tube with splines on each end and a two groove pulley mounted forward of the front axel. You had to remove the front axel to replace the bearings in the front jackshaft. Later on, they had some Gravely models that were based on the GT series. In the early models you could get a manual trans made by Vickers or a hydo made by Sundstrand. Both with a Dana rear axel.

Yep sounds exactly the same.
Contrary to what a lot of people think most mowers are either built in single type factories or assembled from the same components from the same supplier.
When I started digging around for obsolete parts it became obvious particularly when I started to learn how to decode model & serial numbers.
Murray had paint codes for 42 different brands, Noma had finish codes for 17 different brands and both of these lists included a lot of what Joe public would see as competitors machines.

From what I have seen of this type of mower what you said sounds about right, they do look like variations of a real sub compact tractor.
The Bolens I service has an Eatons tranny and diff that would be at home in a 40Hp farm tractor.
