1711 Heart Transplant
3 Attachment(s)
Well, long story short the KT17 Series II in my 1711 went from a beautiful runner to...ventilated on the right side of the block. Well maintained, lasted 850 hours. Reluctant to put in another Kohler, nonetheless I have settled on a CH18S with 250 hours as a donor. Looking for 16-18 horse Briggs for a week or so on Craigslist and Marketplace largely brought up Vanguards for (new) short block prices or I/C units without enough capacity for an electric PTO.
I was most surprised how few horizontal shafts are on the market compared to vertical. Tangent aside, it looks like it should fit readily; I pulled out the KT17 Series II today, will get everything cleaned up in the next week or two and go from there. Looks like my biggest challenge will be thinning down the electrical to keep with the same controls: for example the "new" mower's PTO switch has 6 wires coming out of it. :BlahBlah: |
What is your donor engine from? My KT PTO fit my Command without issue, but it was a Cub spec engine (2185 I think) to start with, and I don't recall any wiring changes regarding the PTO itself.
Quick edit: I did a Command swap on my red 782 2 years ago- |
One major wiring difference will be the addition of a kill circuit for your magneto fired CH-18 versus the points/coil KT-17. You will need a different ignition switch from a 1811 model tractor.
I have become very good at pulling Kohlers from these to fix or replace different issues. I found an excellent replacement M-18 engine to replace my governor-less M-18, my second tractor lost all of its flywheel magnets, so I replaced the flywheel, and my third tractor needed a new crank pilot bushing and magneto, so it too had to be pulled. |

I went with an 1811 ignition switch and modified the wiring instead of the harness swap, but 1711 harness I'm sure will be different than my older 782 harness.
Roland was able to help me with a wiring diagram after providing him the serial of my tractor and the engine. |

I'll have to keep an eye on this topic. I've got a CH18 from an 1864 waiting to go in my 682. I would like to use an 1810/1811 ignition switch as well.

I'd assume the "oil sentry" would kill if it loses pressure anyhow? |
