Hello All

Model: XT1

Engine: Kohler 7000 Series 24hp

Cub XT1 50" Shuts Down when PTO is Engaged. It doesn't sputter or anything; the engine just shuts off quick
With Deck removed (no load), the PTO engages just fine. This tractor has just 50 hours on it
Anyone have any good words?

Is this a mechanical PTO or Electric ? If electric I'm thinking you have a short to ground in the PTO circuit

 

[skippymud]

Hi Bertrrr, it's an electric PTO. Will check that out

Could have an issue with the mow in reverse safety system. If the mower thinks it is in reverse, and the reverse mow system isn't working correctly or not engaged could be causing the engine to shutdown.

Running on one cylinder and the load of the PTO kills the engine? That might explain why the PTO works with no deck installed.

 

[skippymud]

Thanks evh. I have checked and both are firing. My next step is to inspect this mow in reverse linkage behind the left rear wheel

So the PTO works with the deck removed.... Have you tried the blades and pulleys on the deck to see if they're all free to rotate?

Hiya GearHead. Yes I have. All three rotate without interruption and the belt is in great condition. The mower has only ~50 hours which is pretty low all together and this is a 2015 model. The thing is in like new condition

Put it all back together.
Start it up and engage PTO at full throttle. Does it kill engine?
If it does remove the deck belt from the PTO pulley.
Start engine and engage PTO. Does engine stay running and PTO pulley spin?
If yes then you have a deck problem as long as there is no issue with engine power.
