2016 XT1 Enduro Series 50" dies shortly after engaging blades
 

Hello, all!

I'm new here, but have been reading a lot on these forums. Good info, for sure.

Here's what I have:

Cub Cadet XT1 Enduro Series w/ 50 inch deck (model 13AQA1CQ056)
Engine: Kohler PS-KT735-3058

What I've done:
New Fuel
New gas cap
New fuel filter
New fuel pump and fuel lines
New carb.
New ignition modules
New air filter
New Spark Plugs
New oil filter w/ oil change
New Battery
Also new Spindles, Blades and deck belt.

It runs fine without load, but once I engage PTO (electric) I can mow for a short distance before it dies. It is tough to restart right away, but after a minute, I can start it and drive it back to the garage. It may or may not die while driving it back to the garage. Inconsistent.

This was happening before I swapped out all the stuff above. I can mow for a minute or so longer now than before I changed everything out, but still having the same problem.

Please help. I don't know what else to do, other than lower the mower onto my head to put an end to it all. (kidding, but seriously. I'm at a loss here.)

Thanks!

I have seen clogged gas cap vent holes cause this condition, but since you have a new one you might try mowing with it loose and see what happens.

I would check that you routed the belt correctly after putting spindles in it. Or you could have a bad idler pulley on deck

Just a guess as I know nuttin about the new stuff.
Do you have good fuel flow to the carb or is it fool injection?
could be starving for fuel.
Does it run if you dribble fuel into the carb intake while pto is operating?
worth a check, you have thrown a lot of parts @ it so far!

How would either of these situations make it not want to re-start after it craps out?

I went that route because he also stated it ran fine except for after engaging pto. By runs fine I assume that means runs and drives fine other than when pto is engaged. So that wouldn't really explain a clogged gas cap either. Of course theres not a whole lot of info to go on here either.

I guess we need to ask. Does it run and drive fine with full power and ONLY has this problem after pto engagement?

Maybe the PTO is jamming up and staying engaged making it hard to crank

The clogged gas cap vent scenario I exampled did run fine until started mowing. I guess the extra load of mowing draws more gas. Really didn't discover it until I took the fuel line off after it quit and nothing came out. Took the cap off to check the tank and gas came out all over the place. It also would not start right away, but would start easily after 2-4 minutes.

WOW.. That's good to know.. Hey.. I trust your judgment. That could very well be it then.

Thank you all for chiming in.

Took the gas cap off, but it died after blades were engaged for a minute or two. (Yeah, no trouble driving. Only issues happened when trying to mow.)

Belt is on correctly and all pulleys and wheels are good to go.

So, I had thought, as it really sounded fuel related the whole time. I disconnected the new fuel line from the fuel filter, and blew compressed air up into the tank.

I was able to mow for about 20 minutes before it wanted to die on me again. I think there was some debris in that little spigot the fuel line connects to on the fuel tank. Enough fuel was getting out to allow the engine to run, but not enough to handle a load.

I'm going to pull the tank and clean it out, and I'm betting Ill be good to go. Maybe??

Yeah,, I think your on the right track.

Some of those petcocks in the bottom of the tank have a screen on them.
:biggrin2:
Next time, diagnose the problem first and make yer wallet happy :beerchug:
Good thing is you have a lot of spare parts that will last longer than the mower.

Thanks. I sure hope so.

Ha! Each time I replaced something, I thought I WAS diagnosing the problem. Started with the gas cap, and worked my way through the fuel system. But, hey, I know I'm good now. Learned a little bit on the process, so it ain't all bad.

Not to talk down to you,
but throwing parts @ something is not a diagnostic procedure.
But we all have to learn sometime, you did, and was kind enough to share with others here so they learned also.
And it is good to have spare parts that are known to be good.

You will be surprised @ the chit you will get out of the tank.
Trust me, the blow back you did on the tank is only a temp fix.
Guaranteed it will plug up again the farthest from the workshop possible Ha,LOL :beerchug:

I hear ya.

For the record, I didn't throw parts at the problem. Spindles, deck belt and blades needed to be replaced. Gas cap was clogged (Gas tank collapsing), so I replaced it. Battery was three years old, and not holding a charge, so I replaced that. While I was doing these things, I thought I should change the oil, spark plugs and fuel filter prior to my first mow of the season. After that, I still had the problem I described.

Days of research and multiple info sources pointed to collapsing fuel lines, ignition coils or carburetor. I replaced the fuel pump and lines first since it was less than $20. Replacing the ignition module was cheaper than the carburetor, so I did try that first. Unsuccessful? Yep. Replaced the carb.

I listed all the new items in my original post as a thorough picture of what had been done recently.

So, now I guess I have some spare it ignition modules and a carb. I'm not going to hang on to a $7, three year old fuel pump.

I did learn I need to check each section of the fuel line separately, though. I only checked the line coming from the fuel pump for fuel flow.

Hopefully this will be helpful to others who are learning as they go.

Thanks again!

Scott,

All that matters is that its up and running! :beerchug:

Amen. Superchugs...
