Kohler: Craftsman LT2000 Kohler 17.5hp Motor - Trouble Idling, Power Issues

Wed, 15 Oct 2025 17:13:42 -0700

So can anyone diagnose what may be the problem with this mower? I inherited it and the previous owner reported it was very hard to start and took 10-15 minutes of cranking before it would catch. I took apart the carburetor and cleaned that real well, replaced the spark plug. It drives around ok but when at the top of a small hill started losing power and nearly stalled out. When I finally got it to start it was very loud and just my opinion sounded like what I think is a timing problem, but I apologize for the vague question I’m not sure where to start. Can someone tell me if that’s a good guess, how to fix it, and what other things I might look for if that’s not the problem?

Kohler: Engine will run for 2-5 minutes then die

Sat, 21 Jun 2025 10:33:57 -0700

Engine on Kohler powered tractor will start and run for 2-5 minutes then die. It will not crank for 5-10 minutes. After waiting a bit it will crank and then do same. It does this regardless of outside or engine temps. I have run a jump wire to fuel solenoid to rule out the silenoid stopping fuel at float bowl. I've replaced the air filter and checked all fuel lines for crimps. The fuel pump seems to be working also as i can see fuel flow thru the clear housing of fuel filter and it maintains a constant fuel level. I'm stumped.

I have a cub cadet lt1050. It's been having problems starting so I replaced the battery and it worked for a while then it started having problems again and I would hammer on the starter to get it going. Now it won’t start no matter what I do. Ive tried jumping the selnoid and it still just clicks. What should I try next?

Kohler: 1998 craftsman 19.5 turbo cooled won’t go forward or reverse

Fri, 09 Jun 2023 00:43:29 -0700

Please help my mower will not move, it’s a 1998 craftsmen 42in. It stays in neutral. I have done some checking and it has both keys in the drive tires. However, after removing the back plate and looking over the drive belt is good the only thing i noticed is there is a rod on the right side that when pushed the wheels move. I did some further digging and on the shifter there is a spring that is freely there and I assume it’s the issue except I cannot seem to find where it belongs?

Kohler: No spark, lots of new parts

Mon, 10 May 2021 20:09:36 -0700

Here is my dilemma. I have a kohler cv18 command pro that has no spark. I have replaced the master wire harness (because is was butchered when I bought it), engine relay, coils, plugs, stator & the battery. I can’t figure it out. The only thing I haven’t tried is replacing the starter.

Kohler: Cub cadet xt2 will not start

Mon, 07 Sep 2020 15:13:02 -0700

Every time I try to start it the engine turns over once or twice then nothing happens. I have tried a new battery and starter. I have also bypassed the solenoid and made sure there was a good ground but nothing seems to work. Any suggestions would be helpful.

Kohler: Retrofitting Briggs With Kohler Engine

Sun, 30 Aug 2020 09:07:08 -0700

I am retrofitting my old garden tractor with a new 7000 series Kohler engine (KT715-3047). I have two questions.

Looking at the wiring diagrams I am stumped as to where the orange lead goes. The wire marked S on the engine connector has two orange wires that double back onto each other and attach to the same connector pin on the Kohler connector. I have no idea what tractor wire this pin is supposed to connect to.

Also I have a three prong starter solenoid (2 posts/1 tang). I have a Kohler engine lead tabled to to attach directly to the solenoid. Do I need a 4 prong solenoid (2 posts/2 tangs) or can I slice the blue lead into the existing solenoid tang.

Kohler: Why are blades not engaging after replacing PTO switch?

Fri, 02 Aug 2019 19:36:12 -0700

Belt appears to be loose…but no response when pto switch is on. Know that blades will not engage if belt is off…but shouldn't there be some response or noise when switch is on?

Kohler: Why is my mower not wanting to engage the blades right?

Tue, 25 Jun 2019 13:16:45 -0700

2013 cub cadet 1050. When I engage the mower deck it wants to sputter to a stop. If I mess with the throttle a little it will come on and mow perfectly. Sometimes it just does its little sputtering fit and will engage. New belt, spindles, blades, and fuel filter.

Kohler: Transmission /hydro static not engaging.

Cubcadet LTX1045 . Transmission will not go forward or reverse .

The lever in the back that you pull in order to push the mower. Doesn't matter if it's pulled or not I can still push it. So I checked and it's hooked up and the other linkage is all in place. Drive belt is almost new.
