If it's been doing this since new, I think it's the pressure relief valve bypassing when it's not spraying.

How could better filtering of air void a warranty or be an EPA violation, considering that Kawasaki sells the same air filtering system on the FX engine models??

Have you read your owner's manual about the first and subsequent oil changes? I'd follow it. If you for some reason didn't get one, let me know and I'll tell you what mine says.

No.

You might have partially sheared the flywheel key. If so, not a big deal.

Since your mower is only a few months old, you might want to talk your cutting issue over with the dealer who sold it to you. Has it always cut like this or did the problem just begin? If it's always been like this, I'd suspect it was never set up correctly by the dealer. If it just started...

Engines that are not warmed up are more prone to do that. When the load is applied, the governor detects the decrease in rpm from the applied load and opens the throttle to bring the rpm back up. But that creates a lean condition and if not corrected with the choke, the engine will die. Two...

I'm guessing the number of plugs I've installed is in the high hundreds, if not thousands. You'd think if installing plugs with anti-seize on them would cause problems, it would have shown up by now. But it hasn't.

Go look on the Kubota website.

Just my opinion, if you're only mowing your own yard, you don't need a commercial mower. What would be nice, though, is to move up to one with suspension or at least a pivoting front axle. On rough ground, rigid frame zero turns often will have no traction on the wheel you want to drive. But...

Hard to answer without knowing what your application is.

I've never used oil but have used anti-seize. Don't know if it helps but so far has not hurt anything, either. 15-18 ft-lb is about what I put on them, if that, using my un-calibrated hand and a 3/8" ratchet to compress the gasket. Have never had one come loose or stripped a thread, either.

Have you tried bleeding the suspect hydro?

When the blades are aligned parallel with the front to back axis of the mower, the front of the blade should be lower than the rear. Your manual, when you get it, should tell you how much. The blades should be the same when checked left to right.

Fram got a bad reputation from being counterfeited. The Fram filters were targeted by counterfeiters because Fram was one of the best selling brands. Fram certainly had the capability to make good filters because they'd done it in the past. I guess what I'm getting at is I wouldn't worry...

Is the new Kaw going to have an air filter as good as your old one?

I got to paragraph 2 and quit reading this. It sounds just like the old hogwash that if you use handloaded ammunition in your gun and have to use it to stop a criminal from doing harm to you or your family, YOU will be the one going to jail. For one thing, is a person who buys a used two-cycle...

According to its SDS, it looks like the miracle ingredients in Seafoam are 'Petroleum distillates' (kerosene) and isopropanol (isopropyl alcohol).

One thing you can do to prevent overheating is to keep the cylinder fins clean.

It can get expensive to throw parts at a Kubota diesel. Do a search on here for another diesel Grasshopper that had similar problems and it turned out to be grass clippings in the fuel tank.

I'd like to hear an explanation of how dirt and sawdust gets sucked into the engine through the exhaust.

Most tractors now sell for less than they did thirty years ago. That should raise a red flag as to what kind of quality you'll be getting. In a time in which the dollar buys far less than what it did thirty years ago, how can this possibly be? Answer is, it can't. I have a 1994 Cub Cadet...

Please tell us which model Grasshopper you're asking about.

Does the fuel line come out the top of the fuel tank? If so, it may have a leak about halfway down inside the tank.

'In line' means anywhere in the fuel line between the fuel tank and carburetor. I'm not recommending this place, just using it for a picture of an inline fuel filter.

Does it have an in-line fuel filter?

I wish I could help you with the adjustment but I'm not familiar with your mower. I should have said "Your clutch might be dragging" instead of "Clutch is dragging." That made it sound like I know exactly what's wrong but I don't. Your mower has the symptoms of a dragging clutch. If you...

Are you sure you have a 42" deck? This doesn't list one for the 2160. https://www.manualslib.com/manual/107899/Cub-Cadet-2160.html?page=52#manual

Clutch is dragging. Is it out of adjustment?

New engines are a lot of money. New mowers are even more. Compare the cost of a new engine against the cost of a new mower of equal capability. If the rest of the mower is in good shape and a replacement engine is available, that might be the best way to go.

I've got one. Had it since new, about 1984. It has a huge amount of endplay in the crankshaft and knocks like it's going to fly apart.

Great post!

Sounds like a worn intake valve guide or valve seal.

If you have the skill, tools and time to do the repair yourself, why wouldn't you?

There are several safety switches that prevent the engine from starting and the mower clutch from engaging. Typically they are on the seat, parking brake, and blade clutch. All of these have to be satisfied to start the engine and activate the mower.

My apologies for calling Profile Posts Personal Messages. My mistake. Now that we've identified the correct title for the method of communication, I reiterate my request that people should use the forums, not Profile Posts, to ask or answer questions, so that more people will see and possibly...

I've got one but mine's the MZ 52. The only thing I've wished for so far is a better air cleaner.

Do me a favor, Star Tech. See that 'New' button to the right of the 'Photos' button on the top of the page? Click on it. You should see 'Latest Posts.' If you scroll down further, you should see 'Latest Profile Posts.' Let me know what you see.

Starting to see more and more of this, again. Please ask or answer questions in the forum for the relevant brand. As Bert said, it defeats the purpose of a forum by using PM's.

Correct spark plug?

A surging engine and not responding to mixture screw changes can be caused by an intake manifold leak.

You're probably setting the piston at the 'wrong' TDC. There are two--one, at which both valves are completely closed and have clearance between valve stems and rocker; and two; the other TDC in which the exhaust valve is almost closed and the intake valve is just starting to open. #1 is the...

Is it really necessary? I don't think so. My 'cleaning' consists of throwing them away.

That last bullet cannot possibly be correct if comparing synthetic vs. dino oil.

If the fuel line comes out the top of the tank, I suspect the fuel line inside the tank has a hole in it.

I used to think that, too, until they took the zinc out to accomodate catalytic converters. Some oils that meet API ratings don't meet some manufacturers ratings anymore. Mobil Delvac is one.

In your case, since the mower is brand new and you admit you're not good at reading wiring diagrams, taking it back to the dealer and letting them correct the faults seems like a good idea.
