Kubota ZD326 Bogs Down.

Hi there looking for some good advice.

My Kubota ZD326 with under 140 hours is having some issues.

The mower starts just fine but after that it is all down hill.

If I attempt to drive the mower it begen it run a little rough.

If I attempt to engage the blades and begen to cut grass it bogs way down, mower begins to shake and smokes.

Had this problem last season but not as bad, took it in and it was serviced under warranty. At the time I had my doubts that the problem was fixed. Now I am sure it was not.

Any suggestions on what is wrong and what I can do to fix it?

Thanks!

Your 326 is a Kubota diesel.I'd have to give Kubota a call and find an expert dealer. What did your dealer say it was? Are you still under warranty? Anyway I know it hurts.

Hello MS,

Was told they made an adjustment to the PTO.

I would need to dig up the paperwork to say for sure.

Have not put many hours on since the work was done.

Now its out of warranty and I have a feeling they will not stand behind their "repair".

Will find out tomorrow.

Was told this thing was like a tank and would never need to buy another mower.

When will I learn to stop trusting people. ( ranting )

Anything mechanical can have issues. A ZD326 is a solid ztr. They should fix that....at 140 hours, that's a near new machine. I assume you followed all maintaince schedules on it?

On any work like that...I don't have to dig out the papers, I know exactly where they are. If you don't get satisfaction with the dealer, I'd take that up with Kubota.

Let us know how your issue turns out.

The reason I posted here was in hopes of finding someone that had similar issue and what they did to fix the problem.

Yes. Yes. Yes.
Oil Changes.
Filter Changes.
New Blades.
Grease Fittings.
Ect...

Yes they should fix it but will they? Will see. Will let you know.

my ZD21 with 700 hrs did something similar. would start to run rough under load and bog down. Dealer checked it out and it was the fuel system. they replaced both fuel filters twice and then finally blew the lines out and then it had been fine since. not a hickup since. i love my ZD. Not much can go wrong with one of those, sounds like a fuel problem to me. Good luck!

I was going to say that it sounds like a clogged fuel filter or a dirty airfilter. This fuel today it tough on the carbs and filters. I change all my filters every spring and last summer I was ridding along cutting and the mower just bogged out and shut off, it would start but ran like crap. I changed the fuel filter and blew out the line and off it went? I don't know why, everything was changed and cleaned, but I guess something got stuck in the line.

Will change the filters again and see if that makes a difference.

Shame as the air filter is like new.

I thought new blades every season was bad but if I need new fuel / air filters every season just to cut my grass. Yikes.

Will try blowing out the line as well.

Thanks guys for both of your suggestions. Will let you know what happens.

Should I be using a diesel fuel additive?

Being you have a diesel there ain't a carburetor. But you do have injectors. Yes a diesel fuel additive is in order. I would suggest StarTron.

I would not buy a new air filter if the old one seems clean! I mean you can tell a dirty airfilter that would be suffocating an engine. Like MS said you have a diesel engine and there could be different things going than say a gas mower, could be a clogged injector? I am just wondering why it is smoking? What color is the smoke, Black or white?
