I have a 2000 Toro Z-Master with the 25 Hp Kohler motor.
I see that the 2001 and 2002 models come with the Donaldson 2 stage air filtration system. I'd like to upgrade to this new unit. I got some part #'s from Toro and it looks like retail price on the fliter kit and the filter minder is going to be about $300.00. Does anyone know of a place to get these parts at less that full retail cost? I'm not paying $300 for a filter kit, I dont care how good it it. I'm not currently having problems with the Kohler unit, just wanting to avoid any future problems. This obviously is a better unit.

Part #'s are
99-4663 Filter kit
99-4664 Filter minder kit

Thanks for the help.

Correct me if I'm wrong, but don't they still use the Nelson air filter system rather than a Donaldson? I am assuming it's the same one I bought for my Yazoo/Kees with the same engine back in 2000. I bought it when it was stock on the 26 EFI and not much else. Back then you had to buy the elbow and filter kit in two pieces. I guess they have started marketing it together now.

Well anyway, I paid $160 for the two pieces back then, so I wouldn't doubt they've gone up in price since. But $300 seems like a Toro price, check the Kohler catalog for a cheaper price.

The part numbers I bought were 24 743 21 (the elbow) and 24 743 22 ( filter assembly) I purchased the Minder thing later on so you have to add that in if you really want it.

P.S. Anyone else reading this with other Kohler engine models, keep in mind you may need a different elbow kit, that one is for the 25.

Keith,

Who's part numbers are those. The Kholer site doesn't list them and the Nelson air site is way confusing. Help please.

Those part numbers are not Kohler .

Kohlers are 24 743 22-S NELSON air cleaner

24 743 20-S for CH18-20
24 743 25-S for CH22
24 743 21-S for CH25

Need #1 and one of the #2's

Captdevo's prices are great on this part.

The filter minder don't bother getting. Waste of money!!


BTW if this filter was $500 it would be weel worth it.

It extends life to your engine!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

You will have one good thing if you put that on a Kohler 25.

You may be able to transfer it to a different engine at a sooner or later date and use the 25 if you buy a boat.

MOW ED, thee is a turbo precleaner available for your 15 Kohler at www.enginaire.com

HarryD, see your local Kawasaki dealer, there is a Nelson heavy duty aircleaner available for the verticle shaft 23 Kawasaki. www.enginaire.com also has a turbo precleaner availalbe for the verticle shaft 19 thru 23 horse Kawasakis.

HarryD,

Hustler has a nice donaldson 3-stage for kawasaki 23 & 25hp.

you'll have to mount it yourself (no bracket designed except for on the Hustler) to add a 3-stage, you also have to re-jet the carb, the carb kit is included, i sell for $160 delivered.

Mow Ed, I read the first sentence of your post and immediately the first thing that popped into my head was almost word for word what you went on to say. Very funny. My thoughts exactly. :laugh:

What, did I miss something? Is there some kind of nasty rumor going around that the 25 hp Kohler is nothing more than a boat anchor?

Have you guys that have had problems with them all talked?

Have you noticed that you all have the same model year, in fact probably the same serial # series.

You could probably do something about that if you got some facts together, something traceable and on paper.

My 25 hp Kohler only has 75 hrs on it but it runs like a top. Is there anything I need to be aware of??? I ask this question cuz I'm about to buy another Toro Z with a 52" deck and a Kohler 25 Command Pro on it.

my 2000 TT has a 25 kohler on it w/ 600+ hrs. and no problems whatsoever.

i put one of those HD air cleaners on last year (175bucks) and i lost power because it is so restrictive.

They might drop your rpm's by about 50, but that is it.

Mine is a 1999 model 25 Kohler, it now has 1592 hours and still runs fine. Some guys had head gasket as well as other problems, especially on ones made prior to 1999.

odin,

kawasaki does have them out for 19, 21, 23 and 25hp verticals now.

some require jets, some complete carbs. kits range from $230 - $440

my spec sheet shows FH680V_AS19 includes different main jets for existing carb kawa part# 99999-7007

i'd make sure he knows that, and changes them!!

BTW......

if anyone would like Kawasaki 3-stage for FH601V, FH641V, FH680V OR FH721V drop me a line with your model and serial #.

they range from $130 - $500....some require re-jetting of your carb, some require new carbs.

all include filters, brackets, mounts, canister and weather hoods.

i have turbinator pre-cleaners for these for an additional $45.

technically a 50rpm drop would mean loss of power. my max rpm is the same but it falls off more quickly in heavy stuff. the HD filter even made starting more difficult. usually it fired up on the first touch of the key, now it takes a few revolutions to fire up.

yes, more restrictive, its twice the filter....it filters more but it also cuts down on airflow.

non the less, i still have it on my mower and will continue to run it because of its superior filtering qualities.

The heavy duty aircleaners do tend to richen up the fuel/air mixture. At a minimum leaner jets are usually required on Kawasaki engines. We sealed up the factory aircleaner housing on a Exmark Lazer Z 23 Kaw and added a turbo precleaner to the air horn earlier this year. The mixture got very rich and the engine was stumbling on any kind of throttle increase by the governor.

Thanks to all who replied.

I got the Nelson unit through my local dealer. Put it on in about 20 minutes last night. It was very easy to do. Works just fine, I don't see any RPM loss.

Hmm... Someone should have remembered but if you switch the left and right valve covers it make putting oil in the engine a lot easier. But it's lookin' good.

Richard,

actually, they should have mounted the filter 180 and it would have been fine.

they are made to face either direction.

Yeah Richard, good point, I think I'll do that. Maybe I'd better get in touch with Kohler and see if that will blow my warranty!

scott,

just remove hose, unbolt elbow from the carb and remount opposite direction, unbolt filter housing and rotate elbow 180 and re-mount filter......simple....5 minutes.
