I purchased a new 2000 Toro Z-Master which is a 2000 mower but after knowing how to read the serial# mine is 2830107911 which is a 98 engine.I was kinda upset that my dealer told me the engine was a 2000. Just start from 70 and add the 28 you get the 98yr, So he a i have been talking about making this prob right. He called me on my voice-mail and i just got in around 9pm,he looked up all the notices on that engine and told me that is has already been upgraded so thats nice to know. Guess thats the reason i haven't had any problems with it at all, it even starts without chokeing and doesn't backfire,he did say my gas tank caps needed to be updated someing to do with the venting. So all you guys who have Kohler engines check your serial# and see what yr you have. 30 is 2000 and so on. Marks Mowing Service

Yes the engine was built in 98, it was late 98 though. Towards the end of October. The next three digits after the 28 is the day of the year it was made. 001 would be January 1st. and 365 would be December 31st. The dealer is correct that the build does have the improvements done already.

I have a Gravely 260Z with a Kohler, Serial 28320########. So it was built on day 320 of 1998?

Question: Which motors were the bad ones? Before what date?

I have a little over 1200 hrs. Have had no problems other than occassional chatter at start up. Switched to Mobil1 Synthetic 15W-50 and chatter went away.

Mine was built in 6/99,it's been one problem after another,for the most part..As far as Im concerned,there are no good 25Hp kohlers.If there is a date which they are good after-it must be the ones built in 2000,ours are junk
