Aloha,
my name is kevin , im from the island of Kauai , Hi. and i just bought a used John Deere Hydro 185. this is my first riding lawnmower and not sure what i really got myself into. It looks really cool and im super stoked that i really have one. when i purchased this lawnmower it was sitting one the side of the road with a for sale sign on it , it has been repainted and gots some rust ,but not sure what year and dont know what the serial number is because the serial number plate has been removed. The original owner said everything worked fine , and it testdrove fine too. but when i brought it home to do my lawn lololol the darn belt (the one on the mower deck) busted on me, within the first five minutes. So now im online trying to buy parts for this this thing and i dont know the year , serial number or deck size of my mower.
could anyone here help me out?

Mahalo,
kevin

Welcome to GTT!

:wgtt:

Kevin, You can always take the busted belt to a store that sells belts. They can match it up pretty easily unless pieces of the belt are missing. Sometimes the belt has a legible part number on it too. As far as the deck is concerned, you can measure the width of the blades. This is a thread that also may help you identify your tractor. We have a bunch of knowledgeable members who can help you even further if you can provide some additional information and/ or pictures. For example, the engine information can help.:drinks:

Hello Kevin and welcome to GTT!!

Are you sure the serial tag is gone? It should be right above the left tire on the frame rail. Maybe it was just painted over.
That 185 was made between 1986 and 1990. It had two deck sizes, 38" and 46". Factory engine was a Kohler single cylinder 17 hp.
You can narrow it down by the link that dieselshadow posted.

Please do not buy aftermarket belts - you will regret it. JD specs it's belts to very specific belts. Their belts are size differently as JD uses a different groove angle that most other belts use, and they are made of specific materials. For online parts go the Keeping it Green, which has a list of replacement parts for every JD lawn and garden tractor. They are a John Deere dealer in Missouri. http://www.keepingitgreen.com/

The 185 was Deere's top of the line lawn tractor in the late 80s, from 1986 to 1990.

Much thanks!

I would like to thank you all for your help! I wasn't expecting such quick responses !
@ Scotty370 , so if my mower deck has three blades(wich it does) than I have a 46" deck?
Since my secondary belt is bad , I should probably get a primary belt too, it will save in shipping. Thanks alot guys ! I really appreciate all your help, I'm sure I'll have more questions and now I know were to go.

ALOHA,

Kevin- Realize that this is an "Open Forum" and we're not Doctors! I just enjoy searching for that 'phatom' answer that I need! I found yours, through Google images, Tractor Data, and JDParts.com. There are no guarantees that the belts I suggested are a "foolproof" match, but it gives you a place to start, and make your own decision before you purchase something. If you have the old belt, a trip to JD will allow you to somewhat match it up! Yes, I'd replace both..........Let us know how you make out!:unknown: ~Scotty

OH! And welcome to Greentractortalk! ~S

Kevin- Just another thought.........

If that deck belt broke, or burned up so quickly, You might want to check the three spindle bearings on the deck, and make sure that they're spinning freely. They're not hard to replace, but are critical to belt life. Give the group your feedback. ~Scotty

Sorry- Should have mentioned that earlier........~S
