1975 JD 100 lawn tractor mower belt

Tue Dec 20, 2011 6:11 pm

I have aquired a little Deere mower and it needs a new deck belt. I can't find a manual online or any info on what size belt I need.

Any help out there is appreciated.

Is it an L-100 or a 100. I was able to find the belt for an L-100 which I hope is the one you have. On the Manual Server you will find the John Deere On-Line Parts Lookup and under the Sectoral Index for the L-100 8 - MOWER DRIVE BELT, SHEAVES, SPINDLES AND BLADES - it shows the belt as item # 6 GX20072 FLAT BELT 1 (B) (C) (SUB FOR GY20570)

I hope that helps

nope rudi, it is a 100. tiny little rider I took on trade. Made between 75 and 78. If I had 2 I could use em for roller skates.

I will try the JD dealer tomorrow, but they are next to useless here.

The mower deck serial # is h034g 382004m

I tried every permutation that I could think of to find a JD 100 Lawn Tractor. Same with the 34 in Mower Deck. Maybe they don't have the older Lawn Tractors in the online parts catalog. Either way I couldn't find anything. Sorry.. :big give up: I did try.

Maybe someone more adept on the JD site will be able to help......

In the John Deere Parts Look up Rudi posted, above. Type in 100 where it askes for model. Then scroll down to item # 1472. It lists the belts by John Deere part number - not size and length.

If the old belts are not present - it's to the John Deere dealership.

I went to the Deere parts site and searched for 34. Got back a listing for "1008 - 34 Rotary Mower - 15Apr03". Expanded out, it showed "7 - DECK DRIVE ASSEMBLY". That showed a deck belt of M41642 which you should be able to cross reference several places.

I presume that is the correct mower, but you probably want to look at the diagrams yourself to see if it looks right. It is a 2 spindle deck with 17-1/4" blades.

Ok, so how did you guys get the results. I oriiginally tried 100 and got nada, squat, zilch, nuddink :shock: That is why I asked it if was a 100 or an L-100. Same thing with the mower... figured out it was a 34 inch by the model .... typed in Mower Deck, 34 inch Mower Deck, 34 inch, 34, Mower .. always came back with nada, squat, zilch, nuddink ... ad nauseaum... :(


edit: Ok, figured out the D100 .... :roll:

JD Part # GX20072
