If you get no response from here consider buying the JD technical manual.
People scream blue murder about the price but they are excellent, comprehensive and even have diagrams in the electrical section that shows exactly where every part is, where the connector for that part is and how to test it, At the start of every section there is a "theory of operation" that clearly explains how the whole lot works so you know what to do & why you are doing it,
The book will pay for itself the very first time you don't take your mower to the shop and when you sell ( even if it is totally wrecked ) you will get a price substantially above the general level and 2 to 3 times the price you paid for the manual.
I sell a few used ones down here and will get $ 500 ( Aust) more if I include a $ 100 manual + a printout of the free owners book.
Found that out by accident so everything that I sell through Evilbay / gumtreee/ craigslist etc has a print out of the technical manual.
I think that it my have bent your Reverse Pedal just enough to not make contact any more with the switch. Follow the pedal under the mower till you find the switch. It is under there but exactly where will be a hunt and find type of ordeal.
Hi Again...
Any idea as to how I can clean-out the area where the Fuel Indicator Pivot is located ? The JD CSR tells me that it's between the frame and the Fuel Tank. I'm guessing that the entire frame has to be lifted for access. The Fuel Indicator is Intermittent. Even when the tank is completely empty, the indicator can remain stuck at the top, indicating a full tank. Not very reliable.
Thanks !

Fuel sending units are inside of the gas tank not on the outside of it. How could it tell how much fuel if it was not in the gas?
When I first started looking into this all I could find was automotive style fuel pumps for your mower. Sending unit is attached to them and they sit in the tank. After looking again this morning I am not sure my search worked at all yesterday. I am inclined to believe Bert on this. His above post sounds logical. I normally do not speak of others post but I think he is correct.
Picture attached. I hope this helps.

Hello & Thanks Again to All...
I'm still in the dark as to how to get to the Fuel Indicator Pivot so that I can clean it out and let it swing properly and give me a good Fuel Reading.
Thanks !

I told you in post # 9
Pull off both rear wheels
The fuel indicator is right there in front of your eyes,
Well in front of my eyes because I put the rear axel on 20" high stands so I can sit on a seat.
Looks like the link to the parts page did not work, however if you type d140 ( note no spaces) in the little window at the top it will bring up your mower as a clickable link.
Click on the line that looks like this 10445 - D140 100 Series Tractor - 02Nov16 ( FR DE IT ES )
Then click on this Sectional Index
Then click on this 30 - Fuel And Air
Then click on this 20 - Fuel Tank (100001 - )
Note there are 4 fuel tank diagrams ( 17-18-19-20)
17 is the first type without the idiot fuel level indicator
18-19-20 are the new type
18 & 20 are the same
19, the image Blaz posted is the same tank, but a different image including the California only charcoal filter and showing the fuel indicator as disconnected parts.
IF you bought the digital version of the technical manual which you would have by now , then you could have read the :-
THEORY OF OPERATION
The rear of the fuel tank ( Part 1 ) sits in a channel in the frame which allows it to pivot up and down at the front end.
The front end of the fuel tank sits on the foot of the indicator arm ( part 11 )
The indicator arm itself pivots on the support base ( part 12 )
The front of the fuel tank is held up by a pair of springs ( part 13 ) which span from an anchor point on the fender ( not shown in this diagram ) to bushes ( part 7) over protrusions moulded into the tank and fastened by a spring clip ( part 6).
AS fuel is placed into the tank , the weight of the fuel tank increases causing it to stretch the springs allowing it to depress the arm which being a bell crank causing the visible indicator to rise.
If you use the link to the JD parts diagrams and ferret a bit you might also find section 85 - Mower Deck And Lift Linkage
Clicking on that will reveal subsection 44 - Mower Deck Lift Linkage
PAY ATTENTION THIS IS IMPORTANT
This diagram is wrong it is for the previous model ( first fuel tank diagram 17 ) without the fuel indicator.
The deck lift rod ( part 21 ) is incorrectly named "universal driveshaft".
On the older system it is retained by a pair of steel saddle clamps ( part 15 )
On your mower the deck lift rod is retained by the support base ( part 12 in the previous diagram ) which is plastic.
if the deck is given a hard whack when on a high cut position the lift rod ( part 21 ) hits the plastic support base and it breaks as mentioned way back in a previous post
Grass accumulates between the indicator arm & the support.
It also accumulates under the fuel tank with the same effect.
Don't forget to grease the axle or the wheels will rust solid to the axle.
Hello All...
While cutting some 8.0' high White Weed, a small tree fell over and stuck on top of the Reverse Pedal. I backed-out of the jungle, then drove back to the house. No Problems.
When I tried to restart the engine, it wouldn't even crank. I called JD Customer Service who relayed me to a local dealer. They told me it was possibly the Reverse Switch beneath the frame; but couldn't point me any closer. Does anyone have a photo of where this switch is ?
I'd also like to know how to access the Fuel Level Indicator so I can clean any grass and debris from it. JD Customer Service tells me that this may be the problem for Intermittent Reading of my Fuel Level. Help me if you can.
Thank You !
