JOHN DEERE F510 F525 RESIDENTIAL FRONT MOWER Service Repair Manual

The John Deere F525, a front cutting machine, has 3 fuses.
20 Amp
15 Amp
10 Amp

Check the 15 amp fuse. I believe this supports the PTO clutch. If you replace the fuse and it blows again, check the electric clutch. You will likely find burnt or melted wires. The bearings do go out on these clutches causing them to run hot and eventually burn up.

PTO Clutch will not engage: There is a very fine one page discussion on evaluating electric clutches at this site:

http://www.messicks.com/Articles/FixingElectricClutch.aspx

My JD tech manual, which covers the entire LA 100 series, agrees with the electrical specifications. It states that the Electric PTO Clutch should show the following:

Resistance 3.7 ohms
Current Draw 3.25 amps
It does not give the air gap.

It does include a note to check the PTO Clutch Key for damage or if missing. So there is a drive key between the PTO Clutch and the shaft. Additionally, it recommends checking the tightness of the cap screw. That's the screw or bolt that holds the clutch on the shaft.
Cap Screw torque 55 lb-ft (75 N.m).

If the fuse blows, I recommend you check the resistance of the clutch. If the clutch is shorting to ground it will show zero resistance when you ohms the connector wire to a ground position. In which case, you will have to replace the clutch.

Other possibilities.
On the F525 there is a cut-off switch in the hydraulic system. It is a low pressure cut off. If you were running the mower and deck and then it suddenly stopped, it may be low pressure in the hydraulics. It will not automatically reset as you are using the same volume for the drive pumps. Once the oil gets low enough it cuts out the deck drive 1st, then the drive pumps.

Ok what is the problem? fuel pump not working? try checking for dc volts at pump.

Remove recoil/rope cover and engine cover if installed.

Hi,

Hi and welcome to FixYa, I am Kelly

By secondary belt I am assuming you need the deck belt routing. Here is a picture of the front deck belt routing: http://opebycrigby.tripod.com/decks/jd/jdf525.jpg

Thanks for choosing FixYa,

The front mount mower has a safety switch on the park brake linkage and the seat belt linkage as well as on under the seat which is for the PTO,The one under the seat on the linkage just behind the battery is a culprit that needs adjusting to get the PTO to engage but it sounds like you need to deal with the seat switch circuit or replace the seat switch.
