Customer Question

I have a JD 4310 with hydro statc transmission. The engin starts and runs just fine. let it run for 45 minutes under on load no problems.
The tractor will drive forward or backward and the front end loader and box scraper hydraulic also work fine. After I drive it for about 500 ft the 30 amp Ignition fuse will blow.
I have looked for any worn wires but could not locate any. Any suggestions on what the problem cousl be ?
Thank You
Dave

When fuse blows, does tractor die? Or what quits? The only difference from no load, to driving the tractor would be the foot pedal and the switch that it works. Look for shorted or bare wires at the hydrostat pedal switch and harness.

the tractor dies. i hadalso had it blow the ignition fuse and die after i have stopped and was trying to dump the bucket .
Expert:  Curtis B. replied 11 months ago.

It does not seem to be a component, but a bare wire or short seems to fit, and the place to start would be the hydrostat pedal area. Common place for bare wire is where the harness gets clamped down on frame through a clip.

how do i remove the foot pedal cover . there are only some plastin pusn on caps but no screws?
Expert:  Curtis B. replied 11 months ago.

Is there a floor mat over the cover you want to remove?

Customer: replied 11 months ago.
not the floor mat there is a plastic box that surrounds the foot pedal wireing under the floor board. there are black plastic "push in " fastners. Didn't know if you had any tips on how to remove them with out breaking them off?
Expert:  Curtis B. replied 11 months ago.

Take putty knife or flat blade, and slip under and pry up, the take side cutter pliers or needle nose and pull them out. If they break, you can find replacements at any auto supply.
