I was using my B7510B with 41 hours on it Sunday to move some materials and then shut it off while I did some handwork. I got back on to restart it and the engine wouldn't turn over, not even a click. The battery is fully charged and the glow plugs and other idiot lights work. I've also checked 2 of the safety switches that I'm aware of, the one that engages with the clutch depressed and the one under the seat. I rocked the forward reserve pedals, put it in neutral and disengaged the PTO. It simply seems like one of the safety mechanisms thinks the engine should not be started. Anyway, before I call the dealer with what might be a simple oversight, I was just wondering if anyone else had experienced a similar problem. Thanks in advance!
most certainly sound like a saftey switch problem, but just for the heck of it check the terminails on the battery, that they are good and clean and tight also check the ground where it attaches to the tractor! what were you using the tractor for just before it would not start?
I have had that happen to my B-7500, mine was a sticking HST pedal I pull up on the forward pedal hard and grease the zerk under the HST pedal real good.
Hope you find the problem soon, its probably something simple but aggravaing /forums/images/graemlins/mad.gifnone the less.
You need to check to make sure all the saftey connections are securely connected.
Also check the starter fuse...if the B7510 has it, I know the B7500 did.
I always like to make sure the engine turns over by hand (and check the oil) and then I use a remote start switch to turn the engine over with the starter to preclude any engine issues. Once I know the engine is fine I start the electrical troubleshooting...safety switches and fuses. If you don't have a remote starter you can short the starter terminal on the starter solenoid to B+ with a metal tool (be careful...do this only if you know what you're doing).
Thanks for all the suggestions. As expected, it was one of those safety switches. I jiggled around the PTO shift lever and sure enough it turned over and started. I thought it was something simple, but after working on laying a 75 foot paver sidewalk in 82 degree weather all day I guess I wasn't real focused when I was debugging the problem.
If you check the usual safety switches...... and this doesn't fix the problem.... check your fuses. There is likely a 5 or 10 amp fuse for your ignition switch.
Similar thing happened to me a few months ago on my B7510HST. I put a shovel that I needed in the field between the seat back and the ROPS. That jammed the seat so even my 200 lb couldn't make the seat ignition interlock switch engage. Thought my Bota was really sick until I remembered that pesky seat interlock.
