I'm hoping you guys can give me some suggestions. I have an L2500 which started having a stalling problem out of the blue the other day. Here's what's happening. I was backing down my driveway (which is sloped downhill) and went about 400-500 feet when the tractor sputtered and stalled. At the time it was in the high gear range (I was in high gear reverse) It restarted right away but when I hit the throttle it sputtered and stalled. I managed to get it turned around after starting and stalling a few times and when I had the tractor faced the other way (the nose of the tractor facing downhill), it didn't stall out. So, I put it in low gear range and backed up the driveway. It backed up for several hundred feet with no problems until I put it back in high gear. Then, it ran fine for a few seconds, lost power and sputtered and stalled. I have to drive it some more to be sure, but the tractor seems to run fine in low gear but stalls out in high gear. When I give it throttle it loses power, sputters and stalls. It also seems to sputter when the nose of the tractor faces uphill and not downhill. Other than this stalling issue, the tractor runs fine. Even when it sputters and dies, it starts up right away again with no problem at all. I suspect I'm having some sort of a fuel issue, but before I start fiddling with anything, what are the things which I should check or do, in the order of likely suspects? And just for clarification, I was not using the pto, backhoe or the loader. I was just driving the tractor itself from Point A to Point B when these problems happened. Thanks for the suggestions. (One more thing, there is no seat safety switch, so it's not that).

Check your fuel filters. I think you may have a clogged line or filter. When you are in high gears you pull more power which will require more fuel. I hope this works out the problem for you.

You didn't say what state you are in, so it is hard to figure if it's cold there. Do the filter stuff as suggested, particularly if it's cold where you are. Lots of people are reporting hydraulic/fuel system/ HST problems due to the cold.
It's hard to tell if the gear range relationship to the problem is a coincidence, are a causal relationship. If so, it could be electrical in some way. But the previous poster is quite right about more power needed in higher range, therefore slightly more fuel required.
If I find something on you model that could be helpful, I will post again.
Good-luck with it!

When it sputters is there black smoke coming from the exhaust? This could be a lak of air = Air filter problem. If it just sputters and dies then it would be a fuel problem. Could be a clogged/Jelled filter or water in the fuel, or even air getting in the fuel system some where. Also, look in the fuel tank to see if there is something that could be sucked down and block the fuel line feed!
I'm located in NJ. I think the diesel might have been somewhat jelled. It was in the 40's yesterday so I started the tractor and took it for a spin. It seemed to run fine with no coughing or sputtering issues. The only thing I noticed was that it's not 100% as quick as it should be in the higher gears (gears 6 & 7). I didn't try gear 8. The air filter is clean. I also put in some diesel 911 as a precaution. But today another problem came up. I drove the tractor up to the house and turned it off because I needed to add some UDT. I add some, hop back on 2 minutes later, turn the key and nothing. The gauges move, the lights work, but no sound, the engine doesn't even try to turn over. Totally dead. So now I'm thinking maybe there's an electrical gremlin somewhere causing some problems. I made sure the pto lever was off so the plunger was depressed and even pushed the neutral safety switch back with my hand while trying to start the tractor to make sure that was fully depressed. Those are the only two safety switches on this tractor that would prevent it from even turning over. So there's something else going on here I have to figure out. It's always something, isn't it? I appreciate all your guys input.
Just to conclude this thread, here's what I did. I bought a bottle of diesel 911 (the red bottle) and poured a few ounces in the tank and let it sit overnight. The next day it ran fine, no coughing or sputtering at all. The electrical 'no-start' problem turned out to be a bad neutral safety switch. I don't endorse this method, but I diconnected the switch, jumped the wires and the tractor fired right up. I'm going to replace the switch, but for now at least the big guy is running, and apparently just in time to move some snow..........
Thanks again for the suggestions!
