Loss of power

[SSGT]

Hi, new to the site with a new B2601, 44 hours. I'm 5 hours from a dealer so I am hoping someone might be able to diagnose my problem. This started yesterday, under power, like scaping with loader bucket, the tractor looses power and twice stalled. The scaping was very light, not enough to normally cause a stall, just loose brush. Today while pulling some roots, not a lot of stress, I experienced another loss of power and the tractor exhaust started smoking. Getting the tractor up the hill, back to the shop, she smoked substancially and felt as if she was running on one cylinder.

Iv'e checked the oil level and the air filter, both in order. Fuel is topped off. Any thoughts on my problem. I am not new to Kubota, ran an L3350 for 25 years. Thanks.

I would check the fuel fitler and flow at the filter, also check the vent hole in the fuel cap. I have a much older tractor so not up to date on these though

it sounds like mine acted when the air inlet sucked in enough snow dust from the air while snowblowing that the primary (large) air filter element was clogged with snow/ice and it starved the engine of air. Power started to decline and a bit of exhaust smoke started.
I doubt that's what your dealing with out on the west coast there. You mentioned the air intake and filter were clear.
But just in case you were dealing with snow, and parked the misbehaving machine in a warm space long enough to melt out any ice/or snow buildup in the air filter housing.

When my B2910 was very new, I had an issue where it would run well, then almost die, recover and do the same thing again and again.

Almost went back to the dealer, but on a whim I decided to change the fuel filter. That fixed it.

Problem was I bought off-road fuel at a place that apparently did not sell it often. Plugged my fuel filter to the point I could not blow air through it (using my mouth). Don't know how the tractor ran with that filter but it did, then didn't, then did...

So I am in the camp that says change your fuel filter, check the fuel cap to make sure the vent is open, and check the air filter.
