2007 3510i low power

[Jeffery B]

My 3510i has become weak. Will only reach 2200 RPM at maximum throttle. Any ideas

Can you give more details? How many hours? Which engine, Yanmar or Kukje? Service history?

The more information you can share the better.

Is it smoking excessively?

When was the last time you changed the fuel filter?

Is your fuel good and clean?

Check the air filter too.

Not smoking hardly at all

About 10 hours ago

Pretty sure, just filled up last week straight from the pump at store

Did all this start right after changing the fuel filter?

How long has this been doing it?

I agree with K5, the more information you can give us, the better our help could be.

Well, i can't answer that. You see yesterday was the first time i have sat in the seat in 2 years due to illness. My son 48 and grandson 25 has used and maintained the tractor in my adsence. Now both are well versed in operating heavy equipment since it is their jobs. Using the tractor yesterday to move a pile of dirt i just had delivered it just did not perform the way i remembered. Today i talked with my son about it and he agreed with me. He had not noticed it since all he used it for was to use it occasionally to upload some lumber or to boxblade his driveway. I'll call my mechanic tomorrow and have him come out tomorrow and I'll let y'all know. Thank y'all for your replies!!!
