Losing power when warm. Air filter and fuel filtes changed. What next?

[justin1749massey]

Hi, for a few weeks now when I take my tractor I lose power especially on an upgrade. I changed air filter now the fuel filters and I tried mowing. After 20 minutes I had to drop a gear. Won't pull itself ahead. If i kept on I'd have to jeep dropping gears and up the pto . Barely crawling. Then hardly make it back home. Any ideas. What about the hydraulic oil filter. If dirty would it cause this?

Well, it begs the simple question, "Did you take the brake off?". If your hydraulic filter is blocked, your loader and the rest should be running poorly as well. If you haven't cleaned the metal filter in a while, you should. Can you take a peek at your sight glass to see if your fluid is discolored? Any fluid related problems seem to get worse in the winter, so giving it a once-over might be in order regardless. As usual, try running it with the cap loose to see if any vents are blocked. I don't think you have a vented cap, but if there is a vacuum in the system it's worth figuring out why.

Ya, the brake is off, loader and all seems normal. The oil in glass looks normal. But hydraulic oil and filter are due for changing.

When my NH had the same symptoms, after similar remedies, I found there was gasoline mixed in the diesel fuel, which boiled after the tractor warmed up. A simple check is to drain some fuel into a shallow pan and you can smell the gas fumes evaporating out of the diesel. I bought that watered down fuel from a large truck stop and I believe it was done to sell cheap gas at diesel prices.

Really, I got a conditioner to pit in the fuel will that help?

blockage in suction intake filter could cause that.

edit-disregard I misread initial post.would not apply to this unit.

If you have tried everything else, drain the fuel and put new in.

Ok thanks. I'll find out today.

I had a tractor with a similar problem and it was the fuel transfer pump that was failing. Might be something to look at?
