Hello,
My New Holland 1725 has recently been losing power, as if there is a fuel issue. It always starts fine and runs perfectly well for at least 20 minutes, then the rpms will drop for a second or two, at first at wide intervals (20 minutes or so). Within an hour, these drops start happening more frequently and last longer--5-20 seconds. Sometimes they become so frequent and the power drops so low that I have to shut off the tractor and walk away. An hour or two later, it will restart as if nothing happened. I've been brush hogging a thin, weedy field with it; it seems to happen more uphill (but not always) and is partially cured by taking the load of the engine, by resting out of gear or with the PTO disengaged several seconds (but not always!).
What I have done: Air and fuel filters replaced at start of season (problem started last fall). Ran a pint of Sea Foam through with a tank of gas--1/2 way through the second tank with this treatment in it now. I also blew clean the tank cap, thinking it might be clogged--this had no effect, but loosening the cap seemed to somewhat ease, but not fully solve, the problem (not convinced that was not a coincidence, but I will get a new cap).
What problem can this be that always goes away by the time I restart the tractor, that seems somewhat but not always connected to power demand? It has happened driving along on level ground without an attachment running. Thanks in advance for any advice!
