Tractor
International 404
I am no mechanic, so I am looking for advice on what the problem might be. I noticed a few months ago that the tractor started missing while it was idling. This weekend, I was grading a driveway with a pretty heavy grader, and the sound of the engine got very deep, and there was a huge drop in power. I was able to finish the job, but I just bought a heavy duty shredder that I probably won't be able to use until I fix this problem. The sound of the engine is still deeper than before and with far less power. Also when I turn the ignition off, I can hear air coming out of the pistons? kind of like it's exhaling. On a side note, the hydraulic system screams pretty badly. I need to change the fluid, but I didn't know if this would have contributed to the problem. Any thoughts?

Perhaps the screaming hydraulic system is running up against relief valve taking power from engine?

Could be. I'll try changing the hydraulic fluid first and see what happens. Thank you for the tip.
