So, long story short, my father has owned an 855 since the late 80's that I grew up riding and using. I'm very comfortable with his machine and the various noises it makes. I bought a 755 this spring, I haven't used it much since but will start in the coming weeks. One thing I notice about it is that the engine is much more "tappy" sounding than my fathers 855. The tachometer is broken on the machine which I will be taking out this week, the hours read 400ish which I'm imagining it has more on it than that. I did a valve check using the JD manual, the tapping may have gotten slightly better but it is still very much there. The tapping quickens with rpm and for the most part isn't noticeable at idle. It currently has a 60" belly mower on it, with the mower engaged and at proper operating rpm it seems to bog down pretty substantially when I hit any kind of incline or take off quickly. Im used to running a 72" deck on the 855 which it handles no problem.
Does the 4hp really make that much of a difference? Do the 755 diesels sound that much different than the 855's or do I have some kind of issue going on here? I may be reading into the noise too much but wanted to see what others out there experienced with these tractors/engines. The tractor got new filters and fresh oils when I bought it. Any input would be greatly appreciated, thanks! :drink:
