H Folks, sorry it took me so long to reply (business trips). All the fluid levels are ok, but it does need an oil change and transmission fluid change. Air clearner is just a little dirty (I did blow it out just in case. The power loss is noticable anytime I try to make it go faster... The hydraulics fluid lines to the loader are coated black from the exhaust. The exhaust is excessive whenever I drive it, hard to tell if it is excessive at an idle. When I drive it it is not obvious that the exhaust is black, but the smell will give you a headache fast.
I did work it pretty hard with a rototiller and then I ran out of fuel (my bad). I replaced the fuel filter, but had some difficulty getting all the injector lines to bleed. I also replaced the air cleaner at the same time (it was really dirty after the rototilling). I finally got it started. It is a 3 cylinder engine and have been told by a neighbor that it might be 1 or all three injector or the injector pump.
I will check out the brakes. I can get on a slight hill and see if it rolls freely.
Could working the little tractor be the cause of the excess exhaust / power loss? Right now it isn't much use.
I really appreciate all your guidance. Thanks
