Hey I just bought a 1026R used, about 400 hours. He supposedly had taken it to the dealer at the different hour things to do, I even saw the receipt for the 400 hour maintenance service at the dealer.
I first noticed an issue the first time I mowed, about 5 min into mowing I started dropping RPM and so I turned mower off. Whenever I would turn it on it would start losing RPM right away, even with it just sitting there. I noticed I was probably at an 1/8th tank or less so I filled it up and when I first started trying to use it again, it was blowing out a lot of smoke and stuff, but then it's like it became "cleared out" and everything was normal again. I thought maybe it was just something with running low on fuel or something. I've mowed with it and done other stuff for at least another hour or two. Then right in middle of mowing today, I came to a stop (on a slight incline if that matters) and turned mower off. I think I then pulled the throttle back all the way to idle it while sitting there, and it started dropping rpm again and shaking pretty hard. I tried to move throttle forward and it sort of increased RPM but it started dropping right away, and shaking, and then died (this was just sitting there, mower off). I then got it running again and got up to the house where it's flat and tried starting it again. As soon as I start it and up the throttle it starts losing RPM and even blowing some smoke etc. I've checked the oil and it seems fine, it was just at dealer around 15 hours ago with previous owner supposedly and had the 400 hr maintenance done. I'm far from a diesel mechanic, this may be something stupid easy...
I uploaded a video of me starting it and then I give it some throttle, and you can see what happens.
Any help is very very appreciated!!!
