If you have a 1025R with a 60" auto-connect deck, is your deck kind noisey at idle and then smooth out as the rpms go up? Kind of a rattly sound. At idle (1500) if I start the deck it has a lot of rattle sound to it. I had my wife get on it and start the deck and the belt is flopping around and the tensioner spring is jumping back and forth a lot. If I raise the rpms to 3000 or so, it is not noticable. I took the deck completely back off and removed the belt. All of the bearings feels smooth as glass. I actually wonder, is there a chance that the blades are causing it? When I look under it, the blades look super cheezy and are thin and even kinda wavey looking like a cheap stamping. I wondered if they could be causing a uneven airflow that would make the belt not pull evenly and cause the low speed noise. Another cheezy piece I noticed is the little short driveshaft that goes from the auto-connect to the rear pto. I can turn it by hand and the female portion of it (rear part) goes at least 1/8" out of round as you watch it turn. It's like they didn't get the hole for the front shaft machined in the center of the rear part. Let me know if your deck makes any noise other than the blades whining. Thanks!
