I can say that is a nice mower because i have the same exact one :biggrin: Here lately though i have been trying to quiet down some rattling going on around the deck area when the blades are on and the engine is at full speed. At first i thought it was the anti scalp wheels on the deck so i tightened them all down except the one underneath the deck but that didnt fix it. Everything seems tight so i havent a clue where the noise is coming from but its loud enough to hear when im mowing. I got just over 10 hours on mine so far.

I have a similar noise. I believe it's the belt tensioner. It sounds like the tensioner spring is hitting the deck. I prolly put some sea deck I have around the house to place in between the deck and spring. See if it helps.

Looks nice and clean! Did you get the Kawasaki engine or the Brigs? I think i found that spring you spoke of, i noticed it has left a spot underneath it on the deck where its been rubbing so i put something there to see if that will quiet the noise down.

I figured out my little rattle noise was the belt tensioner spring hitting the deck.
I put a piece if seadeck (boat deck foam) on the deck and stopped the noise. Hope this helps others!


Used the mower for the 2nd time. Cut my front yard in 30-40 min, 2.6hrs on the mower. I'm really impressed with the mower. I can not imagine what a full commercial mower is capable of, I'm thoroughly pleased with my new mower. I may actually mow my yard once a week now and not dread mowing.

Yes, thats the same black spring that I put something under it, next time I mow soon I will see if it has helped or not. Theres no doubt, its a good machine, built to last. To be honest though, I am still learning the zero turn thing, trying to not tear up the grass when I turn and during zero turns. One thing that makes it harder for me to gauge when to move the leavers back into reverse is there isnt much feel for a neutral point if you know what i mean. I guess I just need to get used to stopping almost completely and then do the turn or something. Ive watched a few youtube videos on the subject as well. I noticed the tires on the mower seem very sticky as well, much better than the old sears I had before.

It took me two seasons to learn how to make a zero turn without causing divets. One of the easiest ways is to make what is called the Y turn. Just remember to keep both back tires moving. When the inside tire stops moving during a turn that is what causes the divet. If you stop at the end and start backing up a little before pulling one lever backwards further. Both wheels will be moving then and you can spin around without damaging the turf.

I have the same rattle on my zthd 52, do you think it means the spring needs more tension?
