Gravely zt hd 52 deck belt

[Yard Troll]

Fourth time using the 2021 model and the drive belt was severed. Replaced the belt but now the deck belt vibrates against hydro gear housing. Tension springs were put back on the way they came off. Does the tension need to be adjusted on the deck spring even though nothing was replaced on the deck?

I failed to include in the initial post that the deck was not engaged when I noticed the deck belt vibrating so much. After more investigation and doing just what I did when I noticed it, it seems to happen when the throttle is roughly 1/4 full. I was backing it out of the garage just after replacing the drive belt and only advanced the throttle about 1/4 to test my drive belt replacement. Any other throttle setting and the deck belt settles down. Neighbor has the same mower except 5 yrs older. Going to see if his does the same thing.

I would be more concerned about why you severed a drive belt. Any idea how/why that happened?

As much as I try to keep an eye on the debris, I think a branch got up in there. I've been slowly trying to reclaim some of the yard my father-in-law let go over the years.

I use a Lowes 5 gallon bucket & a pickup tool made by Unger 36" long to pick up pine cones, twigs & sticks, etc. before mowing. saves on blades, belts, pulleys,etc.
