Hello all!
I have a new low hour Zero turn Z248F.
Its has excessive belt slap. Always has from the day I purchased it. I tightened the spring for the tension pulley and helped a little. Problem is its already broken a belt. The new replacement OEM belt installed is also starting to come apart and has been used only a few times. I have again ordered another belt. At this point I'm pretty frustrated. I purchased the Husq over a Cub Cadet due to the heavy duty deck and it also went thru a lot of deck belts.
To me when the blades are engaged the belt should run smooth and the only noise is the blades spinning. This thing sounds like a junk truck.

Has anyone else experienced this issue? If so how did you rectify the problem.
I'm pulling the deck off tomorrow and inspecting all of it.

I have seen his on quite a few Huskies
If you have an electirc PTO then you can slip another idler in.
All of the ones I have seen slapping had too long a run from the outer pulleys and not enough arc of contact.

It has the electric PTO (clutch system)
I'm not sure how or where I would add an additional pulley. If this is whats causing the problem, it seems that its a simple fix the manufacturer should address. Simple engineering and the pulleys are cheap.
I removed the deck. Polished all the pulleys so there are no burs to cut the belt. Greased all the spindles. The spindle bearings were all smooth.
The two larger pulleys were smooth. The small idler pulley was rough and had excessive play. The idler lever was slightly elongated. I have ordered both a new idler pulley and lever. I find it hard to believe that with only a 100 hrs on this machine these are already in bad shape.

Also, In the parts break down of the deck, it shows a washer under the idler lever for it to rotate. Mine was not assembled with one. It is attached directly to the deck with a bolt that goes thru the pulley. It has wore all the paint off the deck to bare metal.

See attached link.

You can see Pulley #10 and Lever # 17 at attach location it shows that washer . The pulley has a washer built in to that rides ABOVE the lever. Nothing below it.
Anyone that has this model, let me know if yours has a washer below the lever.
Thanks

I have seen these washer completely worn away here allowing the arm to start flopping around causing belts to come off.

Going to be hard to prove, but good chance it was supplied without one fitted.
Just done a Timecutter where the similar plastic washer was not there.
It also snapped the belt . but when inspected the tension arm pivot hole was flogged out twice its normal size
