I have a RZ4824 ZTR mower. The transmission levers have lost some responsiveness, both forward and in reverse. In inspecting the unit, I found that the transmission drive belt seems to have excessive deflection in it - a little more than an inch of deflection. My rule of thumb for v-belts is 1/2 inch of deflection. Does the idler pulley need to be adjusted to reduce the amount of deflection? And can you offer advice on tightening the belt? Behind the seat and in front of the engine, I see a half moon slot with a bolt that has a heavy spring attached to the frame and looks like what I need to access to adjust belt tension. I've attached a photo of what I think that I need to adjust. Am I assuming correctly? If so, do I remove the big spring, loosen the lower nut and slide the pulley to get more tension, tighten the bolt and reattach the big spring? Thank you very much for any guidance on this.
