I am having trouble finding blades for my mowers. Can somebody help me out. I have an 07 Exmark Triton 60" Z. I use the Exmark wavey Mulching blades. The number stamped on the blades is 109-5396. The blade is 20.5" long and has 15/16 center hole. The second mower is an 06 Exmark Phazer 34". I also use the wavey mulching blades on this mower. The number stamped on this blade is 109-3129. The blade is 17 1/4 inches long and has a 5/8 inch center hole. I have tried Texas Mower Parts and Mowparts and didn't see what I needed. I appreciate your help.
