While mowing today I seem to have lost the center bearing from the center pulley of my 36" rear discharge mower. Looked everywhere and could not find the part. Checked all local places in my city for something to solve my problem to no avail. The pulley is a 31/2 inch pulley. I've taken the numbers from the deck and hope someone might be able to help me in getting this fixed or a replacement part. My mower identification number is 0536mr01 - 5411 and the number under that is 9253. My tractor is a C-111. Grass is growing as we speak. Can anyone offer a suggestion?
