    Hey Smitty,there are no belts on a Walker deck.Each blade is conected to a gearbox witch is conected to a center gearbox. My blades overlap one and a half inches.The timing I am refering to is in the gearbox. I recently changed a box due to bearing failure. After putting it together, I found that the blades would not rotate. Had to take it back apart and (time) the gears so that there would be clearance betwene the blades. I think where the confution is, is on a Walker blade, there is a hub that is mounted on the blade that has a slot that holds onto the blade shaft. Not a circle like on most mowers. So the blade only goes on in one position.<p>----------<br>Yesteryear L/S<br>Hollywood Fla

    Bobby says:<br>&quot;Hey Smitty,there are no belts on a Walker deck.&quot;<p>Oh yes there are.... :) <p>My 52&quot; side discharge/mulch deck has a belt instead of gear boxes. And I believe that the 62&quot; is belt driven also. Now if you want to get technical, the belt is driven by a gearbox but the blades are on spindles and driven by a belt.<p>But you are right about the timing on decks with gearboxs. Has to be done. <p>Jim

    Sorry; I figured it was a given that Walker type GHS decks had gearboxes, I was referring to regular side dicharge types like the other 98% of mowers have.<br><p>----------<br>Smitty ô¿ô<br>

    About the mismatched blades.... To throw away blades is rather ridiculous because provided they're not damaged too bad and the tip is still there they can be saved. HOWEVER, I choose to run Dixie chopper blades on all my mowers including my Exmarks. They are a little thicker steel, and are a bit cheaper. They look the exact same,(bevel length, lift fin, etc.) but they ARE different. Because of the differences in thickness, I have to be careful not to run the two together on the same mower or it will leave marks. Just a little tidbit of info.
