Why not chains, and not belts?

    I was just thinking about something, but why don't we use chains and gears for mowers, instead of belts?

    Belts are faster, easier, and cheaper to replace when they break. And IMO it in unnecessaery to have two sets of gears running in an oil bath to each hydro pump on a ztr. All that means is the mower would be more expensive to buy and more expensive to fix if one of those gears broke. Also if you got on a hill with the gears running in an oil bath the oil would run to one side and starve some of the gears for lubrication. Belts are way to go.

    I had a "White" brand chain drive mower. It sucked. I cannot stress that enough. Put new chains on it, kept it greased and still broke the chain 3-5 x's per week. I always had a bunch of spare links, connectors, and tools with me. Finally sold it and would never even think of owning another mower with a chain again.

    the cheap dixon ztr uses chain drive. they are a ton of mantenance.
    chains stretch WAY more than a belt ever will.

    also they are heavy, and when they stretch they wear the gear teeth. both need to be replaced as a set.

    I'm not sure if it would be possible to obtain the same blade speed with chains. Man, could you imagine the damage a chain breaking while you are mowing could do? It might tear up your mower, or leg, or whatever else gets in it's way.

    I was thinking about it because as I watch American Chopper sometimes they use belts and sometimes they use chains. I just was thinking, why couldn't mowers do the same thing.

    i thought you were talking about drive componets.

    some really heavy duity mowers have shaft drive.

    i thought the chaind on the choppers were for deck raising/lowering

    An important part of a belt drive is its ability to slip when you want it to, as in a turn. A direct chain drive would not allow one side slip and the other side to pull in a turn, at least given how the current 5-speed transmissions are configured.
