    Belt tension

    I searched (no, really - I did) but after ten pages I got bored without finding the answer: what is the proper tension for the 54MMM blade drive belt? Is there a measurement or a deflection (on a lot of cars they will tell you to depress the longest run of the belt a certain amount)?

    isn't it spring loaded? if ur spring is old-get a new one-good luck.

    Pardon my ignorance

    It is spring loaded, but I thought that might be adjustable. It only has 100 hours on it so I'm sure there's nothing wrong with it.

    it is adjustable-only in how good the spring is-ok.

    my old wheel horse had a slide that was hooked by a spring-but that slide would get in bad shape over time-so u would have to either replace the parts in it-along with a new spring back then-if them parts didn't work correctly-then yeah-ur blades didn't spin fast enough to cut the grass.

    as long as ur ends of the spring is hooked-thats it. done.

    Yet another day that I learn something. So the rule is: spring loaded belt tensioning is always going to work, and I never have to think about it. Just like non serviceable grease fittings on cars and light bulbs that never burn out.
