    If you have an electric clutch and are running doubles, wheres the best spot to set the throttle? Also, how tight should your belts be? seems like if i losten the idler springs a little, it is a LOT eaiser on the clutch and engine. Anybody else got some ideas?

    I've always been told about half throttle then slow or stop and then engage blades.Easier on clutch engine etc.I would check with dealer or manual for your spec. mower.

    Set the throttle as low as it will handle starting the blades - That is only common sense. I see people all the time rev the engine to full bore then start the blades - Why?

    Engage at the lowest possible RPM you can without stalling.

    On some engines, esp. Kawasaki air cooled, you can put the choke on at slowest idle, then PTO on, then choke off.

    On my Kawasaki 25 this lets me engage at absolute low idle without a stall.

    My 26 EFI Kohler let's me do the same thing.

    A frind of mine bought a new Exmark Lazer with 20 KAW. The dealer told him to always engage at full throttle. I have warned him against this, but he is going with the dealers advice. Smart of the dealers part......"Hey bring the mower in when you need a new clutch!"

    As Albemarle Lawn stated, if you have a seperate choke knob, apply 1/2 choke and 1/2 throttle and engage. The enrichened mixture that the choke gives you prevents possible stalling when cold.
