    Anyone know anything about the Ferris IS 3100Z?

    Mine keeps throwing the belt drive from the main pulley to the blades on the deck.

    By my eye I cant see any pulleys that are bent or out of alignment, I have bought new belts and it doesnt help.

    I see no adjustments I havent tried.

    The owners manual might as well have been written by a 5 year old with ADD.

    I'm THINKING it might be the fact that the deck is maladjusted on the chains, make it's angle too steep... but again, by my eye i cant see anything that sticks out.

    Mine did that for the first 10 hrs. My dealer replaced the pulley at the back of the deck that directs the belt towards the motor to a larger one. Never slipped off again.

    What Mr. Johnson said.
    A friend had a Ferris painted Simplicity orange that kept throwing deck belts. After several trips to the local dealer didn't help, he called the factory in New York and found out about a wider idler pulley to fix the problem. Dealer installed it and no more thrown belts.

    We had only changed the belt on our 3100 a couple of times in over 700 hrs.

    Our 2000 is a different story, lots of belts on that one.

    Our problem was gum balls, off sweet gum trees, getting between the belt and pulley.

    We called Ferris and were told they make a "belt keep kit". They gave us the part #, had our dealer order one for each ztr, solved our problem.

    a belt keep kit huh?

    My experiences with the factory have been awful.

    1) they treat you like you have no idea what going on

    2) you get the sense they don't want anything to do with you.

    3) there is just a general distain for you, like you are bothering them


    The dealer however is great, but I get the sense they are new, or don't sell that many, so they don't know everything.

    I have three Evolutions (a 52, a 48 and a 36) of them all the 36" is the fastest machine (which doesnt make any sense it has smaller motors, pumps and tires) the one Is3100z we have we call the "Fat Lady on a water bed"
    It's slow, rolls around almost uncontrollably and you feel like you are just riding waves all the time.

    Anyone have that fat drunk feeling on one of those? Or any issues with weird speed variances in models?

    Our biggest problem is no dealers in this state.

    Scag dealer is horrible, so is the john deere dealer.

    The toro dealer and the gravely dealer are "I can order anything you want" kind of dealer, with no showroom machines, no demos and no dedicated mechanics/techs.

    We went with Ferris because they guy in Minnesota treats us good, as we have gotten heavy equipment from him, and he can order anything we want just as fast as the guys in this state can.

    I don't understand running a dealership with no inventory, thats weird, but it's alaska....

    I spent a summer with the factory through email and phone calls, the machines we had were not running liek they should (and still dont)

    How new is the machine? What color are the belts you are having problems with? There have been some issues with some of the belts. I would have to look back through my notes from the dealer meeting a couple months ago to find the info. Something about the cords not being evenly spaced inside the belt causing it to roll off easier and also break easier. I believe this was only a problem for the newer ICD deck belts.

    Might be something to ask your dealer to look into for you.
