2000 Lawnboy 10525 with 3 speed gearbox - when drive engaged , belt " chatters " . Cable adjustment seems correct . When disengaged , nothing feels loose . Any suggestions ? Thanks BTW , this is my first Lawnboy , used a Toro with the Suzuki motor for 25 + years , got a tractor , and sold it . Ended up missing the 2 stroke , got good deal on two 10525 . Duraforce and Suzuki seem very different ( to me ) .

Did you inspect belt....stiff or cracked may be the issue or maybe the pulley is loose/worn.

Thanks for your reply . I did check the belt , but not for those things specifically , so will check again . I detected no movement in the pulley .I did find that the stepped washer that seals the plastic dust cover by the drive gears was in two pieces . Installed a new one , have not tried it yet , but I don`t think that was the chatter cause . Thanks again
