I have a Hustler Sport that is about 10 years old. It clogs with grass often which. The PTO clutch burnt out recently and I replaced it. The first time I used it, it clogged after about 10 minutes of cutting, but I didn't notice immediately. The belt kept turning, because the electric clutch was still engaged. This meant that the belt heated up and started to melt on of the plastic idler wheels, and smoke started pouring out of the mowing deck.
My question is, what is supposed to happen if the blades get jammed with grass? Is there supposed to be something that automatically disengages the clutch if the blades jam, and if so, what is this mechanism? What seemed to happen before I replaced the clutch was that the blades would jam, the sound of the motor would change slightly, and I would disengage the clutch, but there was no smoking or burning of the belt, because it seemed to have stopped being driven. I don't see how the PTO clutch is supposed to disengage automatically, because if the coil is energised (the switch is on) the drive pulley is engaged.
Any help is appreciated.
