Mower is the Swisher ZT 2660 runs great. Blades slow then stop during cutting, I changed belts (drive & deck). Last year you advised it maybe the electric clutch. Question is that a do it yourself job??? What do you think it may cost at a normal repair place.

YOU MAY HAVE A BENT BLADE OR EXESSEIVE BUILD UP UNDER THE DECK

SOURCE: Swisher 60 deck belt breaks after mowing about 15 minutes.

Even though the routing is correct, have you checked that every spindle and idler pulley turns freely? These bearings can freeze up or bind because debris builds up in them. Also, if the bushings on the idler pulleys can wear, causing them to misalign. Keep checking. Also - is the belt snapping clean, or do you see a burnt, worn spot?

Testimonial: "Thank you for your help. The belt is snapping clean. You are correct in your assessment to what the problem might be. We checked all the above and did not correct problem. We put three washers on top of small idler pulley to bring it down and better align routing. Bought heavier belt at auto parts. Believe the bolt head was touching belt where it routed throught to larger idler pulley."

Check the all wiring from the engage blade button back to the electric clutch for worn spots that may be grounding out on the frame.

Is the belt slipping? If it's slipping you'll notice it, because it'll smoke pretty soon. If, as you watch it under varying load, it slows down with the blades then the belt is fine.

If it's not the belt then it's going to be the electric clutch that drives the belt. Get your voltmeter out and tap into the wires that go to the clutch, watch it as the mower runs. Anything under about 13V and the clutch may slip. If the voltage is good then the clutch is worn out. They don't cost too much, I'm pretty sure they're well under $100 still.

Make sure the wires that plug into the clutch are making a good connection. You want to check the voltage between the switch and clutch so that you're also checking the switch- if it's got a little crud in it, or a bad connection farther up the line, it can cause the clutch to slip, and you'll see this as the voltage dropping.
