Question about Husqvarna Garden
New pulleys, towers and belt. Mower runs at good idle but blows black smoke and cuts off when PTO is engaged.Quickly disengage the PTO and engine will continue to run. idler brakes open fully when PTO is engaged.
Sounds like the seat safety switch is not working. Check to see if both wires are connected to that switch. If they are.. then disconnect them, jump them together and see if mower runs Ok

Frozen idler pulley under the tractor frame or frozen or damaged bearings on the deck spindles. With no belt tension on these items they should spin freely. If you have the know-how you can fix the problem yourself (parts are available at sears.com or elsewhere), otherwise you will have to bring it in for repair.

at the point of lowering the pto it's trying tosuck more air to mix with the gas .you might just need to change the air filter.

Most likely what you did was burn one or more spots on the belt. When the blades and belt stop turning, like in tall grass, the engine doesn't stop and will burn flat spots on the belt at the engine pulley. Every time the flat spot hits a pulley, it will jump and can set up a bad vibration. Run your hand around the sides of the belt or take it off and you will feel or see the thin spot(s) on it. Replace belt.

i'm wanting to install a mulch kit too but it seems diffecult. hoew do you access under the mowing deck to install everything?

did you try depressing the clutch to disengage everything regardless of being in neutral? and it sounds like a pulley bearing went bad.try to spin the pulley with your hand and see if it moves.take the belt off to the mower deck and that should keep them from turning when you go to start it.

Place the deck in the lowest position using the hydraulic piston (if applicable) or the manual cutting-height adjuster.
Remove the deck-to-PTO belt from the PTO by releasing tension on the idler-arm pulley. This is a spring-loaded handle that turns in only one direction by hand and relieves the tension on the belt. Slip the deck-to-PTO belt off the PTO pulley after the tension is relieved.
Remove the deck from underneath the mower or tractor.
Locate any belt stops and loosen them with the ratchet wrench and proper socket. Belt stops are located on the deck and are the small metal brackets that guide and secure the belt to the pulleys so it will not jump off when under heavy use, or stretch from normal wear.
Remove any pulley covers by removing the retaining screws using the ratchet wrench and a socket.
Loosen the idler-pulley retaining bolt (located on the underside of the mower deck) to replace the deck-to-PTO belt. Removing the bolt is not necessary. Loosen the pulley enough to wiggle the belt free from the pulley and remove and replace the belt.
Remove any arbor covers (if applicable) that conceal the arbor pulleys by removing the retaining screws with the ratchet wrench and a socket to replace the mower arbor belt.
Locate the tensioner pulley on the mower arbor belt to replace it. Loosen the tensioner pulley bolt enough to slide it and release tension from the belt. Remove the belt from the arbor pulleys and replace it.
Slide the tensioner pulley back leaving about 1/2-inch of play in the belt and tighten the bolt. Reverse the procedure to put the rest of the mower deck back together and reinstall on the mower or tractor.
