Something isn’t right. An alignment issue? Rusty pulleys? If there is an alignment issue, the deck could be warped. I wonder if either dealer put a straight edge on the deck surface?

Try the leaking Scag out. If it handles the terrain, think about repairing or replacing the engine on it.

What happened to your owners manual?

Please provide the model and serial numbers. It could be any number of safety switches or a loose ground wire.

ZDDP: Zinc and phosphorus are more than anti-wear additives. They are also anti-oxidants. Higher levels of zinc and phosphorus in engine oils can foul catalytic converters and diesel particulate filters. That’s the reason for reducing the zinc and phosphorus levels in oils for newer passenger...

Whatever! I’ve provided the literature that Kohler and Kawasaki puts out pertaining to their oil. Kohler even states that the demand of small air cooled engines is different than that of automobile requirements. Today’s automobile oils are engineered to meet the current EPA CAFE standards geared...

Your theory is based on anecdotal evidence. An air cooled small engine has different oil requirements than a gasoline powered automobile engine. If they didn’t, small engine manufacturers would not have their branded oil formulated to meet certain requirements...

It’s going to have as much zinc and phosphorus as most other 4 Stroke motorcycle oil or Power Sports oils. Kawasaki and Kohler don’t publish product data sheets. So, take a look at what Valvoline, Mobil, Castrol and others publish. The zinc and phosphate levels are going to be around 1,200 PPM...

If you are bagging, you will need high lift blades. If you have a mulching kit on it, it needs to come off. I don’t know about a skirt kit.

Did you leave the PTO switch turned on?
