Kohler XT675-2015 21" cut

Anybody knows what the rpm setting for this fix speed engine is? I can't find anything in the service or owners manual on what it should be set at. This is currently only idling due bent adjust setting. Kinda stupid of Kohler to hide this spec.

Pie Are Squared? (blade tip speed) I would guess around 2800-3200 RPM

The description on Kohler Plus says 3100.

Okay I search blade tip speed and found an old Tecumseh service bulletin indicating max tip of 19,000 ft/min. Is it still at 19,000 or have they lower it again? If still 19,000 then then I need to set at 3400-3450 for 21" blade.

The description on Kohler Plus says 3100.

Thanks I see if that works but it appears that I can increase to 3400 if needed and still be safe.

Yeah fairly sure is 19K fpm and rotation must stop within 3 seconds of OPC release
