    Scag 52" V Ride, 2017 model with the Kohler EFI. Yesterday when I was mowing, the mower chugged hard, when mowing thin grass. I had no issues getting it to the trailer. Belts tight, oil is filled appropriately, etc. I then started the mower while on concrete, full idle, no problem. Engage PTO, mower kills it's self as it doesn't have enough power. Any ideas on what it is?

    maybe a coil went out and it's running on 1 cylinder. that has happened twice on my kohler engine.

    No diagnostics on EFI engines?

    should be a check engine light on while it's running if it's one of the coils.

    I had a similar problem, surging & almost dying when engaging the blades on a 17' v ride with the efi. This was when it was less than 10 hours so may not be the same issue, but the dealer had to reset/reflash the computer to fix it. There was no engine light on
