    I was wondering if anyone knows what kind of problems I might run into if I was to put a 21-25HP motor on my 48" Turf Tracer HP. My primary areas of concern are: 1) I assume that the mounting bolt pattern would be different on a bigger motor, but I could drill new hole in the engine deck right? 2) do new motors come with mufflers or would I have to find one that work fit? and 3) would it be a bad idea to put more HP on any exisitng component of the mower. For example - could the hydro pumps handle more HP? I know this wouldn't be cheap to do, but more HP should allow me to be much more productive when mulching thick Bermuda grass. I love the mower - just need more power. In addition, I do have another use for the 17 HP motor on the motor if I were to do this so that somewhat offsets the cost.

    Typically when you add more horse power to a unit than it is designed for you compromise its integrity. As far as moving the bolt pattern, I would measure where the crank shaft center is on the frame, to get your belts exact. If the larger engine turns the same or close to the same RPM as the original then your hydraulics should be fine. Most new engines come with mufflers; however you need to find one with a muffler that will not be in the way, or route the exhaust where you do not want it to. Watch your crankshaft size also.
