Checking to see if anyone ran into a similar problem as I'm having. Last weekend I mowed with my Craftsman Garden Tractor (G5000 series with 24 hp Briggs, hydro gear g730 trans). Very hilly yard, about 215 hours on the tractor. Problem I'm noticing- full power, blades engaged, going up steep hills, the tractor will vibrate/shudder and lose forward speed. If I nurse the pedal slowly it happens less but still happens. Engine pitch/speed stay the same, so I believe it's something after that. Anyone have something similar happen? I'm on the road but want to start diagnosing as soon as I get home. The grass is growing fast in TN!
