L3130 loses power in high range

[andyd107]

"My 2004 L3130 HST looses power to the point of stalling as i depress hydro pedal in high range and in 4 wheel drive. No problems in 2 wheel and no problems in reverse in 2 or 4 wheel drive. What gives."

Is the Front & Rear tires size ratio correct for 4 wheel drive?

Takes more power to move in high range, check for fuel filter or air filter problem. does it blow black smoke or just lug down? If black smoke, I would start with air filter, if no smoke, I would start with fuel filter. keep us posted what you find.

Also, make sure the brake is not on. Often, with the brake locked on, I can move in low range, but not in high range.
