My GT245 has a 20hp Kawasaki engine and seems to run quite slow. Full throttle rpm seems slow to me. Is this normal? What can be done to speed it up a bit?
Hello, welcome to TBN. "Seams" is a little subjective. I would first start by buying a tachometer. You should be able to buy one off ebay for less than $10. With it you'll actually know what speed your engine is running at and if it needs adjusting.

I believe the foot pedals are adjustable for a little further travel. Under the tractor there should be a threaded linkage for adjustment. But if I remember correctly, the more forward travel introduced to the pedal, the less travel and slower the backup pedal will engage.
