I just purchased a 48/18 Fastrak. After reading the owners manual I went to the garage to mess around a little. The manual instructs me to ONLY engage the deck clutch with the engine at low rpm. When I do this it promptly kills the engine. So I try a little higher rpm...kills the engine. I tried it all the way up to full rpm before it did not kill the engine and it nearly does (kill engine) at full rpm. Is there something wrong or is this normal (i hope not)? I do not remember it doing that when I demo'd it. I tried to reach my dealer but he is at a farm show so I figured i would try here. Thanks.
