I recently purchased a Scag Turf Tiger 2 with the 61" V+ deck and Vanguard 37hp EFI. This is the first EFI engine I have had on a mower. The dealer dropped it off this morning and the only time I have had with it so far is just moving it from the spot they dropped it off to 30' to the garage. The one thing I noticed is that the throttle is either idle or full throttle. It didn't seem to half any corresponding throttle positions through the range of the lever. Just curious if this is normal? I bought it mainly to mow our property but will be looking to mow part time with some residential and a couple commercial properties as a solo operator.
