I've got two 60" ZTR's coming to demo on Monday; the Scag Turf Tiger and the Exmark Lazer Z LC, both equipped with the 27HP Liquid Cooled Kawasaki. One will go back to the dealer and one will stay here with me; both are brand new.
As I visited the Exmark dealer this morning, I drove the machine around the parking lot and wondered about the break-in period. Since the machine is run at full throttle to mow, how do you break it in properly? I broke in a new 70HP Yamaha outboard on my duck boat this year and it had a specified period at which I ran it a various throttle settings until after 10 hours I could go full throttle.
Anyone know the recommended procedure for the 27 Kaw? I forgot to read the manual at the dealers so I'll obviously do that on Monday, but the dealer just told me they let it idle for a while at reduced throttle in the parking lot. The thing I noticed was that at full throttle the engine had a 'wave' or thrumming sound--in other words at lower rpm's it had a steady, even sound to it, while at full throttle, not moving, it had a slight up and down tone. I hope that makes sense but it's hard to describe any better than that; since there isn't a tachometer on it I couldn't tell what the flucutation in rpm's was, but if there had been a tach I'm sure there would have been at least a noticeable variation. The dealer said it was probably due to being a new engine and having pollution control devices on it, but that he'd make sure it was adjusted correctly on Monday.
Can any of you guys give me some break-in tips and experience for these mowers? Thanks, Will
