Just got a new Scag Wildcat with 26Hp LC Kaw & 61" deck. After looking at the owner's manual and engine manual I have the following questions: 1) Break-in period - no mention in either manual. 2) Engine warmup - Kawasaki manual (KM) says warm it up 3-5 minutes before putting under load. I do this all the time with my diesel tractor, I guess it applies to this gas engine as well. I didn't warm it up this much in the first 3 4 hours or so of use. 3) Oil changes - KM says change oil & filter after first 8 hours, then every 100 hours. The Scag Manual (SM) says change oil & filter after first 20 hours and then every 100 hours or bi-weekly whichever is first. Should I go with the 8 hour change per KM? 4) Grease type - SM says use Lithium MP White Grease 2125 for spindles, but "Chassis grease" on every other fitting. Does this mean I have to have two different grease guns loaded? Is this Lithium grease something I can get at Tractor Supply? SM says compatible greases are Mobilix #2, Shell Alvania #2, or Lidok EP #2. I don't know what "chassis grease". I normally use some kind of multipurpose grease for everything, I get it at TSC. 5) Oil Viscosity - The KW shows a chart of different weights to use for various temp ranges. SAE 30 only goes up to 90 degrees or so. SAE 40 goes from 68 to over 100 degrees. Right now its liable to be 55 or 85, and way before the 2nd oil change it will be 95 or more. Should I use 30 weight at the 8 hour change and then change again to SAE 40 when it gets hot? Even 10w30 only goes up to 90 or so, and the KW says the engine will comsume more oil if you use multi-viscosity, and recommends checking it more often if you do. Thanks for any help I can get.
