If the engine is a direct injection engine, it is abnormal for it to be hard to start, even cold. I own a L2250 (about '87 model) that starts at the turn of the key. This engine starts instantly ("with authority" as I've heard it described)and settles to a smooth idle. I'm not diesel mechanic, but understand that if it starts with white smoke there can be injector or compression problems.

800 hours is low for this age, and if accurate there could be fuel contamination, clogged filter/lines, suction lines leaking air, etc. I don't know if you are looking at a dealer or individual, but I would be relatively sure of the repairs needed before I paid full value for it.

As Bird said, You will get many opinions on this subject. I think the fact that most of the newer mowers come with a flexible link connection at the top infers that the height at the front should be set with the lift links on the 3 PH.

I also agree that running the mower higher in the front will double cut the grass. In some cases this could be advantagous, such as mulching tall grass (cutting it twice) for a better look. I personally like to set the mower as level as possible when mowing established grass. The passing of the rear of the mower has another chance to better trim the grass cut by the
blade(s) as they circle at the front of the mower. Cutting rough brush I set the front lower.

Multi-viscosity oils were explained to me by a respected oil distributor as having pollimers(sp?)added to provide the characteristics of oils at both ends of the viscosity spectrum. The downside of the pollimers is that they are not lubricants, so any of them added to the oil are displacing lubricating oil. His statement was that it is better to stay with a single weight oil if you change to the proper weight as the weather changes. He also said that the wider the viscosity spectrum (ie 10w40 wt), the more pollimers have to be added. His opinion that a 10w30 was better if you use a multi-viscosity oil.

Of course, with the average vehicle owner unlikely to change oil with temperature changes, the advantages of the multi-viscosity oils being near the right viscosity for all seasons to get the oil flowing early to decrease startup wear is considered to outweigh the additional lube qualities of the single weights.
