Thanks everyone for your comments. The tractor is in great shape - except for the engine. It has a 50 inch deck, which from what I glean from reading posts on these tractors (and other similar models that use the same deck) that it is one of the best mowing deck Simplicity ever offered.
I came within a hair of buying a Simplicity Sovereign back in 1998 when I bought my first Wheelhorse tractor. I went with the Wheelhorse because my FIL had one, I bought a '97 year model - the last with the cast iron Kohler magnum engine in it and the Simplicity was about $1,000 more expensive. These Landlords were being sold along side the old style Sovereign's - which were the bread and butter tractor even back during the A/C days. I really like my Wheelhorse tractors and when I branched out (just for kicks) and wanted to try the Simplicity and Cub Cadets - just to see what they were all about, I found a Sovereign - which I have now.
I consider this Landlord DLX a more "modern" tractor. By that, it has foot controlled hydro and for my Wife and Kids, a very easy tractor to start and safely operate. I just need to get an engine in it.
I found a donor engine that may fill the gap in a free tractor I'm going to try to pick-up this weekend. It is a 14.5 hp engine vs 18, but if I can get it to work (and it's looking promising) then at least I can drive the tractor around and do some light mowing.
Dennis - you are right that Simplicity tractors give a great cut and stripe with the rollers across the back. What most don't know is the Wheelhorse deck is basically the same - both are ground supported and follow the terrain. I've mowed with my IHCC 109, and it does a good job, but on my lumpy and somewhat sloped yard, the side to side cut can leave something to be desired - if you are looking for a 100 point cut. My Wheelhorse tractors give a great cut - just like the Simplicity IMHO, just not the stripes.
My Dad bought a zero turn mower I believe about 6 or 8 years ago and after about 60 years of using a steering wheel, he just couldn't get the hang of two levers on the zero turn. He sold it and bought a Simplicity Prestige, which is similar to this Landlord I bought - but heavier build IMHO. It has power steering and a diff lock. It was his retirement present to himself after fussing with push mowers and lawn tractors with tiny wheels that constantly would spin. He is a happy camper.
Not in a hurry to get this tractor going, as with all my tractors, there is a limit to how much $$$'s Momma will let me spend without getting grouchy and I look at the back log like unread chapters in a great book - waiting their turn.
