I purchased a new lesco 36" last week and the lowest it will cut is 2.75". For some reason the engine is mounted to the lower holes. I'm a little worried about having them fix it for me seeing the guy who showed me the mower had no clue how the thing ran. He actually told me that it was set up for a 3" cut when it was actually set up for a 4" cut. He also told me to only run the engine at 1/4 throttle when cutting (????). I'm thinking about remounting the engine myself rather then let them touch it. I'm cutting at 2.5 rite now and work my way up to 3.25 and then down to 2.25 in the fall. Why would I want a mower that only cuts as low as 2.75. Am i missing something or is there a purpose for setting up the mower up like this?
