I currently run a 48 bobcat/kaw 13 with a sulky. This is strictly for my own personal use. My friend sold his lawn contracts to go into pavers. We just moved to a 2+acre lot with lots of trees. It is taking 3+ hrs to cut and the sulky is killing my back. Today I saw a 2004 JD 373 54" Kaw 23. The unit has 370hrs. $4950 Yesterday I looked at an Exmark Lazer XP/54" Kaw 23 new $7800 Both dealers have been in business for a long time and both offerred demo's. There seem to be alot of JD haters on this board. My neighbor runs a Exmark for his business and loves it. If you were in my shoes.... which would you choose. Are there any negatives to the 737 or the 7 Iron deck??? I have read that the Triton Decks have had quality issues. I want nice stripes and take alot of pride in my lawn. The walk behind has a great cut... I guess I'm getting too old for it.
