The next lazer z Commercial unit, 52 deck, 27 or 29 kohler engine (can't remember) demo unit - 87 hours. Dealer wants $7500 for the mower. Full warrenty I bought 4 of these last year. My machines have 600 - 820 hours a peice. I could use an extra. without going to storage unit where all records are kept and digging to find the receipts - it this an acceptable price? My machines have KAWA engines but thinking he said he would give me a hell of a deal on this unit but I don't really think $7500 is a big deal?
