A local township, 3 miles from me just outside my city, is solicitating bids for a 60" ExMark Lazer Z. The ZTR is two years old with 150 hours on it(just used to mow the lawn of the township hall and township country park twice a week-roughly 1 1/2 hours per mowings) and has a 20 HP engine. Now my question is, is the engine too small to be used as a commercial mower? It seems it should be at least a 23HP model on the 60". The township gets a 20% discount off the top from ExMark using a township discount that ExMarks gives to rural municipalities but Im afraid they give them lesser power since they are just mowing one flat surface at the township hall and park. Now the minimum bid is $4500. They can trade the mower back in every 2 years for a certain price, the price is $4500 so they start the bidding process at this number to not lose any money. If no one bids on the machine, they just turn it back in at $4500 and get a new mower. I would like to bid on the machine, saw it today and it is beautiful, seriously looks like it was just taken from the warehouse. However, I would feel better if it was 23-25-27 HP for the fact this would be strictly a commercial mower for me and the commercial land in this area is very rough. Thoughts?
