I have been investigating various mowers to determine which would be best for cutting my 13 acres. Currently I have centered my search to used mowers of less than 1000 hours such as the Kubota ZD328 and NewHolland MC28 front deck mower. I would probably put between 100 and 125 hours per year on the mower. I would attempt to perform the maintenace and repairs. Which type, zero turn or front deck, would generally require the most maintenance and cost more to repair and be the easiest to maintain or repair?
