I'm looking at getting more commercial units. I can't afford new ones right now but found some used ones. I'm just wondering what some of yall think about hour life and price on these. 2013 models Exmark and Toro Pro 6000 with around 1500 to 1800 hours. Prices are around $4950 to $5500. Any thoughts on these or another direction I may consider is greatly appreciated. Thank you.
