I am interested in purchasing a Kubota TG 1860G with about 800 hrs on hourmeter. Aesthetically looks good. I have heard there were lots of problems with the belt system and they needed to be changed frequently. I also heard something about a plastic cam gear in some of the units. My question is, are these units of good,dependable,long lasting service type mowers for 1-2 acres of flat land with good maintenance being performed. I have owned a Kubota BX 1500 and currently have a Kubota G2000S that is wonderful. I have always believed that Kubota has good products but have concerns regarding this unit. Please comment if you have experience with this unit. Thank you.
