I have a New Holland TN75 and a Kubota 4630(hydrostatic) on my 150 acre farm. The TN75 is a great machine but the Kubota is underpowered and constantly overheats when I am mowing or doing other jobs where it has to run at a constant RPM for an extended period of time. Because of this, I am planning on replacing my Kubota 4630 with a John Deere 5325. Has anyone had experience running this machine? How does the John Deere 5325 compare size wise to the Kubota 4630 and TN75?
