I am looking at a John Deere 2040 and a Ford 3600. Need some help on which one to buy, both are diesel. John Deere has about 3000 hrs and Ford 600 hrs. John Deere is $3500 runs good but has moisture in the hydraulic fluid. Ford is $4000 and runs good and seems to be cleaner than the John Deere. I will only be using the tractor for running a brush hog on about 10 acres about 4 to 5 times a year. Any help would be greatly appreciated.
