Taylormike Posted November 4, 2016 Share Posted November 4, 2016 I might have an opportunity to purchase Ford 640. Good tractors? Quote Link to comment Share on other sites More sharing options...
wolc123 Posted November 4, 2016 Share Posted November 4, 2016 Not bad tractors and easy to find parts for. The hydraulics can be an issue. Those were early versions of Ford's "live" hydraulics and it took a few years for them to work the bugs out. The live hydraulics and pto make it a good bush-hog tractor compared to the earlier N's. Check for good oil pressure, compression, clutch and rear tires (new fronts are cheap). See if the hour meter works (less than 200 hours would be great).

landtracdeerhunter Posted November 18, 2016 Share Posted November 18, 2016 The 640 had an original vane style hydraulic pump that failed due to people not removing the 3 point housing to clean the bottom of the hydraulic housing, as they had no hydraulic filter. Some have been converted over to the later 641 piston pump. This pump is a better choice. Live power take off was available on later models but had to be ordered by the dealer. Most farmers wouldn't pay the extra $300 or so at the time so most don't have it. The 640 had a 134 cubic inch motor that needed all the radiator space for cooler and will not withstand much plugging. 1 Quote Link to comment Share on other sites More sharing options...
