Hi Rich, we owned a 674D for a few months and traded for a newer model 684 with T/A. There was nothing wrong with the 674 but it had the slow speed transmission without T/A and for our JD forage chopper 2nd gear was to slow and 3rd gear was to fast. 684 is a newer model but it had faster transmission and 2nd gear was just right and T/A for heavy spots. My brother still has 684 and it has almost 7000 Hrs on it. The D239 German built Diesel is a very good engine and it is used in a few other models like 544. 674 is about 62 PTO HP. The everything from the clutch housing back is common to 454,464,484,574,584,684,784,884.

Weakest point is the parking brake. Usually the parking brake warning lamp on the dash burns out then someone drives the tractor with the parking brake engaged and the brake band in the transmission gets chewed to bits and the bits get into the hydraulic system and the bits clog filters and MCV valve ports.

So check to see if parking brake will hold tractor on an incline. The other thing is if it has T/A. The T/A should not free wheel on a downward slop in Lo on this model.

Don't know price of 674 but good 684s were going for near $10,000 CND.

Good luck
JimB
