Second Update = Third Review Submission on MF 2660
Model Year: 2011
7/11/12 Since the prior review and one update in 2011: (See prior reviews for earlier problems, since corrected) - At 87 hours in May 2012, the clutch failed completely. I am reasonably sure this was due to the machine having been delivered on day one (April 2011) with a bent clutch pedal arm which conflicted with the console and prevented the clutch from ever fully engaging. At 25 hrs or so that was discovered and the dealer straightened the pedal arm as well as repaired the shuttle shifter linkage. The clutch continued to slip at times and failed totally in May 2012. The clutch was replaced (which, as most know, involves breaking the tractor down in half) in early June 2012. Seems to be okay now at 101 hrs. - At 87 hrs the shuttle shifter lever was going way beyond normal travel and behaving erratically. A roll pin was found partially sheared and was replaced by the dealer. At 101 hrs it operates correctly (maybe for the first time during ownership) and behaves with apparent normalcy. - Having had so many other problems, the fact that the DL250 loader would not force the bucket tip downward by rightward joystick movement had been ignored. In May 2012, I find out that the loader is only guaranteed 1yr. unlike the tractor and has just gone out of warranty. In June 2012, the loader valve was replaced by the dealer and had no effect on the failure to force bucket tip down. Pressure tests confirmed that the problem is in the loader valve body, not the cylinders, yet a new valve body changed nothing. Dealer adjustments achieved slow movement and bucket tip down force only by forcing the joystick hard right into what was advertised to be “quick unload” or gravity drop position. The problem is still unresolved. Another 2660HD was tested and the DL250 on that machine operates properly (or apparently properly since what is “right” on these machines is very illusive). In summary, at 101 hrs. (14 mos. into ownership) all known major problems have finally been corrected except for the odd control problem on the DL250 loader. User Comment: The MF2660 low-profile 4WD performs extremely well on steep ground after brakes were upgraded and fuel starvation issues solved. The center of gravity is nice and low and the wheel separations are about ideal as mounted, with the rears 8’ apart at outer edges. Traction is excellent and power is great. The Perkins engine seems to be a strong point. Having the 8x8 transmission, I would prefer more gear choices close to the hi/lo range shift point. Far too often one is having to stop and shift ranges because the shift point is right at the comfortable operating gearing level when doing brush hog work and pasture clipping. Since the Range shift is not synchronized this is a nuisance. Possibly the 12x12 or some other variant would be better but that does NOT necessarily improve things if the gear ratio at the lo/hi shift point is unchanged. In my opinion the shuttle shifter mechanism is a marginal design prone to failure. Factory quality control prior to shipping is/was apparently terrible considering the initial problems with this brand new tractor. I am optimistic that this will be a great tractor once all the initial problems are fixed. Long-term reliability is the main question now.
Pros: Perkins diesel engine.
Cons: Factory quality control/lack of testing.
