This 56 hp 5203 MFWD (4-wheel drive) with loader replaced my old 5200 2-wheel drive. Same great performing tractor. However, the 5203 is far more capable but has had some problems.
Rear hydraulics leaked on delivery but was corrected by dealer (AG Power of Mineola). Cold start sensor failed at 200 hrs, blowing a fuse and prevented starting. One $30 sensor and .30 cent fuse later it was fixed.
My only complaint is control ergonomics -- the 4wd lever, PTO lever and ABC shifter are too close together, making it difficult to reach the 4wd lever when the PTO is engaged. Other than that it's been a great tractor.
