My John Deere 4400 Compact Tractor came with an excavator and no 3 point hitch, so I bought a kit from Neat Farms a few years ago but the arms were too short and were cutting into my rear tires. I finally got fed up and ordered these arms. They're 4 inches longer and I can finally drive around with my Bush Hog Model 600 in the air. I think they are exactly the same size as the factory JD arms, but a fraction of the cost. I am VERY HAPPY NOW.
