Ok , I love my Massey 1529, about 14 months old,but the bucket wont stay curled full or empty, and the loader arms drift down as well.Is this normal for a tractor? Im in construction so Im used to loader and backhoes with buckets that stay put even under load. At 1700rpm with bucket full of firewood,24"off the ground,fully curled,it takes about 8 minutes to lose 3 " of bucket height and uncurl to the level indicator on the bucket. I notice also driving a distance with a loaded bucket it will slowly uncurl as well. any input? Thanks in advance!!
