Subject: JD 4020 hyd leak at PTO clutch


Southern Indiana
We have a late model 4020 side console model. The pto clutch is engaged by 2 small hyd. pistons that engage the clutch fork. The 2 pistons leak oil in the clutch housing area. This has happened before each time it is taken apart the o-rings sealing the pistons have a rough spot where it has deteriorated.
Is there a update or something I can do different? This has been fixed 5 or 6 times and it will usually only last around 1 year before it is leaking the same place and is always a rough o-ring.
