I have a JD 70A loader on my 955. The spec sheet in the manual states the following cycle times:
Loader raising time: 2.8 seconds
Loader lowering time: 2.4 seconds
Bucket dumping time: 2.5 seconds
Bucket rollback time: 2.1 seconds
(times measured using a 48" bucket... I have a 60" bucket)
Bucket cycle times are good, loader lowering time is good, but the loader raising time is slow... about 6 seconds. I checked all of my hydrualic lines and none of them have any restrictors in them. That got me to thinking that maybe the issue is in the SCV, so I switched the two loader hoses at the quick connects and operated the SCV backwards (moved lever to the lower position to raise the loader and vice versa). Loader raising time is still slow and loader lowering time is still good. Anyone have any bright ideas as to what is causing the slow loader raising time?
