Well, you remember last Spring when you asked me how warm & how noisy my pump reduction was? Where I had it set to exactly half speed, it was whisper quiet & the reduction was barely warm after a 5amp batt... then I tried it at about 80% speed for 8-10 minutes & I think I burnt my finger when I touch it!
It was still whisper quiet then, but the next day or two later it wasn't... and continued to get noisier with each later use. I probably don't have more than 2hrs on it since Spring b/c I just hated its erratic hydraulic movements b/c of too much flow & I like my JD850 so much more.
Hopefully this 30% reduction of flow will make it more fluent in motion.
