I have a 2010 3720 with 415 hours on it.
I changed the curl cylinder seals about 20 hours and and changed the trans-oil and the main filter and checked the in line filter. All looked good. The oil was off color as I expected but no chunks in the filter.
Yesterday at 415 hours on it or so, I noticed the tractor will only creep unless I crank the throttle up to 1500 or so. Then it lunges again and runs fine. The next time I turn off the engine and take off again it is the same thing. After the RPMs are up, everything seems okay.
Any idea what causes this. I put in Hi-gard Lo-Vis and the level is up to full. The FEL works fine at any RPMs.
