Snappy Hydro in JD

[LBS]

I have a big JD (I do not know what model) with a 18Hp liquid cooled Kawasaki that has a very snappy hydro, it is a Sunstrand and it looks smaller than the Sunstrand in my 7790. Are the hydros in the simplicities supposed to feel about like the ones in the JDs? Or are they more sluggish? Also, the hydro in my 9020 is very 'mushy', It seems to get up to speed but it will not spin very easy, in other words, it has a lot of give to it. Is that normal?

I thought my 716H felt a bit mushy in the hydro department till I changed the hydro oil and filter. I think the fluid was down a fair bit as well. After a refill, it runs much better.

Its also possible the charge pump in your 9020 is showing its years. Is the hydro lift slow on it???MPH

Both my 12hp & 18hp hydros will lift the front wheels off the ground if I'm not careful.
