[AT] Need help with newer compact tractor

Sat May 21 09:34:33 PDT 2016

I know some may disagree with me, but the clutchless shuttle shift is a 
hydrostat as far as the oil is concerned.  That is what my New Holland 
TS110 is.  I have a noise when shifting between F&R now that the idiots 
at the Chickasha NH dealer had it apart.  I don't think it is because I 
topped it off with JT-5 when it was leaking at the loader cylinder...  I 
had added over 10 gallons of fluid due to a bad $50 hose on the baler 
that was made at the local NH dealer.  I replaced it with one from the 
Atwoods farm store for $20
