I have just purchased a new LS185. This is the first time I have owned a New Holland. The last machine I owned was a Thomas LS173 I thought this would be a big step up. Especially when this machine is rated at 7000 brake out force. I was very disappointed vertical lift is 2500 and it will do this but any more puts it into bypass. The first day I tested the machine I tried to flip a bolder I was very close to moving with the 173. The 185 would not even budge it . The dealer tested the hydraulics and said all were in spec. Is this normal?
