Hello, I am looking at buying a bobcat 720. However, it makes me nervous since when the controls are moved there are loud noises ,,the same noises as it makes when the controls for the aux hydraulics are moved. (the aux hyd are deadheaded, nothing hooked to them) Also, when operating the machine, once in a while the control levers started to shake in my hands,,??? I have very limited experience with skidsteers,,but lots of experience with forklifts,,and a hydrostat drive Lull high reach forklift..none of them have ever made this much noise under any condition....also,,my 580ck backhoe, which is very old and tired, makes very little hydralic noise,,, The dealer who has this machine says the drive motors were recently "gone thru"... the machine seems to function,,but feels ,,,uncomfortable,,,,jerky,, Any thoughts from you guys who know? cause I dont!! No experience,,from indiana,,lol Thanks!
