Message: <blockquote data-quote="cadman1" data-source="post: 97341" data-attributes="member: 13950"><p>my first time posting here. I just wanted to say that just about everything you can think of has someone who has posted on it here. I will have to say that I have found several that are very close to my problem but I have not found the fix yet. 2 weeks ago I moved my 2003 Bobcat T-190 to my property in NC. from Georgia. I noticed a small amount of creep while loading so I knew the first thing to do once I arrived was to block it up and find the neutral spot. Once that was complete we added some AW32 to the reservoir because I had a small leak from the tilt cylinders. After about three hours of digging dirt and trying to remove an old stump. I noticed that the machine was bucking while simply driving forward. I tried it backwards and same thing. I adjusted throttle, same thing. I elevated machine and readjusted the creep back to neutral to fine tune it. no fix. went back this past weekend to change the filters and case drain filters, no change. while up on blocks I ran through the motions and no problem everything worked good with no surging. All bucket operations work fine on the ground and in the air. once it was back on the ground I did the WAO full throttle in a straight line on level ground. I felt the pulsating of the sticks trying to push back against my hands as it was going forward. I was able to plant my arms on the lap bar and my knees so I could keep the surging down to a minimum because of operator error. I have several thousand hours on a track machine and this problem is very similar to the many times when I have tried to drive and turn on concrete and pavement. I cannot figure this one out . so any help from you guys would be greatly appreciated. I have the old style sticks with foot controls. Also is there a possibility that the AW32 is not mixing well with the AW46. I know the system is a closed loop and it can take a while for it to circulate,( maybe three hours was enough to mix it up) I did not see any foaming and I over filled so it naturally has purged it self thru the vent tube.</p></blockquote><p></p>
