hydraulic slippage

[anthonyk]

I've got a Century 3647, just turned 50 hours.
I did the service myself, essentially change the oil, filter, and hydraulic fluid (took a LOT more than I was expecting)
Everything seemed fine for a few weeks, but lately, when I first start it, and try to raise an implement like my bushhog or box blade, the implement seems to slip. It'll raise and lower okay, but if you hold it at a certiain height, it sort of slips and raises about an inch or two, repeatedly. After a few minutes, it stops, and everything seems fine.
I've checked the fluid using the clear gauge and it shows full.
It has gotten colder lately, but I'd be surprised if that's it.
Any ideas/ suggestions?

thanks, Anthony

Check the knob below (it is down alomost to your feet) the front of your seat. Try turning it in. It comtrols the speed that the 3 pt hitch goes up.
Happy Tractoring

Anthony,
I have a similar problem on my Branson 3510 - see this thread . Headed to the dealers this morning. They picked the tractor up yesterday.

thanks, I read your links. what was the upshot?
did you ever get it resolved?
last post said your dealer thought it was junk in the fluid, (which doesn't make sense to me).

what finally happened to correct it?

thanks again.

Anthony,
Check the latest on the other thread. Upshot is that it is working fine at the dealer. Told him to keep it until Monday to be sure it's not gonna be a problem later. Wish I knew what was happening - so does the dealer and all of his mechanics. Don't you hate when "it behaves for the dealer"! Hopefully yours will straighten itself out as well.

Anthony, have you tried just working your hydraulics to their fullest extensions ....several times? EG.... if you have a loader, move it up and down with all functions to their extreme limit. If just a 3 pt hitch, make sure you raise and lower it multiple times to full extension and back. Keep repeating this till you get tired of doing it.

I am saying this, as a yr ago I had the same issue when I changed out a backhoe and put on a rear blade. Also, the weather was real cold, which may have played a part in it. I had to unhook hydraulic lines, and then rehook them. I simply worked my hydraulics multiple times, and have not had the problem since. I always thought it was related to the change of hydraulic lines... (possibly introduced air into system maybe?). Don't know much about hydraulics, but the above worked for me.


Sage uncle Virgil at the time, said to replace seals in the 3 pt hitch...that this was a fairly easy job for the dealer, and thought that was the issue.

my 2 cents....

thanks for all the tips, I'll try moving the hydraulics up and down, I wonder if that has the effect of bleeding the lines or something.
Of course, it's raining today, so it'll be a day or so till I can try.
Keep ya' posted, thanks again.

I am watching this thread with interest, as my Branson my have a similar problem. Nothing serious, i'm sure, and probably caused by user inexperience:

With an implement on TPH, if TPH is raised all the way, every 20 seconds or so you can feel a little jerk as the implement loses and recovers about a half inch of height.

If I move the lever down two inches the implement stays put just fine.

Well, I did everything everyone suggested. Followed Chippermans advice and tried varying the speed with the speed control knob. Then I raised and lowered the box blade a dozen times or so. Now the darn thing is working fine. It has also warmed up considerably. (snowing last week-today 75 degrees- go figure). I don't know which of the 3 was responsible, all I can say is that it seems to be working fine. Keep ya'll posted and thanks for all the tips and advice.
