3 pt lift has 5 second delay

Rudevette · Mar 1, 2012

So my Bobcat Ct235 has about 150 hours on it now. It is a couple of years old. :confused2: I changed all fluids and filters at 65 hours and everything was fine. This morning I ran 3 miles down the road doing some snowplowing, a little blowing, etc. to get the road opened so my wife could get home from work. Everything worked fine. Tractor was about out of fuel so I parked it by the house and went to town to get fuel and take care of some business. When I got home 5 or 6 hours later I fueled it up and started it, jumped on it and blew snow back aways. Then when I went to lift the blower it didn't lift. It takes about 5 seconds, then I hear the pump make some whining noise and the blower lifts. It drops just fine and the drop speed adjustment knob is not the problem because it makes no difference where it's set. The rear hydraulic remote is hooked up to the chute rotator on the snowblower and it works perfectly. The loader works perfectly. All are fast and responsive. It's just the 3 point that is having a problem. Can anybody help me out here?

Thanks,
Justin

Do you have rear remotes? Check that they are not in the detent position.

The rear remotes are hooked up to the chute rotator and are working perfectly. If they were in the detent position the rotator would be all the way to one side or the other.

The drop speed adjustment knob (between my legs by the floor) makes no difference where it is set. It does what it's supposed to because the drop works fine, it's raising that's the problem. It's set somewhere in the middle now which is a pretty fast drop.

I sent you a message on the KIOTI side too. I know you dont think it is the MLS Valve (valve btwn feet) but there probably is a piece of trash in it. I have pulled 3 apart, all three having different symptoms, one being yours. Clean it completely, every part has to come out. You may never find the trash unless you wirk on a White cloth.

Once you remove valve you can look up inside tractor and make sure linkage in transmission is functioning properly. There are adjustments in there. Dont make any adjustments without having a book.

Schematic - Hydraulic fluid travels from tank to pump to joystick to aux remotes the MLS Valve/3-pt hitch cylinder.

After reading this post, doesnt soumd like you are getting air before the hydraulic pump as I stated over on KIOTI page.

Well that sounds like fun. I'm good at that kind of thing. I rebuild automatic transmissions for fun.:confused2:

Remove seat and look down. You will be looking at it. Pull the valve out and look up inside and see if something is broken or loose. There are some adjustments - be careful nothing falls into bottom of transmission case. look at linkage good.

Pull the MLS valve apart. Lots of springs and balls - I believe 3 ports that need cleaning.

P.S. I hate automatic transmissions... Nothing fun to me about them except when they operate properly!

For those following along please go to my post on the Kioti forum. That way I don't have to do this all twice. I am going to the Kioti forum because there seems to be more owners over there since the brand has been Kioti longer than Bobcat.

I took that MLS valve apart today again with a local mechanic watching me and we looked over the linkage and the MLS valve together and both agree that we see nothing wrong.

I spoke with the service departments of the dealers around here. There are 2 of them. Either one is multiple hundreds of miles of hauling to get the tractor there. Neither one of them had any idea what to do. And I was wrong about the hours on the tractor. It has 120 hours, not 150 hours.

Adding all that up I've decided that the lifespan of these scrap metal tractors is 120 hours then they're shot. It's going to cost me $200 in diesel fuel alone to haul this worthless piece of junk to the dealer then there's no guarantee that they can fix it either. I am taking it to my local Kubota dealer to see if they will either sell it on consignment as is or take it on trade for a new Kubota or New Holland.

Lesson learned. It was expensive school.

All this because there is currently an unknown 5 second delay in the 3 point lift? Anything else wrong with the machine? Maybe you should breathe and count to 10.
