Loader float function

[kenmac]

Just got a new (to me) MX 5100. The loader doesn't seem to have a float function.
Is the loader float function an option on Kubotas , or is mine just screwed up ?

 

[whirly]

All Kubota loaders (L844) on a MX5100 have a float function.

When the engine is off, try pushing the joystick past the detent as you push up. It just takes about 10-15lbs of pressure to override the detent.

 

[DieselBound]

If you push on the joystick until there's resistance and then just pop/snap it (more forward) that'll punch it past the detent and into float mode. If the lever pops off then you're in the "broke" mode :laughing: (no, you will not break anything unless you're doing something VERY wrong)

 

[kenmac]

ok, thanks. I'll try pushing it a little harder. On the loader on my other tractor, I don't have to push very hard at all.
I had dealer install a 3rd function valve and didn't know if this may had affected that function.

It's not uncommon for the float detent to get jammed up for a variety of reasons (sometimes water gets into the can and rusts up the parts). So if it doesn't easily go into float you may want to unscrew the can at the bottom of the valve and inspect the detent mechanism. There are usually ball bearings and springs, so try to study a parts diagram first and be ready to catch the parts if they want to jump out.

Springs & ballbearings mean it explodes when opened. Put a bag over it before you finish pulling the cap off so they don't go anywhere hard to find.

I didn't realise that I had a float function and complained when it was serviced that the lever 'jammed'.
After the serviceman explained what it was I then broke all the rules and read the instructions

I know on most new tractors, that float function can take some effort. After it is broken in, it's rather easy to get it in float.

A regular and often post that is usually corrected when the stick is pushed/popped further so it goes into float position. Stiffer on some Kubotas than others and once the action is done a couple of times most people don't think it's that hard. Some are just afraid to break it.

I couldn't get it on mine either. Quite stiff when new. It's either loosened up our I'm just used to the force required.

 

[kenmac]

well, I pushed it pretty hard today and the entire loader valve was moving. It never felt like it was moving a detent ball. It seems to stay in a float position if I hold forward on the joy stick , but as soon as I let go, it goes out of float. Guess I'll try to work on it some more tomorrow and see if I can get it to stay forward in the float position

 

[kenmac]

ok, I went out just now and tried the float function. This tractor was used ,and I didn't check the float function when I tried out the tractor (my fault) Anyway, The joy stick does go into float, but it won't stay there on it's own. You have to hold it there. as soon as I let go of the stick, it goes back into regular function.

I guess if I want it to stay into float without holding it there. I will have to take it to a dealer for a new loader valve ?

Chalk this on my screw up for not checking B-4 I bought it

Mine stays in the detent until I take it out. It could be you just have to work it with the hydraulic oil flowing and see if that cleans it out. There is a spring on the detent ball and if you had to push hard to get it into the detent position then there is likely some corrosion or sediment around the spring.

Appears the dealer added 3 function did a neat job.

Anyone got an after market # for the HST filter ? I was able to locate the Hydraulic filter buy not the HST filter

Looks good, I just use kubota filters the hyd has a magnet on it

Thanks, I'll keep playing with it to see if I can get it to stay.
I really didn't have to push hard to get it to float. it just won't stay there. I don't thing the 3rd function had any affect on the function ,but I didn't try it before I bought it, so I don't know.
Like I said. it will go there ,but you have to hold it there

well, I was looking for after market filters. I found them for the HYD, but not HST.
I removed that magnet and installed it on the new Baldwin filter

The HST filter is just made for kubota and no cross reference it happens with filters , My wife runs a parts department for a equipment company, I looked too

well, crap.. How often do you change it ? 380 hrs on the tractor

 

[Peter 315]

I changed mine at 50h and 300h hyd oil to because i got free oil, Did you get any books with the tractor
