I was using the fel on my L3240 in float the other day to scrap slush off of my driveway. It would float for a while then start putting pressure down and pick front end up. the lever was still in float. anyone else have this problem?

That sounds as if the hyd valve spool & housing have a little too much clearance or spool isn't getting completely shifted to float position.

I have a b2630 model and I use my in the float position most all the time when plowing snow. Mine has been like that from the start, you have to realize that when you are pushing snow if the snow gets really heavy then something has got to give , what is actually happening is the FEL is still float but the snow it is bringing upon is heavier or lets say more resistance is being met some something has to float so it is the front of your machine . When it gets like this I just drop the FEL down but not into the float position and then it just pushes the snow no problem.

Like I said at times this has happened to me and as I am pushing along and the front of my tractor is off the ground then I suddenly break through the snow and the front of the tractor ,the wheels, come back down on the driveway.

Sorry to say that's not necessarily a problem. It's more than likely a result of the forces being applied to the tractors frame as a direct result of the pressure on the loader.

Trying to put it simply with out getting out the whiteboard to draw it all up, when you apply forward motion pressure to the loader arms it applys an equal and opposite pressure back, that is when the loader bucket encounters a more ridged object then clean fresh air. So the slush while it may not look like much was causing enough back pressure to make the front end of the tractor lift. The lift is being caused by where the loader actually attaches to the tractor, on most of the tractors out there that would be above the center of gravity at the mid-point of the tractor.

The resulting angular pressure on the mounts lifts the front end, and you have a wheelie. :D

Not uncommon, depends a lot on the tractor/loader, surface and angle of the bucket.

+1 on this answer. I'd make a bet that when this happens and you stop the front goes back down. If there was pressure the front would stay up until you moved the stick.

I do. My FEL only goes into float when I want down pressure, and locks into position when I want it to float. I hate the float "feature". Factually, I'm not even sure what I am supposed to do to make it go into float, but I'm pretty sure that I have to hold the lever up to keep it there. OTOH, my tractor has 2600 hours on it, and the FEL control is pretty sloppy.

+another 1 on the answer and +1 on the bet. Completely normal.

Yup, same here. To explain it better, the tractor is simply 'overrunning' the loader. Next time it happens, try stopping and backing up. I'll bet the front end of the tractor just drops down. I usually don't float when driving ahead. Only when back blading with the bucket.
 
/ anyone else have this problem? #10  
+3, or are we on 4 now????

I agree with the others. Completely normal. Float isn't really made for going forward as you have found out. It is more geared toward backdragging.

in float mine sometime will do this - like pushing pushing snow - the front end will ride up and the FEL stick will pop out of float, seems like it has some type of override kickout? when it does this i just stop back up, put in float again and keep going. btw, i'm riding a JD 4720.

I love when Newton makes his way into TBN. :thumbsup:

My tractor is a Mahindra but I believe most joysticks operate the same. It's simply a matter of the float detent getting a little sloppy and allowing some of the fluid to start bypassing in the spool to the down position. When this happens on mine I replace the two balls & springs in the float detent and all is well again until they get some wear on them again. Holding the joystick up into the float position fully with your hand will stop the problem but that ties that hand up and is very inconvenient. When mine gets sloppy enough, I can put the stick into float and with the tractor parked and bucket flat on the ground and running it will slowly start picking the front wheels off the ground if I leave it there running long enough.

What the OP describes is normal, not a valve malfunction.
The FEL float function has it's uses, but for me pushing heavy stuff usually isn't one of them. As others have noted, it's great for backdragging. It's also very useful going forward if you want to skim a light layer of something off a hard surface, but once the bucket meets any resistance to forward motion it will start lifting the front end.

I agree with ya all that it's not a problem with the valve. My 933 Cat. does it, my TC40 New Holland does it, the next door neighbors J.D. does it and if I had a loader on my Kubota, it would do it. Can't be that all those valves are bad. Just have to learn when and when not to float when it contact with the ground.

Happy pushing and have a great day,

Glad you asked this, it was happening to me (a new tractor owner) and wasn't sure if there was something wrong. Thanks, now I know there is nothing wrong. :thumbsup::thumbsup:

I posted this in response to a similar issue that concerned a BX. The principal is the same tho.

That drawing is very 'telling'.:thumbsup:

Yup + 5 +6 or whatever
No hydrolics involved. The bucket is digging down and the tractor is trying to drive over the loader.

+18... my M-F 2310 will do the same thing. When that happens, I take it out of float and raise it just a bit.

Also helps to ensure that the FEL isn't tipped downward --even a bit-- such that it'll dig in on its own.
