FEL Downpressure on L3010

[nathanelmo]

Got my L3010 HST on Sat. and allready spread about 80 yds. of top soil w\fel and box scrapper. Machine is great! Question about down pressure on fel. Is it supposed to lift tractor front end off the ground w\hst trans? Mine does not or is very slow even with clutch in to eliminate hydro drag. (never used a hydro before) Any replys would be appreciated.

Press the bucket against the ground, then curl it to lift the front end.

We have a 3010HST with a Bush Hog 2246QT FEL and it pops the front wheels right off the ground. The manual actually recommends not doing it very often as it puts a high load on the hydraulic seals.

it won't if the bucket is in the horizontial position. put it in the full dump pos. and then lower it and it will raise it with no problem.

I've tried putting bucket in full dump then apply down pressure. It raises very very slow even at higher RPM. It will raise by curling bucket. I know a bush hog loader will lift it - larger dia. pistons more force generated. I'll run it for a while and see what happens. Only 11 hrs on it. Any other replys or comments would be appreciated. Thanks

First off, don't push in the clutch, this just weakens the Hydro pump performance. Second, you may want to check to see if the loader cylinders are already retracted to their maximum when the bucket is flush on the ground. You can tell this by where the paint line ends on the cylinder rod.

Lastly keep the bucket flat on the ground and then roll it forward. This will almost always raise the front wheels off the ground. If this doesn't work, then you need to get a gauge and check the PSI of the tractor/Loader.

Since it is not an OEM loader, it just may need an adjustment to the loader pressure relief valve.

Good Luck.

How many RPMs are you turning? You have more power with more RPMs.

with clutch in or out it wont raise w\ boom clys. long before I'm at the end of my travel, but bucket curl will raise it and boom clys. will hold. It is a kub 482 loader; I was just comparing to a BH loader because I'm familiar w\ its operation. This is my 3rd. kub w\ fel and over 3000 hrs. of operating time but my 1st HST. My other machines could lift w\ boom cyls. Kubota probably has a reason for regulating down pressure since it's not needed as much as lift force. Hydraulics aren't laboring so it leads me to believe there's a flo control in the valve body thus saving cyls unnecessary work. I'll check w\KUB and post.
thanks

The HST is acting like a brake on the rear wheels. If you put the range selector into neutral you will see that the front end comes right up. With the range in gear the wheels can't turn and the loader hydraulics are fighting this.

I usually just press forward on the HST pedal slightly while trying to lift the front end and then there is no problem.

Not true on mine. Whethter in gear (HST) or neutral the loader lifts the front end right off the ground. In fact this is the best way I've determined to go from 4WD to 2WD but that's an entirely different subject..

 

[frank_f15]

i agree! when back dragging with fel if i put to much down pressure , the fel will raise the front off the ground while i am going backwards, losing the drive of the front wheels.something don't seem right? he should be able to lift that with no problem.

Emailed Kub yesterday w\concerns on fel. A tech rep called by afternoon. He said because of the reduced fluid volume on the piston side there is normally less down force - enough to hold when bucket is curled and enough to lift slowly but not enough to pop the front end up quickly w\boom. This is due to the loaders geometry which requires ample counter weight in the rear. I did not load the tires and I'm only running a 375lb box scraper in the rear. My backhoe is going on next week; that should be sufficient. Lifting force is all there so I'm not concerned. Bucket curl will raise front end when necessary. I'll post after backhoe is on.

Jim -- Which backhoe did you opt for? I put a Woods 7500 on my L3010 a month ago and absolutely love it!

Great Bend 752 -- same as bush hog and probably some others. Great price, w\pto pump and sub-frame, from a dealer in plainfield CT (westview tractors). And it's Kub. orange.

I have a 4610 and it will cleanly lift the front end, no curling of the bucket required. I had a 2900 previously and it wouldn't lift the front end for love or money but I could however curl the bucket and the front end would come up very easily then.

 

[rozett]

The FEL down pressure will easily lift the front end of my Cub Cadet 7360..... makes it very easy to change the flat tire. /w3tcompact/icons/frown.gif

Hmm... I wonder if I can use jackstands and the TPH to raise the rear end? But that wouldn't help remove the (loaded) tire once its undone. /w3tcompact/icons/hmm.gif
