Sorry I wasn’t implying you did.

Well I don’t own this model but if I did and this was the case every time I lowered a full bucket I’d be pissed. Imo if it can lift it it then should be able to safely lower it without having to add flow restriction valves. I was always under the impression team orange had team green when it came to hydraulics. Guess not on every model.
Team orange hs been hydraulics challenged for decades. Just look at somd of the crazy plumbing they have put on tractors. They still have backhoes that require stopping the engine and looping hoses together.

The LA525 loader can be safely lowered when maxed out but you wont do it rolling along and I cant imagine wanting to.

You need to stop the tractor and "very carefully" coax the joystick out of neutral. Too fast and you get a rapid drop that will bounce you around when ypu catch it. Lighter loads behave fine.

@TheOldHokie - since it is cable to the valve is there some (kinematic) device that is available to slow the valve travel down in relation to the handle movement?

My thought was the cable controller simply provides better leverage.

I really dont see any use for flow restrictors here. They have their place but not in this application. Generally speaking you are trying to speed up loader cylinders not slow them down.

What needs to be done is increase the feathering control of the valve. If there is any possibility, unscrew the knob, and then replace the knob with a connecting nut of the kind used for connecting two threaded rods together. After that, find a length of allthread rod with the same thread pitch as the knob and connecting nut. Experiment with how long the hydraulic control lever should be to effectively feather the control valve to prevent such a sudden drop of the loader. Having the hydraulic control lever way too short isn't any help with modulating the hydraulic fluid flow rate through it by hand, as it should be. Yeah, finding metric allthread rod might be a problem, but try to find some quick and easy way of extending the length of the hydraulic control unit lever so you have far more control over its "throw".

I know that this is an old thread, but my 2 cents....

On the controls, it's easy on, easy off. Slow control movement is key, until you know the machine. Experience makes the operator match the machine. Usually, there is nothing wrong with the machine. The operator is the problem.

I've known operators that could tap you lightly on the shoulder with a large backhoe. BUT they had years' experience on the very same TLB.

Operate it, know it.

I'm always amazed how many folks complain that the loader stops too fast or jerks too much.

Some people with ZERO experience, jump on their new tractor and say it's jerking the machine when they use the loader or backhoe.

Rule # 1: Learn the machine. Slow movements on the controls. Start slow and learn how your control movement affects the implement. Loader, etc. Quality. This, usually, takes a long time. Unless you are a fast learner.

Rule # 2: This, is an orchestra. The bits and pieces of the "band" (you and the tractor) work together to form quick yet smooth fluid movements. It's like music when you see a skilled operator use a machine that he or she has operated for years. Usually, it's not the machine jerking. It's you. You and your new Kubota are to be One fluid machine. Quality. This comes after Rule #1. But you will know it. You and your Kubota will BE it.

Rule # 3: Nobody Cares. Take your tractor and get hours and days and years on it. ONLY try to impress yourself. In the meantime, everyone will be impressed with your skill. And YOU will get a lot of work done. Quality.


If you have the time and see a road crew working. Stop and watch the backhoe operator. He or she has probably done it for years. It's like a master at work.

Like music. Time in the saddle.

I have a 2017 Kubota L2501 with an LA525 loader, and I frequently lift heavy loads. The loader drop and bucket tilt/dump forward functions are extremely touchy — and unsafe moving around 10 bales of hay. And also other heavy objects controls are just way too sensitive. Even using two hands on the joystick, it’s very difficult to control smoothly under load.


If anyone has successfully installed one-way flow restrictors, adjustable flow control valves, or any other solution that helped tame the loader down and bucket dump functions, could you please post pictures and details of your setup?

I’d especially appreciate:
  • Where you installed the restrictors/valves
  • What parts or fittings you used
  • Whether you used fixed or adjustable restrictors
  • Any before-and-after impressions
I’m hoping to slow only the dangerous directions (drop:tilt) while keeping normal raise and curl-back speeds.
Thanks in advance for any help or photos of your installation.

Many yrs ago I installed an adjustable flow control valve on boom circuit on a M4900 that had a Kubota FEL. Feathering cable controlled FEL spool valve while handling 1000 # rd bales with a 49 HP with sufficient rear counterbalance weight didn't suit this Old Man that had been operating tractors & FEL's for over 50 years. I install check valve due to boom lowering way too quickly while handling 4X5.5 rd bales. Sorry I don't have any photos due to in 2012 trading M4900 for a larger M7040 with FEL that has not required altering boom lowering speed handling same size bales. IIRC I installed flow control valve on rod end of boom cylinder hyd circuit & problem of lowering 1000# rd bales was immediately solved!!!!!!!!!
