Fixing Problems With Your Tractor Lift Arms catdumptruck.com | Your tractor’s lift arms have been acting funny for a while now.
They used to move up and down on their own. The problem is that now they won’t respond to your control and come up and down completely on their own.
The pto and the lift arms have been working fine until they both stopped. This is causing you great frustration. Here are some possible causes and how to fix them. Hopefully you’ll find your problem and be able to get back to work sooner rather than later.
FEA Results For Tractor Lift Arms
The design of a tractor lift arm can be influenced by the FEA results. It was found that the arms are capable of carrying a load of up to 16kN. This load represents a normal operating load of a tractor in its class.
The fatigue analysis showed that the arms are susceptible to failure if the load is heavier than the designed lifting capacity. In order to design an arm with a safe lifting capacity, it should have a three-point hitch and be designed for a load of up to 1430 kg.
The power lift unit (PLU) lowers the drawbar I5 and raises the rear end of the frame 59. The lift arm sections IIZ are positioned so that the scoop engages the ground.
The scoop is usually held against pivoting, but when the load is lifted, the power lift unit valve V raises the tractor drawbar 55 and swings the drawbar arms 25 forward. In this way, the load can be lifted.
#Welding on Extensions is a Bad Idea
The first thing you need to know about welding on tractor lift arm extensions is that this type of repair is not a good idea.
You need to aim for 100 percent penetration. In many instances, you will see people running a 1/4-inch bead around the outside surface and failing to provide enough strength to match the original bar. Ultimately, you will need to V out the broken bar and ensure that the entire thickness of the extension is welded.

#Controlling The Lift by The Controller
If you need to adjust the height of your implements while working on your farm, controlling tractor lift arms with a controller is the perfect solution.
You can set the height based on the size of the implement and the bunds that you will be using. Then, the controller will turn the implements to the appropriate height for you. In addition, the controller will also allow you to reverse the lifting and lowering of the implements.
The hydraulic lift mechanism of a tractor consists of a pump and a valve with a spool (31). The operation of the valve causes pressurized oil to flow into and out of the cylinder.
The piston is connected to a Rocker arm or Rockshaft. The lifting arms are mounted on this shaft. By controlling the height of the implements, the operator can adjust the working depth and make adjustments without too much effort.
When the 3 point hitch does not drop, the problem is a mechanical failure. Usually, it is the result of a bad piston seal. If it’s the case, you’ll need to disassemble the lift arms and check the cylinder for rust.
It is possible to make small adjustments to the lift cylinder while in the middle of its travel. In most cases, you need to move the lever 1/4 inch further to achieve the desired lift range.
The controls on the controller can also adjust the height of an implement by releasing hydraulic oil into a reservoir. You can also set the height of the implement by pressing the lowering button.
The lever will then automatically lower the lift arm to the pre-set height. Once the implement has reached the desired height, the lowering control will move the implement inward and bring the hydraulic system into neutral. You can also use the draft or position controls to control the depth of the implement.
Another common mistake in lifting and lowering a tractor is the operator using the wrong hand. A mechanical joystick is the best choice. Its lever is designed for ergonomic control.
This lever also provides access to all buttons. It allows you to control the tractor lift arms with the highest level of ergonomics.
You can use the joystick to control the second function while occasionally diverting control from the third function. It’s not a bad idea to get an ergonomically designed joystick.
#Repairing a Junction Box
If you have to repair a tractor lift arm, you may not be familiar with the basics of mechanics. For example, if your lift arms have a broken piston seal, you will need to replace the three point arm pistons.
Luckily, you don’t need to hire an auto mechanic for this job. This easy repair will save you time and money. Simply follow these steps and you’ll be back in business in no time.
