rear lift springs

Postby Negreetfarmer » Wed Apr 08, 2015 11:20 pm

Has anyone ever replaced the springs on the back of their tractor if so what did you order mine are worn out and don't really put any pressure down on my rear plows allowing them to kind of ride on top of the soil.

What springs are you referring to? Does your plow have a depth control lever?
It is common sense to take a method and try it. If it fails, admit it frankly and try another. But above all, try something.

Photos of your tractor and plows set up.

At top of page, manuals, is quite a number of implement manuals. Free down load.

When the term "plows" was used, I'm thinking rear mounted cultivator.

Edit: Having spent years cultivating row crops and using plows to turn soil, once the implement(s) were set up correctly, they did not take down pressure to enter the soil.

Another thought. I have several 2 wheeled garden tractors with mold board plows. By changing the angle on the plow point I can either skid the plow across the lawn without lawn damage or tip the point down and plow the garden.

I'm guessing these are the springs that are being referred to.

Yes Mr. Don that is the springs I'm talking about my rear cultivators just kind of ride on top of the soil instead of going down like the front cultivators do. They are adjusted the same height as the fronts are.

Have you adjusted the nose angle of the sweeps/shovels/plows?

Yes I have adjusted the angle and tilted the nose of the sweep all the way down. I also got 2 ground clamps and put underneath the bottom of the lifting clevis so thesprings essentially were not doing anything and it plows great now. I just believe my springs were worn out.

Points pointed down as far as possible may be too far and just sliding on surface, a sweep is like a molboard plow, it pretty much pulls itself into the ground, with the springs just helping some.
If you are not part of the solution,
you are part of the problem!!!

As Bob pointed out above, you need to loosen the lower collar set screws, pull the collars up against the springs to compress them and then tighten down the set screws. This will increase downward spring tension on the tool bar when the hydraulics are lowered against the springs. You do not need any extra clamps on the rods.

If you are asking about simply having no springs or springs that have lost their springiness, John covered the answer.

If you are asking about running the collars up until the springs are totally compressed or removing the springs and running the collars fully up, not a good idea. You need the springs to allow some give when you are on an irregular surface, hit a rock or something else, or lower the cultivators when the shovels can't go immediately into the ground (like when stopped). With no springs, you will sooner or later bend something.

I did not mean to suggest that you should fully compress the springs when taking up the loose slack by raising the lower collars on the lift rods. As Jim points, out you need to leave some reserve spring to permit the shovels to raise up and pass over rocks, etc. However, if the top of the springs are not firmly in contact with the underside of the lift guides, the only downward pressure you will have on the shovels is the weight of the tool bar, the shanks, and shovels and, as John points out, the angle of the shovels. The tool bar depth adjustment is set by the collar on top of the lift guides. The depth adjustment on the rear tool bars should be adjusted to approximate the settings of the lift rods on the front tool bars.

those springs have nothing to do with enabling the cultivator sweeps to dig into the ground. The only purpose is to allow give if the cultivator hit something. I have never heard of the rear cultivators or for that matter the fronts as well not pulling themselves into the soil after the soil has been properly plowed or disked.
