130 Hydraulics

[BohemianJon]

I just purchased a 3-point Brush Hog Type Rotary Cutter Mower that weighs about 500 lbs for use with my 130...but the hydraulics does not seem to have enough power lift the mower. The hydraulic fluid is full and the hydraulics works correctly without the load. Am I expecting more than I should or is there something I need to do with the hydraulic system?

Does your 130 Have the "helper spring" along the left side of the tractor that compresses when you lower and then "helps" lift when you raise it?

[BohemianJon]

No it does not have such a spring...just a straight bar going back to the rear lift.

Is it a three point conversion? If so it may have the standard rockshaft with no provision for a helper spring.

Take a look at the blue ribbon service manual for the Touch Control in the PDF manual section here. It gives you instructions on how to do some diagnostics to the system.

I do not know which ones had the helper spring and which ones did not however I suspect if you had the helper spring it could lift quite a bit more. I have seen them both ways and I do not know why some have the helper spring and some do not ?

If it came with the standard rear rockshaft it will not have a helper spring. If it came with a fast hitch it will have a helper spring. If it has a FH and is missing the spring somebody took it off, or added a FH to a tractor and did not install the helper spring.

Thanks for your comments...My 130 does not have the Helper-Spring or the Fast-Hitch...just a straight plain bar going back to the
rear lift. and the 3 point conversion set-up. There are no leaks that I can find and I think I've worked out any air in the lines.
My questions are...with these hydraulics should my 130 be able to lift the 500 lb, brush cutter? If it is designed to make this lift,
what do I need to do...clean a filter or screen, rehab the pump...or is the 500 lbs just too heavy for this set-up to lift?

If you have a 3-point implement why not get a tractor with a factory 3-point that has draft control and floats and has other modern features such as a MF 135? Was the 140 tractor ever intended/designed to have a 3-point hitch?

Read the touch control manual I mentioned earlier.

If it was a fast hitch cutter, 4' wide, on a fast hitch the answer should be yes it would pick it up if the hyd. system is working right. In your case, troubleshoot the touch control as I said.

I'm not a fan of the three point conversions.

If everything is working perfectly, your rear rockshaft should be able to lift something in the 8-900 pound range. However, that is AT THE ROCKSHAFT. Depending on the geometry of your 3-point, the available lifting force could be considerably less. I'm not a big fan of three point conversions either, especially on a Cub or the Super A/100/130/140 tractors. More often than not they are some half-baked system built by someone that doesn't understand the geometry of a proper three point system.

[BohemianJon]

HEY JIM BECKER...I was hoping you'd give me some guidance with my problem...your "hint" regarding the geometry was right on! I had the 3-point lift arms from tractor to the brush cutter hooked up wrong end for end and was using the wrong holes to hook up lifters from the arms to the rockshaft. After figuring out the correct geometry and changing the hook-ups several times everything works as it should. I agree that the 3-point conversion isn't the best...but its all I got to work with as my 130 doesn't have the fast hitch or the helper spring.
What are your thoughts about my removing and cleaning the screen in the hydraulic reservoir? Any other suggestions/recommendations?
THANK YOU VERY MUCH FOR YOUR EXPERT HELP! I sincerely appreciate it and all your great service on this form. John BohemianJon Florian

Unless you have personally changed the hydraulic fluid, you can guess that it has probably never been done. As such, changing the oil and cleaning the screen is probably well overdue but not an immediate rush item. I'd pick a day when you have some time to deal with a damaged screen (repair or replace) if that is what you find. Just follow the steps in the Owner's Manual and be sure to do it with both lift arms in the rear position.
