Grading with a Jinma 284…..

well you have only weight to give you downforce for ground contact .what I did was to add two  50 lbs. suitcase counterweights off the front of a old massy 250 that my neighbor added a loader to so the weights were no longer needed. attach them as best you can and see how that goes.just do not exceed total weight on  your hydraulics.You might need to add more metal in the structure of the blade frame since you will be pulling more load (dirt) with the extra weight added.I believe that guys have talked about boxing in areas of the three point pins to make them tougher.good luck

I use a 4' blade to grade with, but only after I have used a box blade with the rippers set at the highest setting, to loosen the soil.  One suggestion:  If the blade is floating, you may not have it set to dig-remember, you don't have downforce, but you can set the height of the blade.  If it is set (curved into the dirt at the base enough to dig when it hits the high spots) right, it should pick up the dirt in the high spots.

This works well for me, and when I get the area levelled fairly good, I turn the blade around, put a little weight accross the 3 point frame, and drag the area with the blade just floating-it won't dig in, but will help to level and rough spots.  Bob

As the others have said, the TPH does not supply down force.  A hydraulic to link is dandy for changing the attack angle of the blade, but it really won't overcome the floating lift arms.  I just add weight to mine and set the angle to take a hefty bite when I need to cut the tops off hills and such.  Using the scarifiers first makes it go easier, too.
