Blade Clearance from Ground

[stuart]

I purchased a Frontier RB 1172 for my 4300 JD. With the 3 point hitch in highest position I have about 6 1/2 inches of clearance between the blade bottom and the ground.
I played with the adjustments to raise the blade as high as possible.
I have a quick hitch attachment on the tractor.
How's my clearance?? Is 6 1/2 inches high enough? Do I need to do something else to raise it higher. Any thoughts or suggestions appreciated.

I agree that seems a little low for maximum height. I would have trouble crossing little troughs or approaching hills.

Can you shorten the top link on your 3 point just a bit? Making it a bit shorter, should yield a lot of height out back without goofing up your blade angle too much.

Or you could just let all the air out of your front tires.

My 4010 doesn't raise the LX4 very high in the back when the top link is adjusted to get 1" higher cut in the rear. Only way to get it higher is to take up on the top link all the way. It'll go up high enough then for traversing uneven ground or for lowering onto shrubs to chop them up.

One thing that I found when my 4010/LX4 were delivered was they had put the LX4 lift pins in the wrong holes (think it was the higher holes). This made the top link longer than the bottom lift arms. So, by geometry, raising the 3ph drove the LX4 trail wheel into the ground. I moved the lift pins, and it works fine as noted above.

Hydraulic Top Link....shorten it when you are transporting, put it back "level" when your using it...

Yep that's the way to go if possible.

Thanks for your replies. I tried shortening the 3 Point lift arms and gained an inch or so. I do not have hydraulic top link (I wish I did of course). If I had understood the importance of hydraulics at the back of the tractor I would have had it installed when I bought it.
You are basically saying that by shortening the top link I would have the best chance of raising it higher. I will give it a shot.
Anybody have any idea what the proper clearance between ground and bottom of blade should be????

It does not sound correct...can you post a picture please? Do you use any other 3PH implements?

Kenny: It did not feel right to me. I can post pictures but it will be a week or two before I return to the farm. I will resurrect this thread at that time. Thanks

Does the 4300 have adjustable 3pt arms? On my 2320 the part actually does the lifting has 3 holes were it connects to the actual 3pt arms.. Mine came in the middle position and I moved it to the top hole and that gave me some additional lift. BUT you do loose some weight capacity

Bingo, I think you nailed it.:thumbsup: Good call.

There are two holes in the draft arms (Part # 26)
