I used the search function but couldn't find my answer. When I lower the rear blade on my Kubota BX1500 all the way it seems to slightly raise the rear of the tractor; is that normal? Should I adjust the hitch so that the blade won't lower as far or is it normal for the tractor to seem to raise like that? Also, when I angle the blade and lower it to plow, it no longer sits level, one side is slightly raised so I cannot scrape the snow as low on that side of the blade; is that a normal occurence or do I need to adjust the hitch though it seems level when the blade is straight. Any help is greatly appreciate.

AKFord,
Your 3PL applying a downward pressure on the blade is not a bad thing and can, as you say be adjusted out. You should also be able to adjust it with your 3PL hydraulics. The angle thing is a little different. Not knowing what type of blade you have makes it difficult but I guess you have one that pivots at a point closer to the tractor than the center of the blade. Mine does both I can angle the blade by loosening the mother of all wing-nut's or I can angle it by relocating a pin and bar. You should be able to adjust this same angle with the tilt adjustment on your 3PL.
Post some pic's of your blade?

I doubt if it's raising the tractor. I suspect what you're feeling is the weight being taken off the back of the tractor. You may not notice, but I'll wager when you lift the blade, the rear of the tractor lowers a bit (tires compressing a little). And, of course, when you lower the blade, the tractor seems to rise...well, it is..but not higher then if you had no implement on the back.
When I pivot my blade, I have to adjust the lower (adjustable) link. The blade may appear level when it's perpendicular to the tractor, but it's probably not. When you pivot the blade, the end travels in an arc...in my case, if I pivot so the right end is closer to the tractor then the left end, I had to lengthen the adjustable link. I did this yesterday, so it's fresh in my mind.

Here's how it works for me with two different blades. Make the frame of the blade parallel with the ground with the blade in the "down" positiion. I make the adjustments with the toplink. Since the post of the blade is perpendicular to the ground, the blade will be at the same angle at any point of its rotation................chim

Adjust the 'top link' so the blade is level fore and aft, and then it should angle in both directions and remain level to the ground.

I think Roy is right on too.
AKFord, you could confirm this next time you have the implement off. Lower the 3PH, walk to the back of the tractor, and the see if you can lift the hitch arms. You will find you can...so the 3PH could not be doing anything to lift the tractor on its own, since it is essentially in "float" mode, as far as upward movement goes.
There are exceptions to every rule, but generally speaking cuts and subcuts do not offer down pressure on their 3 point hitches...

Thanks to everyone for their input! I think you guys are probably right and it sounds as though when I swing the blade (I have a 60" Rankin) to angle it then one end furthest from the tractor is going to be slightly raised due to the pivot point.
I will look at the center link but on my tractor I don't think it will help me level the tractor at all; according to the manual only the lower link can do that.
I do feel the tractor slightly lower when I raise the blade so I guess the opposite would happen when that weight is taken off the tractor. Thanks again to everyone for their help.

When the blade is straight, the 3PH leveling crank and blade adjustment are all that affect it. When you pivot the blade, then the tractor's fore-aft leveling affect it too. Hopefully the top link and any built-in adjustment can compensate for that. If not, maybe tire pressure can halp a little.

I just played with my back blade a few hours ago. I had the same angling problem pushing snow this spring. What I found is that I have to put my bx2200 on level concrete, rotate the blade 90 degrees so it is sticking straight out behind the tractor. Then I adjust the top link until the blade is level with the floor. Now I turn it to the straight plow position and adjust the lower link until the the blade is again level. I can spin my blade 360 degrees 1/4 inch off the floor with no drag. I only get about 6 inches of lift adjusted like this, though. By the way, my blade is the 60" Land Pride from TSC - nothing fancy.
