Eagle Hitch 3pt phenomenon

After making special brackets to adapt my 3pt snowblower to my 830, Im discovering some unusual mechanics of the raising & lowering. I understand the arms of the eagle hitch are 3-4 inches shorter than most 3pt arms & the center link seems it's located higher as well. I've got the snowblower to rest on the ground ok but when I raise it there seems to be more pivoting motion than what I've seen & the arms have to be completely raised only to get the blower only about 5 inches off the ground. I've adjusted the center link, which helps, but something isn't right. Do I have to shorten the center link some to match the length of the arms or is the design of the 3pt positions the issue? This will be the first winter I've used a Case 830 on a snowblower...hope she has the power. lol. Anyhow, I hope to hear your replies.
 
you need to raise the attaching point on the snowblower for the top link,, did this on a blade and solved the issue, I raised it the same height as from the pto to the top attaching point you are using,,, 8"-10" I am thinking,,
 
Yes, same here. I built a blade for my 400 and had to make the upper mounting point quite high. So high that the top link slopes down quite a lot to attach to the top link anchor point when raised.
I just went and measured, and the top anchor point is about 29 inches above the main lift points. This is plenty, so you might be able to reduce this a couple inches. And the anchor is about vertical from the main lift point, maybe a few inches ahead, toward the tractor.
I could snap a few pics if you need. I can easily Email them, but have a hard time attaching them to this forum.

Could you post a few pictures? I have used a blade on my 400 with no issues. Are you using the casting that fits over the PTO for the top link?
 
he is running a snow blower with the PTO and is hooked into the Top mounting point,,, no way to use the PTO with the top link mount installed

I should have figured that out on my own. Thanks for bringing that to my attention Case Nutty 1660. Wouldn't it work better if the third point attachment was lower than you have it? If I remember right I tried using the upper top link bracket for my blade and had the same trouble as described.
 
Thank you for all your comments. I've disconnected the blower from the tractor & parked in shed so pics will come later. Even tho my 830 is a "dirty 'ol bird", I hate leaving tractors sit outside during rainy months & I anticipated leaving it sit outside the shop during the winter months plugged in & ready. I will study your comments & try to see if what you've suggested can help my problem. I hate to ask a stupid question so bear with me. Again, thank you for all you've stated.
 
Raising the implement center point makes good sense since the center arm on tractor slopes so far down that it almost interferes with the hydraulic levers in back. Thank you again.
 
Well, I went & added about an 8 inch extension to the center link on my blade & snowblower. Now the raising & lowering look good now with no pivot motion as I raise & implements can be raised plenty high now. The snowblower is quite heavy. It's an older Loftness 7 foot but I only plan to use it on heavy snowfalls & blowing snowbank windrows from my back blade. I am really concerned about the center link on tractor....it's a casting & I have heard of one breaking but then again, what were they doing to crack the housing? Thank you again for all your input.
 


I don't know if it would work for you, but I welded up a top link attachment that bolts in the same place as the factory that goes over the PTO, but the hitch point is above the PTO so I can use it. Just used 4" heavy angle. Works good on my 811B.

My 830 has a homemade PTO shield made of 1/2 in. steel with the third point bracket welded to the top. Works great.
