Looks like the one in the avitar puts the hook ABOVE them normal attach point instead of behind. So, you may not have to add length, you will loose some functionality of your lift, your ground engaging attachments will loose a couple inches of depth.
There is just no way to add a quick attach of any sort to the factory lift arms and NOT alter some aspect of the lift. It is physically impossible. The only way to get quick attach hooks and not change any aspect of the hitch would be to cut the ends off the arms and place the hook so that it is in the same place the original eye was.
I agree but it makes more sense to Me the extending the lower arms & putting more stress on everything . even if it is just 2 or 3 inches. Looks like a great deal to Me. But of coarse you have to get off the tractor. which is needed anyway if You have to atach the PTO shaft .
As far as it effecting the Height of the impliment , thats a pretty simple fix as well IMO
Still beats the heck out of the way I have to do it . Bob
I,ll take 2 sets please & let ya,ll know how they work out.
