Just replied to your other post about grapples. Looking at the picture, it's clear that this grapple is much lighter duty than the Markham. For instance, there is no steel protective shielding encasing the hydraulic cylinder on top like the Markham and most other brands have. The construction seems much lighter. I doubt if it's any cheaper in cost than the Markham. Quit shopping! Buy a Markham. Get a 48" light duty if your tractor is less than 45hp or have them build you a 48" standard duty if you have a bigger tractor like I do (Kubota M 6800). Ask Islandtractor, he's the grapple guru.
