The above is not in stock either so I'm stuck with 54" grapples (LS or Braber) which are local.
The Mahindra dealer tells me they have a 3rd member electronic switch that Mahindra uses to divert the bucket functions to the grapple. You push the button and the hydraulics are shifted to the grapple and the same stick works the grapple as the bucket. $800 to install.
So, I'll be into the LS 54" grapple and 3rd member at around $3400 plus taxes but would be able to get busy and not have to wait 4+ months for a grapple and then until spring for the thaw to allow me access to a lot of the area I need to work in (even with 4wd and chains it's just too rough a terrain to get into when there are a few feet of snow over ice to contend with

).
