I really don't know for sure.
Perhaps it may have been better to have this link on this 1100 BH & it may not have been required on the smaller BH offered.
Keep in mind when we first bought this tractor from the selling dealer it was in May of 2016. Dealer's name, Allen Farm & Lawn Equipment, no longer in business in Ocala, FL.
At this time the dealer offered two different size BH, but only one bucket size (9inch) for the lesser BH.
Even here, I never saw the other BH, but the dealer suggested it was the same size as a BH attached to a smaller tractor but w/ the same 3 cylinder
motor as was in the XG3025.
The dealer said this XG3025 had a bigger hydro pump & the 1100 BH was an upgrade & the larger bucket could be used as well.
At no time did we see any of this in a catalog, just conversation w/ the dealer.
IF YOU are using the 1100 BH on your XG3025, I suggest you consider this link. Perhaps another 50 USD.
To us, it just makes good sense. The recall dealer, Trenton Farm Equipment in Trenton, FL saw it was missing & rather surprised it had not been attached. We had the link in a box & at that time thought it was to be used w/ the other attachments, which we bought in our package deal.
But our XG3025H did not have the link attached when delivered. Link & a few other items were in a box & so they sat for all this time.
A larger frame tractor may not require this link advantage, if using the same back hoe.
To date there may be no other option for the XG3025(H) of back hoe size.
We have done a lot of stump removal w/ our rig. We have some near unbelievable pix of these stump extractions. This tractor combination Back Hoe 1100 is great for us.
