Let me throw my 2 cents worth in as someone who owns both a skidsteer (Bobcat) and a larger tractor with a FEL ( Kubota 5030 w/LA853 FEL).
First, do not expect anywhere near the bucket performance of a large tractor compared to a skidsteer. I would strongly advise that you rent or demo a Tractor with a FEL capable of lifting 2500lbs to max height and see how comfortable you feel. I have said it before on TBN and I will say it again, a FEL on a large Tractor (one capable of lifting 2500 lbs.) is next to useless, especially on a construction site with uneven ground, holes etc.
As I see it , part of the problem is that the tractor manufactuers all try to out do the other...just like whats been going on in this thread...JD can lift this much this high..Kubota can lift...... so much so that the buckets on the FEL's are so far out in front of the Tractor(to be able to brag about lift height) that with any kind of load in them they make the tractor so unstable and tippy to the point of being useless. Counter weight or not you would have to be a daredevil to try and safely move 2500lbs. on a Tractor w/ a FEL on any type of uneven ground. Futhermore, because the bucket is so far out front you have no idea where it is in relation to the task. I believe you will be very disatisfied with this set up on a constuction site especially coming from a skidsteer.
Ironically, the FEL's on the smaller units, like the
BX23 are useful, simply because they are smaller and are not so far out in front. I have used my neighbors
BX23 w/ FEL and it feels quite stable.
At most I use the bucket on my Kubota 5030 to move mulch, it is that useless. For any kind of real bucket work you cannot come close to the speed and stabilty of a skidsteer. Why not keep the skidsteer and buy a 45 hp tractor without the FEL or alot of bells and whistles.
