Not sure if this is the right forum, but I consider the Kubota & New Holland etc. type TLB units to be compact ones, correct? Anyway I need to plant some 3.5" - 4" caliper maple trees and need to rent a machine for this job. Can anyone help with what size of either of those I should look for, since I will be ordering over the phone as opposed to standing in the rental yard saying "I want that one". Those 2 are the most common brands of those rented around here (sometimes JD also), but I am not familiar with what names or numbers they go by like a Case 580K or JD 410 or a Cat D-4 etc. I don't want the smallest machines they have, but something in the mid range should work, and probably don't need the largest either. Thanks.
