These might fit other models I took them off of my L3901 they have less than 25 hours on them. These are much nicer than the turn buckle setup they come with. PM me if you're interested.
They'll fit an L3301, and any of the older L series (L3200, L3800, L2600, etc), MX series (they'll be a little light for an MX, but the dimensions are the same). That's a great price.
I wasn't happy with the LA525 loader capacity on the L3901 tractor so I traded it back into the dealer for a new MX5800 with the LA1065 loader it's a much stronger machine has like twice the lifting capacity. So I figured I'd put the turn buckle stabilizers back on the L3901 prior to trading it back in these sliding stabilizers are in like new condition.
