In my quest to acquire useful implements to speed up work and to do a better job of it, I've been doing a ton of research into land planes. I got a quote from ABI for their 7' land plane for about $2300 including shipping. The 7' Frontier land plane is like $3200 (of course more $$) but it weighs over 900 pounds and the ABI plane is 765 pounds. The blades are welded on the Frontier as I recall and the ABI blades aren't and I think adjustable (maybe - I've looked at so many land planes.)
My Frontier implements are all top shelf, they are expensive but built like a tank (I have the heavier versions of the Frontier implements.) There's not a whole lot of feedback on ABI but the price is attractive (and includes scarifiers.) I had a Land Pride rotary mower, box blade and rake with my old Kubota and they were okay but a definite step below my Frontier stuff.
I know weight is important for ground contact implements and a very general indicator of build quality but what difference would 200 pounds make in a land plane. I'm real leery about ABI just because they aren't one of the major players in general purpose implements (and I do not believe they make the land plane themselves - it's sourced from a company I've never heard of.)
Just looking for a little advice here before spending more $$$.
