We've tried these excellent ladders and they are so versatile. Depending on the slope, you can either work face-on, with the 3rd leg poked into the hedge, or sideways, with the ladder parallel to the hedge. They allow you to spend all the time necessary to do trimming and pruning jobs properly, without rushing because of the their adaptability, stability and comfort.
Ideal for orchard work, both for picking and pruning, where thanks to the single back leg, you can can get right into the crown of the tree. Unlike traditional orchard designs (pointed A-Frame), you can lean over the top, or rest picking baskets etc on top. They’re also considerably wider at the base than A-Frames, have the telescopic back leg (vital on slopes) and of course are welded not riveted, so are much, much stronger - and exceptionally light and easy to use.
