using arbor ('tripod') ladder on uneven ground...

[johnny_canuck]

Greetings --

 

I have a long (150') and rather high (10-12'), and rather wide (8-10') hedge on one side of my property. Trimming it is not an easy job. Part of the problem is the ground. One one side of the hedge, the ground is level, and firm. Fine - straightforward. But...on the other side of the hedge, the ground either (i) slopes down towards the hedge, or (ii) is 12-18" higher than the ground that the hedge is rooted in. See attached.

 

I'm seriously considering the purchase of a good 'tripod' (arbor) ladder, with an adjustable extendable leg (specifically, a Hasegawa ladder -- local dealer). What I can't suss out is how to use said ladder for either scenario (i) or (ii). About the best I can come up with is to try to build up a block of some sort (say, cinder blocks) under the hedge, and then put the leg of the ladder on it - with the top of the cinder block being so many inches above the ground. 

 

Any other options spring to mind?

 

Cheers....
