It won't be hard to get the backpacker back up, it certainly is not what I would call a mark against the machine, it simply collided with an immovable object.
I'm gessing the shock knocked a spring in the clutch out of action, resulting in the clutch being stuck, and the wobble that is causing it not to peak any more.
From what I have worked out so far, getting parts will not be hard, or expensive for that clutch, so I predict it will have pleanty more life to come for fute Jobs.
I'm no longer planning to swap the motor out, It looks like I may have sourced another backpacker with a very dead motor, which I will talk into accepting the honda, that way I will have one for High rev's, and one for High torque, like I have on this Job.
The Honda is great all round, and in no way struggles to deal with the thick brush, however for the general paddock scrub, the backpacker is easier to move fast with, and for the wide area spaces, it save alot of time, which also saves the honda for the tougher stuff, giving them both a few less hours in the day, and extending their lifespan.
