Very nice looking machine.
I have a 28' Built-Rite, with a belt. When the hand crank jack is mounted on the upper mount, an auxiliary mount above the axle mount, and the jack extended the conveyor axle moves towards the hitch. The hitch end becomes very light as the balance point shifts. A couple times it tipped end for end. I had a big pile of splits, and I increased the conveyor height. As the last of the splits moved up the belt, toppling it, and came to rest lightly on the high pile. Once it tipped coming to rest hard on the ground, bending the top drum shaft slightly. Replacement was a not too bad, and Built-Rite sent the shaft right out in the mail.
I'm bringing this up because I noticed on the Bio Mass, the hydraulic hoses mount on the bottom of the top drum motor, and appear to be the point of first contact if it tipped end for end. The photos do not show the wheels, tires and tripod set-up. With mine, the maximum height can only be achieved if it is hooked to something to keep it from tipping.
I have a question for you.
Is it quiet to run?
Some have said their conveyors are noisy.
Perhaps the chain conveyors are more so than the belted ones.
Mine however, has a squeal to it, which I think is the idler rollers that support the return section of the belt. They are unserviceable hard rubber wheels with no apparent bushings or bearings. Lubing them is a temporary solution. So far I have not found a suitable replacement, but I'm still looking.
