I purchased a SH121 Walking Tractor from China Depot, in July, configured as
a rototiller. See a picture and specs at
http://www.chinadepot.com/sh121.html

The engine is an AMEC, made by the Changzhou Machinery Company. It is one
massively built piece of machinery... weighs about 1,040 pounds. The engine
is a single cylinder, 12 HP, electric start, heavy design with a large
flywheel. The HP rating is for 12 hour operation.... the 1 hour rating
is13.2 HP.The engine weighs 150 kg. It starts easily, and while there is a
small puff of dark smoke on the first 2 or 3 firings, it cleans up
immediately. Being relatively new and lightly loaded, I cannot comment on
overall durability. However, what I can see of it so far, I am impressed
with it as being a quality engine. Casting quality appears excellent.

I have re-configured it as a "Iron Horse" to haul sawn lumber and small logs
from my woodlot, as a key piece of machinery in a sustainable forestry
management operation. In Low 1st gear, which is used in lauling out wood
over rough ground, the engine will tow a trailer loaded with about 1200
pounds of wood, with the throttle set at the lowest position that permits
smooth operation... about 300 RPM. The engine is thus relatively oversized
for this specific application, and if I do encounter problems, they will
likely be due to underloading.... carbon buildup, etc.

The engine is of an elemental design, and servicing should be quite
intuitive..... it looks like it would be very easy to "figure out what the
problem was, and how to fix it."

In summary, at this stage, I have no concerns about engine quality. Note
that China is a big place, with many engine manufacturers. I am sure that
there are some bad Chinese engines, but from what I can see so far, this is
not one of them.

Hope this is helpful.

Kindest regards,

Kevin Chisholm
