|Here's my "new" Allis-Chalmers
716H garden tractor (aka Simplicity 7016), ID# 1690211 005353, built in 1978.
It has a hydrostatic transmission, electric implement lift, 48"
mower deck, and a 36" rear tiller. The engine is a single
cylinder 16HP Kohler model K341S, spec#71240A, s/n 9538767, carburetor
|3/4 view of the tractor. The
mower deck is ID# 1690272 9590.
|Photo of me on the tractor for
size comparison. Notice how deep the mower deck is. I hit some
deep grass and it handled it without a complaint. It doesn't
have the discharge guard, and I'm a bit worried about throwing
rocks with it. Will have to make up a guard soon.
|This photo show's the 36"
rear tiller. It's belt driven off of the same clutch as the mower
deck. The electric lift raises the tiller via a cable. The tractor
has enough weight and power that the tiller doesn't push it around
at all when tilling.
|Another view of the tiller. The
hydro level is clearly seen next to the steering wheel. It has
a "Z" gate to keep you from shooting straight into
reverse when your moving forward. Changing from the tiller back
to the mower deck takes under 10 minutes with one person.
|Rear shot of the tiller. It's
just a bit wider than the wheel base of the tractor, and takes
care of any tire tracks. The tiller is ID# 1690039 007872 and
uses belt #105340.
|Here's my first attempt at tilling
the garden. I had already done the garden with a small front
tine tiller. The tractor works better than I had hoped. Can't
wait to use it again next spring to prep the garden. Wish I had
the tractor 3 weeks ago before I tilled by hand!
|This photo shows how the hood
and rear seat/fender hinge up for maintenance. It makes getting
to the belts and such very easy.
|A photo of the hydro transmission
and PTO clutch pack. The hydro runs off a belt from the engine,
and inturn drives another belt that spins the differential. There
is a release pedal to move the tractor when it's turned off.
The hydrostatic tranny functions as a brake when the engine is
|Update 6/4/2001: Although the
tiller worked very well, it and the tractor vibrated an awful
lot while tilling. When I had a look, I noticed how far out of
alignmen the belt drive was. This picture was taken head on.
The pulleys really are that far out of alignment.
|Another thing I figured out was
that I hadn't been putting the lock pin, shown here, in the correct
hole. The white pulley assembly had been abused at one point
and wouldn't push onto it's support shaft correctly. A bit of
quick work with a Dremel and it slid right back on, and the bracket
lined up with the correct hole. This threw the pulleys out of
alignment, which I'll remedy soon.
|Update 6/7/2001: After some coaxing,
the drive pulley came off. I used emery cloth to clean up the
shaft, used a file to take out the nicks, and with some anti-seize,
the pulley went back on with a small brass hammer. It lines up
nicely now. The tiller does run a fair bit smoother too. In this
shot, you can see that guards are missing, and the spring tensioner
for the belt is all wrong. Someone removed some parts in the
|Update 1/2/2010: I located a used Deutz-Allis
snowblower, model 1691157, at Sandy Lake Implements in Pennsylvania and
had it shipped here to Oregon. With the help of folk at the Simpletractors
forum, I was able to piece together the info I needed to mount it to my
716H. I added a pair of generic tractor lights as well.
|The "correct" blower setup for my AC
has the drive running off of the front of the engine. I didn't have
the clutch parts for that and preferred to drive it off the PTO clutch
used to drive the mower deck, which uses a much longer belt and different
idler brackets. I built the stationary rear idler bracket, and the correct
front swing idler bracket came with the blower.
|The lift rod that came with the blower
was far too long, being designed for one of the 900-series tractors
which have a longer frame. I was able to make a new one out of bar stock.
I also had to make a new front lift arm to make things line up.
|A neighbor loaned me a set of 50 pound
wheel weights which bolted up nicely. I added a set of v-bar chains as
well because even with the weights, the tractor spun out easily on
packed snow or ice.
