Snow Blower Hitch for 7000 Series Simplicity Tractor
Simplicity designed the 7000 (AC 700)
series tractor snow blowers/throwers to be powered by a front
PTO (Power Take Off) that bolts to the front of the engine. A belt goes
around that PTO, under the front axle, through a 2 pulley hitch, and then
around the blower pulley. This design required expensive machinery and
The Simplicity 7100
(AC 900) series tractor snow blowers/throwers are powered by the existing center
PTO, that is normally used to power the mower deck. After the mower deck
is removed, the idler pulley is repositioned to a second hole in another ear,
and a long (147") belt goes around the PTO, under the front axle,
through a 1 pulley hitch, and then around the blower pulley.
I decided to install a
snow thrower on my 7012H, but I didn't want to install a front PTO. To use
the center PTO I had to buy the long belt, and modify the idler pulley arm
by adding an extra ear with a second hole.
It occurred to me that
my mower deck belt is 74" long, almost exactly half the length of the
snow thrower belt needed. I knew that I'd never had a problem with my
mower deck belt twisting or coming off the pulleys. So, I decided to
retain the angle of the mower deck belt by fabricating a hitch with a
mounting pad that places an arbor at the exact location of the mower deck
pulley and use my mower deck belt to drive the arbor. To drive the snow
blower, I use my spare mower deck belt from the lower arbor pulley.

side view of the completed hybrid hitch.
The hitch was
fabricated entirely fron scrap metal. The only new parts purchased were
the 4 attaching pins.
Figure 2 is a
view from the back showing the 2 pulley arbor attached.
The arbor was
constructed from housings, bearings, and a shaft that were salvaged when I
rebuilt my mower deck. The blade end of the mower deck arbor shaft has the
same spline as the pulley end, so I replaced the blade with another arbor

the hitch lifted and the 4 attaching pins inserted.
Notice how I moved
the blower mounting ears in 3/4" on each side. This was necessary
because I am using a Kubota snow thrower. For mounting a Simplicity
blower, you would just extend the hitch side bars straight out.
