Purchase of a Trackless Sidewalk
Plow/Mower
Recently I became aware of a used 1993 MT Trackless (brand name) sidewalk
plow that has a 12 foot front mounted mower attachment that is being
offered for sale by the City of Maplewood for $20,000.
In the 1997 budget, I have requested a $10,000, 12 foot wide, tow behind
mower for the Cass property and other park mowing. The sidewalk plowing
capabilities would be a welcome addition also since this would then become
our primary sidewalk plow with our present trackless as a second unit and
our Gehl skid steer loader as a back-up unit. This purchase would be funded
with park equipment reserve monies. I would suggest that the City Council
authorize the purchase of this MT Trackless using $10,000 from the street
equipment reserve and $10,000 from the park equipment reserve, since this
is a dual usage machine.
This machine has 1100 hours of use which is about 10 percent of the
machine's normal life span. The cost of this unit new is over $65,000, so I
feel this is an excellent value for our city.
Action Requested
The Council is asked to authorize the purchase of a used 1993 MT Trackless
plow/mower using $10,000 from street equipment reserve and $10,000 from
park equipment reserve.

]-he Trackless Snow Blower is a highly
efficient two stage, twin auger unit that has no
equal in removing snow from sidewalks.
It is available in two widths, 51 inch and 70
inch. Both will accept either a sidewalk chute
or a quick change truck loading chute. Many
municipalities utilize both chutes with their
snow blower. After clearing their sidewalks,
they change to the truck loading chute to load
windrowed snow from the street or from cul
de sacs. In both cases the maneuverability
and physical size of the MT and blower are
less apt to create traffic congestion than
larger snow blowers. An average loading time
for the MT and snow blower is 7 yards per
minute.
Overall heavy duty construction includes 3/8
inch thick sideplates, a double wall impeller
housing and a 15 inch diameter bearing
assembly for smooth accurate chute rotation.
High strength, Iow alloy steel augers with ice
picks and a heavy duty balanced impeller,
~asily handle the toughest snow conditions.
l'he snow blower is manufactured by
Trackless Vehicles to ensure that the quality
and service parts availability is equal to that of
the MT.
Positive and accurate steering of the blower in
confined areas and around obstructions is
due to the articulated steering of the MT. The
ability to move the blower sideways by simply
turning the steering wheel allows the operator
to safely approach any obstruction.

The Trackless wing type mower was designed to
drastically cut mowing time on those large areas ~
such as campuses and parks. Normal undulating
ground required flexibility in mowers to avoid
scalping. Trackless solved this problem with a
3 section front mounted mower comprised of a 72"
'3 spindle PTO driven centre section with a hinged
24" hydraulic driven wing on each side. Separate
'valves control each hydraulic motor and lift
-~ cylinder giving the operator the option of 72", 96"
'and 120" cutting width. The MT V has a built-in
hydraulic system to power the right wing and an
?ptional pump and valve to powe.r the left wing.
