SETTING UP INSTRUCTIONS -- Continued
Setting-Up and Operating Instructions should be studied very closely before beginning to
assemble your Snowplow. A number at the beginning of a paragraph in the following instructions
refers to an arrow in the adjoining figure except when otherwise stated. When R.H. (Right
Hand) and L.H. (Left Hand) are used, it should be understood to mean from a position behind
and facing the Snowplow (or direction of travel).
Each Snowplow is given a thorough inspection before shipment, however, it is very important that it be again thoroughly checked at the time of receipt, to ascertain if any damage
has occurred in transit. A standard Snowplow shipment consists of the following package:
One Bundle Number 575x169 Rotary Snowplow
OPTIONAL EQUIPMENT
One Bundle Number 575x170 Slow Speed Pulley for any David Bradley Garden Tractor
equipped with Speed Changer.
One Bundle Number 575x171 Slow Speed Pulleys for Super Power and other David
Bradley Garden Tractors not equipped with Speed Changer.
INSTRUCTIONS FOR ASSEMBLING SNOWPLOW
Install slow speed pulley, (Bundle Number 575x170 or 575x171), per instructions furnished with pulley.
Remove the unit from the carton. Cut wires on scoop and remove the chainguard and mounting frame.
1. See inset B. Remove the two runners from the back side of the mounting frame and attach
them to the scoop with the clips at the rear of the scraping edge. The adjusting strap of
the runner attaches to the outer face of the runner support.
2. Attach the mounting frame to the scoop with four bolts as shown.
3. Refer to inset D. Install the roller chain on the sprockets as shown, and adjust until it
feels snug when depressed at the middle with the thumb. Lock this adjustment by tightening
the bolt through the two idler arms.
4. Attach the chain guard to scoop and bracket on drive shaft tube.
5. Attach the deflector to the discharge spout. To do this it is necessary to remove the guide
clips from the deflector so that it can be mounted with the spout extending up into the
deflector. After the deflector is in place, replace the guide clips so that they engage the
flange of the spout. Be sure that all clips are free on the flange of the spout so that it
will be easy to rotate the deflector.
6. Refer to inset C. Drive locator pin into handle spacer of tractor from the underside
until flush with underside of handle spacer. Mount control handle for snowplow on tractor
handle spacer and locating pin. Slip control handle retainer in from the right and bend
the tabs down to hold it in place.

control rod.
