This two speed pulley can increase the effective operation of various attachments. It is designed to provide a direct drive which reduces ground speed but not PTO speed.  When engaged, speeds will be reduced to one third. THIS UNIT DOES NOT ALTER THE ATTACHMENT SPEED.  The operator can change the tractor ground speeds without leaving the seat. This is done by the shift lever on the right side of the tractor.

This two speed pulley is particularly useful with the front mounted Snow Blower and Snow Plow dozer blade. It is also useful with the rear mounted rotary tiller and other tillage tools.

NOTE: This two speed pulley can also be installed on the 9 Hp. B-10 and B-1 riding tractors. However, it is necessary to cut 1" off of the pulley shaft. This can be conveniently done with a suitable instrument (saw) if the seat and transmission pulley is removed. Remove all burrs and metal shaving prior to installing this two speed pulley.

SPEED RANGES

STANDARD SPEEDS (OR) HIGH RANGE  LOW RANGE 
SPEEDS
First 1.6 MPH .5 MPH
Second 3.7  1.3
Third 6.1 2.2
Reverse 3.1 1.1

OPERATION:

Engagement of the reduced speeds is done by the operator pushing the knob to the left. Push to the right for disengaging.

IMPORTANT: It is important the tractor transmission is stopped for changing ranges with the low speed pulley. /Make sure the idler pulley is completely disengaged before the brake is applied. (This adjustment will be found in the tractor owners and operators manual.) This will eliminate the clashing of gears and prolong their life.

LUBRICATION:

Lubrication is applied at the factory. Prior to installation, remove set collar and pulley from gear assembly to determine if lubrication has been applied. After 100 hours of operation, remove capscrew from cover, insert the grease fitting which is shipped loose, and apply several shots of multi -purpose lithium- based type grease. Remove fitting and reinstall capscrew. IMPORTANT! DO NOT LEAVE GREASE FITTING IN THE COVER ESPECIALLY WHEN USING TIRE CHAINS. SUBSEQUENT DAMAGE CAN RESULT. Apply a little grease on shift pivots before slipping them over shift ring.

PACKING

The two speed pulley is shipped in one carton. The grease (zerk) fitting is shipped loose in this package. All necessary hardware is included.
