WHEEL GEAR AND PAWL SERVICE
IMPORTANT: Do not remove both wheels at the same 
time to avoid mixing of parts. (The R.H. and L.H. ratchet 
gears are not interchangeable.) 
Make notes on the 
position of washers and snap rings during disassembly.
•  Remove one wheel from the sweeper.
•  Remove the retaining rings and washers which hold 
the ratchet gear onto the brush shaft.
•  Remove the gear by sliding it off the brush shaft. 
(Look for the drive pin, which may fall out of the brush 
shaft when the ratchet gear is removed.) See fi gure 
26.
•  To reassemble, insert the drive pin through the hole 
near the end of the brush shaft. Make sure the pin 
slides back and forth easily in the shaft.
•  Lightly grease the shaft and fi ll the ratchet gear with 
grease. Assemble the ratchet gear back onto the 
shaft.
•  Lightly grease the axle and the wheel's gear teeth 
and then reassemble the wheel.  The brushes should 
rotate 
only during forward rotation of the wheel. If 
the brushes are driven (rotated) by both forward and 
reverse rotation of the wheel, the drive pin is jamming 
in the ratchet gear. Disassemble to clean and lubricate 
the drive pin and the ratchet gear.
BRUSH REPLACEMENT
NOTE:  Brush replacement should be done one brush    
 
at a time.
•  Remove the hopper bag from the sweeper.
•  Loosen the hex bolts and lock nuts on two single 
brush retainers which clamp one brush to the double 
brush retainers. 
Do Not loosen or remove the bolts 
which fasten the double brush retainers to the brush 
shaft. See fi gure 25.
•  Slide the brush out of the retainers, noting on which 
side of the brush the bristles overlap. See fi gure 25.
•  Install new brush, making sure the bristles overlap on 
the same side of the brush as before. See fi gure 25.
1.  Brushes set too low.
2.  Brushes are jammed
3.  Wheels are jammed.
Wheels skid when sweeping.
1.  Adjust height till brushes are 1/2" down 
into grass.
2.  Stop sweeper. Remove obstruction.
3.  Remove one wheel at a time to check for 
obstruction or damage. Refer  to Service 
and Adjustments section.
