MAINTENANCE ________________________________________________________________________
The key to years of trouble-free service is to keep your Sweeper and Dethatcher Kit clean and dry.
Never allow wet material to remain in Hamper for extended periods of time.
Occasionally check all moving parts for free movement and, if necessary, lubricate with oil.
Should rust develop, sand lightly and then paint area with enamel.
Periodically check all fasteners for tightness.
TRACTOR/RIDING MOWER SPEED _________________________________________________________
The faster the Tractor/Riding Mower speed, the further the material is thrown into the Hamper. Operate at a speed that will throw material
to the back of the Hamper. Under normal conditions, 3-4 M.P.H, or the speed of a brisk walk.
To calibrate your tractor to 3 m.p.h.:
• Measure a distance of 20 feet on a fl at, level surface.
• Adjust tractor throttle and select a gear to cover this distance in 4.5 seconds
• To adjust for 4 m.p.h., cover the same measured distance in 3.4 seconds.
OPERATION: ____________________________________________________________________________
The use of the Dethatcher-Sweeper combination will accomplish Thatch removal and Sweeping at the same time. When adjusted properly ,
the Dethatcher is designed to comb through your lawn-fl ipping out harmful Thatch and collecting it in the Hamper. Tines can be lowered to
actually contact ground for more aggressive operation (such as seedbed preparation, etc.). Refer to Fig. 6. For best results, lawn should be
normal height (not too high) and relatively dry prior to Dethatching.
If you prefer to operate the Sweeper only, simply move the Lift Handle to the vertical position (Tines facing to REAR).
