INDIVIDUAL TINES REPLACEMENT
1.
While it is possible to replace only one tine at a time, it is recommended to replace tines in pairs on a tining arm.
2.
To replace tines, simply remove the 3/8” bolt that passes through the tining arm assembly. In this way, the tines can be
removed from the arm by sliding outward from the tining arm
3.
Remove the worn or broken tines from the assembly
4.
Inspect the bolt for wear, straightness, or thread damage. If the bolt is damaged, it should be replaced. This bolt is a
Grade 8 fastener. Replacing with a weaker bolt is not recommended.
5.
To re-install, place a washer,tine holder and then a tine onto the bolt. Now install these onto the tining arm with the open
side of the tine facing the rear of the machine. Once the bolt is through the tining arm, place another tine on the bolt, then a
tine holder. Finally, install a washer and nylon inserted lock nut. Tighten the assembly. Be carefull not to over tighten
which will bend the tine holders.
NOTE:
Tines are a normal wear item and should be inspected regularly for signs of wear or damage.
BELT AND CHAIN TENSION ADJUSTMENT
READ
all safety instructions before servicing unit.
DISCONNECT
spark plug wire before servicing unit.
ADJUSTING BELT TENSION-
1.
Proper belt tension needs to be maintained to prevent slippage during operation. When bail is fully actuated the length of
the coiled portion of the clutch cable spring should be 1.75”.
2.
If the clutch cable spring needs adjustment, loosen the jam nuts holding the cable on the handle assembly and adjust the
cable either in or out to shorten or lengthen the spring.
3.
Once proper adjustment is reached, tighten the jam nuts.
4.
Once adjustment is made, re-install spark plug wire and test adjustment. The machine hydraulic pump and transaxle
should dis-engage when the bail is released. There should be no evidence of belt slippage (reduced ground speed or slow
tine RPM) when operating the machine with bail engaged.
NOTE
: Never release the clutch on a slope. The unit is heavy and will free wheel downhill.
NOTE
: A worn belt will not allow for proper adjustment and must be replaced.
ADJUSTING CHAIN TENSION-
1.
Remove the hood (item 4) by removing the seven bolts, washers, and lock washers. (items 111,119,128), that secure it to
the tining frame.
2.
Locate the bolt (item 31, 33) and nut (item 80) that hold each chain idler sprocket to the tining frame of the unit. One idler
sprocket sets tension on the left tine drive chain and one sets tension on the right tine drive chain.
3.
Loosen the bolt and nut and slide the idler sprocket (item 29) in the desired direction.
INCREASED TENSION:
Slide the sprocket up.
DECREASED TENSION:
Slide the idler sprocket down.
4.
Tighten the bolt and nut to secure the sprocket in place.
5.
Replace the hood and reinstall the sevn bolts, washers, and lockwashers that secure it in place.
NOTE
: Over tensioning the chain will cause premature chain and sprocket wear. DO NOT OVER TENSION THE CHAIN. A properly
tensioned chain will have slack of 3/8"-1/2" when moved by hand.
