Checking Tire Pressure
 WARNING
Maximum tire pressure under any circumstances is 12 psi 
on rear tires and 25 psi on front tires. Equal tire pressure 
should be maintained at all times.
Inflation Pressure
Rear Tires — 10-12 psi max
Front Tires — 20-25 psi max
The tires on your tractor may be over-inflated for 
shipping purposes. Reduce the tire pressure before 
operating the tractor. Recommended operating 
tire pressure is 10-12 psi on rear tires and 20-25 psi 
on front tires.
Lubrication & Grease Points
Before operating the tractor, refer to the 
Product Care section of this manual to check the 
lubrication and grease points. Grease and lubricate 
if necessary.
Connecting the Battery Cables
 WARNING
California PROPOSITION 65: Battery posts, terminals, 
and related accessories contain lead and lead compounds, 
chemicals known to the State of California to cause cancer 
and reproductive harm. Wash hands after handling.
 CAUTION
When attaching battery cables, always connect the 
POSITIVE (Red) wire to its terminal first, followed by the 
NEGATIVE (Black) wire.
For shipping reasons, both battery cables on your 
equipment may have been left disconnected from 
the terminals at the factory. To connect the battery 
cables, proceed as follows:
1.  Using the lever on the back of the seat frame, lift 
up on the lever and tilt the seat forward locking 
it in place with the seat prop. Remove the bolts 
and hex nuts from the manual bag.
Note: The positive battery terminal is 
marked POS. (+) (a). The negative battery 
terminal is marked NEG. (–) (b). See 
Figure 2-20.
Note: If the positive cable grouping (c) is 
already attached, skip ahead to Step 6. See 
Figure 2-20.
2.  Locate the cables routed through the 
conduit along the inward facing side of 
the battery and separate the positive and 
negative groupings (each group will be 
zip-tied together).
3.  Slide the red boot (d), if present, back along 
the positive cable grouping. See Figure 2-20.
4.  Attach the positive cable grouping (c) 
and positive cable for the 12V outlet (if 
equipped) to the positive battery terminal 
(a) with the bolt (e) and sems nut (f). See 
Figure 2-20.
Note: Place the thickest cable closest to the 
battery terminal.

5.  Position the red boot (d) over the positive 
battery terminal (a) to insulate it and help 
protect it from corrosion. See Figure 2-20.
6.  Attach the negative cable grouping (g) 
and negative cable for the 12V outlet (if 
equipped) to the negative battery terminal 
(b) with the bolt (e) and sems nut (f). See 
Figure 2-20.
Note: Place the thickest cable closest to the 
battery terminal.
Note: If the battery is put into service after 
the date shown on top/side of battery, 
charge the battery prior to operating 
the machine.
