Belt Maintenance
Servicing the Alternator Belt
Chec k the condition and tension of the belts
( Figure 52 ) after ev er y 100 operating hours .
1. Proper tension will allo w 3/8 in. (10 mm)
deflection when a force of 10 lb . is applied on the
belt midw a y betw een the pulleys .
2. If the deflection is not 3/8 in. (10 mm), loosen the
alter nator mounting bolts ( Figure 52 ). Increase
or decrease the alter nator belt tension and tighten
the bolts . Chec k the deflection of the belt ag ain to
ensure that the tension is cor rect.

Maintenance
Changing the Hydraulic
Fluid
Chang e the h y draulic fluid after ev er y 800 operating
hours , in nor mal conditions . If the fluid becomes
contaminated, contact y our local T oro distributor
because the system m ust be flushed. Contaminated
fluid looks milk y or blac k when compared to clean oil.
1. T ur n the engine off and raise the hood.
2. Disconnect the case retur n line from the bottom
of the reser v oir and let the h y draulic fluid flo w
into a larg e drain pan. Connect the line when the
h y draulic fluid stops draining .
3. Fill the reser v oir with appro ximately 7.5 g allons
of h y draulic fluid; refer to Chec king the Hy draulic
Fluid in Operation , pag e 19 .
Important: Use onl y the h y draulic fluids
specified. Other fluids could cause system
dama ge.
4. Install the reser v oir cap . Star t the engine and use
all of the h y draulic controls to distribute h y draulic
fluid throughout the system. Also c hec k for leaks;
then stop the engine .
5. Chec k the fluid lev el and add enough to raise lev el
the lev el to the FULL mark on the dipstic k. Do
not o v erfill.
Replacing the Hydraulic
Filters
Chang e the 2 h y draulic filters initially after the first 200
operating hours . T hereafter , c hang e the filters after
ev er y 800 operating hours , in nor mal conditions .
Use T oro re placement filters P ar t No . 94-2621 for the
rear (cutting unit) of the mac hine and 75-1310 for the
front (c harg e) of the mac hine .
Important: Use of an y other filter may v oid the
w ar ranty on some components.
1. P osition the mac hine on a lev el surface , lo w er the
cutting units , stop the engine , eng ag e the parking
brak es , and remo v e the ignition k ey .
2. Clean the area around the filter mounting area.
Place a drain pan under the filter and remo v e the
filter ( Figure 53 and Figure 54 ).
3. Lubricate the new filter g ask et and fill the filter
with h y draulic fluid.
