Servicing the Hydraulic System

The machine’s reservoir is filled at the factory with

approximately 4-1/2 gallons (17 liters) of high quality

hydraulic fluid. 

Check the level of hydraulic fluid before

the engine is first started and daily thereafter. 

The

appropriate hydraulic oils are listed below.

The following list is not assumed to be all-inclusive.

Hydraulic fluids produced by other manufacturers may be

used if they can cross reference to find an equivalent to the

products listed. Toro will not assume responsibility for

damage caused by improper substitutions, so use only

products from reputable manufacturers who will stand

behind their recommendation.

Biodegradable Hydraulic Fluid—Mobil 224H

Important

Mobil EAL 224H is the only biodegradable

oil tested and approved by Toro. Contamination by

mineral–based hydraulic fluids will change the

biodegradability and toxicity of this oil. When changing

from standard fluid to the biodegradable type, be certain to

follow the approved flushing procedure published by

Mobil. Contact your Toro Distributor for details. The oil is

available in 5 gallon (19 l) containers from your Toro

Distributor, order part no. 100–7674.

Premium Biodegradable Hydraulic Fluid—Mobil EAL

EnviroSyn 46H

Important

Mobil EAL EnviroSyn 46H is the only

synthetic biodegradable fluid approved by Toro. This fluid

is compatible with the elastomers used in Toro hydraulic

systems and is suitable for a wide–range of temperature

conditions. This fluid is compatible with conventional

mineral oils, but for maximum biodegradability and

performance the hydraulic system should be thoroughly

flushed of conventional fluid. The oil is available in 5

gallon (19 l) containers or 55 gallon drums from your

Mobil Distributor.

Note:

 Many hydraulic fluids are almost colorless, making it

difficult to spot leaks. A red dye additive for the hydraulic

system oil is available in 2/3 oz. (20 ml) bottles. One bottle

is sufficient for 4–6 gal. (15–22 l) of hydraulic oil. Order

Part No. 44-2500 from your Authorized Toro Distributor.

This red dye is not recommended for use with

biodegradable fluids. Use food coloring.

traction unit used for mowing fairways, verticutting or used

during ambient temperatures 65

should have Oil Cooler Kit, Part No. 104–7701, installed.

Checking the Hydraulic System

Check the level of hydraulic fluid before the engine is

first started and daily thereafter.

1.

Position the machine on a level surface. Make sure the

machine has cooled down so the oil is cold.

2.

Remove the cap from the top of the reservoir and check

the fluid level. The fluid should be approximately

3-1/2 in. (89 mm) below the top of the fill hole

(Fig. 16).

3.

If the oil level is low, slowly fill the reservoir with ISO

VG 46/48 or equivalent hydraulic oil until the level is

up to the correct level. Do not mix oils.

4.

Install the cap.
