to search for leaks. Hydraulic fluid escaping under pressure can have sufficient force to penetrate the skin and cause serious injury. • Before disconnecting or performing any work on the hydraulic system, all pressure in the system must be relieved by stopping the engine and lowering the cutting units to the ground. • If the engine must be running to perform a maintenance adjustment, keep hands, feet, clothing, and any parts of the body away from the cutting units, attachments, and any moving parts.
Safety and Instructional Decals Safety decals and instructions are easily visible to the operator and are located near any area of potential danger. Replace any decal that is damaged or lost. 107-2916 1. Remove the ignition key and read the Operator’s Manual before servicing or performing maintenance. 2. Thrown object hazard—do not operate the mower with the deflector up or removed, keep the deflector in place; keep bystanders a safe distance from the machine. 3.
105–9551 1. Warning—read the Operator’s Manual. 2. Lower the cutting deck when traveling down slopes. GM225 unites require 25 kg (55 lbs) of rear weight.

3. Remove the 2 bolts and lock washers securing the PTO guard mounting brackets to the gear box (Figure 8). Retain the fasteners for future installation. Figure 8 1. PTO guard 2. Gear box Figure 9 4. Slide the PTO shaft guard onto the PTO shaft, positioning the guard as shown in Figure 8. 1. 2. 3. 4. 5. 5. Slide the male PTO shaft into the female PTO shaft. Align the gear case input shaft with the PTO shaft and slide them together. Secure them with the roll pin and tighten the bolts and locknuts.
4 Installing the CE Decal Parts needed for this procedure: 1 Decal Procedure Apply the deal to the cutting unit for CE compliance 5 Installing Rear Weight No Parts Required Procedure Two Wheel Drive Groundsmaster 200 Series, 3280-D, and 3320 traction units comply with the ANSI B71.4-2004 Standard when equipped with rear weight. Refer to the chart in the traction unit Operator’s Manual to determine the combinations of weight required. Order the parts from your local Authorized Toro Distributor.
Product Overview Operation Specifications Note: Determine the left and right sides of the machine from the normal operating position. Note: Specifications and design are subject to change without notice. Adjusting the Height-of-Cut Width of 51-3/4 inches (1.314 m) Cut Height of Cut Adjustable from 1 to 4 inches (25 to 102 mm) in 1/2 inch (13 mm) increments Blade Tip Speed 15,525 ft/minute @ 3250 engine RPM Cutting Blades 3 heat-treated steel blades, each 3/16 inch (4.
Checking the Gear Box Lubricant Using the Grass Deflector The gear box is designed to operate on SAE 80-90 wt. gear lube. Although the gear box is shipped with lubricant from the factory, check the level before operating the cutting unit. 1. Position the machine and cutting unit on a level surface. Without the grass deflector mounted in place, you and others are exposed to blade contact and thrown debris. Contact with the rotating mower blade(s) and thrown debris will cause injury or death 2.
Maintenance Lubrication The cutting unit must be lubricated regularly. If the machine is operated under normal conditions, lubricate the castor bearings and bushings with No. 2 general purpose lithium base grease or molybdenum base grease after every 8 hours of operation or daily, whichever comes first. All other bearings, bushings, and the gear box must be lubricated after every 50 hours of operation. Figure 15 1. Lubricate the following areas: 2.
1 2 Figure 17 1. PTO shaft G010553 Figure 18 If the engine is started and the PTO shaft is allowed to rotate, serious injury could result. 1. Lynch pin Do not start the engine and engage the PTO lever when the PTO shaft is not connected to the gear box on the cutting unit. 2. Thrust washers 5. Apply grease to the inside and outside of the new bushings. Using a hammer and flat plate, drive the bushings into the mounting tube. 5.
2. Tip the wheel to the side and allow the spanner bushing (Figure 19) to fall out. G010549 Figure 20 3. Rotate the opposite end of the blade forward. Measure between the cutting unit and cutting edge of the blade at the same position as in step 2The difference between the dimensions obtained in steps 2 and 3 must not exceed 1/8 inch (3 mm). If the dimension exceeds 1/8 inch (3 mm), replace the blade because it is bent; refer to Removing the Cutting Blade. Removing the Cutting Blade Figure 19 1.
2 Figure 22 1 1. Cutting edge 2. Curved area/sail G010555 3. Wear/slot forming 4. Crack Figure 21 1. Blade bolt 2. Anti-scalp cup 3. Install the blade-sail facing toward the cutting unit-with the anti-scalp cup and blade bolt. Tighten the blade bolt to 85-110 ft-lb (115-149 N-m). If the blade is allowed to wear, a slot will form between the sail and flat part of the blade (Figure 22).
Checking and Correcting Mismatch of Blades 8. Compare the measurements at various positions. All dimensions must be equal within 1/4 inch (6 mm) from any 2 adjacent blades. The difference between the dimensions of all 3 blades must not exceed 3/8 inch (10 mm). If the difference exceeds specifications, proceed to step 9. If one cutting blade cuts lower than the others, correct them as follows: 1.
Adjusting the Idler Pulley D. Transfer one thrust washer from the lower side of the castor shaft to the top side, install the assembly, and compare the blade height of all of the blades; refer to steps 3 through 7. Repeat the procedure if the height still does not meet the requirements. E. If the height is within the specified dimension, install the lynch pin, set the height-of-cut to the proper height, and resume operation.
1. Position the machine on a level surface, lower the cutting unit, engage the parking brake, put the traction pedal in neutral, the PTO lever in the Off position, shut the engine off, and remove the ignition key. 2. Release and unhook the latches securing the covers to the top of the cutting unit. Remove the covers. 3. Loosen the 2 nuts securing the idler plate in place and remove the old belt from the pulleys. 4. To install a new belt, the gear box base must be removed.
Troubleshooting Problem The cutting unit will not cut or cuts poorly. Possible Cause Corrective Action 1. The blades are dull. 1. Sharpen the blades. 2. One or more blades are bent or damaged. 3. The spindle bolts are loose. 2. Replace the blades. 4. The cutting unit belts are loose or broken. 5. The gear box pulley is loose. 6. A gear box shaft is broken. 7. The PTO belt is broken. 8. The PTO pulley is loose or broken. 9. The PTO shaft is broken. 10.
