WARNING User Clothing: DO NOT operate the mower while wearing sandals, tennis shoes, sneakers, or shorts. Always wear long non-baggy pants. Wear hightop leather work boots with thick, textured tread, soft-rubber soled at all times. Hard or smooth soled shoes are too slippery for a good footing on mower platform. NEVER wear loose-fitting clothing or jacket pockets that can get caught to the handlebars or control levers of any mower you drive.
• Before attempting to start the engine, follow all starting instructions below and in the engine operator’s manual. • Look behind before backing up. • Before leaving the operator’s position, even momentarily, turn off the blade clutch engagement switch and apply the parking brake. Keep others from coming near the mower. Get back on the mower as soon as possible.
WARNING Operation on Slopes DO NOT operate on steep slopes. Do not operate the mower on slopes steeper than you can feel secure about the traction of the tires and the stability of the mower. Do not operate the mower on slopes at all when the grass is wet. There is a danger of suddenly sliding sideways or down the hill. When operating on a slope, travel across the grade whenever possible, not in an up or down pattern.
WARNING Replacement Parts Use of parts other than specified parts supplied by Wright Manufacturing, Inc. may compromise the safe use of the mower, are not recommended and their use could void the warranty. Always check with your Dealer or the Wright Mfg website for the latest Illustrated Parts List for your equipment. Wright is fully concerned with your safety.

REMEMBER THERE ARE CERTAIN PRECAUTIONS LISTED IN THIS MANUAL THAT YOU MUST NOW TAKE BEFORE STARTING THE MOWER. Inspect Mower Before Each Use Inspection of Mower: Do not use the mower if any parts are not maintained in good operating condition. Examine all moving parts prior to each use.
How to Drive the Mower Over a Curb To climb a curb, first see the Safety Instruction Manual section of this manual, especially the parts on: •Initial Operating Safety Guidelines •Operation In Reverse •Operation In Forward Direction Next, raise the mower deck into the locked transport position. This is the highest position for the mower deck.
the pump in the Return-To-Neutral position, the lower rod end should be at the same height as the rigidly fixed ball joint connected on the same end of the torsion rod. Perform this adjustment on both the right and left side. Now that the lower end of both torsion rods are level, proceed to the upper control rods connected to the control levers. Loosen the jam nuts on both ends of the upper control rod. Note: the Speed Sensitivity setting should be set to the fast position. See previous section.
WARNING Service and Adjustments Tire Maintenance and Pressure Excessively worn tire tread is dangerous on all hills. Replace drive tires with less than 3/32” of any tread groove left. Use tires with the tread pattern recommended by Wright Mfg., Inc. only. Keep the tire pressure in the drive tires between 18 and 24 psi. Higher pressures will cause the tires to have less traction which will force you to go slower and with less safety and give you a harder ride.
Bleeding Air from the Hydraulic System Whenever servicing the hydraulic system, it is of the utmost importance to keep any dirt or debris from getting into the system. When any of the hydraulic parts are disconnected or removed or when the oil is changed, air must be bled from the system. If air is entrained in the system, loss of power, excessive heat, and damage to the hydraulic pumps may occur. First, make sure the oil level in the reservoir is correct.
