WARNING 5.2 How to Start the Mower Read and understand the safety instructions before attempting to operate your machine. Use caution when operating this piece of equipment. Practice operating the mower at low speeds and without the blades engaged until familiar with the operation of the controls.
5.4 How to Drive the Mower Over a Curb WARNING To climb a curb, first see the Safety Instructions section of this manual, especially the parts on: •Initial Operating Safety Guidelines •Operation In Reverse •Operation In Forward Direction To drive up and over a curb turn the blades OFF and then proceed forward to the curb, lift the front wheels off the ground by pushing down on the handlebar and move slowly forward allowing the front wheels to rest on the ground beyond the curb.
The wheels should now go to a neutral position if the steering control levers are locked using the thumb locks and/or the speed control lever is in neutral. 5.8 Straight Line Tracking Adjustments WARNING Verify that both rear tires are inflated to the proper PSI. Find a wide open flat area away from bystanders and objects. Drive the mower with the speed control set to the most used position. If the mower pulls to one side, return the speed control lever to neutral and shut off the engine.
6 Service and Adjustments 6.1 Tire Maintenance and Pressure WARNING 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 at the proper level. Higher pressures will cause the tires to have less traction which will force you to go slower, with less safety and give you a harder ride.
6.3 How to Move the Mower if the Engine Won’t Start Rotate both of the hydro bypass valve levers on the side of each hydraulic pump about ½ turn counterclockwise. It is important not to over tighten these levers. Damage may occur to the pump if this valve is over tightened. 6.4 Hydraulic System WARNING Whenever servicing the hydraulic system, it is of the utmost importance to keep any dirt or debris from getting into the system. Clean off all parts before disassembly and assembly.
6.7 Lubrication Grease with No. 2 general purpose lithium base or molybdenum base grease. • Set parking brake, stop the engine and remove the key. • Clean grease fittings with a rag. • Connect grease gun to fitting and pump until grease begins to ooze out from the bearings. • Wipe off excess grease. • Do not use spray lube of any kind on choke and/or throttle cables. •Service intervals: oFirst 8 hours oEvery 25 hours Also see Maintenance chart 6.
6.10 Spindle and Drive Pulley Split hub R&R • Remove 2, ¼” bolts from split hub and install in threaded holes in hub. • Slowly tighten each bolt, alternating as you tighten bolts against the pulley. • The hub will separate from the pulley. • Replace grade 8 bolts and install in reverse order using the assembly holes to tighten hub onto pulley and spindle shaft. Assembly hole Threaded Removal holes Tightening will separate the hub from the pulley Assembly hole 6.
1.75” – 3.0” 2.5” – 3.75” 3.25” – 4.5” Front Caster Coarse Adjustment 1.75” – 3.0” 2.5” – 3.75” 3.25” – 4.5” Rear Wheel Motor Coarse Adjustment •Temporary Height-of-Cut Adjustment: Using the caster shims (or spacers) you can adjust the blades downward temporarily .5” or 1” below the original coarse setting as described above. This assumes that the blades are level with two shims (or spacers) on the bottom and one shim on the top of the caster support arm.
6.13 Fuel Evaporation System All Wright Velkes need to have this mandatory feature. •Do Not alter or remove •Do Not fill past the “Max Fill Level” line shown in figure. •Over-filling could result in clogging the roll-over vent and/or contaminating the purge canister. •The vapor canister is located under the dash. •Inspect and clean dust filter every 500 hours or annually. To Tank Vent / Purge Max Fill Dust Filter 6.14 Transporting Use a heavy duty trailer or truck when transporting the Velke Hydro PG.
6.16 Cleaning the Mower The underside of the mower deck should be checked and cleaned twice daily and more often if the grass being mowed is lush or wet. The entire mower should be cleaned daily at the end of the work day. Cleaning should be done with a leaf blower or low-pressure compressed air. Wash with water only when necessary and do not use a pressure washer or nozzle as the water can enter bearings and electrical connections causing an electrical short, rust and corrosion.
