General Information Hydraulic Hoses Hydraulic hoses are sub ject to extreme conditions suc h as, pressure differentials during operation and exposure to weather , sun, chem icals, very warm st orage condi- tions or mish andling durin g operation or maintenan ce.
SAE Straight Thread O-Ring Port (Non-adjustable) (Fig. 3) 1. Make sure both threads and se aling surfaces are free of burrs, nicks, scr atches, or any foreign ma terial. 2. Always replace th e O-ring seal when this type of fitting shows signs o f leakage.
Hydraulic Flow Diagrams T raction, N o. 1 Position When engine is sta rted, pump draws oil from reservo ir through two suction lines. Oil from one section of pump passes through fitting in No. 4 spool valve into valve. T raction lever , when located in No.
T raction, No. 2 Po sition When the traction lever is positio ned in No. 2, flow from one pump section pa sses through same lines as for No. 1 traction position. This flow is joined by ad ditional flow from two other pump sect ions. The additio nal flow in- creases the RPM of the wheel motors to increase ground speed.
T raction, Reverse Positio n T raction lever is positioned in No. 1 or No. 2. When traction p edal is pushed rearward, flow from one pu mp section goes through No. 4 selector va lve section into No. 5 meterin g section and o ut the lines at th e front o f the valve to th e traction motors, wh ich drive the traction wheels, to operate in rev erse.
Reel Drive, Mowing Operation The MOW pedal is depressed, which causes the No. 1, 2 and 3 spools to be positioned fully out of va lve bank. This directs flow from one pump se ction to pass through left end cove r and out line le ading to left f ront cutting unit drive mo tor .
Reel Drive, Lower Cutting Units The MOW pedal is depressed to start reel drive opera- tion, flow fr om one pum p secti on passes th rough No. 3 spool section and out three lines, each leadin g to a lift cylinder . This actuates the lift cylinders and lowers the cutting un its.
Reel Drive, Raising Cutting Units When the LI FT pedal is depressed, No. 1, 2 and 3 spools are pushed inward. When sp ools pass neutr al, cutting units stop o peration. Ho lding peda l depressed keeps spools fully in. This dire cts flow from o ne pump section to pass th rough end cover and No.
Power Steering, R.H. T urn (Greensmaster 3100) Oil is supplied to port “P” of the steering contr ol unit from the pump steer ing section . When the stee ring wheel is turned to th e right, the contr ol section wit hin the st eering valve shifts to direct oil supplied by th e pump to th e metering section of the steering valve.

Special T ools NOTE: Order special too ls from the T O RO SPECI AL T O OL S AND A PPL I CA T I ONS GUI DE ( COM MERCI AL PRODUCTS ) . Some t ools may be listed in the Greensmaster 3100 Parts Catal og. Some tools may also be availab le from a local supp lier .
Seal Protector (Fig. 7 ) Slide the protecto r (Item 1) over the reel motor shaft before insta lling the shaft seal to pro tect the seal fr om damage. App ly a light coating of clean oil to the sea l protecto r to ease mo vement of the seal ove r the tools.
Seal Installation T ool (Fig . 9) Use to assure prop er fit and positionin g of lip seals used in the TRW T orqmotor hydraulic whe el motor . Put the seal inside the ring (Item 2) with the seal lip toward the motor . Slide the main tube (Item 1) of the tool in to the ring.
T roubleshooting The cause of an impr operly functioning hyd raulic sys- tem is best diagnosed with th e use of proper testin g equipment and a th orough unde rstanding of the com- plete hydraulic system. A hydraulic system with an ex cessive increase in heat or noise is a po tential failure .
