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. 1, positions spool so oil is directed to flow into the No. 5 meterin g valve section. When th[...]

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. Hydrauli c Flow Dia grams P ag[...]

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. G[...]

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 . Flow causes mo tor to tu rn, driving re el. Flow from separate pump secti[...]

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. Oil is ret urned to a th ree-way fitting o n the No. 1 spool section thr[...]

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. 1 sp ool valve , out three lines leading to lift cylind[...]
