Special Features:
• Pin mounts exclusively to the Toro Workman 3000 & 4000. Four pins secure the sprayer to the vehicle pin system. Only five minutes or less is required to remove the four pins and two hydraulic quick couplers and the sprayer is ready to lift off.
• Custom molded fiberglass tank with red gel coat.
• SDI’s off-set filler opening – makes filling from ground level easy (only 47" from ground to filler opening).
• 30 GPM diaphragm pump handles all spray chemicals including aggressive iron products, spray dyes, and can even be run dry without damage to the pump!
• Maximum spray pressure of 200 PSI exceeds all turf spraying requirements and provides adequate pressure for “Walking Spray Booms” at the end of 200 feet of 1/2" hose.
• SDI's “Hydro-Mix” six orifice jet agitator with ceramic tips out performs most paddle (mechanical) agitation systems and can be adjusted to minimize foaming by changing of tip size or restricting inlet flow.
• Daily maintenance of the sprayer is very easy due to OPTIMUM accessibility of the top mounted pump and plumbing. The Toro Workman vehicle engine compartment is readily accessible by raising the sprayer's front end using the hydraulic lift cylinder.
• Deep sump suction system assures complete emptying of spray material.
• Add SDI's Convertible (15/21 foot) OPTIMUM Turf Boom, motorized boom controls, and SDI's manual electric controls or Raven 330 or 440 spray control system to complete the OPTIMUM Spray System.
