This specification document outlines the technical requirements for a trailer-mounted hydro seeder to be procured by Department 591 under RFP No. 180000000740, with the reference model being a Finn T90T Hydro Seeder. The unit must be new and in current production, featuring a 940-gallon tank capacity with 800-gallon working capacity, a diesel Tier IV Final compliant 3-cylinder 35 horsepower water-cooled engine, and a centrifugal 4-inch by 2-inch pump rated at 170 gallons per minute at 100 PSI. The equipment specifications are comprehensive and detailed, covering electrical systems, instrumentation with NEMA 6-rated control boxes and IP67-rated switches, operator station features including keyed ignition and hour meter, tank construction using 7-gauge steel with continuous welds, and a discharge boom capable of reaching up to 180 feet. The trailer component includes tandem axles with 7,000-pound capacity, dual rubber torsion suspension, a 3-inch pintle hook rated at 20,000 pounds, DOT-approved LED lights, and electric brakes on both axles.

The specification mandates specific material standards and finishes, including abrasive shot blasting to SSPC-SP10/NACE 2 specifications with targeted mil profiles and paint coating requirements using Axalta and Carboline products with defined mil thickness ranges. The unit must accommodate a maximum material capacity of 2,500 pounds of granular solids and 400 pounds of fiber mulch, feature four types of spray nozzles for variable application, and include a reversible hydraulic agitator system with variable speed control from 0-100 RPM. The hydraulic system requires a pump delivering 7.46 GPM at 2709 RPM with electronically driven safety pressurization and pressure-limited flow control valves set to relieve at 2100 PSI. Contractors must respond with "YES" to each specification section or provide detailed explanations and alternative options if unable to comply with any requirement.
