The Trac Vac PTO systems can accommodate front or mid-driven mowers on compact tractors with a minimum of 13.5HP at rear PTO. Trac-Vac Model 858 vacuum runs off the tractors 540 RPM PTO and mounts on drawbar. It has 8” intake and exhaust hoses and has a large 44-bushel capacity. It's supported by a stabilizer arm on the three point to free-lift arms for raising and lowering the mower. Features include a 2-to-1 gearbox coupled to the turbine assembly with belt drive producing a turbine speed of approximately 3800 RPM. The Model 858 comes standard with a 18 cubic foot dump cart tapered four inches front to back to allow debris to fall out quickly with little clogging. **Lift kit additional if required. The 20-gauge all steel cart cover, powder coated for long life, expands capacity to approximately fifty cubic feet. The 858 has eight-inch intake and exhaust hoses which can move leaves, grass clippings, and light litter with less chance of clogging. The six-bladed forward curve turbine reduces noise to a pleasing 70 decibel level while reducing the clippings and leaves for better compaction in the collection container. Note: Most tractors require a special lift kit to bypass the stabilizer arms as the lift mechanism for the mower deck. Check with your distributor for these applications.
