Fertilizer Spreader PTO Gearbox Overview<\/h2>\n

The L-25J is a lightweight aluminium-housed riduttore della presa di forza<\/b> engineered for fertilizer broadcasting equipment, band saw drives, and small mower applications. This riduttore per presa di forza agricola<\/b> delivers a 1:1.9 speed-increasing ratio (or 1.9:1 in reducing mode), converting the 540 RPM PTO input into the higher shaft speeds that spreader discs and distributor mechanisms require for even material dispersal. Maximum output torque reaches 22.7 daNm, and the increasing configuration handles up to 11 kW (15 HP) of input power \u2014 well-matched to the 20-40 HP compact tractors widely used on Korean vegetable farms, greenhouses, and orchard operations.<\/p>\n

Questo Sostituzione del riduttore della presa di forza<\/b> is manufactured as a direct dimensional match for the Comer Industries L-25J. Every critical interface \u2014 input spline (1 3\/8-inch, 6-spline Type A), output shaft (22 mm Type D), and housing mounting face \u2014 mirrors the original design. The aluminium housing holds total weight to just 4.1 kg, a practical advantage on smaller tractors where implement weight affects three-point hitch balance and fuel consumption. The gearbox ships dry, giving operators flexibility to choose their preferred 80W-90 lubricant and fill the 0.35 L reservoir before first use.<\/p>\n

Korea Ever-Power PTO Shaft Co., Ltd produces this gearbox under ISO 9001-certified quality controls with individual bench testing for gear noise, seal integrity, and dimensional accuracy. Our Korea-based logistics delivers within 2-4 business days nationwide, with same-day dispatch on orders confirmed before 2 PM KST.<\/p>\n

Specifiche tecniche<\/h2>\n

The table below lists verified performance parameters for this riduttore della presa di forza del trattore<\/b>. All torque and power figures correspond to standard 540 RPM PTO input. The aluminium housing provides natural corrosion resistance \u2014 important when handling chemical fertilizer materials \u2014 combined with adequate structural rigidity for this power class.<\/p>\n

Structure and Material Engineering<\/h2>\n

Housing and Sealing Design<\/h3>\n

The L-25J uses a two-piece aluminium alloy housing that splits along the gear plane, secured by precision-machined mating faces and high-strength cap screws. Aluminium was selected for this riduttore della presa di forza<\/b> application class because fertilizer spreading equipment benefits from low weight (reducing hitch load on sub-30 HP tractors) and natural corrosion resistance when exposed to chemical dust and moisture. The housing walls maintain concentricity within tight tolerances to keep gear mesh geometry consistent across the full service life of the unit.<\/p>\n

Gear and Bearing Assembly<\/h3>\n

Inside, a pair of spiral bevel gears transfers power through a 90-degree turn. Gear teeth are precision-ground after heat treatment, producing a surface finish that supports a stable oil film at the contact zone. Taper roller bearings on both shafts absorb the combined radial and axial loads from the bevel mesh. The input shaft seal uses a double-lip nitrile rubber design rated for the temperature swings common in outdoor agricultural work. The output seal includes an additional dust lip to keep abrasive fertilizer particles out of the bearing cavity. A magnetic drain plug captures ferrous wear particles, serving as a visual indicator of internal wear at each oil change.<\/p>\n
