• Product: SC-9.311-B
• Category: Flail Mower Gearbox
• Model or reference: SC-9.311-B
• Key specifications: Parts: SC-9.311-B; Delivery Time: 15 days; Min. Order: 10 Pieces

• Tell us the machine type, working environment, and target application so the product can be matched to the actual field load.
• Share drawings, shaft size, mounting dimensions, ratio, torque, blade diameter, or other known specifications when they are available.
• For replacement projects, photos of the existing part and nameplate information help confirm compatibility before quotation.
• If the part is a gearbox, include input speed, output speed, rotation direction, lubrication method, shaft diameter, bolt spacing, and any existing ratio marking on the housing.
• If the part is a blade or disc, include outside diameter, center bore, hole count, thickness, concavity, edge type, and the machine model where it will be installed.
• If the part is used in heavy soil, rocky fields, wet crop residue, or long daily shifts, explain those conditions because shock load and sealing needs may affect the recommendation.
• For a sample-based review, send one overall machine photo, one close-up of the installed part, one nameplate photo, and one measurement photo with a ruler or caliper in frame.
• For repeat purchasing, include the expected annual quantity, first order quantity, destination country, packaging request, and deadline so the reply can cover both technical fit and supply planning.
• Record ratio marks such as 1:1, 1:1.46, 1:1.93, or 1:2.83 if they are visible on the casting, label, or old quotation.
• For PTO-related work, confirm whether the machine uses 540 rpm, 1000 rpm, 6-spline, 21-spline, triangular tube, lemon tube, shear bolt, or overrunning clutch details.
• For mounting checks, measure overall width, height, depth, shaft protrusion, center distance, hole diameter, bolt count, and the distance from shaft center to the mounting face.
• If the existing part failed, list the observed symptom and timing, for example oil leak after 30 hours, bearing heat after 80 hours, worn spline after 1 season, or cracked housing during rocky-field work.
• For packaging and shipment planning, include carton quantity, pallet limit, private label request, barcode need, destination country, port, and whether the order is for trial, stock, or OEM assembly.
• For this product page, compare the displayed model with any code on your machine, such as SC-01-084, SC-01-229, SC-RV010, GT40U, 650PHD, or 2300058, then match shaft size, bolt count, mounting face, and product category before sending the form.
• If you are replacing a gearbox from another supplier, include old ratio, oil grade, bearing noise, seal leakage, housing temperature, and whether the part worked on a 3-point hitch implement, trailer machine, mower, digger, spreader, or rake.

If the standard configuration is not an exact match, our team can review custom gearbox, blade, or drive-line requirements and reply with the practical next step. A short note about why the original part failed, such as oil leakage, worn splines, cracked housing, or bent disc edge, helps the review focus on durability instead of only shape matching.
