Przegląd produktu

The Post Hole Digger Gearbox is a vital component in agricultural machinery, delivering reliable power transmission for tasks like fence post installation and orchard planting. Our Comer Code T-22F replacement gearbox is engineered for demanding fieldwork, with a compact design and smooth power delivery that keeps your equipment running efficiently across various soil conditions.
Key Features and Benefits
Efficient Power Transmission
This agricultural gearbox features an optimized gear profile with over 92% transmission efficiency, ensuring steady and powerful output. It maintains consistent auger speed even in heavy clay or rocky soils, significantly boosting digging speed and overall productivity.
Premium Materials and Craftsmanship
Gears and shafts are made from 40Cr alloy steel, carburized and quenched to a surface hardness of HRC58-62 while retaining excellent core toughness. The housing is crafted from high-strength ductile cast iron and precision-machined on CNC equipment, achieving coaxiality tolerances under 0.02mm for superior wear resistance and impact durability.
Exact Match for Comer Code T-22F
Built to a 1:1 scale from Comer’s original blueprints, every detail—input/output shaft diameters, keyways, and spline specs—matches perfectly. Bolt patterns align precisely, so you can swap it in without modifying mounts or couplers, minimizing downtime.
Applications
Agricultural Equipment
Ideal for tractor-mounted post hole diggers, hydraulic augers, tree-planting drills, soil samplers, and even small-scale foundation work.
Diverse Working Environments
From soggy rice paddies in the south to frozen ground up north, or sloped orchards in hilly regions, this farm gearbox performs reliably. With an IP65 rating, it operates smoothly from -20°C to 50°C and shrugs off rainy-season mud.
Powiązane akcesoria
PTO Safety Guard : Heavy-duty stamped steel guard with black powder-coat finish; mounts via four M10×25 bolts (included) directly to the gearbox input flange. Fully encloses the 1-3/8″ (6-spline) PTO shaft connection, preventing debris ingress and reducing operator exposure to rotating components.
Auger Adapter Flange : Precision-machined cast steel flange with 2″ (50.8 mm) round bore and 1/2″-13 UNC shear bolt hole (Grade 2 shear bolt supplied). Matches standard 2-9/16″ (65 mm) bolt circle on auger hubs; includes four M12×35 Grade 8.8 hex bolts, spring washers, and torque spec label (80 N·m).
90W-140 GL-5 Gear Oil : Fully synthetic, SAE J306-certified extreme-pressure gear lubricant; 1-liter bottle pre-measured for the gearbox’s 3.3 L initial fill (to midpoint of sight glass). API GL-5 rated, suitable for -15°C to 50°C operating range.
Magnetic Drain Plug: Forged steel M18×1.5 threaded plug with neodymium magnet tip ; collects ferrous wear particles during oil drainage. Includes copper crush washer for leak-free sealing; torque to 35 N·m.
Cross & Bearing Kit : Greaseable universal joint kit for 1-3/8″ 6-spline yoke (Comer Series 5 profile); includes cross trunnion, four bearing cups with needle rollers, circlips, and zerk fitting. Pre-packed with lithium-complex NLGI 2 grease; rated for 540 r/min continuous duty.

Instalacja i konserwacja
Przewodnik instalacji
Prep the mounting surface, confirm shaft alignment within 0.5mm, and apply lithium-based grease to the splines. Tighten bolts clockwise to 80–90 N·m. After the first 30-minute run-in, check oil level and top up with GL-5 85W-140 gear oil.
Maintenance Tips
Inspect oil level every 100 hours of operation; replace oil every 500 hours or six months. Clear mud from the cooling fins regularly to prevent overheating. Stop immediately if you hear unusual noise and inspect to avoid minor issues escalating.
Why Choose Us 5.1 Proven Quality
Every unit undergoes a 48-hour full-load break-in test, keeping noise below 75 dB and temperature rise under 45°C. Backed by a 12-month warranty—non-human-related defects are replaced free of charge.
Expert Support
Round-the-clock phone and WeChat technical assistance, plus step-by-step videos and troubleshooting guides. Our seasoned farm-machinery engineers offer remote guidance to get you back to work fast.
Często zadawane pytania
What gear oil should I use for the T-22F gearbox?
Use GL-5 85W-140; fill to the midpoint of the sight glass or dipstick after the first 30-minute run-in.
How do I align the gearbox during installation?
Keep input-to-output shaft misalignment under 0.5 mm and tighten mounting bolts to 80–90 N·m in a cross pattern.
When should I replace the lubricant?
Check oil every 100 hours; change it every 500 hours or 6 months, whichever comes first.
Will this gearbox fit my older Comer T-22F unit?
Yes—shaft diameters, splines, keyways, and bolt patterns match the original 1:1, so no modifications are needed.
