What Is the Vertical Feed Mixer Gearbox PGA1202VM?<\/h2>\n

The Vertical Feed Mixer Gearbox PGA1202VM is a precision-engineered power transmission unit designed to replace Comer Industries’ original PGA1202VM gearbox. Mounted directly to a tractor’s PTO shaft \u2014 operating at either 540 or 1000 RPM \u2014 it converts tractor engine output into the optimal speed and torque required for vertical auger-style feed mixing. Whether your operation runs a single mixer of 10\u201314 m\u00b3 or a twin-auger system of 16\u201324 m\u00b3, this gearbox delivers the mechanical muscle your mixing wagon demands.<\/p>\n

Why UK Farms Choose This Gearbox<\/h2>\n

Six performance advantages that justify the investment<\/p>\n

\n
\n
\u2699<\/div>\n

Uniform, Consistent Mixing<\/h3>\n

The high-torque output ensures every batch is blended evenly from edge to core. Animals receive nutritionally balanced feed with each meal, which directly translates into improved daily weight gain, healthier livestock, and \u2014 for dairy herds \u2014 measurably better milk yields. No hot spots, no segregation of heavier ingredients.<\/p>\n<\/div>\n

\n
\ud83d\udcc8<\/div>\n

High Mechanical Efficiency<\/h3>\n

Engineered to deliver maximum torque at the low output speeds that heavy feed mixing demands, this vertical feed mixer gearbox reduces cycle times and cuts PTO fuel burn. For farms running two or three mixing sessions per day, the savings in tractor hours quickly offset the initial replacement cost \u2014 a calculation UK operators repeatedly confirm.<\/p>\n<\/div>\n

\n
\ud83d\udee0<\/div>\n

Built for British Farmyard Conditions<\/h3>\n

Cast iron housing, hardened steel gears, and reinforced lip seals work together to handle the moisture, chaff, and fine dust that are unavoidable on UK dairy and arable farms. Whether you’re mixing silage-based TMR in a Yorkshire winter or processing dry concentrates on a Hampshire arable unit, this gearbox won’t flinch.<\/p>\n<\/div>\n

\n
\ud83d\udd27<\/div>\n

Simplified Maintenance Schedule<\/h3>\n

A well-documented oil change programme \u2014 first service at 50\u201370 hours, then every 500\u2013700 hours or annually \u2014 keeps internal components in peak condition without complex tooling. The integrated spindle bearing removes one external assembly from the maintenance checklist entirely, shortening workshop time and reducing the stock of spare parts you need to hold on-site.<\/p>\n<\/div>\n

\n
\ud83c\udfed<\/div>\n

Versatile Application Range<\/h3>\n

From compact 10 m\u00b3 single-auger wagons used by family-scale farms to 24 m\u00b3 double-auger rigs on large commercial beef units, this gearbox covers the full spectrum of mixing wagon sizes. It’s equally at home powering livestock feed mixing, poultry ration blending, aquaculture pellet production, and even bulk fertiliser mixing operations.<\/p>\n<\/div>\n

\n
\ud83d\udd04<\/div>\n

Drop-In Comer PGA1202VM Replacement<\/h3>\n

Designed as a direct, dimensional replacement for the Comer PGA1202VM, this unit fits existing mounting points and PTO shaft interfaces without modification. Farms already running Kuhn, Trioliet, Jaylor, Storti, or Schuler mixing wagons can swap the gearbox without fabrication work, getting their machine back in service faster and minimising harvest-season downtime.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

<\/p>\n

\n

How It Works \u2014 Inside the PGA1202VM Gearbox<\/h2>\n

Power path from tractor PTO to mixing auger<\/p>\n

\n
\n
01<\/div>\n

PTO Engagement<\/h3>\n

The tractor operator engages the PTO lever, transferring rotational power at 540 or 1000 RPM through the drive shaft into the gearbox input.<\/p>\n<\/div>\n

\n
02<\/div>\n

Helical Gear Transmission<\/h3>\n

Hardened helical gears inside the cast iron housing reduce speed while multiplying torque \u2014 providing the low-speed, high-force output that heavy feed mixing demands without generating excessive heat.<\/p>\n<\/div>\n

\n
03<\/div>\n

Bearing Support<\/h3>\n

Precision-grade bearings carry radial and axial loads on both input and output shafts, reducing friction and preventing shaft deflection under full torque \u2014 critical for long service life in dusty farm environments.<\/p>\n<\/div>\n

\n
04<\/div>\n

Direct Spindle Drive<\/h3>\n

The output shaft connects directly to the mixer’s screw spindle via the integrated bearing assembly, eliminating intermediate couplings. This direct drive reduces power loss and mechanical play \u2014 producing crisper, more responsive auger control.<\/p>\n<\/div>\n

\n
05<\/div>\n

Sealed for Life<\/h3>\n

Reinforced oil seals and precision-fitted gaskets throughout the housing prevent lubricant loss and block contaminants. The cast iron casing acts as the final barrier, protecting the gear train from impact, vibration, and corrosive splashback.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

<\/p>\n

\n

Common Applications Across UK Agriculture<\/h2>\n

Where the Vertical Feed Mixer Gearbox PGA1202VM delivers real-world results<\/p>\n

\n
\n

Beef & Dairy TMR Mixing<\/h3>\n

Powers total mixed ration (TMR) wagons on beef finishing and dairy units throughout England, Scotland, and Wales \u2014 ensuring each cow receives a consistently blended diet every time the wagon passes.<\/p>\n<\/div>\n

\n

Poultry Feed Blending<\/h3>\n

Handles the specific bulk densities and finer textures of broiler and layer rations, delivering the precise, homogeneous blends required by modern poultry production protocols.<\/p>\n<\/div>\n

\n

Aquaculture Feed Production<\/h3>\n

Used in fish feed pellet manufacturing where thorough integration of vitamins, minerals, and binders into a carrier matrix is essential for aquatic animal health and growth performance.<\/p>\n<\/div>\n

\n

Fertiliser Blending<\/h3>\n

Heavy-duty mixing of compound fertiliser components requires the same torque characteristics as feed work. This gearbox handles abrasive granular inputs without excessive wear on the internal gear train.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Dairy Farming | Yorkshire, UK<\/div>\n<\/div>\n

Holt Green Farm, North Yorkshire \u2014 320-Cow Dairy Unit<\/h3>\n

In early 2023, Holt Green Farm was running a 16 m\u00b3 double-auger Jaylor mixing wagon when the original Comer PGA1202VM gearbox began showing signs of bearing failure \u2014 intermittent noise on engagement and a progressive drop in mixing consistency. With the spring calving block approaching, the farm manager needed a fast, reliable solution that wouldn’t require the wagon to be sent away for re-engineering.<\/p>\n

After ordering a replacement PGA1202VM-compatible gearbox through agriculturalgearboxes.top, the unit arrived within five working days. Installation was completed by the farm’s own mechanic in under three hours using standard workshop tooling, with no fabrication required. The integrated spindle bearing assembly was a particular advantage \u2014 it meant one fewer component to source separately and one fewer potential failure point going forward.<\/p>\n

Twelve months on, the gearbox is performing without issue. The herd’s milk production has remained consistent, which the farm’s nutritionist attributes in part to the restored mixing uniformity. The total cost of gearbox replacement \u2014 including oil \u2014 was recovered in under two months relative to the projected decline in yield from uneven TMR.<\/p>\n<\/div>\n

“We run a 650-head beef finishing unit in Lincolnshire and can’t afford mixing wagon downtime during housing season. The replacement gearbox dropped straight in, oil filled, and it’s been faultless for eight months. Wouldn’t hesitate to order again.”<\/p>\n
