Gearboxes, Walterscheid PTO shafts and clutches, Mechanics drive shafts, FC08 axles, HEX planetary drives and Rockford fan clutches. Version selection and a quotation for your machine.

Gearboxes for farm machinery

Comer Industries gearboxes cover speed change gears, right angle and parallel shaft drives, speed increasers and reducers. The range includes combine engine drives, round baler transmissions and Powershift units for feed mixers. Each version is engineered around the customer machine.

Track drive: 350–450 HP
Output torque: up to 33 kNm
Sugar cane drive: up to 216 kW
Cutterbar width: 2.5–3.7 m

Walterscheid PTO drive shafts and clutches

Under the Walterscheid brand the group makes PTO drive shafts plus overload and overrunning clutches. Shafts carry the QS lock and ST profiled guards, while the clutches protect the driveline from overload. The TAS tractor attachment system handles coupling and stabilising of implements.

Wide-angle joint: up to 80°
Power Drive joint P675
QS lock and ST guards
Clutches: overload protection

Mechanics drive shafts for off-highway machines

Mechanics Synergy and Legacy drive shafts serve off-highway machines and use quick-disconnect bearing technology. Double universal joints of the B, T and M series fit driven steering axles and marine stern drives. CDC and CV shafts handle non-aligned systems.

Legacy: 10.5C–20C series
DUJ B-Series: up to 60°
DUJ M-Series: bending up to 64°
CDC shafts: up to 50°

Axles with transmission and the FC08 series

Comer Industries builds steering and rigid axles with integrated transmission for combines, construction and material handling machines. The modular design allows hydraulic or electrical actuation and several brake and differential options. The FC08 series offers high power density.

FC08: rigid axle
Actuation: hydraulic or electrical
Brake and differential options
Electric drive versions

HEX planetary drives

Comer Industries planetary drives include modular wheel drives and slewing drives for mobile and stationary equipment. The HEX range is designed for excavator final drives and slew drives. Slew drives for wind turbines are offered as a separate line.

HEX: excavators 18–100 t
Final drive and slew drive
Several motor input options
Catalogues: PG and PGA series

ICVD hydrostatic traction drive

The ICVD travel drive is built around a hydraulic motor with large-angle technology. The continuously variable drive covers the whole speed range without interrupting tractive force. It is used in construction, material handling and forestry machines.

Hydraulic motor: 45° angle
Continuously variable drive
High traction from standstill
Simple drive reversal

Rockford fan clutches

Rockford introduced its first on-highway Class 8 truck fan clutch over 40 years ago and later applied the technology to off-highway machines. The clutches reduce fuel use and fan noise. They serve construction, road building, forestry and mining machines.

Experience: over 40 years
Programmed fan speed clipping
No shock load on the engine
Longer fan belt life

How to choose a Comer Industries transmission

Selection starts with the function of the unit in the machine.

A gearbox drives the working element of an implement, a PTO drive shaft links the tractor to the implement, an axle with transmission carries the machine and splits torque, a planetary drive handles travel and slewing, and the ICVD hydrostatic drive gives continuously variable travel.

Next come load and geometry: power and output torque for a gearbox, joint operating angle for a drive shaft, machine weight for a travel drive. For the track drive transmission the manufacturer lists 350–450 HP and up to 33 kNm, and the HEX drives cover excavators from 18 to 100 t.

Gearboxes and PTO shafts for farm machinery

Comer Industries gearboxes are engineered for a specific machine: a combine engine drive in an aluminium housing with integrated hydraulics and clutches, a round baler transmission with a free wheel, Powershift units for double and triple auger feed mixers, and a modular corn header gearbox with overload protection.

Walterscheid PTO drive shafts carry the QS lock and ST profiled guards, and the wide-angle joint briefly works at angles up to 80°. Overload and overrunning clutches protect the shaft, and the TAS system handles coupling, adjusting, stabilising and hitching of implements.

Mechanics drive shafts and DUJ joints

Mechanics Synergy and Legacy drive shafts are built for off-highway machines and use quick-disconnect bearing technology. Synergy needs no intermediate maintenance, and Legacy comes in the 10.5C–20C series. Round bearing drive shafts serve farm, construction and industrial applications.

B-Series double universal joints for driven steering axles work at angles up to 60°, and the M-Series for marine stern drives reaches a bending angle of 64°. CDC shafts suit non-aligned systems up to 50°, and CV shafts are truly homokinetic and maintenance free.

Axles and planetary drives

Steering and rigid axles with integrated transmission are modular, with hydraulic or electrical actuation and several brake and differential options. The FC08 series is compact for easy installation inside the machine, and integrated versions are offered for electric drive.

Planetary drives are split into modular wheel drives and slewing drives. The HEX range covers excavator final drives and slew drives for 18–100 t machines, with several motor input options and a custom pinion.

Slew drives with high torque density are made for wind energy, and the catalogues list PG and PGA modular planetary drives.

ICVD hydrostatics and Rockford clutches

The ICVD travel drive uses a hydraulic motor with a 45° angle. The continuously variable drive covers the whole speed range without interrupting traction, gives high tractive force from standstill and simple reversal. The manufacturer lists construction, material handling and forestry machines.

Rockford fan clutches grew out of a solution for on-highway Class 8 trucks introduced over 40 years ago. They cut fuel use and fan noise, reduce radiator sandblasting and remove shock load from engine components.
