Overview
The Lexion 450 uses the Cat 3126 diesel engine at 250 horsepower. The Lexion 450 features the patented Accelerated Pre Separation (APS) threshing system paired with straw walkers for separation. Like on all Lexion combines, the 450 offers a great amount of adjustability from the cab. Operators can make changes such as sieve opening and fan speed from the cab and see the effects of those changes on the in-cab monitor. Design enhancments and fewer stops to make adjustments, mean more acres harvested per day with Lexion combines.

Benefits & Features
Header and Feederhouse
Header
The heads and headers available for Lexion combines offer many features that compliment the performance of the combine.
Feederhouse
The long and wide feederhouse on the Lexion 450 give the operator excellent visibility and ensures smooth crop flow to the threshing and separating systems.
Threshing and Separation Systems
Threshing
The exclusive Accelerated Pre Separation (APS) threshing system increases capacity. Normally, to get fast harvest speeds you have to either give up grain quality or accept higher losses - not with Lexion combines.
Separation Systems
Caterpillar combines raise the standard for straw walker performance, letting you harvest at higher speeds without increasing losses.
Sieves and Cleaning System
Two-Piece Preparation Pan
The preparation pan is in two halves; each section is removable from the front.
Twin Ventilated Sieves
The upper ventilated step provides an intensive pre-cleaning process. Light material is suspended in the wind stream, carried over the sieves and discharged out of the machine.
Turbine Fans
Each of the six turbine fans have their own air inlet. This prevents air starvation to the fans and provides a consistent blast of air to the sieves.
Wind Reduction Kit
Shutter plates are available, which reduce the air intake area of the turbine fans when harvesting light crops. These shutter plates are adjustable to restrict the air flow to suit crop conditions.
Counter Movement of Sieves
Upper and lower sieves operate in opposite directions resulting in smoother running and less wear and improved self-cleaning of sieves.
Sieve Adjustment
Top and bottom sieve openings can be controlled from the cab at the press of a button or the combine can make its own sieve setting based on the type of crop to be harvested.
3-D Sieve System
When working across slopes, the crop slides downhill on the sieves and the air flow takes the line of least resistance. Chaff and straw are no longer held in suspension and a mat of material begins to build up on the sieves, resulting in severe grain loss. Solution: The Cat 3-D slope compensation system.
3-D Cleaning
Working on level ground, the normal action of the 3-D sieve is to move backward and forward sorting grain from chaff.
Performance Monitoring
Monitoring output gives the operator the final check on grain loss from the sieves, rotors and walkers.
Returns Monitoring
Returns are distributed in front and across the full width of the accelerator and then undergo the full threshing and separation process again. It is easy to visually check the returns while harvesting.
Grain Elevator
The grain elevator is designed to move large volumes of grain to the tank. The elevator chain tension is adjusted by a conveniently positioned draw bolt.
Grain Tank
Large capacity. The operator is informed of the quantity of grain in the tank by both visual and audible warnings.
Clean Grain Auger
The grain tank filling auger floats on the rising crop and fills evenly from the middle of the tank.
Grain Tank Unloading
Grain tank unloading is operated by a switch on the multi-function control lever.
Checking Grain Quality
Caterpillar combines give you the best grain handling and quality monitoring systems available.
Serviceability
Hood
Hood opens completely for easy access to conveyor chains and snapping rollers.
Snapping Rollers
Rollers are front supported and equipped with four adjustable blades with tungsten inserts and a helicoidal ends for easier stalk insertion.
Rotary System
The rotary system is easily accessible for inspection and service.
Engine Compartment
The engine compartment is open and accessible, and side doors open wide.
Mobile Service Fleet
With more than 70 years of experience in providing the best possible support for customers, Caterpillar has built the most extensive mobile service fleet in the country.
Parts Availability
The parts distribution network works 24 hours a day to make sure that when you need a part, you'll get it - fast.
