These ConExpo articles were published in Construction Equipment Guide (CEG) on March 5, 1975 and June 25, 1975, respectively. These and other ConExpo articles to follow will be part of a continuing series that take a look back at ConExpos past through the reporting of CEG. We hope you enjoy these retros as much as we did searching for them deep in our archives.

Crawler loaders and dozers made their imprint on ConExpo.

Fiat-Allis

Fiat-Allis introduced five new crawler tractors and loaders to their line. The largest of the new ones is the FL-14-B loader with up to 143 hp and a 2.5 cu. yd. bucket. Next in size was the FL-10, which has a 110 flywheel hp and 1-7/8 yd. bucket, its dozer counterpart, the 10-B also was introduced and is going to be available with two blades and a ripper. A medium capacity loader the FL-9, features a break out force of 18,750 lbs., and a 1-5/8 yd. bucket. The final addition to the line was the “8” an 87 hp machine with an angle dozer.

John Deere

John Deere made a giant move into the big earthmoving equipment field with the introduction of nine new machines. These included two dozers and two loaders. The John Deere 750 dozer features a 110 hp engine and the new dual-path hydrostatic drive. Next step up in size is the 850 dozer with 140 hp and a 123-in. blade with hydrostatic tilt. The two new crawler loaders include the John Deere 755 with 110 hp and the John Deere 855 with 175 hp.

All feature the “dual-path” hydrostatic drive system that automatically selects the optimum speed and the power ratio to fit the job.

Massey-Ferguson

Massey-Ferguson introduced three new crawlers, the MF-600C loader, MF-D600C and the MF-D700C dozers. The new loader has a 2.4 cu. yd. bucket and variable pitch torque converter. The two dozers are 144 and 180 hp, respectively. The 700C weighs in at 41,000 lbs. Both feature planetary gear reduct to absorb operating shock.

Caterpillar

Caterpillar’s advances included the 200FWHP D-7G, a 300FWHP D-8K, and a 410FWHP D-9H. Other models included the D-6C LGP and the D-3 tractor. The D-7G, the D-8K and the D-9H feature complete steering control from the hand levers, which now combine the steering clutch, disengagement and braking. The D-6C can work in soft boggy material where wheels and standard tracks can’t go. The D-3 is the smallest Cat tractor designed for tight quarter maneuvering.

International Harvester

International Harvester’s PayLine division used ConExpo to welcome its newest crawler, the TD-20E pay dozer, a 210FWHP machine features simplicity in design and DVT-800 diesel engine. Another 25 more hp units were added to the TD-25C pay dozer, upping its rating to 310 making it one of the heaviest in its class.

Terex

Terex exhibited the new family of crawler tractors at the show. All three machines, the 82-20, 82-30B and the 82-50 maintain the same family appearance with major components and service points in similar locations. Horsepower ranges from 180 in the smallest to 370 in the largest of the new machines. All three feature a power train that is 100 percent General Motors.

Case

In addition to a new color, Case unveiled their new 1450 crawler loader. A 2¼ cu. yd. high productive unit, the 1450 is the largest crawler loader in the Case line.
