Allis Chalmers Adds Four New Tractors
![]() |
If you haven't yet talked to him since he got back, here's fair warning to be prepared - he's got a lot to talk about, including four new tractors ranging from 21 to 300 engine hp.
Model 8550: Boasting 300 engine hp (250 PTO hp), this articulated 4-wheel drive diesel becomes A-C's "top of the line" tractor. It's powered by a model 6120 T company-built inline 6 cyl. diesel. The engine has a displacement of 731 cu. in. operating at 2500 rpm rated speed, and features a "two head design" and dual turbo chargers with twin exhaust pipes.
Be sure to ask your local A-C dealer about the new 8550's exclusive 20 speed Power Director transmission. He'll tell you it offers "more forward speeds with on-the-go shift capability than any competitive tractor". A fully independent 1000 rpm PTO, with a 1-314 in. shaft, is standard.
Other features include a draft sensitive, 3-pt. hitch (Cat. III or IV) with quick coupler and drawbar, 75 gpm hydraulic system, new-style Acousta cab, luxury swivel seat with 10 different comfort adjustments, 170 gal. fuel tank and power shift or nonpower shift wheels available with single or dual options. Duals can be axle mounted or clamp-on in sizes ranging from 18.4 to 30.5.
Model 7045: Rated at 145 PTO hp, it's the "big brother" of another new tractor, the model 7020 at 123 pto hp. Together, they fill out the company's line of "over 100 hp" two-wheel drive tractors.
It's powered by a 426 cu. in. turbocharged, in-line 6 cyl, A-C model 670 diesel engine and is available with two transmissions - a 20 speed Power Director, and a 12 speed power shift. The Power Director provides "on-the-go" shifting between high and low ranges for maximum performance and fuel efficiency. It has 12 speed selections below 10 mph, with 8 of those in the most used working range of 2.5 to 6.5 mph.
The new tractor is equipped with fully independent 54011000 rpm PTO speeds, built with a reversible onepiece drive. The new Acousta cab II is standard equipment, and is a refinement of the Acousta cab which holds the distinction of being one of the quietest tractor cabs built.
Model 7020: Its power plant is a 301 cu. in. in-line 6 cyl. A-C model 649 turbocharged and intercooled diesel engine with a rated speed of 2300 rpm. Other key features include 16 or 20 forward speeds with shift on-the-go between high and low ranges, or an optional 12 speed power shift transmission. Nine of 12 speeds in the optional power shift transmission are under 10 mph in the most used working range. The power shift is specially designed to always allow one clutch pack to remain engaged while one is dropped and another added. "This feature is extremely effective in providing shock free shifting on-the-go," your local A-C; dealer will tell you. It's equipped with fully independent dual 54011000 rpm PTO speeds, a traction booster system, Cat. III or IV 3-pt. hitch and up to three remote outlets. The new Acousta II cab is standard, and the new tractor's 51 gal. fuel tank fills from ground level.
Model 5020: The first of two low horsepower tractors introduced by A-C, it's built in Japan and is powered by a 21 hp Toyosha 77 cu. in. 6 cyl. diesel engine. It has an 8-speed transmission with 2 speeds in reverse. Its PTO runs at 540 rpm. Front
axle has a clearance of 12.5 in. Wheelbase is 59.8 in. Comes with hydraulic system and complete line of tailor-made plows, discs, cultivators, mowers and other attachments.
For more details oh these new A-C tractors, see your local dealer or contact: FARM SHOW Followup, Allis Chalmers Corp., Box 512, Milwaukee, Wis. 53201 (ph. 414475-4270).
