SIX GOOD REASONSTO MAKE ITYOUR FIRST CHOICE.1collected debris can be flushed outduring normal maintenance.Plenty of power,plus economy.Choose either the 18-hp OMC air-cooled engine or the 4-cyclewater-cooled diesel. Both deliver thepower and performance you need.The Front Line mower is designedfrom the engine up, not from thetractor down, so every workingcomponent complements thepower plant.2Fast, maneuverable,simple operation.Hydrostatic drive and wheeltype steering make operation easy.Single rear turning wheel, and splitfront-wheel traction-assist pedals allow smooth, zero-turning radius; thedriver's hands stay on the wheel.Mechanical clutch direct-drivePTO gives you a powerful tractorthat's built to take it.3The cleanestof cuts.The three heat-treated bladeswith air-lifts along with the Cushmandeck and baffle design cut the grasscleanly. Clippings are lifted up anddischarged out the chute evenly,eliminating the blade drag that eatsup power. Choose a 60" or 72" deck;both offer top-mounted grease fittings and covers that remove withjust two wing nuts.The 72" deckalso corres withwash-outholes so4No scalping.5Year-roundversatility.Rear deck rollers work alongwith the front wheels to keep the deckand blades off the ground, even overrough terrain. Springs are alsoavailable to absorb deck weight andallow the deck to "float" withthe contour of the ground. (Theseanti-scalp packages are optional,depending on the contours of yourparticular turf.)The Cushman Front Linedoesn't go out of service when themowing season is over. It can workfor you all year 'round when you addaccessories like the ROPS structureand weathertite cab, 60" rotarybroom (gas unit only) and the 48"snow thrower.6Servicewhen you need It.Your Cushman Front Linedealer stocks parts for the engines,tractors and decks, and services theentire unit.

ANNIVERSARYfrom page 30SPRAYER WAS JOHN DEERE'S FIRST LANDSCAPE PRODUCTTwo generations of John Deeremodel of the 14-hp 214 Tractor.lawn and garden tractors, the 1964 model of the 8-hp 110 Tractor (right) and the 1981John Deere entered the landscapebusiness in 1962, the same year thatWeeds, Trees 8r Turf began publishing. The first John Deere landscape product was the No. 5 Lawnand Garden Sprayer. In 1963, JohnDeere built its first lawn and garden tractor, a 7 hp model 110 withsuch attachments as a centermounted mower, snow throwerand front blade. The 110 provided athree speed trans-axle with a special feature: variable speed drivevaried ratios on a belt and pulleysystem to allow the operator to slowdown or speed up any gear withoutclutching and shifting. The tractorwas available only through JohnDeere agricultural equipment dealers in the eastern part of the UnitedStates in 1963. An 8-hp 4-speed version of the tractor was sold throughmost John Deere agricultural dealers in the United States and Canada in 1964. T h e tractor wasmanufactured at the John DeereHoricon Works inHoricon,Wisconsin.During the early 1960's, theHoricon Works became the world'slargest producer of agriculturalgrain drills (mechanical seeders).But, because grain drill sales weresubject to seasonal fluctuations, theJohn Deere organization sought aproduct line that would help thefactory use its facilities moreuniformly.Gary Lindquist, division manager, grounds care at the Horiconworks, explained why John Deereentered the outdoor power equipment business. "We had several research studies done for us on thelawn care business in the early1960's. At that time, there appearedto be good potential for growth inthis market. The research also determined that lawn care productswould provide additional sales forJohn Deere agricultural equipmentdealers. We found that the JohnDeere reputation for building highquality farm tractors and implements would help our CP (consumer products) business in ruralareas, providing a strong springboard to sales in suburban areas.One of our early goals was to develop independent CP dealershipsto help us penetrate the suburban,nonfarm market. It remains an important objective for our organization."In 1966 John Deere added a 6-hp60 Lawn Tractor and a 10-hp 112Lawn and Garden Tractor. JohnDeere produced a 14-hp 140 Hy-drostatic Tractor in 1967.John Deere introduced a newutility tractor in 1968. The 820 Tractor was powered by a 3-cylinderdiesel engine producing 31 hp atthe PTO. It was manufactured at aJohn Deere factory in Mannheim,West Germany, and marketed inNorth America through the JohnDeere Tractor Works in Waterloo,IA.During 1969, John Deere's Horicon Works experimented with custom colors, providing some lawnand garden tractors with seats andhoods of orange, red, yellow andblue—instead of the traditionalgreen hood with yellow seat andwheels. It was soon found that customers preferred the green and yellow combination. "Once you establish a good reputation, your colorscome to represent that reputation,"said Lindquist.Another significant event occurred in 1969. The Horicon lawncare equipment business hadgrown to such an extent that theproduction of grain drills wastransferred to a John Deere factoryin Iowa. The Horicon Works begandevoting all its time and energy tothe development of consumerproducts.
In 1970 John Deere replaced its60 Lawn Tractor with a 7-hp 70Lawn Tractor, and expanded thelawn care line to include six models of walk-behind rotary mowers,two riding mowers, lawn sweepersand a 12-hp 120 Hydrostatic Tractor. Walk-behind tillers and snowblowers joined the line in 1971.From 1972 to 1974, John Deereadded an electric-powered ridingmower, dumpcarts, and gasolinepowered edger-trimmers.The 820 Utility Tractor was replaced in 1973 by a more powerfulMannheim-built tractor—the 830developed 35 hp at the PTO. It waspowered by a 3-cylinder diesel engine and featured an 8-speed transmission with 2-lever control andbuilt-in shuttle shift.1974 was a pivotal year for JohnDeere. The company introducedwhat it termed the "second generation" of lawn and garden tractors,lawn tractors and riding mowersfor sale in 1975. "We put side panels on the tractors and enclosed theengines for quiet operation," according to Lindquist. "We styledthe tractors so they would have afamily resemblance to John Deerefarm tractors, a feature that wethought would appeal to both ruraland suburban customers. We werethe first manufacturer to offer acomplete line of quiet lawn andgarden tractors and riding mowers."On January 12,1977, the HoriconWorks celebrated a milestone bymanufacturing its half-millionthtractor. The event pointed up thedramatic progress the factory hadmade in only 15 years. Factoryplant area had increased by 81 percent, and average yearly employment had more than doubled.John Deere added compact utility diesel tractors to its grounds careline in 1978. The 22-PTO-hp 850and the 2 7 - P T O - h p 950 are marketed through the John DeereTractor Works in Waterloo. Bothtractors are powered by 3-cylinderdiesel engines. A 33-PTO-hp 1050Tractor joined the line in 1979.The 1050 is powered by a turbocharged 3-cylinder diesel engine.An M F W D (mechanical frontwheel drive) option gives the 1050positive traction in mud, slush andsnow. The MFWD option was extended to the 950 as well.In 1981 John Deere added twomore compact utility diesel trac-tors: the 14.5-PTO-hp 650 with a2-cylinder diesel engine, and the18-PTO-hp 750 with a 3-cylinderdiesel engine. Johnny A. Dickinson, division manager, utility tractors at the Waterloo factory, said,"These new diesel tractors are designed to fill the gap between JohnDeere gasoline-powered lawn andgarden tractors and our higherhorsepower diesel tractors. Our research shows that prospects require a greater range of forwardspeeds than is now available inmany competitive tractors. Theywant ample ground clearance, acompact size for storage in a utilityshed, a more convenient implement attaching system, and theavailability of a full line of implements. Our compact utility dieseltractors meet these objectives."The lawn tractor business hasbeen a significant growth area forthe John Deere consumer productsorganization. From 1977 to 1981, theannual production at the HoriconWorks has increased by 1041 percent.The most recent addition to theJohn Deere compact utility tractorline is the 1250—a 40-PTO-hp diesel tractor.ANNIVERSARYMcDonald notes with pride the18-hp OMC engine's legacy of durability and performance. Whilemajor automakers were constantlybuilding bigger blocks, OMC Lincoln decided to make its enginesimply better with ongoing refinements of the same standard design.The '60s rolled out and the '70s inwith the unveiling of a 4-wheeledtruckster. The Lobster lost its nichein the product line, however, just asthe Cushman Eagle motorscooterdid in 1965. The demand simplywasn't there, so O M C Lincolnfocused its product emphasis elsewhere.The year 1973 reflects that fact.OMC Lincoln was heralded thenfor introducing its quick-change,pin-disconnect system on Turfcare units. The ability to promptlyswap utility beds and accessoriessaved manhours and lended newflexibility in a vehicle having consolidated roles. That year the firmalso introduced its Runabout vehi-cle which has become a mainstay inits turf industry marketing."That one feature placed us sofar ahead of the competition thatwe didn't undertake another majorrefinement until 1978," McDonaldnotes. "That year, however, we introduced our radial frame on theRunabout and added a Greensaveraerator attachment to those accessories already established. T h eTurf Minute-Miser went the way ofthe Lobster. In 1979, we began marketing a 2-seat Runabout and thefollowing year a power converter toaccommodate the growing numberof electric tools used out on thecourse."The Turfcart model followed ayear later, providing the industrywith a low-cost transport for minorchores. Cushman begins 1982 witha totally redesigned model line."The industry is unique so wewill continue listening to what itneeds and reacting accordingly,"McDonald predicts. "We intend tomaintain our role as a bellwether."from page 30full model line.The 1967 models were dedicateddesigns for turf care. There was an18-hp Turf-Truckster vehicle having a pickup-style bed, an 8-hp unitwith the same feature and one having a stripped chassis. A unit oddlyenough named the Lobster had an8-hp engine, along with a sister unitpowered by a 5-hp engine to provide personnel transports.Always sensitive to the user,OMC Lincoln entered the 1968 season with a 12-hp Turf-Trucksterand beefed up the 5-hp MinuteMiser vehicle with a 6-hp engine. Anew sprayer having rear boom delivery operated by the vehicle PTOemerged as another innovation.T h e 1969 season evolved intoTruckster vehicles powered by18-hp, air-cooled engines equipped with pickup beds, wide-boxdumpbeds and a 12-hp pickup anddumpbed were other options.
