1 ENGINES It s the Engine That Matters Mst Outdr pwer equipment lasts a lng time. Make sure yu chse the right equipment, and the right engine brand t pwer it. Mst cnsumers recgnize that the single mst critical cmpnent t cnsider n utdr pwer equipment is the engine. That s because Ease f starting, durability and available pwer directly impact pwer equipment perfrmance and yur satisfactin with it. When cnsidering the engine brand, keep in mind that sme engine manufacturers prvide a much brader engine lineup than thers. The brader the engine line, the mre chices yu have in terms f pwer, features and price levels n the equipment yu purchase. What t Cnsider When Selecting an Engine Easy starting features There are a variety f ways t make starting easier and they will vary by the engine yu select. T be sure yu find the cmbinatin f features and pwer that s right fr yu, lk fr an engine brand that ffers a wide selectin f easy-starting ptins.

2 Pwer Engine pwer is the single biggest difference frm ne piece f pwer equipment t the next. Fr instance, the mre cutting pwer a lawnmwer has the mre easily it will maintain the speed f the blade and deliver a cnsistent, quality cut, even under tugh cnditins. Lawnmwer cutting pwer is a cmbinatin f three things: Engine size In cmbinatin with engine cnfiguratin, engine size is the mst imprtant factr in a lawnmwer s ability t handle tugh, demanding jbs. The higher the trque r hrsepwer rating, the mre pwer the machine has t get the jb dne. Fr walk-behind mwers, Briggs & Strattn engine sizes typically range frm 4.50 t 8.75 grss trque. Fr riding mwers the sizes typically range frm 10.5 t 26.0 grss hrsepwer Trque is defined as the twisting frce that tends t cause rtatin. It is a mre direct way measure pwer in walk-behind mwers as well as pressure washers and generatrs. MORE TORQUE = BETTER CUT MORE TORQUE In walk-behind mwers, mre trque means a cleaner and mre even cut, even in high, thick grass. MORE TORQUE = BETTER CUT In pressure washers, mre trque means mre punds per square inch (PSI) and gallns per minute (GPM) f water fr imprved pressure and cleaning. In generatrs mre trque means higher wattage utput under full lad. Hrsepwer is the rate f ding wrk ver time. It is a mre meaningful measure f pwer fr riding lawnmwer engines. That s because pwer in ride engines is distributed t the transmissin, wheels, hydraulics, and the cutting blades via varius gear ratis. This makes hrsepwer a mre meaningful measure f the ride engine s ability t get the jb dne. CC s (cubic centimeters) is a measure f size and indicates an engine s vlume r capacity. Engine cnfiguratin Walk-behind lawnmwers are typically equipped with smaller side valve r Overhead Valve (OHV) engines. Side valve engines prvide exceptinal value and perfrmance at a variety f pwer levels. ºº Light-duty engine sizes range frm 4.50 t 5.50 ft-lbs f trque. ºº Mid- t heavy-duty engine sizes range frm 6.25 t 6.75 ft-lbs f trque.

Lawnmwer cutting pwer is a cmbinatin f three things: Engine size In cmbinatin with engine cnfiguratin, engine size is the mst imprtant factr in a lawnmwer s ability t handle tugh, demanding jbs.

3 OHV engines ffer significantly mre pwer, run smther and quieter, and are better fr the envirnment since they burn fuel mre efficiently. Direct Overhead Valve (DOV ) engine technlgy is als available. It has fewer mving parts, which further reduces engine size and vibratin. ºº Heavy-duty engine sizes range frm 7.00 t 8.75 ft-lbs f trque Riding lawnmwers are typically equipped with larger single-cylinder r V-Twin (tw cylinder) OHV engines. Large, single-cylinder engines cver a brad spectrum f pwer levels and range frm being designed fr value t being designed fr premium perfrmance and durability. V-Twin engines take perfrmance t the next level. They prvide greater hrsepwer and better balance that translates t lwer vibratin and greater cmfrt, and are quieter than single cylinder engines. And, they run cler and burn cleaner. Mwer cnfiguratin This is a matter f mwer deck size, features and design. Mwer cnfiguratin will determine the amunt f engine pwer needed t get the jb dne easier and faster. Push and side discharge walk-behind mwers with smaller decks will require the least amunt f pwer. Lk fr light-duty side valve engines in these cases. Rear bagger and self-prpelled mwers, and mwers with larger cutting widths, will require mre pwer. Lk fr larger OHV engines in these cases. Riding mwers with smaller decks and gear-driven transmissins typically require less pwer. Lk fr large single-cylinder engines in these cases. Riding mwers with larger decks and hydraulic drive trains demand mre pwer. Lk fr larger V-twin, OHV engines in these cases, and when the mwer will be used fr twing ther equipment. Hw and where will the equipment be used? In the case f lawnmwers, the size and terrain f yur yard will determine whether yu select a push r a self-prpelled walk-behind mwer r a riding mwer. The cnditin f yur yard and yur mwing habits can als make a difference in the engine yu select. Cnsider the fllwing cnditins when selecting an engine: Size f yard typically, the larger the yard, the higher the pwer needed. Heavy, thick grass r hilly terrain - lk fr higher trque r hrsepwer ratings. Frequent cutting; Large yards lk fr enhanced starting features like ReadyStart frm Briggs & Strattn, and easy access service pints fr air, fuel and il filters. Dirty, dusty areas; Extreme heat lk fr advanced air and fuel filtering and full-pressure lubricatin systems n engines fr riding mwers.

4 Durability and Perfrmance It is imprtant t select an engine manufacturer that has a lng histry f delivering durability and perfrmance. One that ffers an extensive lineup f engines that are engineered fr perfrmance n a budget and thse designed fr superir pwer and reliability, with features intended t make getting the jb dne easier and faster. Additinal engine features may be included as the price range increases n mwers. Here are sme engine step-ups t lk fr: Walk-behind mwer engines Higher trque ratings OHV r DOV design Easy starting features like ReadyStart frm Briggs & Strattn Autmtive-style air cleaner L-Tne muffler Riding mwer engines Higher hrsepwer ratings V-twin design Full-pressure lubricatin systems Premium air, il and fuel filters Advanced debris management systems Cast irn cylinder sleeves Chrme plated valves and super-finished bearing surfaces Serviceability Selecting an engine brand that is easy t maintain and service is key t yur prduct satisfactin: Sme easy maintenance features t lk fr are: Autmtive-style dipsticks Easy access service pints fr air and fuel filters Spin-n il filters Lk fr an engine brand that ffers: An extensive netwrk f dealers including certified master service dealers A full line f genuine replacement parts available at dealers and select retailers Extensive custmer supprt fr parts and an nline service center lcatr Online assistance with hw-t prjects, maintenance and service tips Electrnic maintenance reminders
