Mowing Pattern & Tips For the first use of the mower choose a smooth level area. Cut long straight strips overlapping slightly. The size and type of area to be mowed determines the best mowing pattern to use. Obstructions such as trees, fences and buildings must also be considered. Where possible, make one or two passes in a clockwise direction around the outside of the area to keep the cut grass off fences and walks.
A IMowing Patterns & Tips MULCHING MOWER OPERAnON (Optional Attachment) Mulching Mulching consists of actually cutting and recutting clippings into tiny particles and blowing them into the lawn. These tiny particles decompose rapidly into by-products your lawn can use. Under proper conditions, your mulching mower will virtually eliminate noticeable clippings on the lawn surface. Keep in mind these mulching tips: a. Use mulching mower or mulcher kit without shredders for grass mulching. b.
b. Avoid mulching after rain or heavy dew. It may be better to mow later in the day or early evening when lawn is drier. c. Change the mowing pattern each time. d. If mulching baffles are removed, the original deflector must be in operating position for safe side-discharge mowing. How Much Grass To Cut CM Removing too much grass height in one cutting may result in an unsatisfactory cut: windrowing, clumping, or uneven dispersal of clippings may result.
Normal Care SCHEDULE - The following schedule should be followed for normal care of your tractor and mower. You will need to keep a record of your operating time. Determining operating time is easily accomplished if the tractor is equipped with an optional hourmeter. If not, multiply the time it takes to do one job by the number of times you’ve done the job. (hydro model, Mfg. *See the engine manufacturer’s owner’s manual. *Change original engine oil after first 5 hours of operation.
Normal Care RAISING THE HOOD &SEAT DECK 1. To raise the hood, grasp both sides of the hood (A, figure 14) near the dash and pull outward. Pivot the hood up and forward. 2.To open the seat deck, pull down the latch (8, figure 14) located ahead of the left rear wheel, and tilt seat deck back. CHECKING/ADDING GASOLINE A CAUTION Never use gasoline containing METHANOL, gasohol containing more than 10% ethanol, gasoline additives, premium gasoline, or white gas because engine/fuel system damage could result.
Normal Care CHECKING FUEL FILTER A WARNING Do not remove fuel filter when engine is hot, as spilled gasoline may ignite. Do Not spread hose clamps further than necessary. Ensure clamps grip hoses firmly over filter afler installation. The fuel filter is located in fuel line between fuel tank and carburetor. If filter is dirty or clogged, replace as follows. Place a container below filter to catch spilled gasoline. 1. Using a pliers, open and slide hose clamps from fuel filter. 2. Remove hoses from filter.
