1.2 Principles of sharpening

The reel type lawn mower cuts grass using theprinciplesofshears. It isnecessary, therefore, tohavetwosharpcuttingedgesmakingcloseenoughcontacttocutthegrasscleanly.Thisistheleastharmfulmethodofmowinggrass,becauseeachbladeofgrassissupportedbythebedknifewhilethereelbladeshears itoff.

The bed knife, therefore, is themaster cutting element and although made of heavierandhardersteels,it isimpossibletoproperlysharpenamowerwithdull reelbladeswithoutsharpening thebedknifetoo.

2. Installation and Set Up

2.0 Locating the grinder

Determine where on a concrete slabthegrinderwillbelocated.Thereelmountsontop.Theoperator loadsandworksfromthe front.Adequate working area must beprovidedaroundthereelgrinder.

The Peerless requires standard 110volt,60Hz,singlephaseservice. Foreignversions with 200 volt, 50/60 Hz, singlephaseareavailable.Thegrindercomeswithan8footgroundedcordfor110voltservice.Thegrinderalsorequiresabout70psicleancompressedair.

2.1 Unpacking the grinder

Whileunpacking,examinecarefully foranyshippingdamage.Anydamageshouldbereportedimmediatelytothecarrier.

By now you have removed the plasticwrap from the main crate. After removingthe box of accessories and any otheroptionalequipment,unboltthegrinderfromthe pallet and place it in the location youhaveselected.

3. Preparing to Grind

3.0 Preparing the reel mower for grinding

Clean all dirt, grass, rust, grease, andoil from the mower assembly, especiallywhere it accumulates behind the lip of thebedknife.

Inspect for a wavy appearance orconditionalongthetopfaceofthebedknife.This would indicate that the bed knife hasbeen adjusted to the reel with excessivepressure. This could causewornor loosereelbearings.

Page 13: Peerless™ 3000 & 4000 Operating Manual

Checkthatthefrontspacerbarandthatthe bed knife is not loose. If the frame isloose,itisprobablyoutofalignment.Checkthemowermanufacturer’smanual to resetalignment.

Check the reel for free rotation andexamine the reel blades forbadnicks thatmightindicateatwistorsprungspider.

Check to see that reel blades aresecurelyfastenedtothespidersandthatthespidersaresecureonthereelshaft.Repairasnecessary.

Checkforaxialandradialplayinthereelbearings. Adjust or replace the bearingsin accordance with the manufacturer’smanual.

Ifyouaregrindingwiththebedknifeinplace, locate the reel so that the grindingwheel will only grind the reel blades andclears the bed knife, front roller, and anyother part of the reel. If you are going torelief grind, you will need to leave enoughclearance between the reel blade and thebedknifeforthereliefgrindingmechanism.
