BEFORE STARTING TRACTOR

Before you begin your workday, make a few quick checks to be sure your tractor and implements are in good operating condition.

⇒ Walk around machine, check for loose, broken, missing, or damage parts. Have everything put in good repair.
⇒ Make certain all safety devices are in place.
⇒ Check tractor & implement for leaks.
⇒ Make certain tractor and attachments are properly installed. Be sure the tractor & implement PTO RPM rating match.
⇒ If your tractor has a manual transmission and attaching an implement that require run off the PTO, you MUST have an over-run clutch (slip clutch). Note: Tractor should be park on level surface.
⇒ Check transmission-hydraulic system oil level to make sure the transmission oil is up to the required level by using the dipstick or check bolt. Note: Tractor should be park on level surface.
⇒ Check front axle oil level (4WD model only).
⇒ Check coolant level (Antifreeze). Add more if required. Make certain there is no leak, coolant system & radiator cap must hold 12 lbs or more. (If there is a leak in the coolant system, it will cause serious damage or over heat to the engine.)
⇒ Check Fuel level.
⇒ Check air intake connections to make sure there is no leak.
⇒ Check the tires for cuts, bulges and correct pressure.

STARTING ENGINE

⇒ NEVER start engine while standing on ground.
⇒ Check fuel shut-off valve.
⇒ Place power shift lever, range shift lever in neutral position.
⇒ Place PTO shift lever in neutral position.
⇒ Place hydraulic control lever in lower position.
⇒ Push or pull throttle lever to the maximum speed position. As soon as engine starts, push or pull throttle about halfway or little less halfway back. DO NOT RUN A COLD ENGINE AT FULL THROTTLE.
⇒ Do not operate starter more than 10 seconds at a time. If engine does not start, wait at least one minute before trying again.
⇒ Check indicator lamps as soon as engine starts. If lamps do not go out, stop the engine and determine the cause.
⇒ Operate engine at approximately 1500 rpm for five minutes. Do not accelerate or apply a load until engine warm up.
⇒ During the cold weather. Do not use starting fluid (Ether) in the engine.
