SAFETY RULES • Follow the manufacturer’s recommendations for wheel weights or counterweights to improve stability. • Use extra care with grass catchers or other attachments. These can change the stability of the machine. • Keep all movement on the slopes slow and gradual. Do not make sudden changes in speed or direction. • Avoid starting or stopping on a slope. If tires lose traction, disengage the blades and proceed slowly straight down the slope.
SAFETY RULES • Remove obstacles such as rocks, tree limbs, etc. • Watch for holes, ruts, or bumps. Uneven terrain could overturn the machine. Tall grass can hide obstacles. • Use slow speed. Choose a low gear so that you will not have to stop or shift while on the slope. • Avoid starting or stopping on a slope.

• The average lawn should be cut to approximately 2-1/2 inches during the cool season and to over 3 inches during hot months. For healthier and better looking lawns, mow often and after moderate growth. • For best cutting performance, grass over 6 inches in height should be mowed twice. Make the first cut relatively high; the second to desired height.
BEFORE STARTING THE ENGINE • To restart movement, slowly release parking brake and clutch/brake pedal. • Slowly move motion control lever to slowest setting. • Make all turns slowly. CHECK ENGINE OIL LEVEL The engine in your tractor has been shipped, from the factory, already filled with summer weight oil. 1. Check engine oil with tractor on level ground. 2.
