Important:
Maintain pressure in all tires to
ensure a good quality-of-cut and proper machine
performance.
Do not underinflate the tires.
Important:
Traction performance, including
tire-slip control, is dependent on the ratio of the
tire size between the front and rear tires. Use only
genuine Toro tires.
