I just went to see a client today, yes Sunday ! He actually had a legitimate complaint. His back yard was stripped with browned and green lines. Never saw anything like it before ! The yard is in full Sun. The only thing I could think of is that the tires got soo Hot they burned the grass as I mowed. Anyone have any Ideas or am I right ? ? What should I do to fix it ?? or should I ??? Can it be prevented in the future ?? His whole lawn is weak and I mentioned to him the heat and dryness and he informed me that he waters the lawn for 4 to 5 hours a day ?? Think that may be related ?? Thanks in advance...
