hello triper i had a nieghbor across from my farm. his front yard was almost stright up and down.this is how he did it .he got a pair of golf shoes with sprikes on soles then he got a 2 cycle lawnboy push mower and a long rope. he tied the rope to the handle bar with mower runing he would lower mower over from top then pull it back up and down untill done worked very well the reason for 2 cycle mower was it would not run out of oil. from chips papaw
