Let off the pedal and give it more throttle and it will go faster up the hill.
My poor little abused lawn tractor always is at full throttle! I'll have to experiment is less pedal helps. I've always attacked the hill full throttle, full pedal & running start. Never tried less pedal. The firewood trailer is so heavy sometimes halfway up my dry paved driveway the tire just looses traction and starts to spin. I've added a lot of lead to my lawn tractor for tractor and it helps, but I really want this heavier tractor with 4WD! Hopefully before I destroy this poor little lawn tractor. The 1526 is too big for mowing my lawn, the lawn tractor is perfect for that. Plus a mid mower deck for the 1526 is serious money!
