Being a USA web site it is only in English
The drive belt is very high to keep it out of harms way between the frame rails.
Go to the back, put your hand under the mower and feel on top of the rear axel and you will feel the drive pulley & belt.
The cut height on that model is set by the dial below the seat, behind your legs.
with the deck lever in the off position ( closer to you ) turn the dial to change the height then when you move the lever forward it will allow the deck to go further down, with some of them the lever also moves further with lower cuts.
Garden Way no longer exists and neither does Bolens
There should be a tag under the bonnet in the side of the mower with the model numbers and the engine should have it's model numbers stamped into one of the rocker covers.
When sending queries to this list please use these numbers to identify your engine & mower.
