Which mower is best for a middle-aged person to use on hilly terrain (a lot of slanted ground also) ? Does the JS48 require a lot more maintenance than the JS38? My very old Briggs and Stratton engine is dying and it is 6 hp. Not sure if the 7.25 ft torque on the JS38 is as powerful as the 6.0 hp or do I need the 8.75 ft torque of the JS48? Appreciate any help on this. Thank you. :smile:
