Self-propelled to me means 21's. If you have more than 20 lawns (which apparently you do) then I would suggest trading in those 21's for at least a 32" WB, the time saved itself will make up for any costs. Another consideration is maint. sure you have the sears "maint program" have you seen the people they hire to do their "maint" if they do it in house (most of the time they send it out - without giving you a loaner) Anyway imagine the reduction in maint costs for 2 32" WB's vs. 4 21's |
