I'm considering going full time this coming year. I currnently have a 36 in. 14 HP kaw Snapper walk behind. Checked out the ExmarkHP 48 in. 21 Hp kaw last night. I will be mowing residential and hopefully some small commercial. Should I add a velkie to my Snapper(and double blade it) saving time over last year being able to mow in fifth gear or go for the Exmark which financially will knock me back. Should I wait until the business really takes off amd then go for the Exmark? I have 20 or 21 accounts from last year. Any feedback greatly appreciated! Thank you!
