I'm new to the business. I have 3 mowers, 52", 36" and 21". Most of my lawns are small and about 1/3 have fenced yards. I have been trying to use my 36" more often but it seems like it takes more time and effort. It's a belt drive. Most of the professionals on this site seem to think the 36" is a good mower for getting through gates. That's why I bought it. But today I just used my 21" and things seemed easier. Maybe I just need more practice with the 36".
