I have 28 weekly lawns with the largest being .75 acres. I am currently using a toro proline 36" with a velkey which is starting to use some oil. Planned on buying a Gravely 34Z to replace my walk behind. If I had the 34Z I could get in all of my gates with one mower. If I had the 44Z I could get in about half of the back yards and use the toro and a 21" on rest. Will it be a wash on time or will the extra 10" make it worth the money. Thanks for reading.
