Careful consideration is required to preference between manual or automated grass disposal.
Lifting and carrying catchers is no easy task, especially when they’re full of wet grass. The less regularly you mow the faster your catcher will fill; which can turn mowing the lawns into a longer chore. Emptying catchers can substantially add to the time and effort of the overall mow, especially if you aren’t able to mow regularly.
Some mowers offer grass disposal from the seat, which can be either manual, electric, or hydraulic. Although this is an extra feature which you’ll pay more for up front, the convenience means you don’t need to get off the mower every time the bin fills. This is better in the long-term and makes mowing will be less arduous overall.
Your budget, available time and physical capacity will determine which option is best for you.
