When I tell people that I'm the landscaper who looks after our team's football field they are really impressed, and a little jealous. I don't think they know how much work it is though - it's definitely trickier than keeping your backyard looking green. Not only does my football field need to look lush, it also needs to be perfectly even so that the ball doesn't bounce at crazy angles, and not so soft that the players boots sink in. I need to keep up with all of the latest tricks that landscapers have, and I write these up here so that everyone can give them a try on their own fields.
When it comes to the type of mower you use on your property, you don't want to choose a model based on the cost alone. An underpowered mower can mean more maintenance costs down the road, as you may wind up replacing worn parts or the entire mower itself more often than if you invested in a heavy-duty mower. Note a few hints that it may be time to upgrade to a heavy-duty, commercial mower for your residential property, and how it can make lawn upkeep easier overall.
If the grass you cut is often wet, this can cause quite a bit of wear and tear on the mower. Wet grass means heavy grass and clippings that cling to the blades and underside of the mower; this dulls those blades and also causes drag on the mower, and it clogs the chute where clippings should be dispelled. Not only will you need to clean the underside of the mower more often when you cut wet grass, but this can also mean having to sharpen the blades and replace the motor more often as well. A heavy-duty mower can more easily cut through wet grass and won't suffer the same wear and tear as a lightweight mower.
Even if you don't get tired from walking behind a mower to cut a very large lawn, note that a lawnmower may not be made to work uninterrupted for an hour or several hours. The motor of a lawnmower may not have the same cooling features as your car engine, and the heat it builds up can be very damaging to all the moving parts under the mower; it can even burn the oil and cause it to degrade. Upgrading to a commercial mower will often mean less overheating so that the mower lasts longer over time.
Weeds and brush
A lightweight mower may be able to cut through thick weeds and brush if you push down on the cutting deck and repeatedly go back and forth over that area, but as with cutting wet grass, this usually just means more wear and tear on the motor, bearings, blades, and all other parts of the mower. This will also mean dulling the blades so they need sharpening more often. If your property has lots of weeds and brush and you're not cutting just soft, fine grass, it's time to upgrade to a heavy-duty commercial mower.
