Commercial mowers are exactly what they sound, mowers for commercial use, and typically used by lawn service companies. These mowers are built for regular use and are built to withstand this heavy use. They have higher quality engines than that of a residential mower and they have higher horsepower. These mowers are typically for larger terrain like that of a golf course, or they are meant for difficult terrain like hilly yards. Homeowners typically use residential mowers that are built for about an hour of use no more than two hours a week; however, if you find yourself spending more time than this on your lawn it is recommended you consider purchasing a commercial mower, despite the higher cost. With that, you may just want a professional looking lawn and commercial mowers will get you there.
In terms of repair, we repair commercial zero turn gas run (no diesel) mowers with no hydraulic components, like buckets or lifting equipment.
If your commercial mower won’t start, is difficult to start or runs inefficiently, it is probably due to the fuel or gas. First check to see if the quality of your fuel is up to par for your machine. Most commercial mowers need E-10 rated (10% ethanol) fuel. If the ethanol levels are too high your engine can prematurely fail. It is also important to consider how long the fuel has been sitting. If your fuel has been sitting for awhile, it is time to empty it out and replace it.
If none of this gets her running, it may be time to clean the carburetor. First try a canned carburetor cleaner, but if that does not work you may need to manually clean it.
If your mower is having electrical issues, first check for any blown fuses and replace them if necessary. Also check the batteries for appropriate power. These mowers should be running on a minimum of 12 volts. While looking at the battery power, check for loose or corroded batteries, tighten the clamps and clean terminals if necessary as well.
Next, look for loose, corroded electrical connections. Make sure to check for frayed or broken wires as frayed wires are a danger and it won’t deliver the correct amount of power.
Lastly, check all the spark plugs and replace them if necessary.
Low Cut Quality
If the overall cut job is low quality, clean the cutting deck. Blades of grass will cake onto the deck and harden causing a low quality cut. Make sure to also clean the top side of the deck as well.
First check the tire pressure. Make sure all of your tires are filled to the recommended amount. Next, measure the blades on an even surface and adjust the deck shell accordingly. You want the blades to be placed where it is recommended, and you want the blades to be even to one another.
If your cut is inconsistent or spotty, your may have dull bent or broken blades. Check your blades because it may be time to sharpen them or even replace them. Also, make sure to check the RPMs. Low RPMs will affect the cut quality.
Tips for Regular Maintenance
- Wash often and as necessary. While cleaning make sure to cover all electrical components to avoid damage. When you finish washing your mower make sure to dry with a towel and if you see fit, use a leaf blower to dry areas that are tough to reach with a towel.
- Make sure to store it away from the sun and weather. Sun can cause premature damage to the mower, and weather can cause the mower to rust.
- Also remember to check the oil daily and while checking the oil inspect the whole machine for loose bolts. However, it is very important to check the oil because if you run your mower with low oil or bad oil you can cause serious damage.
- Clean the underside of the mower deck. As previously stated, debris and grass blades will accumulate and cake on to the deck hardening. To avoid any issues related to dirty mower decks, make it a habit to clean daily.
- Make it a habit to sharpen your blades about 3 times a year.
- Check your tire pressure because again, low tire pressure can result in an uneven cut.
- Lastly, check the RPMs because again, if you are running your mower on low RPMs your cut will be inconsistent and will result in low quality cut. To avoid this, check the RPMs to make sure it is running where it needs to be.
