How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

What is the gas to oil ratio for Mantis 2-cycle engines? Always make sure you use the proper 50:1 mixture ratio; that is 2.6 ounces of oil to 1 gallon of 89 octane or higher gasoline. If your engine is getting hot, you may not have enough oil in your gas mixture to properly lubricate the engine.
If there is no spark, this indicates that the spark plug is defective and should be replaced.
The Mantis 4-cycle 7268 starts easily, runs quiet, and requires no gas/oil mixture in the tank. Honda® 4-cycle engine.
You could have a clogged fuel cap, which can prevent air from entering the gas tank. Loosen the gas cap a little and start the tiller again. If it starts and stays running, try cleaning or replacing the gas cap. A clogged carburetor could also be the problem.
Features a powerful 2-cycle engine (requires gas/oil mix) with push-button priming for easy starts.
Fueling your tiller is easy. Unscrew the gas cap and fill the tank about four-fifths of the way with 89 octane unleaded gasoline. Remember to always drain the gas when transporting the unit from one location to another. CLOSED CHOKE LEVER • Press the primer bulb approximately 6 times until he bulb is filled with gas.
The plug will depend on the SV number on your engine; the gap will be the same for each engine – . 024-. 028.
The main reason that your cultivator would idle, but then die at full throttle, is not enough air entering the engine. The carburetor would be a good place to look first, as its function is to ensure the proper ratio of air and fuel enters the engine during combustion.
Your tiller is only compatible with 86 octane gasoline, which should never have an ethanol level over 10%. Using anything other than the correct fuel can cause irreparable damage. During the winter months, you should drain the fuel tank, then run your tiller until there is no fuel left in the system.
The Mantis brand is one of three brands within the Schiller Grounds Care brand family. Located in Southampton, Pennsylvania, Schiller Grounds Care also produces Classen turf care equipment and Little Wonder debris management equipment.
If the rotary tiller still doesn`t start:

Check that the fuel tank isn`t empty: if necessary, add fuel. The fuel must be fresh, of good quality and clean: make sure that no dirt, water or incompatible fuel (such as petrol-oil mixture, if the engine is a 4-stroke) gets into the tank.

Check the Fuel Filter

To start, tap the side of the carburetor to help the flow of gas. If that doesn`t work, you might have a clogged filter. Not all lawn mowers have a fuel filter, but for the ones that do, it`s usually located in the fuel line or the fuel tank.

The model number on a Mantis tiller can be found on a white label, located on top of the engine housing. The model number will be located at the bottom of the label in the “Item#” field. Enter the model number of your Mantis below to search for parts.
A 2-cycle engine has one fill port with a cap that has fuel pump and oil can icon. The cap will usually state the oil to fuel mix ratio. A 4-cycle engine has two fill ports with each cap separately identifying the fuel tank from the oil sump.
Since only two strokes are required to produce power, the 2 Cycle engine has less work to do and so has greater power output. A 4 Cycle engine, on the other hand, has more work to do and so creates less power – although this is not the whole story, as we will see shortly.
Set of 6 x 100ml Bottle of 2-Stroke Oil (50:1 mix) for Mantis 2-stroke tillers. Mix each bottle with 5 liters of unleaded gasoline to obtain the 50:1 mixture.
4-stroke Mantis tiller: my machine smokes, there is too much oil in it, how do I clean it? If your machine smokes, if oil flows through the air filter or of the rope is blocked, there is too much oil in the machine. Sometimes, when the machine does not start, it can also be because of an excess of oil in the reservoir.
What lubricant should be used in the tiller transmission case? In the past the rule was: For partial fill-ups (a few ounces or less) use SAE 140, SAE 85W-140 or SAE 80W-90 weight gear oil with an API rating of GL-4 or GL-5. For full replacement use SAE 140 or SAE 85W-140 gear oil with an API rating of GL-4 only.
Ventilation: avoid stagnant air and water. A habitat should have two opposite ventilation areas. (One should be on a lower and the other one on a higher position.)
A rototiller, or tiller, is the heavier and more powerful of the two. Tillers are made for digging deeply and aggressively to break open the soil—for instance, when you`re creating a brand-new garden bed or to getting started at the beginning of the season.
Check to see if the switch and terminals are free from rust and replace any damaged or broken spark plugs wires as necessary. Alternatively, it could be a bad ignition module. A simple way of testing the ignition module is to leave the car idling for 30 minutes and then tap the ignition module with a screwdriver.
Clean or replace spark plug – set gap to . 024-. 028 in. (0.6-0.7 mm).
The spark plug on your Mantis tiller needs to be changed every year (please follow our maintenance tips here). Also, if the machine does not start, it may be because the spark plug is fouled or shorted and you have to change it. New spark plugs are available here.
Why would the engine only run while the choke is on or with repeated manual priming? An engine that requires the choking ( partial or full ) after initial engine warm up is an indication that the engine fuel air mixture system is out of adjustment.

Mantis tiller will not start. Cannot get primer bulb to draw fuel.I replaced all of the lines,primer bulb still won’t work. Tiller will start by priming cylinder by removing spark plug. Help?
ANSWER : Make sure there are no leaks in the bulb. Did you reattach the fuel lijnes correctly? You should feel resistance after pushing 3 or 4 times to ensure fuel is getting to the carb. If necessary replace the bulb. Otherwise check with Mantis at www.mantis.com or give them a call for troubleshooting assistance.

When I Start Mantis Tilleer it starts in gear ( tines are turning)
ANSWER : The Mantis has a speed controlled automatic clutch.

Lower the idle speed by turning the idle screw counter clockwise. The idle screw is attached where the throttle cable meet the carb. The screw has a pointed end that resembles a pencil point.

The engine speed should be adjusted just above stalling.

If the tines turn even when the engine pull rope is pulled, the the clutch is defective and needs repairing.
