Characteristics

How to start a walk-behind tractor without a starter?

In some cases, operation of the walk-behind tractor becomes impossible due to a breakdown of the trigger mechanism. It can fail anywhere, including in a field, far from home. To solve the problem and start the walk-behind tractor, you don’t always need to take it back to the garage.

Sometimes the design of agricultural units makes it possible to start their power unit without using a starter.

• Unscrew the screws and remove the trigger mechanism;
• Clean the area under the standard starter, removing dirt and moisture from it;
• Under the starter there is a crown necessary for permanent connection of the engine crankshaft with the starter drum. You will need to wind any cable around the rim of this crown, making 4–5 complete windings around the element;
• Lightly pull the free end of the cord towards you until there is resistance - this means that the piston has risen up;
• Turn off the decompressor by moving its lever to the zero position;
• Pull the cable sharply towards you.

How to start a Patriot walk-behind tractor?

To extend the service life of Patriot brand walk-behind tractors, you need to fill them only with pure 92-grade gasoline.

Synthetic motor oil for 4-stroke internal combustion engines is poured into the engine crankcase.

In addition, Patriot brand walk-behind tractors are equipped with a container for pouring oil directly into the air filter of agricultural implements. There are marks on the container where you need to fill the lubricant. The manufacturer does not recommend pouring lubricant above the “bath” provided in the container, since the heated liquid will gradually begin to flow into the engine carburetor.

After this, you can proceed directly to starting the engine. To do this you will need:

• Set the cold start lever to the left position;
• Turn the fuel supply valve to the “On” position;
• Set the ignition switch to the “Start” position;
• Slowly pull the starter cable towards you until resistance appears;
• Pull the starter cable sharply towards you - as a result, the engine should start;
• Give the engine time to warm up;
• Move the throttle control lever to the mid-turn position;

Starting a walk-behind tractor after winter

Such cars tend to have difficulty starting after wintering. First of all, the performance of a walk-behind tractor after winter is affected by the storage conditions of equipment in cold weather. If the car is left over the winter in a cold and damp garage, this can lead to serious problems.

Before starting the walk-behind tractor for the first time this season, it is recommended to change the oil and fuel. It is also necessary to make sure that the performance characteristics of the technical fluids used correspond to the ambient temperature. It is also recommended to read the instructions again to ensure all proportions are observed.

There is a high probability that the walk-behind tractor will not start immediately. This is normal, you need to let the parts warm up well. In addition, it is necessary to warm up the walk-behind tractor even after the engine starts. Over the winter, the fuel could thicken, so it is better not to start using the car intensively right away.

• check if the wires are broken;
• clean the spark plug contact with sandpaper;
• blow out the fuel line.

Engine DM-1-01 and its modifications

The carburetor is equipped with an air filter, allowing easier starting at low temperatures. Automatic decompressor reduces starting force. Stable operation is ensured by contactless electronic ignition.

The engine consists of parts:

• crank mechanism;
• gas distribution systems;
• fuel mechanism;
• air supply and removal of processed gases.

Ignition of the walk-behind tractor is necessary to ensure uninterrupted sparking in the spark plug.

Before starting work, the engine is depreserved. The fuel tank is filled with gasoline in the amount of 2 liters, and the cold (unheated) engine is started.

Some users do not know how to increase the crankshaft speed. Excessive load without warming up the engine leads to rapid wear of the piston pairs and, as a result, causes them to jam.

Starting the engine without a starter

Quite often the starters are the first to fail. Moreover, this can happen at the most inopportune moment. In order not to waste time and money on completely replacing the part, you can start the engine without it.

To start a walk-behind tractor without a starter, just follow these steps:

• Remove the broken part;
• Find a strong rope about a meter long (can be removed from a broken starter);
• In the place where the starter was, you will find a round metal piece. There is a special hole on one of its walls. Thread the rope through it and secure it with a knot;
• Wrap the cable around the part several times until the remainder is about 40 cm.

Working with a walk-behind tractor does not require much physical effort, especially if you install an additional wheel on it. Thanks to the comfortable steering wheel design and the absence of vibration feedback, the operator does not get tired even after long hours of work. Another advantage is the optimal number of gears that can be changed from the remote control on the steering wheel.

Disadvantages of the model noted in the reviews:

• During operation, the belt protective cover rattles strongly;
• on soft soil, the back of the walk-behind tractor sinks, and the user has to constantly lift the unit or attach additional weighting;
• Dust and dirt can accumulate in the open gearbox breather.

Many reviews about the Neva walk-behind tractor, both positive and negative, do not reduce interest in it, since success in work depends not only on the machine itself, but on the skill of the user.

Operation and maintenance of Neva MB-1 MultiAgro walk-behind tractors

What oil and fuel is best to use?

Type of gearbox oil recommended by the manufacturer: transmission oil SAE85W-90 API GL-5 (it is allowed to use TM-5 oil (from -25 to +35) GOST 17479.2-85).

Filling volume l., 1.5. Type of engine oil: in summer it is better to use SAE 10W-30 oil, in winter - SAE 5W-30. Fuel type recommended by the manufacturer: pure gasoline AI - 92, AI - 95.

Add oil only when necessary.

It is recommended to change the oil in Briggs & Stratton engines for the first time 5 hours after the first start of the walk-behind tractor; in the future, in these engines it is recommended to change the oil every 8 hours of operation and before the change of season (spring-summer and winter-autumn).

In Honda engines, the oil is changed within the first 20 hours of operation after the first start, and then at least once every six months.

Tips for the first start-up and running-in of Neva MB1 MultiAGRO walk-behind tractors

The first start-up of the walk-behind tractor must be carried out adhering to the following rules:

1. check the complete set of the walk-behind tractor;
2. start the engine only when the walk-behind tractor is on a flat surface;
3. check that the fuel and oil levels are sufficient;
4. make sure that the threaded connections are securely fastened;
5. start the engine, turning on the ignition smoothly;
6. let the walk-behind tractor run idle for 5-10 minutes;
7. get moving and start working.

Run-in is the period of the first 20 hours of operation of the walk-behind tractor.

During the break-in period, it is important to follow these recommendations:

• do not load the walk-behind tractor at full capacity;
• do not cultivate virgin soil with a new machine - let the equipment “go into operation”, run-in on pre-cultivated land;
• Do not equip the walk-behind tractor with additional cutters, use only the supplied ones;
• change gears only after the rotation of the main pulley has stopped;
• Change the oil after 20 hours of operation.

Gear shift

To correctly change gears on a walk-behind tractor without shortening the “life” of your walk-behind tractor, follow these simple recommendations:

1. Stop the walk-behind tractor to change gears - do not remove the shift knob while the machine is moving!
2. The start of movement is made by moving the engine to ½ of the maximum, then the required gear is engaged. By pressing the clutch smoothly, you will ensure that the walk-behind tractor starts moving. After this, you can gradually increase the number of engine revolutions to give the equipment the required speed.
3. To change gear, release the clutch lever. Make sure that the gear pulley does not rotate, change gear. Resume driving by pressing the clutch. Make all shifts smoothly, without exerting effort or jerking the levers or handle.

Replacing drive belts

NEVA MB-1 walk-behind tractors and their modifications have a built-in front-rear V-belt drive.

To replace the belt in a walk-behind tractor, you need to know the type of belt, its length (you can simply measure it manually), and the degree of tension.

Before replacement, the casing is removed from the V-belt mechanism, and then the back bar is removed from the pulley. The key is used to loosen it, and then the spring-loaded roller is removed. Next, a new belt is tensioned, and those parts that were removed are put back and strengthened.

Belt type suitable for these types of walk-behind tractors: forward drive belt A-1213.

Carburetor adjustment

You can adjust the carburetor yourself only if you already have experience in such repair work.

To adjust you need:

• Unscrew the low and full throttle screws as much as possible;
• start and warm up the engine;
• turn the engine to the lowest speed;
• then achieve stable idle speed and set the maximum idle speed;
• then adjust the minimum engine speed at idle, alternating with the maximum. This is done until the engine starts to idle stably and without any extraneous noise or knocking.

Valve settings

Setting or adjusting the valves is done using wrenches, a screwdriver and a feeler gauge. The essence of the adjustment is to set the standard clearances between the valves, then the engine will operate properly.

To adjust, remove the engine casing, and then the valve box cover, adjust the clearances using a feeler gauge, then replace the box cover and casing.

Changing the gearbox oil of a walk-behind tractor

One of the most important maintenance points for a walk-behind tractor gearbox is timely oil change.

The manufacturer recommends using transmission oil SAE85W-90 API GL-5 for gearboxes of this model and their modifications (it is allowed to use TM-5 oil (from -25 to +35) GOST 17479.2-85). Refill volume: 1.5 l.

Replacing oil seals

The most common problem with oil seals is their leakage. If you notice that oil is leaking, it is better to replace the seals.

This is quite simple to do: you need to remove the seals, clean the shaft from any remaining oil and debris, replace the seals with new ones and install the cover in place, securing it with bolts.

Possible ignition problems

If the ignition is acting up, you probably need to reset it. To do this, remove the spark plugs, wipe the electrodes and, if necessary, clean the spark plugs from carbon deposits or replace them, then set the gap between the electrodes. Next, the spark plug is fixed in the cylinder head, and the crankshaft is rotated.

If the ignition is properly ignited, a white-blue spark will appear.

It is also recommended to check the flywheel and stator; the normal gap between these parts is 0.10 - 0.15 mm. Using a feeler gauge, this gap can be increased. If you don't have a probe, use a razor blade or a landscape sheet folded into four.

Starting a walk-behind tractor after winter

Owners of walk-behind tractors often encounter this problem when the equipment does not want to start after wintering. This is due to storage conditions. If the car was in a cold room with high humidity, then you may end up with a number of serious breakdowns.

Before the first start in the spring, you must completely change the oil and fuel. Ensuring that liquids are at ambient temperature is extremely important.

You may encounter that the walk-behind tractor refuses to start immediately. And this is quite normal. Let the equipment warm up a little. It should warm up even after starting the engine.

If the start of the walk-behind tractor still fails, you need to perform the following steps:

• Bleed the fuel system. There could be residues from gasoline or diesel in it;
• check the spark plug. The contact can even be cleaned a little with sandpaper;
• Check all wiring to ensure there are no breaks or damage.
