Troubleshooting

Diagnosing issues with your John Deere 826 snowblower can seem daunting, but by systematically approaching potential problems, you can often identify the root cause and implement a solution. This chapter provides a detailed guide to troubleshooting common issues you might encounter while operating or maintaining your snowblower. It is important to remember that safety should always be your priority. Before attempting any repairs, ensure the engine is switched off, the spark plug wire is disconnected, and the snowblower has cooled down completely. Refer to the specific section below that best matches the problem you're experiencing.

Engine Starting Problems

A snowblower that refuses to start is a common frustration during the winter months. Begin by checking the simplest potential causes. First, verify that there is sufficient fuel in the tank and that the fuel valve is in the "ON" position. Stale fuel can also be a major culprit, especially if the snowblower has been sitting idle for several months. Drain the old fuel and replace it with fresh gasoline. Next, inspect the spark plug for cleanliness and proper gap. A fouled or improperly gapped spark plug can prevent the engine from igniting the fuel-air mixture. Clean the plug or replace it if necessary.

If the fuel and spark plug are in good order, the problem might lie within the carburetor. A clogged carburetor can restrict fuel flow to the engine. Try using carburetor cleaner to dissolve any accumulated deposits. In more severe cases, you may need to disassemble and clean the carburetor thoroughly or even replace it. Also, check the choke. If the choke is not engaged properly, especially in cold weather, the engine may not receive a rich enough fuel mixture to start. Make sure the choke lever is in the correct position for starting.

Finally, if you've addressed the fuel and spark issues and the snowblower still won't start, the problem could be a lack of compression. This is less common but more serious. Check the cylinder compression using a compression tester. Low compression can indicate worn piston rings, damaged valves, or a blown head gasket. Addressing these issues typically requires the expertise of a qualified mechanic.

Poor Snow Throwing Performance

Reduced snow-throwing distance or inefficient snow removal can be caused by several factors. Begin by inspecting the condition of the scraper blade and the auger blades. A worn or damaged scraper blade will not effectively clear the snow from the surface. Similarly, worn or bent auger blades will not properly feed snow into the impeller. Replace these parts if they are worn or damaged. Make sure the auger housing is free of obstructions. Ice or packed snow can build up inside the housing and impede the flow of snow.

Another common cause of poor performance is a slipping or broken drive belt. The drive belt transfers power from the engine to the auger and impeller. Inspect the belts for wear, cracks, or fraying. Replace any belts that show signs of damage. Also, check the tension of the drive belts. Loose belts can slip, reducing the power delivered to the auger and impeller. Adjust the belt tension according to the manufacturer's specifications.

Lastly, ensure that the impeller is rotating freely. The impeller is responsible for throwing the snow out of the chute. If the impeller is damaged or obstructed, it will not be able to perform its function effectively. Check for any debris or ice that might be preventing the impeller from rotating smoothly.

Chute Clogging Issues

A clogged discharge chute can interrupt your snow removal efforts and is usually caused by wet, heavy snow. Try using a clean-out tool (usually provided with the snowblower) to clear the blockage. Always shut off the engine before reaching into the chute to remove any obstructions. Consider applying a non-stick spray (like silicone lubricant) to the inside of the chute. This can help prevent snow from sticking to the chute walls and reduce the likelihood of clogs.

If you frequently experience chute clogging, it could be a sign that the snowblower is not operating at its optimal speed. Make sure the engine is running at the correct RPM. Low engine speed can reduce the force with which the snow is thrown out of the chute, increasing the risk of clogging. Adjust the engine speed according to the manufacturer's instructions. Also, check the condition of the discharge chute itself. Dents or bends in the chute can create areas where snow can accumulate and cause clogs.

In addition to snow conditions and equipment issues, operator technique can also influence clogging. Avoid trying to clear excessively deep snow in a single pass. Take smaller bites and overlap your passes to reduce the load on the snowblower. If the snow is particularly wet and heavy, consider waiting for it to dry out slightly before attempting to clear it.

Drive System Problems

Problems with the drive system can manifest as a loss of traction, jerky movement, or an inability to move forward or backward. Begin by checking the tire pressure. Low tire pressure can reduce traction and make it difficult for the snowblower to move effectively, particularly on slippery surfaces. Inflate the tires to the recommended pressure. If your snowblower has a drive system with multiple speeds, ensure that the speed selector is properly engaged. A partially engaged speed selector can cause the snowblower to move erratically.

Next, inspect the drive belt or chain that transmits power to the wheels or tracks. A worn or loose drive belt or chain can slip, reducing traction and causing jerky movement. Replace or tighten the belt or chain as needed. Check the condition of the drive wheels or tracks. Worn or damaged wheels or tracks will not provide adequate traction. Replace them if necessary. Consider using tire chains or snow tracks for added traction in especially icy or snowy conditions.

Finally, examine the internal components of the transmission or drive system. This may require consulting the service manual and potentially disassembling the drive system. Look for worn gears, broken linkages, or other signs of damage. Repairing or replacing these components may require specialized tools and expertise. If you are not comfortable performing this type of repair, it is best to take your snowblower to a qualified mechanic.

If your John Deere 826 is equipped with an electric start, proper battery care during storage is paramount to ensuring it's ready to go when you need it. Batteries can lose charge over time, especially in cold conditions, and prolonged periods of inactivity can lead to sulfation, a condition that reduces the battery's ability to hold a charge. To prevent these issues, it's recommended to remove the battery from the snowblower and store it in a cool, dry place, away from direct sunlight and extreme temperatures.

Before storing the battery, clean the terminals and apply a thin coat of petroleum jelly to prevent corrosion. Consider using a battery maintainer or trickle charger to keep the battery at its optimal charge level during the off-season. These devices automatically monitor the battery's voltage and provide a small current to compensate for self-discharge, preventing sulfation and extending the battery's lifespan. Check the battery's voltage periodically and recharge it as needed to ensure it remains in good condition.

Covering and Storage Location

Choosing the right storage location and providing adequate protection for your snowblower is the final step in preparing it for the off-season. Ideally, you should store your John Deere 826 in a dry, sheltered location, such as a garage, shed, or carport. This will protect it from the elements, including rain, snow, sun, and wind, which can cause rust, corrosion, and damage to the machine's components. Avoid storing it outdoors, if possible, as this will significantly shorten its lifespan.

Regardless of where you store your snowblower, it's a good idea to cover it with a protective cover. A breathable cover will help to keep dust, dirt, and pests out, while also allowing moisture to escape, preventing condensation and rust. Make sure the cover fits snugly and securely to prevent it from being blown away by the wind. Finally, consider raising the snowblower slightly off the ground to prevent moisture from accumulating underneath it. This can be achieved by placing it on wooden blocks or a pallet.
