Bush Hog Mower

A bush hog mower is a heavy-duty piece of equipment that is used to clear areas of overgrown vegetation. It consists of a large cutting blade that is mounted on the front of a tractor. The blade spins at a high speed and can cut through thick grass, weeds, and brush up to 6 feet tall.

Bush hog mowers are often used by landowners to clear their property for hunting or recreation purposes. They can also be used by farmers to clear fields before planting crops.


If you’re having John Deere MX8 gearbox problems, you’re not alone. Many people have reported issues with this piece of equipment, and it can be a real pain to deal with. Here’s a quick overview of the most common problems and how to fix them.

The first issue is that the gearbox tends to leak oil. This can be a real problem, because it can cause the gears to slip and makes it difficult to change gears smoothly. The best way to fix this is to replace the seals on the gearbox.

Another common problem is that the gears tend to grind when they’re shifting. This can be caused by a variety of things, but the most likely culprit is that the teeth on the gears are worn down. You can try replacing the gears, but if they’re too far gone, you may need to get a new gearbox altogether.

Lastly, some people have reported that their MX8s have been hard to start after sitting for awhile. This is usually due to battery issues, so if your MX8 isn’t starting up easily, check the battery first. If it’s dead, you’ll need to replace it.

If not, then there may be something wrong with the starter motor or solenoid.
