The fuse panel on a Bobcat 863 skid steer loader is typically located in one of several places. It could be located in the cab of the machine, near the floor on the left or right side. It could also be located in the engine compartment, either on the side or on the firewall.
To check the fuse for the blower motor and windshield wipers, you will need to locate the fuse panel and then locate the specific fuse for these systems. The fuse panel should have a diagram that shows the location of each fuse and its corresponding circuit. If the fuse is blown, you can replace it with a new one of the same amperage rating.
If you are unable to locate the fuse panel or the specific fuse for the blower motor and windshield wipers, you may want to consult the operator's manual for your Bobcat 863. This should provide you with more detailed information on the location of the fuse panel and the specific fuses for these systems. Alternatively, you can also try contacting a Bobcat dealer or a qualified repair technician for assistance.

looks like you may have put the gear shaft back together with reverse gear or shift linkage in wrong position?

Since you didn't specify, I'm taking a guess it's making noise only when you're driving it, not when sitting an operating the bucket or aux. hydraulics. You have to describe the noise, is it a whine, groan, high or low pitched, grinding, crushing marbles, what? Describe the sound.

Check drive belt. has it come off the pulleys or is it broken. They do those things once in a while. Check for broken shear pins in the pulleys as well

Choke lever broken? Whats the problem?

You know you're posting in snow blowers, right genius?

Can anyone help me with a john deer 826 snow blower that won't engage in forward motion?

If you locate the model number of your motor you should be able to download an Operator's Manual for the motor form this site:

Is this an actual Tecumseh brand snow blower or another brand with a Tecumseh motor installed?
