I'm looking for better traction on muddy job sites. Can I use snow chains or aggressive tread tires, or could that damage the drive motors? Also, should both drive wheels spin in mud, or is it normal for only one to spin?

Hitachi EX120-5 excavator runs fine at idle, but after traveling about 30 meters or using the boom, the engine struggles and stalls. Someone suggested the stepping motor could be the issue. Does it need calibration after replacement, or could this be something else? Has anyone experienced this...

I recently purchased 7FB710 and 7FB711 from Kiewit in Dallas, Texas, and I'm currently shipping them to Australia. I'm interested in learning more about their history, maintenance, and previous work. I'd appreciate any information or experiences you can share.

I'm thinking about buying a 2005 Cat 325C zero-tail-swing excavator and was wondering how difficult they are to service. Is the engine compartment too cramped, or is routine maintenance still fairly straightforward? I'd appreciate any real-world experiences from owners or mechanics.

My 2001 Volvo EC240LC started up fine this morning, but the final drive quit working and the bucket curl became extremely slow in both directions. The track will move normally only when I press the auxiliary pedal while tracking. Any ideas on what could cause both issues at once?

I'm working on a Volvo A25C and currently have no headlights, tail lights, brake lights, interior lights, or tachometer working. The machine runs, but it seems like everything related to the electrical side stopped at once. I'm trying to figure out the best place to start checking before...

Mine changes tone when put in gear and also when using the trans disengage switch. I also found some metal and brass shavings in the filter. Could air in the system cause this, or is it pointing to something more serious?

Hey folks, I occasionally haul oversized equipment on a flatbed, and dealing with wide load permits can sometimes be more challenging than the haul itself. How do you handle permits, route planning, and escort requirements in your area, and do you have any tips for making the process smoother?
