I recently used Mascus, and I got a few serious inquiries pretty quickly.

I would check the transmission fluid and linkage first, especially after sitting for two years.

My Deere 200D LC shows a battery and charging system warning but won’t crank. The batteries and connections check out. Does this excavator have trouble codes that can help diagnose the electrical problem?

After replacing several hydraulic hoses, my excavator’s left pilot valve became slow to respond. Arm lowering and swing have a delay, while the right pilot and second-speed functions work normally. What should I check?

One side of my blade cylinder isn't getting hydraulic fluid. I swapped the hoses and the problem changed. Any idea what I should check?

Just check the frame, deck, brakes, tires, and signs of rust or repairs before you commit.

I'm looking at a Komatsu D39PX with around 3,000 to 4,000 hours. The seller mentioned it may be transferring fluid between the final drive and the HST. Is this a common issue on Komatsu dozers, & is it usually an easy repair?

I'm having a problem with my CAT 308C. The cab still rotates and the tracks work normally, but the boom and bucket have no hydraulic function. Has anyone experienced this issue or know what could be causing it?

I'm servicing the A/C on my Komatsu D320-7 dozer. How much R134a refrigerant and compressor oil should I add? Any recommendations would be appreciated.

If you're patient, you can find some great deals.

My CAT 297D skid steer shut down while working and now it cranks but won't start. It's showing error code E459-2 on the display.

No power on wire 110 definitely sounds like an electrical issue. I'd check the relay, wiring, and any limit switches before digging any deeper.

If it's always blowing on the same cylinders, I'd start looking for a warped head, liner height issues, or a crack in the block or head. Repeated failures in the same spot usually point to an underlying mechanical problem, not just a bad gasket.

If the blade moves smoothly but won't lift the machine under load, the most common causes are a relief valve opening too early, internal cylinder seal bypass, or low system pressure from the pump.

Mine starts and runs fine, but it loses power under load and feels like it wants to stall. I’m seeing a lot of people mention fuel filters, clogged fuel lines, lift pumps, or fuel supply issues on these machines.
