Tips for maintaining your heavy machinery

Keeping your heavy machinery in top condition takes a bit of effort and know-how. To make sure your gear runs smoother for longer and avoids costly breakdowns, follow these simple yet effective maintenance tips:

Give us a call

Regular Inspections

A small issue can turn into a costly breakdown if left unchecked. Make it a habit to inspect your machinery for leaks, wear and loose components. Catching problems early means fewer surprises and less downtime.

Frequent Lubrication

Friction is the enemy of moving parts. Keep everything well-lubed to prevent excessive wear, overheating and breakdowns. Use the right grease and oil for your equipment, and don’t skip on quality.

Keep it clean

Dirt, dust and grime aren’t just cosmetic issues – they can clog filters, damage components, and reduce efficiency. Regularly clean your machinery, especially air filters, cooling systems, and moving parts, to keep it performing at its best.

Stick to maintenance schedules

Manufacturers set service schedules for a reason. Whether it’s oil changes, filter replacements, or full inspections, sticking to a proper maintenance routine keeps your machinery running longer and stronger. Don’t wait for a problem to force you into the workshop – stay ahead of the game.

I wouldn’t bring my mower here after my experience. I came with my Ford Ranger after Ford dealer quoted me 3k for a new ECU arguably not covered under warranty. Andrew told me they need to do they own diagnostic which would cost $140 before proceeding which I agree too.Two days later I came to the shop to check on the progress to find out my car wasn’t there but at some auto election shop for further diagnostics. While waiting for my car I was told it’s definitely not ECU but crank shaft and timing belt not syncing and most likely I would need a new engine. Anthony sounded super confident about it. In 30 min wait my car arrived with a bill of $1485 from auto election diagnostics plus $140. After back and forth I refused to pay $1485 as no one called me to ask for permission for more advanced diagnostics. I ended up paying $140 for I don’t know what exactly, as they refused to give me any paperwork.In the end I took my car next day to different Ford Dealer who whin couple of hours found damaged crank sensor wire rubbing on diff hose. All got fixed under warranty.Imagine if I listened to Anthony and end up putting a new motor!! How many people accept their “diagnostic” and needlessly spends thousands of dollars.

We were both very impressed with the thorough diagnostic approach (not just with diagnostic equipment) but with searching physically ,to resolve the difficult problems with our vehicle, that had been looked at by other mechanics but unresolved.We very much appreciate the effort of Willy and Doug and their expertise.
