Before You Buy an SDLG Grader, Read This Checklist (Including How to Drill Into Concrete)

I'm the office administrator for a 32-person construction and rental company. I manage about $180,000 in yearly purchasing across nine vendor accounts, and I report to both operations and finance. I'm not the mechanic and I'm not the engineer. I'm the person who gets asked why the order didn't work.

This is a six-step checklist I use for everything from an SDLG grader quote to a Westinghouse generator install. It won't make you a product expert. It will keep you from making some of the same expensive mistakes I made after I took over purchasing in 2021.

1. Start with the job, not the brand

When our ops lead asked me to compare an SDLG grader with a used machine, I started by reading brochures. That was backwards. Before the brand matters, you need to know the slope, the material, site access, attachment compatibility, and transport restrictions. I learned this after I ordered a machine that was six inches too wide for the yard gate. Oops.

The same logic applies if you need to drill into concrete. Don't pick a drill and anchor before you know what you're mounting. A shelf bracket and a generator frame are not the same job. The weight of the object changes the anchor type, the hole depth, and the tool you need.

2. Treat market share like a clue, not a verified fact

A sales rep wrote 'SDLG market share in Saudi Arabia: wheel loaders, 70%' in an email and expected us to pass that on to finance. I asked for the source instead. Take that number with a grain of salt—I didn't audit it, and neither should you. What that stat told me was that SDLG had built a strong dealer and parts pipeline in that market. It did not tell me whether the dealer closest to us carried the same parts or answered the phone.

When someone gives you a market share number, ask three questions: Which product category? Which geography? As of what date? If they can't answer, file it under marketing, not evidence.

I've never fully understood why a brand with strong global share can still have weak local support. My best guess is that share reflects past decisions, not the rep who will answer the phone tomorrow.

3. Know how to drill into concrete before you mount anything

Last year, I ordered a Westinghouse generator for a remote yard. The manual said the base frame should be bolted to a concrete pad. I assumed the included stand would be enough. It wasn't. When the electrician asked where the anchor bolts were, I had to figure out how to drill into concrete with a deadline.

Here's the short version:

1. Mark the hole and tape a marker on the masonry bit at the exact depth you need.
2. Use a hammer drill with a masonry bit. A standard drill will make smoke, not progress.
3. Start slow. Once the bit bites, keep steady pressure but don't push hard.
4. Back the bit out every few seconds to clear dust. A shop vac helps.
5. Blow out the hole, then set the anchor. If the anchor spins, the hole is too shallow or too wide.

My first hole was too shallow. The anchor spun, and I had to drill another hole six inches away. Now I always mark the bit with tape. The extra 30 seconds saves you the embarrassment of explaining why the generator pad looks like a connect-the-dots puzzle.

4. Call a dealer who will educate you

When I was researching a hydraulic attachment, I called a small vendor named Crewe Tractor. They didn't sell the brand I was asking about, so they had no obvious reason to help me. The guy on the phone said, 'Don't buy that yet. You need an adapter first, and here's the part number.' That call saved me about $900.

The dealer who educates you before taking your money is the dealer who will help you after the sale. I get why people go with whoever answers the phone first. But a vendor who won't slow you down when you're about to make a mistake is a red flag.

5. Compare final numbers, not the first number

I went back and forth between two dealers for about a week. Dealer A had a lower price and a shorter lead time. Dealer B had a better service agreement and a larger parts inventory. On paper, Dealer A looked like a no-brainer.

When I compared the final quotes side by side, I finally understood why the details matter so much. Dealer A's price didn't include freight. The warranty required us to bring the machine to their shop. After transport, what looked like 6 percent savings became roughly 3 percent extra.

The upside of Dealer A was a lower invoice. The risk was waiting on parts for three weeks if something broke. I kept asking myself whether 4 percent savings was worth a week of downtime. It wasn't.

6. Plan for the day after delivery

The purchase isn't finished when the machine shows up. Ask who installs it, who trains your crew, how long parts take, and who answers when it doesn't start.

For the SDLG grader we eventually bought, the decision came down to dealer proximity and attachment fit. Not horsepower. Not brand history. A machine sitting in another city is just a poster until the dealer delivers and supports it.

If you're mounting a generator, the same rule applies. The smoothest part of any project is the part you thought through before you drilled into concrete.

What I Wish I'd Known Before the Generator Order

The Westinghouse generator itself was fine. The problem was the install. The concrete pad, anchors, weather cover, and an extra breaker were not in the initial quote. When I added them up, the total project cost came in about 18 percent higher than the generator price.

Now I ask for the full project cost before I approve anything. That's the difference between buying a machine and solving a problem.

Common Mistakes I Still Catch Myself Making

• Comparing machines before comparing job requirements. Fix: write the job description down before you open a spec sheet.
• Reading the manual after the order instead of before. That mistake cost me an extra hole in a concrete pad.
• Skipping the spare parts list. For any equipment order, ask for wear items and lead times up front.
• Trusting a verbal 'it'll fit.' Get compatibility statements in writing. If a vendor won't put it in an email, it's not a commitment.

Bottom Line

I'm not a structural engineer or a fleet manager. I'm the office administrator who gets blamed when the order doesn't work. That's why I use this checklist instead of trusting my memory.

If you remember nothing else: start with the job, verify the market share claims, know how to drill into concrete before you need to, and choose a dealer who will tell you when you are about to buy the wrong thing.

An informed buyer is a less expensive buyer. That's the best guarantee I can offer.
