How-tos

The Kubota B7100 rolled off the line from 1976 to 1985, and it’s a compact utility tractor with 16 HP at the engine, 13 at the PTO, and a Category I 3-point hitch. It’s well-suited for light mowing, towing, and touching up driveways—especially on properties where space is tight. It weighs about 1,080 lbs and flows just 3 GPM of hydraulic fluid, so heavy loader work or big attachments aren’t really in its wheelhouse. We’ll also compare it to the B1600DT—more power and loader capability, but less compact and simpler.

A properly repaired oil pan might last the rest of the service life of your vehicle, but a repaired oil pan lacks the structural integrity of a new one. If you want to keep your vehicle running for an extra five years or more, an oil pan replacement is a wiser option. Although it costs much more to replace the oil pan in the short run than repairing it, it’s recommended to have a new replacement for the long-term benefits. A new oil pan replacement at a store costs between $150 and $700 with extra installation costs of $200 to $400. Replacing the oil pan is much easier than repairing and a DIYer can buy the oil pan and gasket from reliable aftermarket supplier to for budget-saving purpose.

Don’t rely on an OEM number alone. This guide explains how to confirm tractor hydraulic pump compatibility beyond the part number. Learn to check rotation, measure the mounting flange and shaft, and match performance specs to get the right part.

Choosing the right tractor box blade comes down to four things: matching width to horsepower, knowing when a box blade is the right tool, picking the right features, and comparing it to other implements. A 4-foot blade suits 15–25 HP sub-compacts; 5-foot for 25–40 HP compacts; 6–7 feet for 45–70 HP utility tractors. The blade must cover your rear tire tracks. Key features include scarifier shanks (at least four with adjustable depth) and replaceable reversible cutting edges. Weight prevents bouncing—4-foot blades run 380–450 lb, 6-foot 500–750 lb. Box blades excel at rough grading and driveway repair. Replace worn shanks and cutting edges to maintain performance.

Knowing your exact model year and serial number ensures you get the right parts every time you shop for upgrades or replacements. We hope reading this easy guide means you no longer need to ask “What year is my EZGO golf cart?”

With over 30 years of production history under its belt, the CAT 3406 has gone from the mechanical A-model (1973) to the electronic E-model (1993–2007). It’s a 14.6-liter big bore that puts out anywhere from 275 to 800 horsepower, which explains why it’s shown up in so many trucks and machines over the years. Here we’ll go through the engine’s background, the serial prefixes you need to know (2EK, 1LW, 5DS, and a few others), the specs that matter, and the usual trouble spots—surging, running hot, oil level rising on its own, and electronics acting up. Keep up with the service intervals—daily, 250, 500, 1,000, and 2,000 hours—and you can expect 12,000 to 15,000 hours out of it before a major overhaul. And don’t forget: check that serial prefix before you start ordering.

The TCM controls shift timing, line pressure, and torque converter lockup. When it fails, rough shifts, delayed engagement, or a stuck gear can mimic internal damage. This guide covers TCM diagnosis—module location, fault code reading, and power/wiring checks—along with two reset methods: power-down and adaptive reset with a diagnostic tool. After resetting, a relearn procedure is essential for smooth operation. A reset is only effective if the hardware is sound. If symptoms return, inspect solenoids, clutch packs, fluid, and the valve body gasket.

When it comes to selecting the right parts for your Yamaha outboard, it’s essential to have accurate information about your motor. In this guide, we’ll walk you through Yamaha serial number lookup and how to decode the serial numebr and model code of your Yamaha outboard motor

A P0402 code tells you too much exhaust gas is being recirculated back into the engine—and that means power loss, black smoke, rough idle, and limp mode on excavators, dozers, loaders, and tractors. In this guide, we’ll cover what to look for, what’s actually causing it (carbon buildup from too much light-load running, vibration-cracked piping, and plugged Delta-P sensor lines), and a step-by-step fix: check live data, inspect the piping, clean the sampling ports, test the EGR valve, and check the wiring. One thing to avoid: don’t start by replacing the EGR valve. A good cleaning of the valve and sensor lines clears up most cases. A few prevention habits—cutting down on idle time and keeping up with crankcase filter changes—go a long way toward keeping P0402 from showing up again.
