How-tos

Using the wrong chainsaw bar oil weight can affect your cutting performance, shorten your chainsaw’s life and even bring about costly maintenance and repairs. Thinner oils like SAE 10W are ideal for cold weather operation and softwood cuts, while thicker oils like SAE 40W are better for hot temperatures and hardwoods. In this guide, we’ll dive into more than just different chainsaw bar oil weights and how to choose the right one for your specific needs.

Husqvarna belt size chart by model and part number. The right belt for a Husqvarna machine is usually found by part number, not by guesswork and not by deck size alone. A proper belt size chart should help you match the belt type, width, and length before you order. Going by deck size alone is often not enough, especially when similar machines use different belt routes. Start with the model if you know it. But if the old belt number is still readable, use that first. Part numbers point to the exact belt because similar decks may use different routing and pulley layouts. Belt length must be close enough for the pulley path and tensioner range. Even a small difference can affect belt tracking and blade speed. Before ordering, confirm four things in order: machine model, belt function, belt width, and belt length. The deck belt drives the blades. The drive belt moves the machine. If a belt keeps jumping off, check the idlers, keepers, springs, and pulley alignment too.

You may often see or drive a semi-truck on the highway but have you wondered how much those behemoths weigh? An empty semi-truck usually weighs about 30,000 to 35,000 pounds, while a fully loaded one weighs no more than 80,000 pounds without special permits. But how does the semi-truck weight distribute between the tractor and trailer? What if you exceed the limits? Let’s dive in together.

How to stop wheel spin: compact tractor ballast box guide. If a Kubota L3902 starts spinning while pulling a 5-foot disc harrow in sandy soil, the usual cause is simple. Not enough usable weight on the drive tires for the draft load and disc angle. A flatter gang angle rolls easier but barely cuts. A steeper angle cuts better but asks for more traction than the tractor can hold. Loose sand gives poor grip even before the disc starts to bite. Then the disc angle adds draft load. On a light compact tractor, that extra pull can overcome rear tire grip long before engine power runs out. Loaded rear tires are often the most useful starting point. They add weight directly to the drive wheels, lower the center of gravity, and do not take away your hitch. Wheel weights help if more grip is still needed. A 3-point ballast box is better for loader work. It offsets front load and protects the front axle. For discing, rear tire ballast matters more. Reduce gang angle slightly. Check tire pressure. Make sure the disc is in good shape. Add traction first, then add bite. Two lighter passes often work better than one aggressive pass.

Discovering metal in the hydraulic filter is a critical warning sign of failing pumps, motors, or cylinders. This guide helps you decode the metal debris, pinpoint the broken component, and safely flush your entire system.

Should you add a tractor bucket tooth bar for packed dirt? A tooth bar helps, but it is not the whole fix. On a compact tractor, teeth give the bucket more bite. They cut at several points instead of one flat edge. That helps with packed dirt, roots, brush, gravel, and back dragging. It also protects the bucket edge. But it does not change lift capacity or traction. Hard clay still needs to be loosened first. That is the part many people miss. If packed soil is beating the bucket, do not charge harder. Loosen the ground first. Use a box blade with scarifiers to rip the surface. Make another pass if needed. Then scoop with the loader. Grade and smooth on the final pass. That sequence reduces shock load on the loader. It also puts less strain on pins, hydraulic hoses, and front axle parts. If the main problem is hardpan, a box blade with rippers is the better first buy than a tooth bar.

Ever wondered what powers the absolute giants of the highway? In the United States, commercial vehicles are categorized into eight distinct classes based on their Gross Vehicle Weight Rating (GVWR), with Class 8 representing the heaviest rigs on the road. These behemoths weigh over 33,000 pounds and haul up to 80,000 pounds of freight. While these heavy-duty machines are the undisputed backbone of North American logistics, keeping them running smoothly is no simple task. What actually goes into building these Class 8 trucks, and which easily overlooked maintenance mistake could quietly ground your entire fleet? Let’s dive in.

Learn practical steps for removing a stubborn hydraulic cylinder gland: secure and drain the cylinder, use a stout spanner or pipe wrench with a cheater bar, apply penetrating oil or heat, and inspect or replace seals to avoid leaks and premature failures.

How to operate a mini excavator: a beginner’s guide. How to operate a mini excavator comes down to a few steps. First, inspect the machine. Then drop the blade for stability, learn the joystick pattern, and use a smooth dig, swing, and dump cycle. Moving the machine is easy. Using it well takes more attention. Before startup, check the ground condition, work zone, underground utilities, overhead clearance, hydraulic hoses, tracks, and fluids. Use three-point contact when entering the cab. Fasten the seatbelt. Lower the blade before digging. The left joystick controls stick and swing. The right joystick controls boom and bucket. The cleanest bucket fill comes from combining bucket curl with stick retraction, not from forcing the bucket straight down. Keep the bucket low when traveling. Travel straight up or down a slope, not across it. Take smaller controlled cuts. Keep spoil on one side.

This guide to 3-point hitch sway adjustment shows how to center the implement, tighten turnbuckles or stabilizer bars, and eliminate pin play with bushings so rotary cutters and blades run true and won’t strike tires.

Fixing a Kubota 3-point hitch that won’t lift is often simpler than you think. This guide covers the most common culprits, from adjusting the hydraulic flow control knob to checking fluid levels, filters, and the pump.

Oiling your chainsaw is crucial to extend its service life. This includes oiling the chainsaw chain and chainsaw bar. For manual oiling, the process is as simple as putting a little chainsaw oil directly on the chain links and spreading the oil over the whole chainsaw chain with a small brush. But how to choose the oil? How often to change the chain oil? This guide will cover how to oil a chainsaw with detailed instructions.
