EP-HH-YG45*220 Harvester Hydraulic Cylinder

Farming’s no easy task, especially when you’re up against long days in the field and machinery that can’t afford to let you down. That’s why Raydafon built the EP-HH-YG45*220 Harvester Hydraulic Cylinder—to be the workhorse behind combine harvesters and sugarcane harvesters, tackling the tough lifting and steering jobs that keep harvests moving.

Out in the wheat or corn fields, a combine’s got to lift heavy headers, adjust cutting heights, and steer smoothly over bumpy ground. This cylinder steps up as a reliable agricultural harvester hydraulic cylinder, pumping out steady, strong thrust to make those movements precise. No more jerky lifts or slow responses—just the kind of control that keeps you from missing a single stalk, even when the clock is ticking to beat the rain.

Sugarcane fields are a whole different challenge. Thick stalks, muddy terrain, and relentless sun can wear out parts fast. But this cylinder’s built tough: high-strength alloy steel stands up to the constant pushing and pulling, while premium seals keep hydraulic fluid locked in and dirt, sap, and water out. It’s the kind of durable harvester hydraulic cylinder that won’t quit halfway through a 12-hour shift, even when the humidity’s thick enough to cut.

What’s really handy is how well it fits into different setups. Whether you’re running a standard combine or a modified sugarcane harvester, it works as a solid hydraulic cylinder for combine harvesters right out of the box. And if your machine needs something a little different—maybe a longer stroke or a custom mount—Raydafon can tweak it into a custom harvester hydraulic cylinder that fits like a glove. No more rigging up parts that don’t quite match.

Quality isn’t an afterthought here, either. Their factory in China sticks to ISO 9001 standards, so every cylinder gets tested hard before it leaves. They check how it handles pressure, how it holds up after thousands of cycles, and even how it performs in extreme heat or cold. It’s not just about meeting rules—it’s about making sure it works when you’re knee-deep in harvest and can’t afford a breakdown.

Best of all, it doesn’t break the bank. For all that strength and reliability, Raydafon keeps the price competitive, so even smaller farms can get a part that lasts. When you’re out there day after day, relying on your harvester to bring in the crop, this cylinder is the kind of part you’ll be glad you invested in—quiet, tough, and always ready to get the job done.

Maintenance and Troubleshooting

Keeping your harvester’s hydraulic cylinder in top shape is key to avoiding costly downtime during harvest. Whether you’re using the EP-HH-YG45*220 or another harvester hydraulic cylinder, knowing how to spot issues, install it right, and care for it can save you a lot of headaches. Here’s what you need to know:

How to Tell If Your Lift Cylinder Is Worn Out

A tired agricultural harvester hydraulic cylinder usually sends clear signals—it’s just a matter of knowing what to look for. One big red flag is header drift: if your harvester’s header slowly sinks when the machine is off, or drops a little when you’re not actively lifting it, that’s a sign the internal seals are wearing out. When seals fail, hydraulic fluid slips past them, making it hard to hold position—bad news for keeping your cutter at the right height.

Jerky movements are another warning. If lifting the header feels choppy or hesitant, like it’s catching or struggling, that could mean a blocked port, worn piston, or contaminated fluid. This isn’t just annoying; it can throw off your harvest, leaving crops uncut or damaged.

And don’t ignore leaks. A little drip around the rod seal or end caps might seem minor, but it’s a sign of trouble. Leaks let dirt, chaff, and moisture sneak in, which grinds away at internal parts. Plus, losing fluid means less pressure—so your durable harvester hydraulic cylinder won’t work as hard as it should. If you see any of these, it’s time to check (or replace) the cylinder.

Best Ways to Install It Right

Putting in a new EP-HH-YG45*220? Do it right, and it’ll last longer. Start by safety first: always bleed the hydraulic system to release pressure. No one wants a cylinder shooting out unexpectedly while you’re working on it.

Next, clean everything. Wipe down the mounting pins and bushings with a rag—any dirt or crop residue left there can throw the cylinder out of alignment, causing extra wear. A misaligned cylinder works harder, wears faster, and might even bend over time.

When you slide the new cylinder into place, use fresh hydraulic fluid to top off the system. Then, work the cylinder a few times—extend and retract it fully, but without a load. This purges air bubbles, which can make the cylinder feel “spongy” and reduce its power. Get the air out, and you’ll avoid stressing parts when you start harvesting for real.

Take your time here. A 10-minute extra check during installation can save hours of fixing it later.

How to Make Your Hydraulic Cylinder Last Longer

With regular care, your custom harvester hydraulic cylinder (or standard one) can stick around for multiple seasons. Start with the piston rod: after every day in the field, wipe it down with a clean cloth. Mud, straw, and grit act like sandpaper on the rod and seal—wipe them off, and you’ll prevent leaks.

Check hoses often, too. Cracks, bulges, or frayed ends mean they’re ready to fail. A burst hose can dump fluid fast, leaving you stranded in the field. Swap out old hoses before they break, and you’ll avoid bigger messes.

And keep the fluid clean. Hydraulic fluid is the lifeblood of the system—dirty fluid clogs ports and scratches parts. Change the filter as often as your harvester’s manual says (usually every 500 hours), and check the fluid level regularly. If it looks cloudy or has bits floating in it, drain and replace it.

Small steps, but they add up. A little care means your harvester hydraulic cylinder works when you need it most—no surprises during harvest.

By watching for wear, installing carefully, and keeping it clean, you’ll get the most out of your cylinder. After all, harvest waits for no one—so keep that cylinder in shape, and it’ll keep up with you.

Product Features

Harvest season waits for no one, and your equipment can’t afford to lag—especially when it comes to the hydraulic cylinders that power your harvester’s most critical moves. The EP-HH-YG45*220 is built to be more than just a part; it’s a heavy-duty harvester hydraulic cylinder engineered to keep up with the grind of modern farming, whether you’re tearing through cornfields, navigating wheat stubble, or tackling thick soybean patches. Let’s break down what makes it stand out.

Power to Handle the Toughest Loads

When you’re lifting a fully loaded draper header or adjusting a corn head heavy with ears, you need a cylinder that doesn’t flinch. The EP-HH-YG45*220 delivers with its 45mm bore diameter, cranking out the force to handle even the heftiest attachments. This high-force harvester hydraulic cylinder shines in tasks like raising headers over rocks, lowering reels to catch low-lying crops, or tilting platforms to dump grain—no straining, no hesitation.

Its 220mm stroke length is another win. Whether you’re fine-tuning the reel height for short barley or extending the header to reach tall corn, there’s enough range to get the job done. This flexibility makes it a top pick as a multi-crop harvester hydraulic cylinder, adapting seamlessly across different crops without sacrificing precision.

Built to Outlast the Field

Harvest fields are brutal on equipment: mud clings, chaff scratches, and rain brings rust. But this cylinder is armored to survive. The piston rod wears a thick chrome plating, tough enough to resist scrapes from rocks or crop debris—so even after weeks in dusty fields, it slides like new. Inside, the seals are made from industrial-grade, oil-resistant rubber, designed to hold tight against pressure. No more “header drift” from leaky seals, and no wasted hydraulic fluid—this is a long-life harvester hydraulic cylinder that keeps going, season after season.

It’s also built to fight corrosion, a must for wetland harvester hydraulic cylinder needs. Whether you’re working in damp rice paddies or dewy morning wheat fields, the cylinder’s coating and seals stand up to moisture, keeping internal parts safe from rust and decay.

Slides Right In, No Fuss

Swapping out a worn cylinder shouldn’t mean missing a day of harvest. The EP-HH-YG45*220 is a direct-fit harvester hydraulic cylinder, designed to match OEM specs for popular combines. Its mounting pins line up perfectly, hydraulic ports sit in the right spots, and there’s no need to drill new holes or bend brackets. Mechanics love it: pull the old cylinder, bolt this one in, and you’re back in the field in under an hour. For farms running tight schedules, that’s a game-changer.

Safe, Smooth, and in Control

Farming’s unpredictable—one wrong bump or jammed crop can stress your equipment. That’s why this cylinder includes a built-in pressure relief valve, a key feature of a safety-rated harvester hydraulic cylinder. If the load spikes unexpectedly (say, a clump of corn jams the header), the valve eases pressure to protect the cylinder and your harvester from damage.

Operators will notice the difference in control, too. This precision-stroke harvester hydraulic cylinder moves with zero jerking or lag. Adjust the reel to gently guide wheat into the cutter, or lift the header in tiny increments to avoid crushing soybeans—every movement is steady and responsive. That smooth action cuts down on crop loss and makes long days in the cab less tiring.

Whether you’re a custom harvester tackling 10,000 acres or a family farm tending to a few hundred, the EP-HH-YG45*220 brings it all: the power of a heavy-duty harvester hydraulic cylinder, the durability of a long-life model, and the precision to handle any crop. It’s not just a cylinder—it’s a tool that keeps your harvest on track, from dawn till dusk.
