Your Massey Ferguson GC1723E is a reliable workhorse, but it needs regular care to stay that way. The 50-hour and 200-hour service intervals are your chance to catch small issues before they become expensive problems. Let’s walk through exactly what you need to do to keep your sub-compact tractor running strong for years to come.
What Makes the GC1723E Service Schedule Different?
The GC1723E is powered by a 22.5 HP Iseki 1.1-liter, 3-cylinder, liquid-cooled diesel engine, and this engine has specific maintenance needs that differ from other tractors in its class. We’ve put together this guide to help you understand the service schedule and tackle the work yourself with confidence.
Your first service happens at 50 hours, and that’s your break-in service. Think of it as flushing out all the microscopic metal particles that come from brand-new parts wearing in together. After that, you’ll service your GC1723E every 200 hours or once a year, whichever comes first. Most homeowners hit the annual mark before they rack up 200 hours, while commercial users might reach those hours every few months.
The Massey GC-Series is designed and manufactured by Iseki in Japan, with Massey designing the visuals. This partnership means you’re getting proven Iseki engineering with Massey Ferguson’s support network. The parts are specific to this collaboration, so you’ll want to make sure you’re using the right filters and fluids when service time rolls around.
MF GC1723E 50-Hour Service Checklist
Your 50-hour service is lighter than the full 200-hour interval, but don’t skip it. This first service removes break-in contaminants that can cause premature wear if left in your engine and hydraulic system. Here’s what needs to happen:
- Engine Oil and Filter Change is the big one at this interval. The engine crankcase with filter holds 0.68 gallons or 2.6 liters of oil. Massey Ferguson recommends their MultiGuard oil, but any quality diesel oil that meets API CJ-4 or CK-4 specifications will work. We stock filters and maintenance parts that meet or exceed OEM specs at prices that make sense.
The oil filter you need is part number 3710280M3, and you’ll also want to grab the oil drain plug O-ring (3707793M1) while you’re at it. Fresh oil and a new filter are cheap insurance against engine wear. Run the engine for five minutes to warm the oil before draining—warm oil flows faster and carries more contaminants with it.
- The Hydraulic System Check is next on your list. You’re not changing the hydraulic fluid yet, just checking the level and condition. The transmission and hydraulic system holds 2.9 gallons or 11.0 liters, and it should look clean with a reddish tint. Dark or milky fluid means you’ve got contamination that needs investigation right away.
- Air Filter Inspection takes just a few minutes but saves you from expensive engine damage. The primary air filter (part number 6259119M91) probably doesn’t need replacement yet at 50 hours unless you’re working in extremely dusty conditions. Pop it out, tap it gently to remove loose dust, and inspect it for damage. If it’s torn or heavily soiled, replace it now rather than waiting.
- Greasing All Fittings is something you should get in the habit of doing regularly. Your GC1723E has grease fittings on the front axle, steering components, and loader pivot points if you have one. Use quality multi-purpose grease and don’t overdo it—one or two pumps per fitting is plenty. You’ll know you’ve got enough when you see a small bead of fresh grease appear.
Complete 200-Hour Service for Your GC1723E
The 200-hour service is where we get serious. This is your regular maintenance interval that keeps everything running smoothly and prevents breakdowns. Block off a few hours, gather your parts, and work through this systematically.
- Engine Oil and Filter Service follows the same process as the 50-hour service. Drain the old oil while it’s warm, replace the filter (3710280M3), install a new drain plug O-ring (3707793M1), and refill with 2.6 liters of fresh diesel oil. Use 15W-40 for warm-weather operation or 5W-30 or 10W-30 for winter or extended cold starts.
- Fuel Filter Replacement is critical for protecting your injection system. The fuel filter for your GC1723E is part number 3608255M1, and you’ll also need the fuel filter O-ring (72100751). Diesel fuel attracts water and contaminants that can damage expensive injectors and pumps. Change this filter religiously at every 200-hour interval—no exceptions.
When you remove the old filter, have a rag ready because some fuel will spill. Clean the mounting area before installing the new filter, and make sure the O-ring is properly seated. After installation, you’ll need to bleed air from the system by operating the primer pump until you see bubble-free fuel.
- Air Filter Replacement is straightforward. Pull out the old primary air filter element (6259119M91) and wipe down the inside of the housing with a clean rag. Install the new filter, making sure it seats properly, then close the housing securely. A poor seal allows unfiltered air into your engine, which leads to rapid wear and potential failure.
- Hydraulic Filter Service protects your expensive hydraulic pumps and cylinders. The hydraulic filter (part number 6258877M91) should be changed at every 200-hour interval along with the suction filter (7069558M92). These filters catch contaminants before they can damage seals, pumps, and control valves. A couple of inexpensive filters now can save you thousands in hydraulic repairs later.

Transmission and Hydraulic Fluid Service
The transmission fluid spec is UTF meeting API GL-4, specifically Permatran 821XL or equivalent, and the change interval is first at 250 hours, then every 300–500 hours or 2 years. At your 200-hour service, you’re checking the level and condition, but not changing it yet unless you’re close to that first 250-hour mark.
The GC1723E uses a hydrostatic transmission, which means the same fluid handles both transmission and hydraulic functions. This makes service simpler, but it also means you can’t use just any hydraulic fluid. UTF hydraulic fluid for Massey Ferguson GC1723E is engineered for hydrostatic pumps and wet clutches—never use ATF or low-grade farm fluid substitutes.
Check the fluid level in the sight glass on the side of the tractor when the engine is cold and on level ground. The level should be in the middle of the glass. If you’re low, top off with the correct Permatran 821XL fluid. Don’t mix different brands or types unless you’re certain they’re compatible—stick with what Massey Ferguson specifies.
Cooling System and Radiator Maintenance
Your GC1723E has a liquid-cooled engine with a cooling system capacity of 1.23 gallons (4.6 liters) plus a 0.26-gallon (1.0 liter) reserve tank. At the 200-hour service, you’re checking the coolant level and inspecting the system, not changing the coolant unless there’s a problem.
The coolant should be a 50/50 mix of ethylene glycol antifreeze and distilled water. Check the level in the overflow reservoir when the engine is cold—it should be between the minimum and maximum marks. If you need to add coolant, use premixed coolant or make sure your mix ratio is correct.
Inspect every coolant hose for cracks, soft spots, bulges, and leaks. Squeeze each hose to check its condition—it should be firm but flexible. Hard, brittle hoses or soft, spongy hoses need replacement before they fail and leave you stranded with an overheated engine.
The radiator needs cleaning at every service interval. Grass clippings, dust, and debris build up on the fins and restrict airflow, which reduces cooling efficiency. Use compressed air to blow the radiator clean from back to front, or use a soft brush and water. Don’t use high-pressure water up close, or you’ll bend the fins.
Greasing Schedule and Best Practices
Regular greasing prevents wear on pivot points and bearings. Your GC1723E has multiple grease fittings that need attention every 50 hours if you’re working the tractor hard, or at least at every 200-hour service for lighter use.
The front axle has fittings on the pivot pin, steering cylinder rod ends, and tie rod ends. The front wheel spindles also need greasing. If you’re running a loader, you’ve got additional fittings on the loader arms, bucket pivots, and mounting pins—these are critical because loader work puts tremendous stress on these components.
Use quality multi-purpose NLGI Grade 2 grease for all fittings. Don’t over-grease—one or two pumps per fitting is usually enough. Over-greasing wastes material and can damage seals. If a fitting won’t take grease, don’t force it. Clean the fitting with a wire brush or replace it if it’s damaged.
Common GC1723E Service Mistakes to Avoid
We’ve seen people make the same mistakes over and over, so learn from others’ experiences. The biggest error is using the wrong hydraulic fluid. Your GC1723E requires a UTF fluid that meets specific specifications for hydrostatic transmissions. Generic hydraulic fluid or tractor fluid from other brands can damage seals and cause shifting problems. Don’t risk your warranty and expensive repairs to save a few dollars on fluid.
Another common mistake is reusing old O-rings and seals. Those drain plug O-rings and filter O-rings are cheap—replace them every time. A $2 O-ring prevents a leak that could cost you hundreds in lost fluid and potential damage. We include these small parts in our filter kits so you don’t have to remember to order them separately.
Don’t skip the fuel filter thinking it looks fine. You can’t see water and contamination inside the filter element. Diesel fuel attracts moisture, and that water can damage your injection pump and injectors—components that cost thousands to replace. Change the fuel filter at every 200-hour service without fail.
Documenting Your Maintenance for Warranty Protection
Keep detailed records of every service you perform. Write down the date, the hour meter reading, what you did, and what parts you used. Take photos of the hour meter and any work you do. This documentation proves you maintained the tractor properly and protects your warranty if something fails.
Save all receipts for parts and fluids. Massey Ferguson can request proof of maintenance if you make a warranty claim. They want to see that you used appropriate fluids and filters and followed the service schedule. Quality aftermarket parts are fine, but keep the documentation showing they meet OEM specifications.
Some owners create a maintenance binder with sections for each service interval. Others use smartphone apps that let you upload photos and receipts. The method doesn’t matter as long as you’re consistent. This record also adds value when it’s time to sell—buyers pay more for tractors with documented maintenance history.
Frequently Asked Questions
Can I use synthetic oil in my GC1723E?
Yes, synthetic diesel oil is permitted and can be beneficial, especially in extreme temperatures. Synthetics are permitted and recommended for sub-compact tractor maintenance in extreme conditions, as they excel at cold-flow startup and can extend change intervals with proper oil analysis. Just make sure it meets API CJ-4 or CK-4 specifications.
What happens if I use the wrong hydraulic fluid in my GC1723E?
Using the wrong-spec fluids WILL void the warranty, which could be an insanely expensive decision later on. UTF fluid is formulated specifically for hydrostatic transmissions with wet clutches. Regular hydraulic fluid doesn’t have the right additives and can cause seal damage, shifting problems, and pump failure.
Do I really need to change all these filters at 200 hours?
Yes. Each filter protects specific components from contamination and wear. The engine oil filter protects bearings and cylinder walls, the fuel filter protects injectors and pumps, the air filter protects the entire engine, and the hydraulic filters protect pumps and cylinders. Skipping filters to save $50 can cost you thousands in repairs.
Can I extend the service interval if I don’t use my tractor much?
Service intervals are based on hours or time, whichever comes first. If you’re not hitting 200 hours in a year, do the service annually. Routine oil changes and fluid checks extend the life of your Massey Ferguson GC1723E. Fluids break down over time even when the tractor isn’t running, and seals can dry out during long periods of inactivity.
