Massey Ferguson 491 Hydraulic Capacity FAQ
Why is the Massey Ferguson 491 hydraulic oil capacity not shown here?
The scraped specs do not list a hydraulic oil capacity for the Massey Ferguson 491, but pump flow is 7.0 gpm (3-point) | 26.5 lpm, system type is open center, and lift is listed as 4199 lbs | 1904 kg. For oil fill amount, use the manual or fill/check procedure, not pump flow or pressure.
Will the Massey Ferguson 491 hydraulics feel fast or slow?
The useful speed clue is 7.0 gpm (3-point) | 26.5 lpm pump flow, below the 14 gpm benchmark for this group. Expect hydraulic functions to be steady rather than fast, especially with loaders or big cylinders.
What matters most for loader speed on the Massey Ferguson 491?
On the Massey Ferguson 491, 7.0 gpm (3-point) | 26.5 lpm pump flow points to slower loader and cylinder movement and 4,199 lb listed lift is the number to watch for implement weight. Flow is the speed number; pressure and lift are the force numbers.
How do you judge hydraulic implement fit on the Massey Ferguson 491?
For implement matching, the useful checks are 7 gpm flow, 4,199 lb listed lift, 2 or 3 remote/valve listing, and II hitch. That combination is more likely to feel slow on loaders, rear remotes and large cylinders and best kept realistic on heavy rear implements, so match the implement by hydraulic demand, hitch category and actual tractor setup rather than model name alone.
Is the Massey Ferguson 491 rear lift capacity strong?
The listed lift figure is 4199 lbs | 1904 kg, below the 7,000 lb benchmark. Keep rear implements realistic and pay attention to weight carried behind the lift points.
Are the Massey Ferguson 491 hydraulic remotes enough?
The Massey Ferguson 491 remote/valve listing is 2 or 3. Because that wording may be optional or configuration-dependent, treat it as a setup check before buying an implement that needs rear hydraulic outlets.
Will the Massey Ferguson 491 hydraulics handle long hydraulic jobs?
The useful heat clues are 7 gpm flow. Heat risk still depends on load, duty cycle, oil level, cooler condition and implement demand.
What do the Massey Ferguson 491 hitch hydraulic specs mean?
The hitch-side hydraulic clues are that rear hitch type is II, hitch control is position control and top-link draft sensing, and listed lift is 4199 lbs | 1904 kg. For real implement choice, hitch category gets it connected, lift capacity gets it raised, and hydraulic flow gets cylinders moving at a usable speed.
What hydraulic system does the Massey Ferguson 491 use?
The hydraulic system is listed as open center with 7.0 gpm (3-point) | 26.5 lpm pump flow. The system type tells you how the hydraulics are arranged; the flow and pressure numbers tell you more about real-world speed and force.
What should you check before servicing the Massey Ferguson 491 hydraulics?
For service planning, the system is listed as open center and flow is listed at 7 gpm. Use the dipstick or sight glass and the operator manual as the final source before servicing.
Hydraulic capacity, pressure, flow, valves, remotes and lift specs can vary by year, market, transmission, pump option, loader package and tractor configuration. Check the operator manual, hydraulic oil dipstick/sight glass, parts book and official masseyferguson.com website before buying hydraulic oil, servicing the system or sizing hydraulic implements.
