Buying a backhoe loader is not a small decision. One wrong pick and you end up with a machine that either cannot handle the job or burns more fuel than it should. On a construction site, both situations cost money every single day.
CASE is one of the most recognised backhoe loader brands in India. Their machines are used on road projects, trenching work, material handling, and urban construction. But CASE makes multiple models, and each one is built around a different set of job requirements.
This blog covers four CASE backhoe loader models the 770NX, the 851NX, the 770 EX Plus, and the 770NX MAGNUM. You will get the full specs, what each machine does best, and a clear comparison so you can decide which one fits your site.
CASE Construction Equipment has been present in India for many years. Their backhoe loaders are used by contractors, infrastructure companies, and rental businesses across the country. All four models covered here sit in the 74 HP range and meet CEV Stage V or equivalent emission norms. Operating weight ranges from 7,600 kg to just under 8,000 kg. Let us go through each one.

The CASE 770NX runs a 2.8-litre CNH F3B Stage V CRDI engine producing 74 HP and 375 Nm of torque at 1,400 RPM. This model offers a variable hydraulic system that delivers 119 LPM flow for faster cycle times and smoother control.
For loading, the 1.1 m³ bucket and 2.73 m dump height make truck loading quick. Maximum payload is 1,925 kg. For excavation, it digs to 4.4 m with a 0.26 m³ backhoe bucket.
The three working modes ECO, STD, and POWER match engine output to the task. In ECO mode, fuel savings reach up to 20%. The machine also comes in 60 HP and 74 HP power curves. The myCASE telematics system monitors fuel consumption, machine health, and idle hours remotely. It also works in extreme temperatures down to minus 20 degrees Celsius.
Best for: Contractors who want a Stage V machine with fuel control, telematics, and standard digging depth for everyday construction and utility work.

The CASE 851NX is powered by a 4-cylinder turbocharged intercooled engine delivering 375 Nm of torque. Operating weight is 7,700 to 7,800 kg. The heavier build improves ground grip and reduces machine vibration during deep digging.
The hydraulic system is an open-centre load-sensing setup with 143 LPM flow 24 LPM more than the 770NX giving quicker boom and bucket response during continuous trenching. The loader lifts 3,650 kg at maximum height. The backhoe produces up to 6,550 kgf of breakout force for cutting through compact or clay-heavy soil.
The 851NX digs to 4.7 m with a 1.2 cum loader bucket. That is 0.3 m more depth and a larger bucket compared to the 770NX. It also meets CEV Stage V norms and offers ECO, STD, and POWER modes.
Best for: Contractors doing heavy trenching, deep excavation, or large-volume truck loading where breakout force and hydraulic flow matter.

CASE 770 EX Plus features a 3,840 cc engine that adheres to the Tier 4B and CEV BS-IV standards. It generates 74 HP and 340 Nm of torque, which is slightly less than that of the NX versions. The heaviest machine in this group is the operating weight of 7,955 kg.
The bucket of the loader can accommodate 1.1 cum. There is a 45 degree dump angle, a dump height of 2,730 mm, a load-over height of 3,300 mm and a reach at ground of 1,980 mm.
The added weight provides stability on sloping or soft surface when operating with the bucket loaded. This is an older generation model that is not equipped with the myCASE telematics and multi-mode fuel management of the NX range.
Best for: Contractors requiring extra weight and stability for earthmoving in rough conditions.

The CASE 770NX MAGNUM runs a 4-cylinder turbocharged intercooled Stage V engine producing 74 HP. Operating weight is 7,700 kg. It digs to 4.70 m and comes with a 15-foot extendable dipper that adds 1.2 m of extra reach useful for deeper trenches without repositioning the machine.
The 1.1 cum loader bucket pairs with a 3,650 kg lift capacity for faster truck loading in fewer cycles. The hydraulics support simultaneous backhoe and loader operation, cutting idle time on busy sites.
Fuel management includes auto idle, auto shutdown, and ECO, Standard, and Power modes together saving up to 20% on fuel. The HVAC cabin keeps operators comfortable in both hot and cold conditions. LED work lamps allow night shifts without loss in output. The myCASE telematics tracks fuel use, uptime, and maintenance schedules in real time.
Best for: Contractors who need deeper digging, extended reach, operator comfort, and smarter hydraulics for long daily shifts on utility and drainage projects.

If your work is standard construction trenching, road drainage, and truck loading and fuel control matters, the CASE 770NX is the right machine. The ECO mode and myCASE telematics give you visibility over running costs every day.
If you do heavy trenching in compact or clay soil and need higher breakout force with a bigger loader bucket, go for the CASE 851NX. The 6,550 kgf breakout force and 143 LPM hydraulic flow are built for ground that pushes back.
If your sites are rough and uneven and you need a heavier machine for ground stability, the CASE 770 EX Plus at 7,955 kg holds its footing better than the rest. It is an older generation model but a strong, stable machine for tough terrain.
If you regularly dig deep utility trenches, need extra reach without moving the machine, and want HVAC comfort for long shifts, the CASE 770NX MAGNUM is the one to buy. The extendable dipper, simultaneous backhoe-loader operation, and LED lamps for night work make it the most complete machine in this group.
CASE offers four backhoe loader options for Indian construction sites, each built for a different priority. The 770NX suits fuel-conscious operators on standard sites. The 851NX handles heavy trenching and high-volume loading. The 770 EX Plus brings weight and stability to tough terrain. The 770NX MAGNUM adds reach, comfort, and smarter hydraulics for operators who need the most from their machine every shift.
