Background of the Bobcat 753G
The Bobcat 753 series, introduced in the mid-1990s, became one of the company’s most popular skid steer loaders. The 753G, an improved version launched toward the late 1990s, was designed for versatility and durability in construction, landscaping, and agricultural applications. It was equipped with a 43–46 horsepower Kubota diesel engine, a rated operating capacity of about 1,300 lbs, and a tipping load near 2,600 lbs. The machine weighed approximately 4,800 lbs, making it compact enough for tight job sites while still powerful enough to handle digging, lifting, and grading tasks.
Bobcat, founded in 1947, established itself as a leader in compact equipment. By the time the 753G was in production, Bobcat skid steers were being sold globally in large numbers, with annual sales of compact loaders exceeding tens of thousands of units. The 753G in particular found success due to its reliability, relatively low fuel consumption, and compatibility with a wide range of attachments.
Common Issues with the 753G
While the 753G is known for reliability, certain recurring issues arise with age and use:
When troubleshooting a Bobcat 753G, a structured process avoids unnecessary part replacements:
On many farms and construction sites, operators have reported frustrating downtime when the 753G refused to start after sitting overnight. In one documented case, a faulty ground strap between the engine block and frame was the culprit, causing intermittent electrical failures. After replacement, the machine performed reliably for years.
Another owner shared that contaminated diesel fuel led to recurring stalling until the tank was flushed and filters changed. This highlighted the importance of clean fuel and preventive maintenance in older skid steers.
Preventive Maintenance Recommendations
Despite being over two decades old, the Bobcat 753G continues to serve small contractors and farmers around the world. Its simple mechanical design, compared to today’s heavily computerized equipment, makes it easier to repair in the field. Parts remain available through aftermarket suppliers, and used units in good condition often command strong resale prices.
Conclusion
The Bobcat 753G is a proven workhorse with a strong legacy in compact construction machinery. Its main challenges often stem from electrical and fuel system issues, but with methodical diagnostics and consistent maintenance, these machines can remain productive for decades. For buyers considering a used 753G, careful inspection of the starter system, wiring harness, and fuel delivery components will prevent unexpected downtime and ensure a reliable investment.

Common Issues with the 753G
While the 753G is known for reliability, certain recurring issues arise with age and use:
- Electrical System Failures
Many operators report problems with starting, often linked to weak relays, corroded grounds, or worn ignition switches. Since the machine relies on electronic safety interlocks to ensure safe operation, any failure in the wiring harness or seat bar sensor can lead to no-start conditions.
- Fuel System Complications
Air in the fuel lines, clogged filters, or a malfunctioning lift pump may prevent the engine from firing. Because the Kubota diesel requires consistent fuel pressure, even minor leaks or blockages can cause stalling or complete shutdown.
- Hydraulic Lockout Problems
The skid steer uses a hydraulic interlock system tied to operator presence. If sensors under the seat or on the control handles fail, hydraulics will not engage. Many users confuse these malfunctions with engine problems, when in fact the engine runs but hydraulics remain locked.
- Starter and Solenoid Wear
After years of operation, the starter motor and solenoid are frequent points of failure. Symptoms include clicking sounds with no crank, sluggish turnover, or intermittent starting.
When troubleshooting a Bobcat 753G, a structured process avoids unnecessary part replacements:
- Battery and Connections
- Check voltage under load (should remain above 10.5V while cranking).
- Inspect terminals for corrosion and cables for internal resistance.
- Check voltage under load (should remain above 10.5V while cranking).
- Ignition and Relay System
- Test key switch continuity.
- Verify relays click and pass current when activated.
- Replace worn or burnt fuses.
- Test key switch continuity.
- Fuel Delivery
- Bleed air from lines at the injectors.
- Replace primary and secondary fuel filters.
- Inspect fuel shutoff solenoid for correct operation.
- Bleed air from lines at the injectors.
- Starter and Alternator
- Bench test starter for torque and draw.
- Confirm alternator output is 13.5–14.5V under load.
- Bench test starter for torque and draw.
- Safety Interlocks
- Inspect seat switch, seat bar sensor, and hydraulic interlock solenoid.
- Bypass temporarily for testing, but restore functionality for safe use.
- Inspect seat switch, seat bar sensor, and hydraulic interlock solenoid.

Another owner shared that contaminated diesel fuel led to recurring stalling until the tank was flushed and filters changed. This highlighted the importance of clean fuel and preventive maintenance in older skid steers.
Preventive Maintenance Recommendations
- Replace fuel filters every 250 hours.
- Inspect electrical connections monthly, especially in humid or corrosive environments.
- Test battery health twice a year.
- Service hydraulic fluid and filters every 500 hours.
- Keep spare relays and fuses on hand to minimize downtime.
