Kubota T1880, T2080, T2380 Common Problems This Manual Covers
Kubota T1880, T2080, T2380 engine will not crank or turns over slowly when turning the key p. 168
Check the battery terminals for corrosion and measure the voltage on page 168. Verify the reading is more than 12 V. Inspect the wiring diagram on page 157 for broken connections. Clean the terminals and charge the battery if the voltage drops below specification.
Manual Section: Electrical System Troubleshooting (General)Hydrostatic transaxle leaks oil underneath the transmission case or operates in one direction only p. 57
Inspect the transmission housing for cracks or damaged seals. Drain the fluid and torque the transaxle fluid drain plug to 1.70 N·m (0.17 kgf·m) as specified on page 57. Refill the hydrostatic transmission case with exactly 2.70 to 2.75 L of fresh fluid.
Manual Section: Hydrostatic Transaxle TroubleshootingMower belt slipping or blade does not rotate when PTO switch is engaged p. 35
Remove the mower deck covers and inspect the drive belt for excessive wear or glazing. Check the blade mounting hardware on page 35 and tighten the blade tightening torque to 103 to 117 N·m. Replace the belt and verify the PTO tension arm moves freely.
Manual Section: Mower TroubleshootingFront wheels wander to right or left and steering feels excessively hard during operation p. 31
Measure the front tire pressure and inflate to exactly 100 kPa (14 psi) as detailed on page 31. Inspect the steering linkage for bent tie rods or loose joints. Lubricate the king pins and adjust the toe-in to factory specifications to correct the wandering condition.
Manual Section: Front Axle TroubleshootingFrequently Asked Questions
What are the recommended service intervals?
Recommended service intervals include daily checks for fuel level, oil level, and air cleaner condition. Every 25 hours or annually, service the precleaner element. Every 100 hours or annually, replace the air cleaner element, change oil and filter, replace the fuel filter, and check all fasteners. Valve lash should be checked/adjusted every 200 hours, and spark plugs replaced every 500 hours.
What fluids and capacities does this machine require?
The engine crankcase for T1880 requires 1.5 L of API service classification SG, SH, SJ or higher oil (SAE 5W-20/30 below 0°C, SAE 10W-30 above 0°C). The hydrostatic transmission case requires 2.70 to 2.75 L of API service classification SL SAE 20W-50 oil. Fuel tanks vary from 13.5 L to 15 L, requiring automobile unleaded or regular gasoline with 87 octane or higher.
How to troubleshoot engine won't start?
If the engine won't start, common issues include a discharged or defective battery, a malfunctioning starter, or a blown slow blow fuse (G-45). Other causes can be a defective main switch (8-S8), an improperly set PTO switch (8-S10), or disconnected wiring harness (8-S7). For engines that crank slowly, check for a low battery charge (G-32, 33) or excessively high viscosity of fuel or engine oil (G-9).
What are the hydraulic system specifications?
The hydrostatic transaxle has an overall reduction of 27.49:1. Input speeds are 3600 rpm (maximum hi-idle) and 1800 rpm (minimum). Output torque is 445 lbf·ft (603 N·m) intermittent and 230 lbf·ft (312 N·m) continuous. The axle shaft diameter is 1.00 in. (25.4 mm), and the unit weighs 42 lbs (19 kg).
