Mahindra 2615 Troubleshooting
The
Mahindra 2615 compact utility tractor was manufactured by Mitsubishi built
between 2003 and 2008. The Mahindra 2615 tractor is powered by Mitsubishi S3L2
4-cycle 3-cylinder indirect injection naturally aspirated water-cooled diesel
engine. A 80.4 cubic inches (1.3 L) engine has a cylinder bore of 3.07" (78 mm),
piston stroke of 3.62" (92 mm), and rated power of 26 hp (19.4 kW). The Mahindra
2615 is fitted with a two transmission options: 9x3 constant mesh transmission,
or 3-range hydrostatic transmission.
The maximum forward speed - 11.7 mph (18.8 km/h), maximum reverse speed - 6.2 mph (10 km/h). The open center hydraulic system includes a gear pump with rated fluid flow of 7.8 gal/min (29.5 l/min). The main relief pressure is 156 bar (2250 psi). The tractor is equipped with a hydrostatic power steering system, wet disc brakes, 7.00x16 or 25x8.5-14 front tyres, and 11.2x24 or 13.6x16 rear tyres. The tractor is compatible with Mahindra ML106 front end-loader with a max lift height of 96.5" (2450 mm).
