ENGINE DETAIL
The Ursus 2812 tractor features a robust 2.5L 3-cylinder diesel engine with a rated output of 37.6 hp at 2000 RPM, providing sufficient power for light to moderate agricultural tasks. Its direct injection fuel system and 16.5:1 compression ratio enhance fuel efficiency while the oil-bath air cleaner minimizes maintenance by ensuring cleaner intake air. However, with only 106.2 lb-ft torque at 1400 RPM, it may face challenges in heavy-duty applications, making it ideal for smaller farms or less demanding work scenarios.

TRANSMISSION
The Ursus 2812 tractor features an 8-speed forward and 2-speed reverse gearbox, facilitating versatility in various agricultural tasks by allowing fine control over speed and torque. Its 305mm dry disc clutch provides reliable engagement under load, although it may require more frequent maintenance compared to wet clutches in heavy-duty applications. With an oil capacity of 33.8 quarts (32.0L), operators should ensure regular checks to maintain optimal lubrication and performance, especially in demanding conditions.

MECHANICAL
The Ursus 2812 features a 4x2 2WD configuration, which provides adequate traction for light to moderate fieldwork but may struggle in wet or muddy conditions. The mechanical rear differential lock enhances traction on uneven surfaces, while the 8-speed transmission allows for versatility in speed control across different farming applications. The optional two-post ROPS cab enhances operator safety and comfort but may limit protection in rollover scenarios compared to a full cab design.

URSUS 2812 TIRES
The Ursus 2812 tractor is equipped with standard agricultural tires, featuring a front tire size of 6.00-16 and a rear size of 12.4-28, which enhances traction and stability on various terrains. This configuration is ideal for moderate field work and can handle light tillage and hauling tasks effectively, although it may limit performance in extremely muddy or loose soil conditions. It's important to note that while these tire sizes provide a balance of flotation and grip, operators should consider upgrading to wider tires for improved flotation in softer soil scenarios.
