ALLIS CHALMERS 620 POWER
ENGINE DETAIL
The Allis Chalmers 620 tractor features a compact Onan CCKB engine with a displacement of 49.8 ci (0.8L) and a modest 19.5 hp output, suitable for light-duty applications like gardening or small farm tasks. Its 7:1 compression ratio and 3600 RPM rated speed indicate a balance of efficiency and reliability, although the limited power may constrain heavier implement work. The paper element air cleaner and 3.5 qt oil capacity enhance maintenance requirements, emphasizing the need for regular checks to ensure optimal performance.

TRANSMISSION
The Allis Chalmers 620 features a hydrostatic transmission that offers seamless speed control without gear shifting, ideal for tasks requiring precision, such as towing or loader work. Its infinite forward and reverse gears across three ranges enhance versatility, allowing for adaptable performance depending on the terrain and load. However, hydrostatic systems may require more maintenance and could face overheating issues under heavy use; thus, monitoring hydraulic fluid levels and temperatures is crucial for prolonged operation.

MECHANICAL
The Allis Chalmers 620 tractor features a 4x2 2WD chassis, providing good maneuverability in flat terrains but limiting performance in challenging conditions like mud or hills. Its open operator station offers ease of access and visibility, though it sacrifices protection from weather elements. The hydrostatic transmission enables smooth and responsive speed control, ideal for tasks requiring precision, such as gardening or light agricultural work.

ALLIS CHALMERS 620 TIRES
The Allis Chalmers 620 tractor features versatile tire options, with agricultural front tires (4.00x12) and rear tires (8x16) for field applications, alongside larger lawn/turf configurations that facilitate better traction and comfort on grass (20-8x10 front and 29-12.5x15 rear). This adaptability enables efficient operation in various environments, from agricultural tasks to lawn care. However, the use of larger turf tires may compromise maneuverability in tight spaces, making it less suitable for precision landscaping tasks.

DIMENSIONS & TIRES
The Allis Chalmers 620 tractor, with a compact wheelbase of 56 inches, enhances maneuverability in tight spaces, making it ideal for small farms or yard work. Its relatively lightweight design at 1,500 lbs aids in reducing soil compaction but may limit stability on uneven terrain, necessitating caution during operation. The tire sizes (4.00x12 front and 8x16 rear) provide a balance between traction and flotation, beneficial for light-duty tasks on various soil conditions.
