Operating Weight Range:
Approx. 1,200 lbs (B700D) to 2,500 lbs (L275), excluding ballast and implements.
Features:
Minimal to none. Basic instrumentation (tachometer, temperature gauge, fuel gauge, warning lights).
Features:
Power steering is a common convenience feature on many of these models.
Features:
N/A (Tractor technology from an era prior to digital connectivity).
Engine Oil Change:
Typically every 50-100 hours or annually, depending on operating conditions.
Air Filter Service:
Check and clean at 50-hour intervals, replace as needed.
Fuel Filter Replacement:
Typically every 200-300 hours or annually.
Engine Oil:
Kubota UDT Fluid or SAE 10W-30/15W-40 API CD or CE classification, capacity ~3.5-5 qts.
Transmission Hydraulic Fluid:
Kubota UDT Fluid (Universal Transmission Drive), or equivalent (e.g., John Deere Hy-Gard), capacity varies significantly by model.
Coolant:
Ethylene glycol-based antifreeze, 50/50 mix with water, capacity ~3-5 qts.
Grease:
Lithium-based grease, EP type for universal joints and pivot points.
Hst Concerns:
Hydrostatic transmission (HST) wear or failure can occur with age and lack of proper fluid maintenance. Overheating can also be an issue if cooling fins are blocked.
Diesel Particulate Buildup:
While these are older models without complex emission controls, carbon buildup in combustion chambers can occur with prolonged low-load operation.
Hydraulic Leaks:
Worn seals in cylinders, pumps, and hoses are common due to age and usage.
Electrical Connector Corrosion:
Corrosion on electrical connectors and grounds due to exposure to elements.
Manufacturer:
Kubota Corporation, a Japanese company founded in 1890, renowned for its agricultural machinery, construction equipment, and engines.
B Series Evolution:
The B-series started as very compact utility tractors and evolved into more feature-rich sub-compact models. The B700D and B7100HST.E represent earlier iterations of this line.
L Series Evolution:
The L-series has historically offered a range of larger compact tractors with more power and hydraulic capacity, suitable for a broader array of farming and property maintenance tasks. Models like L185, L235, L245, and L275 are part of this lineage.
Production Era:
These models primarily hail from the 1970s through the 1990s, with some variations and potential overlap.
