Tractor Complete Guide
Front Loaders, Differential Locks, Wheel Weights & 3-Point Hitch Explained
Professional Answers from Shandong Lifetree Machinery Co., Ltd. — 25-300HP Tractor Manufacturer
Tractors are indispensable power equipment in modern agriculture and engineering operations. Whether in field farming, orchard management, or construction sites, tractors deliver outstanding performance. However, many operators and farm owners don't fully understand the various functional components of their tractors. Today, Shandong Lifetree Machinery Co., Ltd. provides detailed answers to common tractor questions, helping you maximize the value of your equipment.
A front loader is a versatile attachment mounted on the front of a tractor, widely used in agriculture, livestock farming, and construction.
● • Material handling: Transporting feed, fertilizer, seeds, timber, and other agricultural supplies
● • Loading & unloading: Loading grain, soil, sand, and other bulk materials
● • Site cleaning: Clearing manure, compost, snow, and debris
● • Construction work: Excavating foundations, leveling ground, and moving building materials
● • When installing a front loader, always add counterweights to the rear wheels to maintain the tractor's center of gravity
● • Drive at low speeds when lifting heavy loads and avoid sharp turns
● • Never carry heavy loads laterally on slopes to prevent rollovers
Shandong Lifetree Machinery Co., Ltd. offers 25-300HP tractor series, all compatible with major front loader brands. 24/7 WhatsApp: +86 178 6293 9397
The first low gear (1st Low / Creeper Gear) is the lowest speed setting in a tractor's transmission, providing maximum traction and minimum travel speed.
● • Heavy-duty plowing: Deep tillage with large plows requires low-speed, high-torque output
● • Steep hill climbing: Low gear delivers superior pulling power on hilly or mountainous terrain
● • Precision operations: Planting, transplanting, and other tasks requiring precise speed control
● • Heavy towing: Pulling loaded trailers or dump carts on soft ground
● • First low gear typically operates at 0.5–3 km/h
● • Engine RPM stays high while travel speed remains low, maximizing torque output
● • Not suitable for prolonged high-RPM operation; shift gears according to load conditions
The differential lock is a critical safety and functional component in a tractor's drivetrain. When one drive wheel slips, it forces both wheels to rotate in sync.
● • Muddy ground: One wheel stuck in a mud hole while the other spins freely
● • Loose sand: Insufficient tire traction on sandy terrain
● • Slope operations: Reduced grip on one side of the tractor
● • Snow & ice: Slippery, snow-covered surfaces
Situation | Use Differential Lock? |
Straight-line driving with one wheel slipping | ✅ Yes |
Turning or cornering | ❌ Never |
Flat, hard-surface roads | ❌ Not needed |
Muddy/soft ground, straight travel | ✅ Yes |
⚠️ CRITICAL WARNING: Never engage the differential lock while turning. Doing so can damage the drivetrain or cause a rollover!
A tractor is a self-propelled agricultural machine powered by an engine, serving as the core equipment of modern farming.
● • Plowing, rotary tilling, deep loosening, harrowing
● • Land leveling, furrow ridging
● • Pulling precision planters for accurate seed placement
● • Operating fertilizer spreaders for base and top dressing
● • Towing combine harvesters
● • Hauling grain, straw, and feed from the field
● • Irrigation pumping (PTO-driven water pumps)
● • Power generation (PTO-driven generators)
● • Landscaping and orchard management
● • Livestock feed processing
Wheel weights and counterweights are heavy attachments installed on the tractor's wheels or frame to balance the machine's center of gravity.
● • Rear-mounted heavy implements: When using large plows or rotary tillers, added rear weight can lift the front wheels, causing loss of steering
● • Front loader operations: When the loader lifts heavy loads, the rear needs sufficient counterweight to maintain balance
● • Hillside work: Proper weight distribution improves traction and stability on slopes
● • Front wheel weights: Cast iron blocks mounted on front wheel rims or front axle frames
● • Rear wheel weights: Mounted on rear wheels to increase drive wheel traction
● • Liquid ballast: Filling tires with water (usually mixed with antifreeze) to add weight
Pro Tip: Balance front and rear counterweights according to your specific operation. Shandong Lifetree tractors offer multiple counterweight options. WhatsApp: +86 178 6293 9397
The 3-point hitch (3-point linkage) is the most essential implement attachment system on modern tractors, invented by British engineer Harry Ferguson — also known as the "Ferguson System."
● • Top Link: 1 link connecting the top of the tractor to the implement
● • Lower Links: 2 links connecting the bottom of the tractor to the implement
● • The three points form a stable triangular connection
Function | Description |
Implement attachment | Quick-connect plows, rotary tillers, planters, and more |
Lift & lower | Hydraulic control of implement height |
Depth control | Precise tillage depth via draft/position control |
Draft sensing | Automatically adjusts depth based on soil resistance |
Transport mode | Raises implement to transport position for safe road travel |
● • Category I: Small tractors (20-50HP), pin diameter 19mm (3/4")
● • Category II: Medium tractors (40-100HP), pin diameter 22mm (7/8")
● • Category III: Large tractors (80-200HP), pin diameter 28mm (1-1/8")
● • Category IV: Extra-large tractors (200HP+), pin diameter 36mm (1-7/16")
Choosing the right tractor-mounted mower depends on property size, terrain conditions, and mowing frequency.
Property Size | Recommended Equipment | Required Tractor HP |
1-5 acres | Walk-behind mower | No tractor needed |
5-20 acres | Small tractor + side-mount mower | 25-50HP |
20-50 acres | Medium tractor + rear rotary mower | 50-80HP |
50-200 acres | Large tractor + sickle bar mower | 80-150HP |
200+ acres | High-HP tractor + multiple mower units | 150-300HP |
● • Lawn / pasture: Rotary mower (flail or finishing type)
● • Hay / forage: Sickle bar mower (reciprocating knife)
● • Orchard inter-rows: Offset mower
● • Uneven terrain: Flex-wing mower
