Tractors

One of the most useful vehicles ever constructed is the agricultural tractor. While it might seem a strange topic for a post this will probably be one of the most critical vehicles for non-military activity.

The Ursus ('Bear') tractors were famous for rugged simplicity and reliability in a time when western tractors were growing in complexity and cost which came with a commensurate lessening of reliability. Poland, being a country with a large agricultural sector, had many indigenous agricultural plant companies and a thriving import/export trade in this equipment.

During the Twilight period Ursus in Poland had been producing many tractors, here is three versions:

- Ursus 2812 (light tractor). 2,000kg, 25km/h, 60 litre (D,A), Equipment: Hydraulic Three Point Hitch (lift 1,300kg), 28Kw Power Take Off, Pulley - 21.0L/Period working, 10L/Period on road

- Ursus 1014 (medium tractor). 4,000kg, 25km/h, 90 litre (D,A), Equipment: Hydraulic Three Point Hitch (lift 3,000kg), 60 kw Power Take Off, Pulley - 45.0L/Period working, 22L/Period on road

- Ursus 1614 (heavy tractor). 5,000kg, 25km/h, 200 litre (D,A), Equipment: Hydraulic Three Point Hitch (lift 5,500kg), 100Kw Power Take Off, Pulley, 4x4 - 70.0L/Period working, 35L/Period on road

(0.75l/period x Kw)

A three point hitch is the adaptor point for machinery and includes a hydraulic system. The lift value is the maximum weight of an attachment.

A power take-off is normally a drive shaft running out of the engine to provide motive power for an attachment. Like the three point hitch it is an adaptor point (important note: these can be incredibly dangerous)

A pulley is simply a wheel that transfers power by pulley action.


Attachments:

Tractors are only the motive power, they are mainly made useful by their attachments. In Twilight 2000 they are either using their traction via tow cables, towing a trailer or attached to machinery such as ploughs or diggers.
Trailers.


Trailers

Generally a tractor can tow twice their weight so it may be possible to tow some of the following trailers at reduced load.

- Single Axle Livestock Trailer, 3.5 Tonne
Weight: 1,800kg, Load: 3,700kg, Max Speed 40km/h, Required power 20Kw, Notes: Rear loading doors, unroofed, rear ramp, spare wheel. Capacity: 4x 700kg animals, 6x 550kg animals

- Single Axle Livestock Trailer, 7.5 Tonne
Weight: 3,150kg, Load: 7,850kg, Max Speed 40km/h, Required power 30Kw, Notes: Rear loading doors, side access doors, roofed, rear ramp, spare wheel. Capacity: 8x 700kg animals, 10x 550kg animals

- Single Axle Utility Trailer, 2.5 Tonne
Weight: 1,300kg, Load: 2,400kg, Max Speed 40km/h, Required power 20Kw, Notes: spare wheel

- Double Axle Utility Trailer, 4 Tonne
Weight: 3,100kg, Load: 4,000kg, Max Speed 40km/h, Required power 25Kw, Notes: spare wheel

- Double Axle Bale Trailer, 9 tonne (low flat trailer with no sides for hay bales)
Weight: 1,950kg, Load: 8,900kg, Max Speed 40km/h, Required power 80Kw, Notes: spare wheel

- Double Axle Bale Trailer, 15 tonne (low flat trailer with no sides for hay bales)
Weight: 4,800kg, Load: 15,800kg, Max Speed 40km/h, Required power 45Kw, Notes: spare wheel

- Tandem* Tipping Trailer, 13 Tonne (*two rear wheels, no front wheel)
Weight: 5,200kg, Load: 13,200kg, Max Speed 40km/h, Required power 75Kw, Notes: spare wheel, this vehicle has 4mm walls 1.8m high

- Single Axle Dump* Trailer, 8 Tonne (low, fixed trailer. Lifts up at the front on hydraulic rams)
Weight: 2,200kg, Load: 8,100kg, Max Speed 40km/h, Required power 45Kw, Notes: Rear folding gate.

- Tandem Utility Trailer, 13 Tonne (high sided, rear ramp trailer)
Weight: 10,800kg, Load: 13,200kg, Max Speed 40km/h, Required power 135Kw, Notes: Rear folding gate, 2.2m high 1mm sides


Plant

Backhoe
Each backhoe has a seat, jacks to raise the tractor off the ground and a digger arm. Excellent for making deep trenches.
28Kw: 330kg
60Kw: 430kg
100Kw: 530kg

Front End Loader
A large bucket on the front of the tractor that lifts up and tilts for moving bulk material. Good for quickly creating earthworks and vehicle hides.
28Kw: 300kg
60Kw: 400kg
100Kw: 500kg

Auger
A honking great big drill for making deep holes in the ground. Excellent for making sturdy anti-vehicle barriers.
28Kw: 100kg
60Kw: 200kg
100Kw: 300kg

There are far more attachments but they are dedicated agricultural tools. Generally a farm would have three times its weight in tractors in these pieces of equipment
