This is post 2 of this build post 1 of the Two Wheel tractor project is here<\/a><\/p>\n

Another couple of nights later and I had cut the swinging arm in half and extended it with some tube. Now I could see how it would all go together:<\/p>\n

\"walking<\/a>

First view how the two wheel tractor will come together<\/p><\/div>\n

Looks all right to me so I raided my pile of rusty steel bar, tube and angle\u00a0 to connect the bike frame to the wheels.\u00a0 The critical addition connects the headstock and front down tube to the wheels.<\/p>\n

\"Motorbike<\/a>

The finished tractor frame, with the bits that make it go<\/p><\/div>\n

OK the picture skips forward a bit. I took this after its maiden trip up and down the back lane.\u00a0 Thankfully the after about 13 years the engine started, once I got the fuel running and unblocked the air filter.\u00a0 So skipping back, there where lots of fiddly bits to sort out:<\/p>\n

THE DRIVE<\/strong><\/p>\n

\"Chain<\/a>

An Extra 3:1 reduction cobbled together<\/p><\/div>\n

From the Engine to the original rear wheel sprocket. Welded to some bar, through a good fitting tube, connected to the CB550 engine sprocket. And I got all technical by adding a grease nipple to the tube.\u00a0 The tube is on a hinged plate\u00a0fitted with an adjuster to tension the chain to the engine. the final drive chain is tensioned using the original adjusters on the swinging arm.\u00a0<\/p>\n

THE CLUTCH<\/strong><\/p>\n

I splashed out some time here on a ” safety feature” . Reversing the operation of the clutch so that pulling the handlebar lever engages the clutch.\u00a0 Letting the lever go acts as a “Dead Man” . this also means I can change gear\u00a0 by hand.<\/p>\n

\"Motorbike<\/a>

reversed clutch set up, fully adjustable<\/p><\/div>\n

The spring, I think, was from the original\u00a0back brake lever. This pulls the the clutch arm like the normal cable would so the clutch is disengaged. The clutch cable now pulls the arm in the opposite direction when the handlebar lever is pulled, hence engaging the clutch.<\/p>\n

THE BRAKES<\/strong><\/p>\n

I thought brakes might come in handy\u00a0especial going down hill with loaded trailer.\u00a0<\/p>\n

\"Adapted<\/a>

Simple adaptation to operate via original front brake lever<\/p><\/div>\n

The original drum brake, control arm and pull rod fitted straight on. The trick was to connect the pull rod to the front brake cable.\u00a0 Small thought, Little action and it works.<\/p>\n

GEAR CHANGE<\/strong><\/p>\n

\"gear<\/a>

Hand controlled gear change lever<\/p><\/div>\n

A tube held on the foot lever with jubilee clip, connects to a short hand lever. The lever is sprung loaded to centre itself.\u00a0 It’s surprisingly easy to select gears and find neutral afterwards.<\/p>\n

THE ELECTRICARY<\/strong><\/p>\n

Down to almost the bare minimum.\u00a0 Almost minimum? Well an on \/ off switch is a luxury I can cope with.\u00a0\u00a0<\/p>\n

Starting at the beginning:\u00a0 Alternator – two wires to rectifier –\u00a0Negative out to frame – positive up to the headlamp switch – switch to coil – coil to condenser and points – HT to spark plug.\u00a0 Keep it simple!<\/p>\n

KICK START<\/strong><\/p>\n

\"Modified<\/a>

Kick start where I can get to it<\/p><\/div>\n

The bottom joint welded up and “T” piece on the top. Fits nicely between the frame and gives almost the full swing.<\/p>\n

THE EXHAUST<\/strong><\/p>\n

\"Bike<\/a>

For that proper tractor feel, the exhaust sticks straight up<\/p><\/div>\n

\u00a0Only one curve adjustment on the down pipe, or should that now be up-pipe.\u00a0 And A bit of\u00a0angle welded to the frame give some extra support to the silencer.<\/p>\n

CHUG CHUG CHUG<\/strong><\/p>\n

It looks the part, especially when you now what “the part” is.\u00a0 More importantly in runs, bags of torque and I’m sure I’ll get used to the\u00a0handling.\u00a0\u00a0 It needs a few bits ‘n’ bobs tidying, tightening\u00a0, cleaning and\u00a0greasing.\u00a0Then some thought going in to the trailer hitch.<\/p>\n
