Old PTO shaft.

[rick_vandal]

I have just changed a 400 year old universal joint on my Rotavator for something newer. No kidding, the Hookes joint has been around that long with all it's limitations even at 540 RPM and 20 degree angles it rattles. Academics will claim that the second joint cancels out the speed variations but that doesn't happen with a sloping top-link (nor on a trailed implement). Said CV joint works at 40 degrees with a good torque capacity.

Is that a hydraulic stabiliser? Never seen that on a Leyland before.

It is just a small single acting ram for nudging the plough across for the Ins. Useful for hitching too.

You lunatic.

I like that.

It is not about the tractor but you could try to find the ten differences in this photo!

Hmm.. racing spec steering wheel is the obvious one. Is that the stop pull coming out of the top of the bonnet?

Left hand mud guard cut away? Clutch pedal looks like it's narrower than normal. What's the red button thing on the bottom left of the dash?

Struggling to find 10. Are you counting the non-standard tool box and front tyres?

Wheel is from a Westwood mower, is big enough with PAS. Clue; 10 speed box levers?

 

[David1968]

Ah, have you extended the gear levers? Bit hard to tell with that chunky steering wheel in the way

 

[rick_vandal]

Left wing cut back, white turntable added, clutch pedal halved, roller fitted under floor left of pedal, PTO clutch pedal pruned, stop knob repositioned, small steering wheel, windscreen bolted shut, gearstick removed, HI/LO lever turned 180 is ten. The red button is indicators.
Other stuff, a corded 12 volt drill on the levelling box, lowered lower link front pins, said sideways ram. Not shown, the negative assistor ram with PRV to push the plough into work, a horizontal exhaust for a clear view forwards, a huge truck mirror in the cab for a panoramic view backwards and those two bottom hex sets on the dry brake covers have been shortened too.
My plough is also a hybrid with an electric actuator on the cross-shaft, cheap and easy.

Front tyres are ex Defender 7.50-16 at 110 profile and were £15 each hard on rims. Rear tyres are crossply in the furrow and a Radial on-land. Toolbox fits and is better than the wedge beside the seat..

Selector shaft changed to exit from gearbox rear. Rotary and linear actions given by secret linkage and levers.

What class are you ploughing in with mods to it like that?

( Im assuming that it’s for competion ploughing)

Any Class! SOP specifically ban hydraulic operations (even though Ransomes used them) yet electric is cheaper.

Back on topic, said PTO shaft is the 540 variety, so is often transmitting 200 to 300 lb ft of torque!

 

[rick_vandal]

At 540 RPM, a 2' diameter FWD car tyre would be doing 38 MPH with power being shared by two CV joints. If a car in first gear has a 10:1 gear reduction, there is a tenfold torque increase (tyre to tarmac permitting).
