At least they are taking it in turns Brendan, Everything I own seems to want to go wrong all at the same time! Glad the HTD5 is going well, have you seen the electric one has new planetary hubs which might lead to improved tracking?
I've seen it, I like that they have added a step, I know electric is the future but the cost and all the hassle of having to charge it and can it manage a full day.
The original dumpster is hardly fast and the electric version is 1kmh slower, plus my biggest issue with it, is the sheer cost it's over double the cost of the diesel version.
Flat out all day I don't think mine uses £5 worth of white diesel with diesel version at around 6.9k plus vat, from a quick look for the two lease prices from JCB for both are just over double for both the lease hire/purchase options. With some quick maths someone could buy two for the same price

or based on £5 a day fuel for the diesel, you could run it for 1380 days or the equivalent of 5.75 years (5 days a week for 48 week's a year).
To be fair the cormidi I bought was cheap and had a few issues from day one, I'm certain it will need a regulator and the starter motor is also playing up the solenoid only engages every so often but it does start and work. The tracking power and speed is excellent the tipping and lifting is a bit pony
