College Day 16/03/2026

 Today I was introduced to Rotavators and got to practice with a Grillo GZ2.



Rotavators can be used for a multitude of reasons on soil. They can be used to aerate soil, prepare/ level soil for planting, uproot weeds, mix fertiliser etc. In terms of operation and architecture it feels very similar to a push-mower, so getting to grips with it only took seconds as I've used push-mowers at Maydencroft many times before.

Before operating, we did a quick visual Risk Assessment and discussed safety precautions one must take before partaking in the use of such equipment. 

Essential PPE would be:


  • Ear Defenders - the GZ2 produces 96db while the engine is running, anything above 85db requires ear protection
  • Gloves - A thicker pair of gloves would reduce the strength of the vibration caused by the machine on hands.
  • Foot Protection - Steel-toe cap Boots or other appropriate protective footwear would be required due to wear the tiller operates
  • Eye Protection - Although there is a guard above the tiller, there is always the chance debris could be ejected from the soil in the direction of the operative

  • In addition to PPE, the handling of fuels and oils should also be considered when using a rotavator. spillages could cause environmental damage and mishandling of petrols and oils could directly harm people.

  • Breaking ground also carries risks, even at a surface level, as services could be directly below if not placed in-line with regulation or even if it is but the rotavator is being used on pre-excavated ground. It would also be worth considering what effect it would have on wildlife when using the equipment, such as if habitats would be disturbed, does the soil contain invasive species or disease etc.

Scorecard Review

Image
As it has been around two months since my last scorecard review, I decided that another one was due as I have obviously learnt a lot more since mid-January.  The following criteria below are ones that I have increased my score in since the previous review: K2 - Ecology - I bumped up my score in this criteria because of what I learned recently while researching the soil triangle, pond habitats, pond weed and how flora that have rhizomes can rapidly overspread K5 - Common farming practices - I recently was introduced to the aforementioned soil triangle, I also did a blog on the farming calendar K8 - Countryside legislation - I increased my score on this criteria because of what I learn form the countryside pollution course that I did, which covered some of COSHH regarding how and where fuels, oils and chemicals can be stored as well as the penalties regarding harm/ disruption to invasive species such as newts, badgers and bats K12 - Map reading - I recently refreshed myself on taking...

Maydencroft Weekly Summary 18/11 - 21/11

Image
This Week (18/11 - 21/11) was set on two separate sites. One day on Terlings Estate - Which has a Veteran Cedar Tree (This one - HERE ) and is covered by all the protections/ maintenance that comes with it. This site was in Harlow and the other outside Potter's Bar by the M25. At Terlings I got practice in using a Pedestrian Mower, Leafblowing and changing Dog Litter bins. On the Potter's Bar site I learned about the sapling tree planting process, how to heel trees into the ground etc. We had a production line on the site: One man with a pointed spade going up the field left to right, opening holes One or two placing trees into holes and heeling them One or two placing in wooden post One knocking posts (who must always be wearing a hard hat) One or two placing on and attaching guards. I tended to jump between roles just so nobody catches up too close or falls too far behind of another step. Mulching the trees was also another step but it was done separately as getting the tree...
