KK13 Mini Excavator Review: The Purchaser’s Experience
A factual account of one purchase of a KK13 Mini Excavator from Shandong Gaohe J.M. Machinery Co., Ltd, also promoted as United J.M. Machinery. This page separates documented facts, supplier message wording, the purchaser’s account and personal opinion.
Order overview
The order concerned a KK13 Mini Excavator. The order screenshot shows a price of US$9,070. The supplier named on this documentation is Shandong Gaohe J.M. Machinery Co., Ltd, also promoted as United J.M. Machinery.
Stated specification
The machine was described as using a Kubota D902 engine. This website reports that description as it appeared in the purchase materials. It does not independently certify engine identity, build quality or conformity marks beyond the documents and photographs presented in the evidence archive.
Early use and work completed
According to the purchaser, the machine was used for light-to-moderate work before the failure. Described tasks included trenches, shallow foundations, mud and aggregate loading.
This site does not invent utilisation logs, duty-cycle data or operator qualifications that were not supplied.
Operating hours
The purchaser stated that the machine had completed approximately 40 operating hours before the structural failure. That figure is presented as the purchaser’s account.
Onset of failure
The chassis or welded structural section failed. The purchaser described the machine as separating around the welded structural section joining the track assembly to the main body. The purchaser said the structural failure also damaged internal components and left the machine unable to start.
The later repair invoice described defective welding on the section joining the tracks to the main cab body. See the chassis failure page for cautious technical wording based on that invoice.
Downtime
According to the purchaser, the machine could not be returned to service until local engineering work was completed. This page does not invent a precise downtime calendar beyond that account and the dated repair invoice of 28 December 2025.
Supplier response
Supplier messages stated that the machine would be repaired. The supplier told the purchaser to find a local repairer and wrote that it would cover the repair and logistics costs. Later messages stated that customers normally find a repair factory themselves and that the supplier would bear all costs.
After the invoice was submitted, the supplier acknowledged receiving the repair bill and said it had been forwarded to the after-sales department. Further messages referred repeatedly to waiting for after-sales. The supplier also discussed the possible purchase of another machine or flail mower.
According to the purchaser, reimbursement was not received.
What was positive before the failure
This section does not invent product strengths. The documented points are limited to the following:
- The machine was used for the described light-to-moderate tasks before the failure.
- The supplier initially engaged with the complaint in writing and discussed a repair path.
Those points do not amount to a finding that the machine was fit for long-term use, nor do they resolve the later reimbursement dispute.
Final opinion
The following statement is the purchaser’s personal opinion, not an independent laboratory finding:
Based on this experience, the purchaser would not buy from this supplier again.
Readers should review the evidence — including the repair invoice, supplier messages and evidence archive — and reach their own conclusions.
