Commercial delivery locations are preferred when available. Residential delivery, limited-access locations, and appointment scheduling may affect handling and extend delivery time.

Lead times vary by product, manufacturer availability, and selected options. Some configured, special-order, or non-stock items require additional processing time before they ship.

Please inspect all freight shipments at delivery before signing. If you see visible damage, note it with the carrier and contact us as soon as possible.

If you need freight, delivery, or lead-time guidance before ordering, contact our team before you purchase.

Compatibility / Fitment

Compatibility varies by product type, machine setup, selected options, and intended application.

For machine-mounted equipment and attachments, buyers should confirm fitment before ordering using the relevant machine information, including model, attachment style, mount type, coupler type, hydraulic requirements, and any other product-specific requirements listed on the page.

Hardscape Heavy can assist with pre-order fitment guidance based on the information you provide. This guidance is limited to purchase and compatibility review before ordering and does not include field installation, hydraulic modification, fabrication, or on-site setup support.

If you are unsure whether a product will work with your machine or application, contact us before placing the order.

Returns & Warranty

Warranty coverage is provided by the product manufacturer where applicable. Warranty terms, coverage periods, exclusions, and claim procedures vary by brand and product type.

Hardscape Heavy does not create separate warranty coverage beyond the manufacturer’s warranty unless explicitly stated on the product page.

Returns are governed by our store return policy. Because many products in this category involve freight shipping, special ordering, or configuration-specific selections, return eligibility may vary by product and condition. Special-order, custom-configured, used, damaged, or installed items may not be eligible for return.

Please review our full return policy before purchase. If you have questions about return eligibility or manufacturer warranty coverage for a specific item, contact us before ordering.

The KR52 turns a 76 horsepower tractor into a 52 kW source of standby and remote 120/240 single phase power, which is the whole case for a PTO generator: one less engine to own, fuel, service and start after months of sitting. It sits third in the four-model KR line, and it is built for contractors, utility and grounds crews, and service operations that already run a larger tractor and need power at a shop, a yard or a jobsite without buying a second engine to get it.

The genset is a cast-iron, four-pole, brushless alternator on four oversized copper windings, and an oil-filled gearbox steps the PTO input down to an internal speed well below engine speed, which the supplier ties to duty cycle: less friction, heat and wear over a long run. The four windings give momentary surge capacity of up to three times rated power, so a motor starting under load does not drag the voltage down, and automatic voltage regulation holds output within 1 percent from 64 down to 56 Hz. The DisplayMaster1 puts voltage, frequency, amperage, kW, kVA, power factor and run time on one screen beside a three-light over and under speed indicator, and reset circuit breakers clear a surge without hunting for a spare fuse.

Common Applications

  • Standby power for a shop, yard or service building during an outage
  • Remote power at a jobsite from a tractor already on site
  • Running equipment motors and hand tools away from a service
  • Field repairs with a portable welder on the 50 amp welder receptacle

Selection Notes

  • Size the tractor first. The KR52 draws 39 hp at 50 percent load and 76 hp at 100 percent load, and the 100 percent figure governs if the generator will run near its rating.
  • Wire Length is the run from the generator to the service. The supplier ships the KR52 with a 10 ft full power cord and prices its cable by the foot for a longer run, offered at 20, 30, 50 and 100 ft beyond the included 10 ft.
  • Phase Configuration is a cable configuration. The KR52 itself is a 120/240 volt single phase generator, and the supplier's cable table steps from a three-strand #2 cable at 45 kW to a three-strand 2/0 cable at 55 to 68 kW. Confirm the cable gauge and configuration against the service it will feed before ordering.
  • End Plug: the supplier's included cord carries a 175 AMP Anderson connector with four #2 pins, and its 350 AMP Anderson plug carries four 2/0 pins, the gauge the supplier pairs with its 55 to 68 kW cable. The KR52's full output is 225 A at the main breaker.
  • The three point hitch deck is an added-cost option in place of the trailer. The supplier's 52 to 105 kW deck, D001434, begins at the KR52's own rating; give the model when ordering.
  • Never mount a generator directly onto concrete, rock, metal or soil. The supplier's rubber mount kit, D001478, four isolators to a set, goes under the tires on a concrete pad.
  • The trailer jack, G2107, is a separate part.
