When it comes to horsepower, it's important to have a high-flow circuit and an engine of at least 70 hp, Slattery notes. Most current production tractors equipped with high flow have 70 to 100 hp engine options and high flow circuits that produce adequate hydraulic power for mulching. At least one 70 hp engine should be included in a high-flow circuit when deciding on horsepower, Slattery says. In general, high-flow tractors have a valve system that generates between 70 and 100 horsepower with corresponding hydraulic power for shredding machines.
In terms of thickness and terrain, the machine can clean up to 1 acre of soil in a day. It will take you between 8 hours and 3 acres to brush, heather, root trees or grow small trees and brush them on flat ground as well. Low, medium, high and extremely high horsepower tractor forestry grinders for shredding wood, trees, shrubs, stumps and roots up to 20-inch diameter requirements. Most current production machines with 70-100 hp motors, and equipped with high-flow circuits, will have adequate hydraulic power for cushioning.
